Cleaning Pattern
Dirt Dog is a robot that cleans differently than the way most people clean
their floors. Dirt Dog uses iRobot’s AWARE™ Robot Intelligence System to
determine the best way to pass over and clean every section of the floor.
Dirt Dog calculates the optimal cleaning path as it cleans and determines
when to use its various cleaning behaviors:
Spiraling: Dirt Dog uses
a spiral motion to clean a
concentrated area.
Wall Following: Dirt Dog
uses this technique to clean
the full perimeter of the
room and navigate around
furniture and obstacles.
Room Crossing: Dirt Dog
criss-crosses the room
to ensure full cleaning
coverage.
TIP: Dirt Dog takes approximately  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 Dirt Dog to one room.
TIP: Wires should be elevated off of the floor and rug tassles should be tucked
under the rug to prevent Dirt Dog from getting stuck.
