Cleaning Pattern

Roomba is a robot that cleans differently than the way most people clean

their ﬂoors. Roomba uses its robot intelligence to efﬁciently clean the whole

ﬂoor, under and around furniture and along walls.

Roomba calculates the optimal cleaning path as it cleans and determines

when to use its various cleaning behaviors:

Spiraling: Roomba uses

a spiral motion to clean a

concentrated area.

Wall Following: Roomba

uses this technique to clean

the full perimeter of the

room and navigate around

furniture and obstacles.

Room Crossing: Roomba

criss-crosses the room

to ensure full cleaning

coverage.

Dirt Detection: When

Roomba senses dirt, the

blue Dirt Detect™ light is lit

and Roomba cleans more

intensely in that area.

TIP: Roomba takes approximately 45 minutes to clean an average room and

will pass over the same area of the ﬂoor multiple times to ensure total

ﬂoor coverage.

TIP: For fastest cleaning and best performance, clear your ﬂoor of clutter and

use a Virtual Wall to conﬁne Roomba to one room.

Cleaning Modes: While cleaning, Roomba automatically calculates the room

size and adjusts its cleaning time appropriately.

Spot Mode: Roomba will spiral approximately 3 feet in diameter and then

spiral back to where it started, intensely cleaning a localized area.
