Review on Viomi Vacuum Cleaner Alpha S9 robot vacuum cleaner, black by Czesawa ledziewska ᠌

To start wet cleaning, I had to pump the pump manually, disassemble the container and pour water into the hoses with a syringe, connected 5v (black - minus, white - plus) to the pump through the power supply. Otherwise, the air bubble could not be expelled from the pump. But this, in my opinion, is the problem of all xiaomi robots. Before that there was a Lydsto R1 with the same problem. But he worked for 10 days and the charging system died in him. Bought this one for almost twice the price. And comparing the two devices, the main difference between them is only the quality of the outer plastic. Everything else is the same, including the quality of cleaning, and this one has slightly better functionality. And outwardly they are one to one. Also lydsto if there is no water in the tank gave a warning and stopped, but this one is silent and rubs with a dry rag. The base swears in German, which introduces into the nervous laughter of the family, the language cannot be changed on it. I would give 3.5 stars for the money. So there is no point in overpaying, take the cheap one! About deleting a card. If the door to the room was closed during the previous cleaning. And this time you want to send a robot there, it will not eat) It will swear that the zone is not available. We bring him to this room with the help of a joystick, and voila, the maps are removed) The problem with navigation gets worse over time. The vacuum cleaner often changes the size of the room, because of this there are gaps in cleaning. The vacuum cleaner is definitely not worth the money.
