Roomba cleans based on the cleaning mode you select. Roomba has three cleaning modes.
Note: Please note that your robot series may vary. Roomba 400, 500, 600, 700, 800 have the same cleaning modes.
Clean Mode
Just press CLEAN! Roomba automatically calculates the room size and adjusts its cleaning time appropriately.
Spot Mode
Press
SPOT Clean on the robot. Roomba spirals approximately 3 ft ( 1 m ) in diameter and then spirals back to where it started, intensely cleaning a localized area.
Scheduled Cleaning Mode
When a future cleaning time is programmed, Roomba enters this mode. At the specified time, Roomba leaves its Home Base®, cleans and then returns to the Home Base to recharge when it’s done.
