A history of the development of the sweeper

Automatic floor sweeping robots first originated from where in fact has been untraceable, human attempts to free themselves from household chores for thousands of years has never stopped. The first electric floor sweeper that can be documented was Hitachi's HCR-00 at Domotechnica in 1985, after which Electrolux, LG, and even Dyson all released their own floor sweepers one after another. Unfortunately, these products were either too expensive or too retarded and didn't make much of a splash in the market.

It wasn't until 2002, when iRobot launched Roomba, the first truly modern sweeping robot, that this new tool for liberating humans from household chores officially entered the history books. Although Roomba's cleaning efficiency is not bad, its intelligence level is still very low, basically belongs to the random cleaning mode (intellectual sweeping robot), not able to effectively carry out comprehensive coverage of the house cleaning.

After Rommba, in the field of sweeping robots and many NB companies have joined, such as the famous Samsung, Hitachi, Coors, Taiwan Songteng and so on, but this stage of sweeping robots are still in the technical exploration period, with the current vision, they come out of the product is not much different from Rommba, are typical of the intellectual disability products.

In 2010, Neato invented the low-cost SLAM (360-degree rotating laser range finder) radar and installed it on its first generation of sweeper Neato XV-11. This radar can monitor the surrounding environment in real time and process the data obtained from the sensor by SLAM algorithm to build an indoor map, which enables the sweeper to achieve the function of global path planning. This is also a common application of technology for flooring robots on the market today. However, although the technical breakthroughs, but the market for sweeping robots is still in a period of high-priced operation, product prices remain high, the pace of entry into ordinary households is very slow.

Time flashed to 2016, when still in the Mijia ecosystem stone launched their first generation of LDS SLAM Mijia sweeping robot, and its price range a hammer smashed to 1699 yuan after the sweeping robot this category of appliances is truly opened into the ordinary family footsteps, and by the stone opened this crazy technology within the volume of the sweeping machine war, it has been played until today.

Second, the current market status of the sweeper and the degree of intelligence

When it comes to the development of domestic sweeping robots, I personally believe that is in the middle of a period of rapid development. After nearly 3 years of crazy in-volume, as well as the perfection and popularity of various hardware, the current market can be seen in different manufacturers of high-end sweeper models, have two similar technical characteristics.

1) is configured with high-end navigation devices

Top-mounted LDS is the main focus, supplemented by front vision or depth sensors, and there is even the use of Apple FaceID-like technology, not only to plan fixed navigation routes, but also to intelligently identify the type of various obstacles and make different obstacle avoidance processing.

2) It is a full-featured base station

At least with cleaning mop and automatic dust collection function, a little pursuit will be added to kill the poison, mop drying and other small functions to enhance the user experience. As for the automatic water and sewage, it is slowly starting to appear in the top models of major manufacturers.

As for other value-added features such as intelligent voice control or electrolytic water killing, they vary according to the preferences of different manufacturers and are considered a plus.

Intelligent degree and future imagination

The current high-end sweeper has basically freed people from sweeping and mopping the floor, you only need to move your fingers every week or even every month to empty the dust collection box of garbage on it. But there is still room to go further for identifying, sorting, cleaning and marking items on the floor.

For example, a slipper in the living room, the current sweeper with camera AI recognition function (such as the stone G10S Pro) can already identify it as a slipper, and in the process of sweeping the floor to mark it upload photos to your app, in the future it may have a robot arm, in sweeping the floor at the same time this slipper to you automatically put in the shoe closet.

Second, the future of the sweeper may also be your intelligent housekeeper. For example, you want to go out, found that the car keys can not be found, you can voice call the sweeper: where is my car keys. Sweeper: master, I found it fell on the floor when cleaning today, has been received for you on top of the TV cabinet!

The development of technology has brought us infinite possibilities for the future, the above examples are likely to be a direction of intelligent development of the sweeper.

Three which product is more worth buying

In order to do this period of activity, I collected the top four manufacturers on the market at present the reputation and heat ranking of the highest comprehensive models, respectively, chase for W10 Pro, stone G10S Pro, Coors X1 OMNI, cloud whale J2. can be said to represent the current top level of each sweeper, but also the entire sweeper market is currently a microcosm of the highest level. Let them have a wonderful collision, to see who in the end strength is better, who is more worth buying.

