He is not friendly with floor scales, socks, wires, he constantly chokes on them and squeaks. During the holidays, it is necessary to turn off the battery, since he has it using the ancient Nickel technology. The first time I frankly missed the choice of equipment, moreover, expensive equipment. With its pros. The quality of cleaning in the first months of ownership is high. In an hour and a half I cleaned an apartment of 100 sq. M from four rooms, although it is necessary to catch it at least once and shake out the filter. You can find inexpensive paper filters on Ali. With its cons. Dear native filters. Almost a year later (before the end of the warranty), error 3000 arrived. Repair at the official service center: they changed the lidar, the lidar motor and recommended changing the battery. Less than a year later, the same problem - error 3000.
