After about 20 years of development, the use experience of sweeping and mopping robots has improved significantly, and it has a tendency to become an essential household electrical appliance, and the family penetration rate is increasing year by year. The sweeper has reached the price of 4K and is basically very comprehensive in terms of functionality, and many friends have also set their purchase budget at this price. At this time, the competition for the purchase of a sweeper is no longer a question of whether there is or not, but how to choose the best of the best and do better. Today, through the actual measurement and comparison of three hot-selling models in the market of different brands, Daisheng shares how to buy sweeping and mopping robots, and also takes a look at which one is more worth starting. 
Before starting, attach the parameter tables and brain maps of the three models, so that you can read them on demand:
Functionally speaking, whether the sweeping and mopping is clean or not is the core mission of the sweeping robot. The size of the suction power mainly affects the cleaning effect of stubborn debris hidden in the crevices and large particles; The greater the maximum suction power, the higher the performance redundancy of the machine, which we can not use often, but need it at critical moments. The order of the suction power of the three is as follows: Ecovacs T20S Pro (8000PA) Cloud Whale J4 (7800PA) Dreame S20 Pro (6000PA). 
In the face of large particles of garbage with a certain weight such as nails, Yunjing J4 can be inhaled smoothly. 
The 8000pa large suction power can suck up large particles of garbage such as screws, but there are some slight flying situations, and it takes two more rounds to suck it clean. 
Although the suction power of Dreame is only 6000pa, it performs well and does not fly much. For hair loss stars and shovelers, in addition to sweeping clean, they will also pay extra attention to the problem of hair entanglement. The bristle brush used in the early days was a nightmare! Especially this kind of two ends can not be disassembled, the hair is getting tighter and tighter, and finally it can only be done with a scraper, which is particularly troublesome to clean and maintain. 
Yunjing J4 is the first cyclonic diversion type zero-winding roller brush to solve this problem. 
It is different from the traditional double-arm roller brush of competitors
J4 adopts a micro-cone structure design with one large end and one small end, which is fixed on one side, and the bristles on the roller brush are inclined at 50° to ensure the cleaning power, while ensuring the cleaning power, the hair on the roller brush is more likely to fall off to the small end and be sucked into the dust box or dust bag. 
In the actual test, it can also be seen that the cyclonic guide roller brush can cope with a large number of hairs and easily enter the bag.
All three models use the rotary mopping method, but the difference is that Ecovacs and Dreame mops are both circular in shape.
The cloud whale J4 continues the classic Lelo triangle mop design of the cloud whale, the advantage of this design is to increase the 10mm overlapping area, even if the mop shrinks for a long time, there will be no gaps.
In addition to the shape of the mop, it also depends on the speed and downforce of the mop, if the sweeping robot does not have enough downforce when mopping, then whether it is rotating or vibrating, it is useless work, especially in the face of stubborn stains, downforce is more important. Most of the models on the market use the passive type that presses the mop on the ground by the weight of the machine, and all three models invariably adopt an active design that can actively and continuously press downward. The mopping speed of the three sweepers is 180 rpm. Drying soy sauce simulates stubborn stains
The Dreame S20 Pro has a maximum downforce of 5N, and there will still be some residue in the face of stubborn soy sauce stains, mopping the floor 2 times.
Ecovacs T20S Pro has a maximum downforce of 6N, which is a bit larger than that of Dreame, although there is more residue in the first time, but it can be dragged clean the second time.
Cloud Whale J4The mopping pressure has reached the industry's top level of 7-12N dynamic pressurized mopping, with 180 rpm high-speed rotation, simulating manual mopping, mopping clean is the core selling point of Cloud Whale has always been, J4 is also undoubtedly continued, in the comparative evaluation of stubborn stains, Cloud Whale J4 performance is also the best.
The last test of mopping the floor has come to the corner that has attracted the most attention. In the first two years, there was a problem with the sweepers on the market, that is, due to the arrangement of the fuselage mop, there were more or less dead ends when cleaning along the edge.
The three models tested in this article are all used to "twist the butt" as close to the edge as possible to reduce the cleaning dead space.