Written before the test words: In order to give readers a more objective purchase advice, this cross-evaluation test spent a total of nine days, in addition to working during the day, the evening and weekend time all used to test test test. All the data are real test to come, some of the sub-projects in order to accuracy is to test a number of times. However, due to the time relationship, there may still be missed or not accurate enough, please bear with the reader, after reading the welcome message to discuss the exchange, do not come to the spray.

Note: feel that the article is too long lazy series can be pulled directly to the end to see the summary table.

1 Comparison of basic shape and performance parameters

Before the review began, I collected the main performance parameters of the four machines and created this small table, from the list you can see the technical characteristics and highlights of each machine, to help readers first establish a more accurate product concept.

The four machines that took part in this test were interesting. The chase and cloud whale used the trapezoidal body shape handed down from the old ancestors (Neato XV-11), while the stone and Coors had the now popular round body shape. From an aesthetic point of view, I really don't see any difference, everyone's designers are working very hard.

The difference in the shape of the bottom of the body is even greater, you can clearly see the different schemes of each, the most obvious is that the Cloud Whale J2 uses a double mop front design, and is the only machine that requires manual replacement of modules for mopping and sweeping (which is a minus in use), while the other three use a mop rear scheme.

Replace the angle can be seen more clearly, stone, Coors, chase for the three machines in the bottom sensor configuration is almost the same, are 6 cliff + carpet sensor, while the upper left corner of the cloud whale is much worse, it only has 4 cliff sensor at the bottom, no carpet sensor, considering that the price of this goods even more expensive than the chase for some, which is a bit unjustified.

These four machines are also representative of the main roller brush, the common types of roller brush on the market are all covered. Chase for the use of brushes and rubber scraping interval installation of the V-shaped, Coors is also this program, but increased the number of rubber scraping blade, the stone is the only pure rubber roller brush design currently on the market, the strongest resistance to hair tangling ability. As for the cloud whale, this really does not ......

The four machines also differed greatly in their mopping cloths, with the exception of Stone, the other three all using round or round-like rotating mopping cloths. The stone is the only constant humidity pressurized mop with a vibration frequency of 3000 times / minute (what a long name), this is the stone technology developed from the T7S series, according to my previous test results (I am a long-time user of T7S and cloud whale J1), in the current wipe machine is the best results, together with its unique mop automatic lifting technology, but also to beat a number of friends (there are detailed (there is a detailed test later).

Next we look at the side brush, the four machines with double-sided brush design is Coors and Cloud Whale, the other two keep the single-sided brush structure, the two designs who is good and bad to date there is no conclusion, I do not deny this.

Stone's side brush also accounts for an originality, it is the only manufacturer that uses screws to fix the side brush, slightly troublesome to replace, but the fixed strength is really the highest, not easy to be stuck off when encountering carpets or crevices.

The side brush looks the most tawdry, it uses 5 bristles design, but its side brush length in 4 machines and is the shortest, said to be effective in reducing the probability of playing flying trash, the actual performance of how we will do a specific test later.

Cloud whale's side brush, well, pretty good looking ......

Coors X1 OMNI and stone G10S Pro are equipped with built-in water tank, which Coors is not removable, stone can be manually removed, both support the base station automatic water refill function. The benefits of this are also obvious, making the mop humidity in the work to maintain the best, the ground water damage is very uniform, and the number of backwash is minimal.

LDS LIDAR located on the top of the body, which is the first generation of intelligent planning sweeper since the birth of the popular technology, the four products in this review as the manufacturer's top production, naturally can not be less. Objectively, the difference between them is actually very small, the only difference is made by Coors, which uses a piece of infrared-transparent plastic material to protect the LDS radar, more advantageous than several other in terms of dust.

The next introduction of the front navigation sensor, is the most technically different part of the sweeping robot, different manufacturers have a variety of programs. Above is the front part of the stone G10S Pro, you can see that the goods have been developed to a very complex degree, in addition to the top LDS (triangle / dToF) navigation distance measurement, front structured light + camera obstacle avoidance configuration allows the stone can identify a variety of obstacle types, and corresponding to take different obstacle avoidance strategy.

