In general, I like the product, although there are other principles of washers, for example, Bist Win A100 with a progressively moving napkin. I note that any window cleaners wash mediocrely, without rubbing greasy stains the first time, but if dried dirt is only with a rag. Some pros: 1. Napkin with almost rectangular corners (greater capture of space in the corners of the surface) 2. New type of sensors (vacuum) - more sensitive than previous models 3. A pair of ultrasonic sprayers - allows you to apply more liquid to the surface 4. Rich equipment - two additional atomizers, 3 Napkins, detergent bottle Cons below: 1. With abundant wetting of the surface, caterpillars slip 2. Leaves a lot of streaks on a cold surface 3. When falling, the atomizers are immediately damaged, you need to change 4. Slow cleaning of the surface, wipes must be changed after each wire.
