I want to share my opinion. I read the reviews, chose for a long time what kind of vacuum cleaner to take - this is our first vacuum cleaner. Chose somewhere 4-6 months. I thought it makes no sense to take a cheap one, as they say: a miser pays twice)) . And finally, a miracle happened - I bought it))) . the application from him was already installed, since we have a home camera, so everything turned out cool and easy connect with him! In the application, they asked me to connect to it through Wi-Fi, I had an iPhone, I chose the name that was offered to me and voila! At first, I picked everything up from Paul and launched him, he immediately built a map, and at that time I figured out his settings: I installed the language, connected it to Alice, set up scripts. And I turned on the slider in the application by going into the "map save mode" test! I let him into 2 rooms, he perfectly built a map the first time. I saw how it works, I dropped the card, I thought that I needed a corridor with a kitchen too))) . Then it seemed to be very clogged, since we have a Rottweiler and a cat))) I had to vacuum it with an ordinary vacuum cleaner, because he shouted at me and asked me to wipe the sensors ! Vacuum cleaner just class! I turn it on and go for a walk with the dog, I come, and he cleaned the children's room, the kitchen, the corridor and the large bedroom for me. Persistent, powerful, smart, hard worker! I am adding a photo. I forgot to close it, left a little crack, the door in the living room, there is a thick carpet, so he opened the door himself and went to vacuum the carpet))) I was shocked, quickly paused it and took it out into the corridor. I don’t add the video, since the dust collector speaks for him, in the photo he collected it from the carpet and from other rooms)))