Since the G10S Pro tested here is also the top of the line from Stone, it also has a LED white fill light in the front sensor area, which is because it has video cruise, obstacle photos, and other functions that require vision in dim environments.

Finally, because the Stone G10S Pro also uses a two-way entry (charging and washing mop need to be head and tail entry), so in the already crowded front induction area also added back to the charging sensor, which a large number of things crowded in such a small place, looks very technological (except for dense phobics).

Coors X1 OMNI as a sweeper giant engine comparable to the stone, although the appearance does not look as blustery as the stone, in terms of the front sensor is not too far behind, it also has the same structured light + video recognition navigation technology, which can achieve such functions as obstacle species recognition.

Chasing the W10 Pro as the current in-house flagship, the front navigation hardware looks a little simpler, but it's still hybrid navigation. In terms of technology, it uses a dToF depth of field sensor + video recognition navigation solution, which is very similar to the Apple FaceID solution that Apple started using on the iPhone X. The presence of a monocular camera makes chase also have some obstacle type recognition capabilities as well.

Finally, this is our poor Cloud Whale J2, perhaps because it was the earliest on the market, or the product manager's confidence in his own navigation algorithm, it has only one infrared proximity sensor installed in the front of the body, which is the sensor along the edge in the other three models. This sensor can only provide the basic distance detection function, and will fail when encountering complex structures, as for obstacle recognition, don't even think about it, J2 as the current flagship model of the Cloud Whale family, this configuration is indeed too shabby, I hope to launch J3 soon.

We just mentioned sensors along the edge, so let's take a closer look. As the name implies, the edge sensor is a sensor used to keep the wall distance when sweeping along the edge of the sweeper. As the top model, it is naturally all equipped. Surprisingly, the cloud whale, which has been pulling across, unexpectedly set up 2 edge sensors on one side of the body, while the other three models are coincidentally placed only one. Is the cloud whale along the edge of the technology more advanced, or the algorithm can not be the number of together? Let's explore this issue later in the test.

Summary: performance parameters comparison link, stone with more and richer sensors than rivals, full floating pure rubber main brush and removable built-in water tank came out on top, Coors and chase after the second, the cloud whale bottom.

2 Comparison of base station functions

From the frontal appearance, the four machines of the base station outline formed a clear 1:3 posture, they are not very different in width, but the difference in height is obvious, Coors base station up to 48CM, while the cloud whale and chase the height of about 43cm, the shortest is the stone G10S PRO, it is only 42cm high.

From the direction of the thickness of the body, the thickest machine is the Stone G10S Pro, the whole 50cm, while the Cloud Whale J2 gets the slimmest award, only 36cm.

From the perspective of space-saving and easy to place, the smaller the size of the base station, of course, the better. The stone takes up the most floor space, but it also has the longest ramp plate, which facilitates the machine to be able to better back-fill/backwash without slipping, so this is both an advantage and a disadvantage, depending on how you define it. In addition, from a functional and practical point of view, the larger base station can accommodate a larger water tank and dust collection box, seems to be an advantage again, ah, selection anxiety I seem to scratch my head a little.

Fortunately, with the advancement of technology, there is finally the ultimate answer to this question, and that is ...... Automatic water up and down. With this function, the volume of the water tank becomes completely meaningless. And in the four base stations we tested, the current cloud whale J2 has been able to directly purchase water up and down components to achieve this function, the stone G10S Pro also designed this component as an extension of the base station accessories, the promise will soon be on sale. And Coors X1 OMNI and chase for W10 PRO currently does not seem to have news in this regard, I hope they will introduce this feature in the next generation of flagship it.

Since we are talking about the water tank, it is better to take a look at it. In the picture above, you can clearly see that the Stone's water tank is the smallest. You should know that this is not a concession made by Stone's engineers to reduce the size, but because Stone uses the most water-efficient mopping solution of the four machines so far (of course, it is still installed with water and water components to be cool).

