ECOVACS Robotics DEEBOT D63S Robot Vacuum: Capture dust, dirt and debris while you're out running errands with this robotic vacuum cleaner. The smart design enables the unit to move from room to room while avoiding obstacles, automatically adjust cleaning modes to suit soil levels and return back to the docking station when it's finished.
This Robot Vacuum works okay for a small room (like bedroom). But it does not work for a large room like living room. If the space is large, it is very hard for it to find the charging equipment.
BTW, one can not expect it as powerful as the regular vacuum: it can only do some small cleaning jobs.
