Viomi's capacious robot vacuum cleaner will become your smartest helper, especially if you own a Multi-Floor house or an additional apartment or country house. It will selflessly clean 5 floors with 2,700 pascal suction power. With the help of a laser, it will quickly scan the entire space and automatically make a cleaning plan. Navigation is facilitated by 12 different types of smart sensors, including anti-collision, anti-drop and anti-wall. It flexibly crawls over an obstacle 2 cm high, even on a carpet. It has a 300 ml dust and 250 ml water tank, in addition, a self-controlled water pump, which prevents liquid leakage. It can suck, pull and work in wet mode at one time. It absorbs dust, hair and liquid stains at the same time. After filling the tank, it will clean itself. The filling of the tank will be notified by the screen and the Mi Home application, in which you can specify the cleaning time, mode, area and not only that, it will not delay cleaning when you want, where you want and how you want.
