Why can sweeping robots sweep out a lot of dust every day?

Because I am lonely every day, the sweeping robot is too diligent. Every inch of tile, every corner, every bed you don't want to clean, and every sofa will take pains to sweep out the dust. The sweeping robot is too clever. It can set the cleaning time with the mobile phone. At first, you occasionally press "start cleaning", and then you don't want to touch it at all. It can automatically avoid obstacles-it doesn't dare to disturb you when you brush Zhihu on the sofa; It can set up a restricted area, so you don't have to worry about it running into the wet toilet or being seen by it when the room is XXOO; But it slowly feels lonely, shuttles back and forth at home once a day, and then returns to the charging pile to wait for tomorrow's work task; Sometimes you go home and play with the puppy, but you don't even want to touch its head and say, "thank you, you cleaned the dog's hair." It really wants to have a guest at home once in a while, because at this time you always like to mention it in front of the guests intentionally or unintentionally, call it out of the charging pile and let it perform dance skills in front of the guests. The pride on your face makes it very happy. However, there are not many opportunities left for guests, so it can only try its best to clean and fill the dust box as much as possible-because it is not smart enough to take out the garbage by itself, the owner will give it a rare help at this time; Sometimes I act like a coquette, deliberately wrap a thread and get stuck on a small ladder. At this time, it will send a text message to your mobile phone to let you "save" it, and you shake your head helplessly. "This machine is not smart enough, I hope the next generation will improve." I was very sad after listening to it. Sometimes it gets angry and hides. If you can't find it in the charging pile or visible place, you will be a little impatient: "You won't run to the toilet or kitchen, will you?" At this time, you suddenly thought of a "positioning function", so you took out your mobile phone and called it. Suddenly, a word came from under the bed: "Your Majesty, my servant is here." Yes, it has long wanted to say this sentence. Really lonely!