In order to avoid the tank of stored water breeding bacteria and viruses, manufacturers have introduced a sterilization function in their products, stone, chase foraging and Coors are coincidentally the use of slow-release silver ion sterilization technology.

The cloud whale, it is very unique to get a germicidal liquid automatic addition system, so that a bottle can last for 50 days, which is also a solution to the problem of bacteria breeding.

Stone's 2.5L dust collection bag

Coors' 2.5L dust collection bag

Stone and Coors coincidentally use a dust collection bag with a capacity of 2.5 liters, which can theoretically achieve a frequency of use of 60 days a throw. The dust collection bag itself is made of non-woven fabric, with a movable sliding door design that does not leak ash when removed. From the actual product looks, stone plastic pull ring workmanship and strength than the Coors paper pull ring better, but Coors all-paper material and more environmentally friendly, who better of the two will have to judge for themselves.

Coors, chase for and cloud whale these three sweepers with rotary floor wipe program, their base station also looks very small difference, are fancy squeegee cleaning mop structure, base station on both sides are also installed with guide rollers to facilitate the entry of the host. One of the slight differences or Coors base station, because of the dust collection function, so it has an additional internal vacuum port, I tested this machine seems to have a little dust leakage, the base station inside a little dirty.

Stone G10S Pro base station must be taken out separately, which is the cleanest base station solution for this test cleaning mop (those three are mop to rub the base station, stone is the cleaning brush and scraper in the base station actively to rub the mop). Because the cleaning ability of the brush far exceeds the injection scraper, so the base station is very clean inside, and compared to the Coors, there is no dust collection and leakage of ash phenomenon.

I appreciate this design from my personal preference, reasonable and technological. But it also has the disadvantage that the structure is more complex and slightly more expensive.

Finally, look at the rear of the four base stations, you can see that the stone and Coors design has a power cord storage slot, while the other two are not, this is the difference between the head of the company and ordinary enterprises, the difference in product details is still quite large.

Summary: base station function comparison link, stone with dust collection device and self-cleaning base station ahead of several other models, Coors second (with dust collection without base station self-cleaning), chase for and cloud whale bottom.

3 Navigation and obstacle avoidance ability test

As a representative smart device in the home, the sweeping robot, access to the network and other things are among the most basic operations. The four machines to add WIFI are also very smooth, including the stone and chase for as a member of the Mijia ecology, can be added directly into the Mijia APP, while the cloud whale and Coors has its own APP system (stone also has a separate APP, but in order to be linked with other Mijia devices, generally do not use).

This house has a living area of 90 square meters, and here are the results given after accessing WIFI, from the start of the build to the completion of the first whole house sweep and mop, in order of the fastest time from left to right.

First place went to the Stone G10S Pro, which took 68 minutes and cleaned 56 square meters.

Second place went to the W10 PRO, which took 76 minutes and cleaned 64 square meters.

Third place went to the Cloud Whale J2, which took a full 164 minutes and 15 seconds to clean 109.63 square meters.

Fourth place for Coors (did not expect it!) It took 25 minutes to clean only 15 square meters!

Why is there such a huge achievement gap in the same set of houses? This is the most core algorithm problem of each house. The real cleaning area of my house is the closest to the 56 square meters measured by Stone (57.2 square meters converted by removing the space occupied by furniture). Cloud whale and Coors measured the area of large errors. The reason for this, I think it is because of the counting error caused by wheel slippage when turning the door over. And Coors this 15 square meters of results will have to be singled out to talk about.

First of all, let me show you a motion picture, this is the Coors after cleaning the first bathroom, encountered the first can not climb up the motion picture. The height of this can is 2cm, and also deliberately installed a plastic ramp. The other three sweepers came up without difficulty, while the Coors could not pass. After several attempts, I think this may be a small bug in the Coors algorithm, that is, its carpet sensor will be misjudged, it is this plastic material ramp as a carpet, so the start of the avoidance mode (rotary wipe the pot, the stone because it will lift the mop, so no need to avoid the carpet). After a dozen attempts, the Coors X1 finally climbed up, but probably because it thought the whole room was carpet, so it terminated the sweeping process, which is why it ended up sweeping only a mere 15 square meters to end the task normally (I also hope that Coors engineers can answer this question if they are lucky enough to see me in this article).

