I received this robot-scrubber there is a month without bp; I could test in Lorraine, and in Roussillon, on tiles: He washes in a way that you might think by looking at random to, but by putting it in place and returning once it has stopped, the dominant impression is that of cleanliness; at first, there are traces, certainly, but as and washes, the result is visibly improving. it only takes minutes to prepare qq: pour a capful and water in the tank; it is placed in the middle of the room trying there the least possible obstacles (otherwise it turns around), it is put on and ... we'll do something else! a biking morning or ironing, or dishes (yes! I have no dishwasher, but I have a cleaning robot!) or some gardening ... When he finished, usually is that it has no clean water, it stops; we must go and look; it does not return alone to the base; anyway, connect manually to recharge; it is not programmable either, unlike his friend the robot vacuum cleaner, which itself deserves its 5 stars because of this difference. Then we did a little cleaning under the tap, in 5 minutes: empty and rinse the dirty water tank, drain and flush the small filter, rinse the small pipe, unclip the set of brushes and squeegees and run them under water, reassemble everything, a small cloth shot on and under the unit before going reconnect, ready for the next use. test in Lorraine: the tile is wet enough in the end, but it was a small area, and it would have been enough that I put less water I think; test in the Roussillon in the end, perfectly dry surfaces, but of greater dimensions; no need to vacuum before: it picks up dust (no chunks!) and dirt that is found in its filter, and lava. It is relatively noisy, it is better to find care elsewhere when it works! He remained in the Roussillon, and I have already made many envious with this funny machine! the robotic vacuum cleaner will stay him in Lorraine where he works wonders on the carpet!
