Virtual Walls® (optional accessory)
The iRobot Dirt Dog Virtual Walls create an invisible barrier that Dirt Dog will
not cross. The Virtual Walls can be set to block an area ranging from three to
eight feet long.
TIP: Use the Virtual Walls to block doorways or to keep Dirt Dog away from
cords. Confining Dirt Dog to a single room will accelerate cleaning.
The Virtual Wall beam is keyhole shaped. A small
halo prevents Dirt Dog from bumping into the
Virtual Wall and a larger lobe-shaped section
blocks off areas of your home where you don’t
want Dirt Dog to go.

Battery Installation

The Virtual Wall requires 2 “D” batteries and
automatically shuts off after 135 minutes. If the
power light blinks green, the batteries will soon
need replacement.

Range Adjustment

Use the slider bar to adjust the length of the barrier.
A higher range will drain the battery faster.
TIP: For best performance, place the Virtual Wall on the outside of the
doorway you wish to block. Set the Virtual Wall to the shortest setting
possible to extend battery life.
TIP: Scheduling Virtual Walls (when programmed) will turn on a few minutes
before Dirt Dog. See page 18 for details.
Dirt Dog is compatible with Roomba Virtual Walls. Additional Virtual Walls may
be purchased at www.irobot.com.