Both Dreame and Cloud Whale can be adjusted to be executed daily, while Ecovacs T20S Pro takes 7 days to trigger once, and it would be better if it could be triggered more often.
If the hardware configuration is the foundation, then the algorithm is the brain, and it depends on it whether the robot is smart or not. If the parameters are rolled again, the brain is not good, and it is also in vain. The most intuitive thing is to look at its cleaning path, whether there is a lost picture, a wrong picture, a missed sweep, a detour, a lost way, etc.
Cloud Whale and Ecovacs use a 3D structured light obstacle avoidance scheme, while Dreame uses a dual-line laser obstacle avoidance scheme.
All of them are autopilot-level obstacle avoidance, and it can be seen through actual measurements that they can well cope with more complex home environments, and there is basically no need for manual intervention.
The main function of this function is to intelligently identify home scenes, automatically identify dirt, and intelligently configure cleaning parameters, so as to achieve the whole process without manual intervention, one-click start without complex parameter settings, and improve cleaning efficiency and cleaning effect. The first to realize this function was the "Whale Spirit Hosting" model created by Cloud Whale J3 launched in 22.
Say goodbye to complex operations and settings, you don't need to consider and entangle how many times you should set up sweeping and mopping, you only need to turn on the whale spirit hosting mode with one click, and the robot will intelligently adjust the mop cleaning time according to the degree of dirtiness of the mop washing sewage to ensure the cleanliness of the mop when it leaves the station.
And determine whether to repeat the drag back a second time, and the unclean floor will be cleaned until it is clean.
Later, many brands also followed up one after another, such as the "intelligent hosting" of Dreame S20 Pro and the "worry-free mode" of Ecovacs T20S Pro.
Of course, the cloud whale is not satisfied with this, and J4 is equipped with a newly upgraded "Whale Spirit Hosting 2."0", based on the big data of millions of families in China, the setting is more accurate and the details are full. For example, the air humidity data can be obtained through the network, and the ground material (floor, tile, pebble) can be set, so as to automatically adjust the humidity of the mop; According to the name of the house or the identification of the dirt sensor, for the kitchen balcony heavy pollution room to improve the suction and humidity, the use of well-shaped overlapping fine sweeping.
And in different cleaning modes, the user-friendly logic is set. For example, in the single-sweep mode, the mop module will be lifted to prevent dust from sticking to the mop and affecting the cleaning effect.
In the single-drag mode, the roller brush is raised, and the side brush stops and retracts backwards to avoid the middle roller brush from absorbing water stains and wet garbage, which affects the fan.
The robot will lift all modules during the process of going back and forth between the base station and the cleaning area, and will only put down the corresponding cleaning modules when it goes to the designated cleaning area, avoiding cross-contamination between the modules and the ground on the road.
For the use of carpets at home, all three models are equipped with ultrasonic ground sensors to automatically identify carpet areas;
The three models provide 2-4 cleaning modes respectively (Dreame S20 Pro: 2 types, Ecovacs T20S Pro: 3 types, Cloud Whale J4: 4 types);
In adaptive mode, the mop will be lifted by 10mm to prevent the carpet from getting wet.
For medium and long wool carpet areas (more than 7mm), the carpet avoidance mode can be adopted, which will automatically bypass the carpet area to avoid winding roller brushes, side brushes or wetting the carpet. For the home mat, you can choose to ignore the mode and sweep and mop at the same time;
The spanning mode is recommended to set up a medium and long wool carpet at the door or across the room, which can only be crossed through without cleaning. The selling point of "all-round base station" is not worth taking out separately this year, after all, basically all brands are standard, and the actual details to be compared here are different, and what is the experience in actual use. Models with good maintenance-free performance can greatly reduce the workload of daily maintenance and improve the use experience in daily use, which is still very necessary for lazy people who hope that the sweeper will free their hands. All three models support the optional automatic water loading and unloading module,**Sort from low to high:Cloud Whale J4 (500 yuan) Ecovacs T20S Pro (549 yuan) Dreame S20 Pro (699 yuan), if conditions permit, the first water and water supply kit is recommended, and you can free your hands in one step. If you can only choose the tank version, the size of the water tank is more important, and the large tank can reduce the frequency of water changes under the same cleaning conditions.
