iRobot 4150, 400 owner manual Slim Virtual Wall models

Virtual Wall®

(optional accessory for select models)

Virtual Walls create an invisible barrier that Roomba will not cross. This invisible barrier can be used to confine Roomba to a particular room or area, and prevent it from getting too close

to electrical or computer cords, delicate objects on the floor, etc.

The Virtual Walls can be set to block an opening up to seven feet long. Note that the width of the Virtual Wall’s beam also increases as its length increases,

creating a cone-shaped area which Roomba cannot pass. The Virtual Wall also creates a halo of protection around itself, preventing Roomba from getting too close.

TIP: For best performance, place the Virtual Wall on the outside of the doorway you wish to block.

Slim Virtual Wall (models 400-420)

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. Use the slider bar to adjust the length of the barrier.

A higher range will drain the battery faster.

TIP: Point the iRobot logo towards the opening you would like to block.

TIP: Scheduling Virtual Walls (when programmed) will turn on a few minutes before Roomba.
