 iRobot Roomba 500 Series www.irobot.com 
Cleaning System
Roomba features a patented 3-stage cleaning system.
Floor Surfaces
Roomba works on wood, carpet, tile, vinyl and linoleum, and will automatically
adjust to different floor types.
Cleaning Modes
Roomba will clean based on the cleaning mode you select. Roomba has three
cleaning modes.
Clean Mode (all models)
Roomba automatically calculates the room size and adjusts its cleaning time
appropriately.
Spot Mode (all models)
Roomba will spiral approximately 3 feet in diameter and then spiral back to
where it started, intensely cleaning a localized area.
Scheduled Cleaning Mode
(Models 550 and above)
When a cleaning time is programmed, Roomba enters scheduled cleaning
mode. When Roomba is scheduled to clean, it will occasionally flash its next
scheduled cleaning time to indicate it is scheduled. At the specified time,
Roobma leaves its Home Base, cleans, and then returns to the Home Base to
recharge when its done.
