Original title: feedback on the use of the old man: millet sweeping robot is not bad, it's a good thing
Sweeping robot is something that Xiaobian always wants to start with but hesitates to start with. Because every time Xiaobian consults with friends around, everyone's comments on it are mixed: some people say it's very easy to use, but some people say it's useless at all, so it's better to clean it by yourself. Therefore, the purchase plan has been stranded.
In recent years, Xiaobian and her husband often need to go on business due to the nature of their work. Therefore, the family health is basically all dependent on helping to take care of the children, and the old mother who is over the age of 60 years to clean up. But my mother's lumbar spine is not good. If She Stoops to sweep the floor for a little longer, she will feel that her waist is sore and swollen. When she is serious, she will even suffer from "back pain". In 2019, Xiaobian plans to move to a new house. The new house is larger than the original one, so it must be more tired to clean. Therefore, Xiaobian puts the plan of purchasing sweeping robots on the agenda.
Xiaobian told her mother about the purchase plan, but she was opposed by her mother. It cost thousands of yuan. What's the use of that thing? It's still so expensive. Don't waste money. But this time, Xiaobian decided to buy a cost-effective sweeper robot to go home, so as to reduce the burden of mom. So Xiaobian consults with colleagues who have a better understanding of the product field of sweeping robot, and at the same time knows the brands and models they have purchased from friends who have bought the product in detail. Finally, he chooses to start this super popular sweeping robot in Xiaomi tmall flagship store at the price of 1199 yuan on the day of "double 11" in 2019.

On the second day of moving into the new house in December 2019, Xiaobian's mother began to use the sweeping robot while unpacking. Due to the absence of Xiaobian on business trip, they didn't notice to lose the product manual again when unpacking, so the old couple groped at home, but they learned to use it after groping for a while. According to my mother's recollection afterwards, after unpacking the case, the floor sweeper robot has been assembled. When I put it on the ground and press each button on the robot, there is a voice prompt, so it's very easy to start. They just don't know what they use the rest of it. After Xiaobian explained to them at home, they knew that it was the charging base.
Xiaobian found that the charging base of Xiaomi's sweeping robot is simple white, with charging shrapnel in the middle and black filter on the upper front of the body. The whole base looks very delicate. It is understood that there is a charging identification code behind the base filter. After laser scanning, the sweeping robot can find a place to recharge itself accurately. There are multiple rubber anti-skid strips at the bottom of the charging base. After the small braid is placed against the wall, it can effectively prevent skidding.

And this sweeping robot looks like the style of the rice family when it is designed. The appearance adopts a pure white design, which looks simple and generous. The whole is just the shape of a disc, with no redundant design.
Figure: simple key design and key text description on the sweeping robot
The design of the key is also very simple. There are two keys, one is the on / off key / cleaning key, the other is the local cleaning key / recharging key. This is to open the cover on the sweeping robot, with detailed text marks below. As far as I know, many people like to operate on their mobile phones and set up cleaning routes after buying a sweeping robot, so that the sweeping robot can work after going to work, so as to save time and not be noisy. But because my mother can't use smart phones, and can't let my mobile phone download app remote control operation, so regular cleaning, designated cleaning and other functions have not been tried yet.

There is a round bulge on the top of the button of the sweeping robot. This is the LDS laser ranging sensor. According to Xiaobian, at present, vision navigation and laser navigation are commonly used in sweeping robots, or a combination of them. The technology of visual navigation is relatively mature and low-cost, and the route planning is realized by algorithm and big data processing; the laser navigation obtains the environmental information by laser, measures the time from laser sending to receiving, calculates the distance between itself and the obstacles in front, and obtains the environmental model by algorithm processing, and obtains the positioning and walking route in the continuous scanning and ranging. In terms of accuracy, laser navigation will cost a little more, but it is much more accurate. Xiaomi's sweeping robot has an accurate ranging range of about 6m.

