Cleaning Modes; Cleaning System - iRobot Roomba Owner's Manual

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 three 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 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.

into the bin.
Floor Surfaces
Roomba works on wood, carpet, tile, vinyl, and linoleum, and adjusts
automatically to different floor types.
Roomba automatically senses stairs and other cliffs. Roomba might
stall when confronting rounded edges and might slide over particularly
slippery surfaces. Extremely dark-colored floors may contribute to
Roomba's cliff sensors working less effectively.
Anti-Tangle system
Roomba won't get stuck on cords, carpet fringe or tassels. When Roomba
senses it has picked up a cord or tassel, it will automatically stop its main
brushes or side brush and try to escape. Roomba may make a clicking
noise when anti-tangle is activated.