This is the chase for W10 Pro's obstacle avoidance ability test, to participate in the test of obstacles players I chose Coke, slippers and data line, these are common items on the ground at home. As you can see from the motion picture, the obstacle avoidance algorithm is very good, although there is an occasional collision throughout, but the strength is not too big, obstacle avoidance performance is relatively stable.

This is the final cleaning path generated by the chase. You can see that the ground in the boxed area is effectively cleaned, and the slippers placed in the middle of the obstacle are also successfully identified, although the data line and Coke are not identified.

Stone G10S Pro, it also successfully completed the obstacle avoidance test, and the test during the touch of obstacles is the least, especially worth mentioning is that during the stone test, the family's cat master also ran over to make trouble, but ultimately did not have any impact on the cleaning of the stone.

As you can see from the map at the end of the sweep, the Stone G10S Pro's obstacle avoidance is more accurate than the chase. It not only recognized the shoes, but also recognized the data line placed on the ground and took a picture of it.

The third player is the Coors X1, in general it also completed the obstacle avoidance test and smoothly cleaned the ground, but the whole process of obstacle avoidance is slightly rougher than the stone and chasing for. All of the test obstacles were touched or pushed away, and even a bottle of Coke was knocked to the ground. This result is frankly a bit surprising to me, in terms of navigation configuration, it is slightly weaker than the stone G10S Pro, but still much stronger than the chase, this result is beyond my expectation.

From the end of the cleaning navigation map can be seen, although the Coors has a camera to identify obstacles, but it does not identify the obstacles displayed on the map, although the cleaning route can be, but these details are still slightly inferior.

The last to appear was the Cloud Whale J2, and frankly I had little hope for it due to its low configuration of navigation devices. The results of the test were no surprise, for these light in size and clutteredly placed obstacles. The cloud whale J2's collision detection plate is almost useless, and its entire cleaning process is like a bulldozer, pushing all the obstacles away.

The navigation chart after the completion of the cleaning looks optimistic, the planning box of the cleaning achievement is all covered, well, things are pushed away, naturally can be full coverage of it.

Cloud whale J2 also has a most deadly bug, that is, the above picture in this computer chair, this goods every time cleaning to this kind of chair will be stuck, in my test it a few days, this goods were stuck several times, so that later I did not dare to let it into the study.

Summary: The navigation algorithm is like the brain of the sweeper, as a sweeper person, I always think that a machine is excellent this piece occupies the absolute weight. This is also a real test of the level of each sweeper. In this segment, the stone with the smallest number of collisions and the most obstacle recognition ability, ranked first. I did not expect that the hardware configuration is better than the pursuit of the Coors, this link also turned out to be. It shows that even if the hardware stack is good, without good algorithm support, it will eventually lose. Of course, all aspects are not superior to the cloud whale "bulldozer" again at the bottom.

4 Cleaning and endurance test

When it comes to battery life, you have to look at the built-in batteries of these four machines. Among them, the stone, Coors and cloud whale are used to be called the standard intelligent sweeper 5200mAH lithium battery, the difference between the three is just different packaging, from the appearance of the stone package is the most standardized, Coors and cloud whale or the old generation of appliances like to use the heat shrink film, but compared to the cloud whale Coors battery is still much more regular.

The battery not only has a nominal capacity of 6400mAH, but also uses a very unique split design, with four cylindrical lithium batteries packaged on each side of the body. Although the capacity is the largest, but in the actual cleaning session (running map capacity) chase for efficiency is slightly lower than the stone, the large battery is also considered a comeback.

For the test of cleaning ability, still from the pursuit of W10 Pro, the test project is very simple, but for the sweeper and very cruel, the combination of soy sauce + cat food particles for the general model is very difficult to clean, so far can be perfect once the machine, only a brand of scrubber products (but that is manual).

As you can see from the picture above, the cleaning ability of the chase is quite good, the cat food is missing (3 grains) but not much, there is a small amount of soy sauce residue on the mopped floor, although not completely clean but still an acceptable category.

