It took me a long time to decide on a purchase. It was confusing that Xiaomi with the same functions costs 2 times cheaper . My colleagues have all irobots that have been serving them for 5.8 and 9 years. just changed the brushes. That's why I chose this company. When choosing equipment, I choose models that are simpler, but reliable. someone, on the contrary, loves it more twisted . but in the same xiaomi, the card often crashes and the applications are buggy (there was a camera for observing animals at home, it was buggy stably once every 3 days) It cleans carpets amazingly, even though we only have a rug in the bathroom, now Iβm thinking of laying more, because the robot cleans wonderfully. annoying noise. but since dogs don't bark at it, I turn it on in the morning when I leave for work. in the first week, I followed him and watched how he collects)) friends said that everyone does this at first. chairs go around normally. and even between the legs passes. it is clear that he understands that this is the leg of a chair or table, because he immediately drives around it. even climbed behind a bicycle that stood against the wall. I have been using it for a month and a half - there were flaws that it takes 20 minutes to clean up and go to the station (notification on the phone). I just started it again (right on the phone). I found an instruction on the Internet on how to set up a command for Siri on an iPhone - "Hi siri, launch irobot" I taught myself to put extra chairs on the sofa before going out and throw things from the floor. Dog bowl (ceramic bowl 900 ml) with water does not spill! tapping her gently. if the dogs scatter their toys, just push them. taking into account points in restore, it came out approx. 15,600. took off a star for noise, honestly hoped it would be quieter, but this is my first robot vacuum cleaner.
