Dual Mode Virtual Wall Barriers
The Dual Mode Virtual Wall barrier (an optional
accessory) keeps the Roomba in the places
you want to be cleaned — and out of the ones
you don’t. You can set your device to one of two
modes to suit your home’s cleaning needs:
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 metres). It
creates an invisible, cone-shaped barrier that
only the Roomba can see.
Note:
This barrier gets wider as it gets further
from the device (refer to the illustration).
Halo Mode:
When the switch is in the “down”
position (
), the device creates a protective
zone that the Roomba will not enter. This
prevents the 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
centimetres) from the centre of the device.