The cleaning ability of the stone is a little stronger than the chase for some, first of all, all the cat food was swept away, 5100Pa suction power is really extraordinary. Secondly, its mopping effect is also slightly better than that of the chase, although there are still omissions when you look closely, but it is already very slight (after the test is completed, cleaning the battlefield is also let the stone finish).

The test to the Coors, I did not expect as the king of the machine, it actually turned over again. I do not know if it is the pot of bilateral brushes, Coors X1 on the cat food fight fly very powerful, as you can see from the above picture, after the end of cleaning, almost half of the cat food was left out on the ground. The cleaning of soy sauce stains is also not very satisfactory, the amount of residue is even greater than the chase foraging, the ground is directly spent, which should not be the flagship level of achievement ah.

The last to appear, naturally, is our bottom little prince cloud whale J2 it. Considering that it is only 2500Pa, but also does not have the ability to vacuum with a roller brush, cat food such a big killer do not make it difficult, let's directly measure its best wipe the floor function.

Test results well, or pull across. In its best wiping ability of the project, the cloud whale J2 and Coors cleaning ability looks similar, belong to the "obvious residue" of this level. Hey, cloud whale you really need to work hard, as the first domestic sweeping machine equipped with automatic cleaning mop, your old business are surpassed by so many people.

After the cleaning test, all four sweepers returned to the base station for mopping. The cleaning effect is shown in the picture above. Cleaning mopping cloth this link, has been the bottom of the cloud whale J2 finally pulled back a point, it is not easy. Stone and chase foraging second, the naked eye can see a little residual dirt, but can be considered completely clean level. And Coors, you above this small pile of yellow stains, can only leave the last place to you.

Summary: In terms of cleaning solid and liquid waste, Stone once again ranked first, chasing for a slight disadvantage in the second, Coors and Cloud Whale tied at the bottom. In terms of battery life, the 6400mAH battery is the largest, the stone cleaning efficiency is the highest, the two combined tied for first. Mopping cleanliness cloud whale first, stone and foraging for a slight disadvantage tied for second, Coors at the bottom.

5 APP experience

When writing this test project, frankly speaking, there is still a bit of resistance inside, with the sweeper friends actually probably understand, in terms of APP ability, stone and Coors is in the absolute crush that group exists, let chase for and cloud whale to compare this project, it can be said that the results are obvious.

To corroborate the above conclusion is very simple, this is the test machine to hand, the first connection APP upgrade records, stone and Coors engineers for upgrading the firmware is still very diligent. As for the pursuit and cloud whale well, these machines to my home for two weeks, have not seen the upgrade prompt is what kind of.

Both Coors and Stone's maps support 3D rotation, and Coors' 3D looks a little cooler. But after all, Stone's R&D strength is also not bad, although the map is not cool enough, but its intelligent recognition function is much stronger than Coors, which can autonomously identify the room type, ground type, and indoor furniture. Like the above set of houses, the stone is completely correct in naming the rooms after successful independent map building, accurately judging the ground material is tile or flooring, and its recognition of indoor furniture is accurate to about 60%.

The map supports automatic room differentiation, but it is limited to that. The map of Cloudwhale is simply the level of the first generation of products, rough wireframes make people suspect that its artists are amateurs.

Enter the settings interface of the sweeper, in addition to the traditional various suction settings, wipe frequency, the stone G10S Pro system settings can be said to be dazzling, it can be said that the four machines set the most features, but also the most detailed, and even whether there are pets at home, the body light these small details can be set independently.

The remaining three machines can also do some unique settings in the app, but they don't add up to as many as the Stone family, so to save readers' time, a combo chart carries over.

Summary: The 3D rotating map of Coors on this link is a bit more beautiful, while the stone APP has the most features (also supports 3D rotation), chasing for and cloud whale APP has no special highlights.

6 Features and expandable features competition

This review of the four sweeping robot companies, they can survive today, in addition to the machine itself does a very good job in addition to the function, each family has some unique masterpiece, it is the existence of these small features, so that the industry is not so dull.

1 Features of Stone G10S Pro

Along the edge of the sweeping speed control function, stone G10S in the host is judged to be along the edge of the sweeping, will actively increase the speed of the side brush to enhance the cleaning effect, because the body close to the wall, no need to worry about the side brush hit the problem of flying garbage.