In the cleaning and maintenance of the base station,Cloud whaleJ4It has also been upgraded,The entire chassis cleaning rib can be taken out and cleaned and then put back,Very convenient and easy。 The Ecovacs chassis cannot be taken out, and although Dreame can be taken out, there are still stains inside the base station that need to be manually cleaned separately.
Ecovacs T20S Pro and Dreame S20 Pro are designed to store garbage in the base station, and the garbage in the dust bin will be transferred to the dust bag after each sweeper.
Compared with the traditional base station dust collection,Cloud whaleJ4It adopts a new fuselage light dust collection scheme,The dust collection bag with integrated filter is built into the position of the original dust collection box,1L After the dust bag is full, it can be thrown directly away,No dust and no dirty hands。
At the same time, the size of the dust box has been greatly increased to 800ml, providing users with two options to choose to use the dust box or dust bag according to their own needs.
And the innovative design of hair compression technology.
Similar to the principle of vacuuming, so as to further use the space, you can replace the dust bag once a month, in order to completely eliminate the problem of mold and insects stored in the dust bag for a long time, the cloud whale is also targeted design. The filter paper is made of anti-allergic mite removal material.
After the robot returns to the base station, it will ventilate the dust box to keep it dry;
In order to avoid the growth of bacteria inside the base station or host, the three models also achieve 999% full-link antibacterial. Use antibacterial materials in the selection of mop, dust bags and filter elements; Cloud Whale is also equipped with a silver ion module as standard (Dreame and Ecovacs are optional);
Sterilizing detergent can be added automatically (Dreame and Ecovacs only support the water and water versions), so as to achieve the full-link antibacterial of mop + ground + water tank + dust bag.
Ecovacs is the first to launch the hot water washing mop function, T20S Pro supports 55 hot water cleaning, and Dreame S20 Pro has increased to 58.
Mopping with hot water makes it easier to dissolve stubborn stains, and the mop will wash cleaner.
Although Yunjing J4 does not support the function of hot water cleaning mop, the base station is equipped with dual-spectrum detection technology to intelligently identify dirty, heavy dirt and heavy wash, and clean and clean. Regarding the control area on the base station, many friends also feel that since the mobile phone app can be controlled, this place is completely dispensable. As a result, the two models of Ecovacs and Dreame also cut this part.
But smart home appliances are not used by everyone, especially if they are given to parents. Cloud whaleJ4It is the only one with a screen among the three models,You can turn on the sweeper whale spirit hosting with one key base station,Or is it more intuitive to operate in this way。
And in order to avoid children and pets at home, a safety child lock is also designed.
The advanced version of "lazy" is "if you can move your mouth, you don't do it". Both Dreame and Ecovacs have integrated voice interaction functions into the host, and after several rounds of iterations, the scope of voice control has become wider and wider.
Cloud Whale supports voice access from third-party devices such as Xiaoai, Siri, and Xiaodu, so as to achieve intelligent voice wake-up.
It also supports device sharing, which is convenient for remote assistance to elders living alone.
Through comparison, it can be seen that the three models are not much different in functionality, and there are no obvious shortcomings, all of which are enough to cope with daily use scenarios, but there are slight differences in the design of details, and we can choose according to our own concerns and usage scenarios.
Cloud whaleJ4 continues the consistent style of the previous work,The appearance and texture are very good,The mopping function is also the existence of the top level in the industry,The newly developed zero-winding roller brush is very attractive to hair loss stars and shovel officers。 Whale Spirit Hosting 20 is equipped to avoid complex parameter settings, maybe this is the real design direction of "lazy", and it is also perfect for parents to use.
Ecovacs T20S Pro is currently the lowest price among the three, and the brand awareness is also higher, so it is more suitable to buy it and give it away.
Dreame S20 ProAPP has a high degree of completion,The degree of freedom of setting is also very high,The parameter configuration is also relatively comprehensive,It is more suitable for young people to use personalized configuration according to their own use environment。
