It is used to clean the entire 1200 sq. ft. downstairs tile and hardwood floors. It is used almost daily to spot clean crumbs on carpet around TV recliners. It cleans the almost 1000 sq. ft. carpeted upstairs. It gets under low heavy furniture where we used to never vacuum. Also under beds that also rarely got vacuumed. Spot cleaning zones are designated on the floor maps as well as no go spots. It does a very good job of finding the cleaning zones when sent to clean there and not going into no clean zones. I always move obstacles prior to sending it to vacuum in order to get very thorough cleaning. It is very important to watch for cords and wires to prevent the bot from tangling up and calling for help.