Intelligent fill light function, stone G10S Pro in the dim environment work, will intelligently turn on the white fill light, you know this light is not prepared for navigation, but for better identification of obstacle avoidance, and can take a clearer picture of obstacles, so this feature is not only other manufacturers do not have, even stone's own ordinary version of the G10S is not.

Intelligent mop lifting technology, this is an old technology of Stone Technology, since the T7S series appeared in the stone sweeper, so far, it is still the stone's unique masterpiece. With the mop lift, the treatment of carpets from avoiding to go to casual wear (transformed suction mode cleaning carpets), and after the host back to the station, you can also lift the mop to avoid bacteria breeding.

2 Coors X1 OMNI features

In X1, the top flagship of Coors, I think it is the most unique is the AI voice assistant named YIKO, the goods are not a simple voice control robot, but similar to Xiao Ai classmates intelligent AI. therefore, through the YIKO not only can achieve natural voice control, but also can achieve many other command functions, such as asking a weather, calculate a math problem or something, and then continue to The development continues, there may be external matters ask Baidu, internal matters ask YIKO scene.

Working in conjunction with YIKO are these three full-range microphones located on the overhead LDS. Coors X1 through it, you can achieve the positioning of the user tracking function, but also because of this function, Coors X1 OMNI in the first sweeper class to achieve the "call cleaning" function, this function is very interesting, when you need to temporarily sweep the local ground, just stand in the location to be cleaned, call YIKO to sweep.

3 chase the W10 PRO features

In this cross-evaluation of four machines, the view of the W10 Pro from the beginning of the more contemptuous, slowly become "Oh, not bad" attitude, the main reason is because this machine in the navigation, cleaning and other aspects of performance are very balanced, stable. It can faithfully complete their established cleaning tasks, but also has in addition to automatic dust collection, such as mopping hot air drying such as the top models only have the function.

Therefore, I think the most important feature of chase is two words "stable", if you need to add two more, it is "cheap".

4 Features of Cloud Whale

In the body of the Cloud Whale sweeper, I honestly only found such a unique feature. With this switch, the Cloud Whale is able to turn off the body's cliff sensor and instead rely on its strength to cross the barrier, which is a boon to families with a relatively high threshold. However, this feature is also considered a double-edged sword, after opening the machine will lose security, if there is a very high drop in the home when the structure (such as stairs), it may cause the sweeper to fall.

IV Summary

If you want to choose a sweeper ceiling or the existence of the king of the four machines in this cross-evaluation, it is undoubtedly the stone G10S Pro. As the flagship model with the latest listing, powerful functions and the largest upgrade space, this machine with its 5 + 2 superb features, mature and stable navigation devices and algorithms, cleaning power outstanding sonic vibration mop, automatic cleaning base station technology, the Comprehensive APP function module ...... It can be said that "what others don't have it has, what others have it is stronger".

If you have enough budget, you can't go wrong by choosing it with your eyes closed. If the budget is not so much, you can consider its younger brother, the Stone G10S, the price is much lower, and the features are basically the same in the rest of the common core functions, in addition to the automatic identification of markers and take pictures, and video call function.

Of course, in addition to the king, chase for W10 Pro performance is also quite good, as the lowest priced of the four machines, it is more stable navigation algorithm, good cleaning effect and Mijia platform to bring the whole house IOT controllable features have impressed me, relatively small body size makes it more advantageous when cleaning narrow environments. Although the overall performance is not as good as the stone, but basically every test is not bad, in addition to no automatic dust collection, no self-cleaning base station and no optional automatic water and sewage function, there are no obvious shortcomings or bugs, for users with insufficient budget is not a very good choice.

Coors X1 OMNI as the end of last year, a king bomb level products, overall can only be considered average, ranked third mainly because of its high price, the performance is not stable enough, and no automatic water up and down upgrade defects also affect the future development of this machine may. If manufacturers can solve small bugs such as carpet detector false alarms, algorithms are more excellent, Coors X1 OMNI can still be called an excellent sweeping robot.
