The Dual Mode Virtual Wall barrier keeps
Roomba in the places you want to be
cleaned— and out of the ones you don’t.
Inbetween cleaning cycles, you can leave the
device operating in its position on the floor.
Youcan set your device to one of two modes
tofit your home’s cleaning needs:
Note: Under normal use, batteries will last 8-10 months. If you are not planning on
using your Virtual Wall device for an extended period of time and you would like to
store it, be sure to switch it to the “O ” (middle) position.
Using Dual Mode Virtual Wall Barriers
(optional accessory for all models)
Virtual Wall Mode: When the switch is in the “up”
position ( ), the device functions as a Virtual
Wall. This means that you can set it to block
openings of up to 10 feet (3 meters). It creates
an invisible, cone-shaped barrier that only
Roomba can see.
Note: This barrier gets wider as it gets
further from the device (refer to illustration).
Halo Mode: When the switch is in the “down”
position ( ), the device creates a protective
zone that Roomba will not enter. This prevents
Roomba from bumping into items you want to
protect (e.g. a dog bowl or vase) or crossing
into undesired areas (e.g. a corner or under
a desk). The Halo is invisible and reaches
approximately 24 inches (60 centimeters)
from the center of the device.
To keep Roomba running at peak performance, perform the
following care procedures. If you notice Roomba picking up less
debris from your floor, then empty the bin, clean the filter and
clean the extractors.
