My first robot vacuum cleaner. Cleans house 110 sq. M. Dry cleaning - 5, wet - 2. Average score - 3.5. I'll round up to 4, because. I rarely do wet cleaning and overall impressions are 4 more than 3. Got pros: Good and fast vacuuming. No fluffy brushes, no winding, always clean Cons: Wet cleaning. Water comes from one nozzle to the center of the rag, the width of the wet track is five centimeters. You say: "So you need to moisten the rag before cleaning! " I will answer that I wet it, but it dries out after 10-15 sq. M and it needs to be wetted again and so on every 10-15 meters. In the instructions for wet cleaning fiction, it is written that it is advisable to rinse the rag every 60 minutes, in fact every 10 minutes.