Under the side of LDS laser ranging sensor, there is a large area of air outlet, which is proportional to the suction. According to Xiaobian, Xiaomi's sweeping robot adopts Japanese Nidec brush less motor, with wind pressure of about 1800pa and continuous operation life of more than 1500 hours. It can take 1500 days and more than 4 years according to the daily cleaning and one hour cleaning.

Just below the button of the sweeping robot, there is a small bulge on the cover. Xiaobian thinks that this design is very humanized and convenient to open the cover. Inside is a full transparent dust box. The air inlet of the dust box is surrounded by rubber rings, which can effectively prevent dust and secondary pollution. On the dust box, there is a sign of "no washing of filter screen". Xiaobian's house has been used for more than two months. There is a lot of dust on the inner wall of the dust box. Because it can't be washed by water, Xiaobian's mother can only wipe it with a rag every time.

Picture: two main wheels of the universal wheel and the side brush at the bottom of the sweeping robot
At the bottom of the sweeping robot, the structure is relatively complex. You can see that there are many parts. First, there are three wheels, one of which is the universal wheel at the front end, which is mainly used to control the forward direction of the sweeping robot. The two big wheels on both sides of the bottom are the main wheels. There is a certain rebound design, mainly the driving wheels. The sweeping robot can cross some small thresholds and obstacles at home They are.
Illustration: rolling brush
In the middle of the two main wheels, you can see that there is a roller brush and also the main brush of the sweeping robot. This brush can be disassembled and cleaned according to the directions of the two arrows above. In addition to a layer of bristle design, there is also a layer of red silica gel brush on the roller brush, which can have multiple cleaning effects. According to Xiaobian, this structure is also used by most mainstream sweepers at present.
Drawings: edge brush
At the end of the roller brush, next to the main wheel, you can see a triangular brush, which is the side brush of the sweeping robot.
Outside the brush, there are electronic compass sensors, cliff sensors, gyroscopes / accelerometers, odometers, fan speed sensors and other components at the bottom of the sweeping robot.
Practical experience:
Xiaomi sweeping robot is basically managed by my mother at Xiaobian's house. For the convenience of use, she has been using the mode of sweeping the whole house. Just press the "on key" on the sweeping robot. According to my mother, at the beginning of use, the millet sweeping robot will "walk" all corners of the family. For example, when cleaning the living room, first "survey" the general cleaning scope and identify where there are obstacles. After the "survey" is completed, the sweeping robot will plan the sweeping route by itself, basically going to the wall first, and adopting the "Z" shaped sweeping route in the middle to ensure that every place within the sweeping scope is cleaned.

Mom said that her most satisfied place with the robot was under the sofa, under the tea table and TV cabinet, under the bed and other places that were not easy to be cleaned manually before. The robot could "drill" in and clean up. "With a sweeper robot, you don't have to bend over to clean these dead corners anymore." My mother likes to open the window and ventilate. She cleans every day. She can also sweep a lot of dust at home.

And to my mother's surprise at the beginning, this sweeping robot will recharge automatically. My mother said that every time the sweeping robot is charged, the power is enough to clean the house once. And every time after cleaning, no matter where the robot is, it can find its own charging machine and recharge itself, "it's really smart, no wonder it's called a robot."

There are many scars on the robot
However, this millet sweeping robot also has places that make my mother think it "stupid". The tea table and TV cabinet of Xiaobian family have irregular shapes under the drawers. At the lowest point, the sweeping robot just can't pass. Mom said that Xiaomi sweeper robot often "stuck" at the lowest point to "call for help" and needed mom to manually "take" it out. "Every time I do other housework, I don't hear the sound of the sweeper robot, and it's not on the charging stand, it's stuck there in nine out of ten, making it full of scratches." Mom complains, "you say that this sweeping robot is smart, smart, and knows how to sweep the floor. After sweeping, you go back to recharge, but sometimes it's stupid. Once you pass the card, you know whether you can pass here. Next time you don't want to leave here."
