It is necessary to clean and maintain, if only they themselves learned how to do it)) Its pros: Good price. Qualitatively cleans even around the legs of tables / chairs, crawls under furniture with antennae and sweeps out debris from there. There is wet cleaning. The application shows when consumables need to be replaced. The vacuum cleaner says in 2022 what it needs (add water to the tank, wash the nozzle, clean the container). There is manual control, like a typewriter on the remote control. Funny and sometimes convenient. Cons: You cannot select a specific area to clean up. Strange logic of cleaning: removed a piece of the room, left it, went to another, traveled there, then returned, removed another piece, then left again, etc.
