Cleaning Modes - iRobot Roomba 500 Series Owner's Manual

Cleaning Modes

Roomba will clean based on the cleaning mode you select. Roomba has
three cleaning modes.
(all models)
Roomba automatically calculates the room size and adjusts its cleaning
time appropriately.
(all models)
Roomba will spiral approximately three feet in diameter and then spiral
back to where it started, intensely cleaning a localized area.
(Models 550 and above)
When a future cleaning time is programmed, Roomba enters Scheduled
Cleaning Mode. When scheduled to clean, Roomba will occasionally flash
its next cleaning time to remind you of its schedule. At the specified time,
Roomba leaves its Home Base, cleans, and then returns to the Home
Base to recharge when it's done.
