2, mopping the floor, this function is relatively general, the level of the whole industry may not have broken through, mainly sweeping the floor, many sweepers with mopping function only strengthen the cleaning effect on the basis of sweeping the floor. It is not recommended to buy it purely for mopping the floor.
3, vacuuming, vacuuming is also the main task, there are sweepers that can only suck, and single suction can only suck tiny things such as dust and hair; There is a kind of sweeper, which can sweep and suck. Considering that it can suck fine garbage and shredded paper, it can certainly sweep and suck well. I recommend iRobot in the United States and zebot in China.
4, sterilization, now many sterilization functions. The main form is that the machine chassis is equipped with a UV ultraviolet sterilization, which can be opened at the same time when sweeping the floor, which can sterilize and remove mites.
5, filter the air, now many brands have the function of filtering the air, mainly through the HEPA filter of the dust box to filter out the dust in the air.
6, negative ion purification, this function is unique, now only a high-end model of zebot developed by Taiwan Province Province, equipped with negative ion generator, in addition to ordinary filtration, can also release oxygen to make the air fresher.
7, voice prompt, this function is becoming more and more common, when the machine fails, it can tell the user what happened, so as to better investigate and solve.
That's about it. Welcome to add.
