iRobot Roomba Anatomy 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.
