Cleaning Pattern
Roomba is a robot that cleans floors 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
crisscrosses the room
to ensure full cleaning
coverage.
Dirt Detection (selected
models): When Roomba
senses dirt, the blue Dirt
Detect™ light is lit and
Roomba cleans more
intensely in that area.
TIP: Roomba takes approximately 25 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 most efcient cleaning, clear your oor of clutter and use a Virtual
Wall to confine Roomba to one room.
