Auto Virtual Wall For Roomba 500 Series

The Auto Virtual Wall prevents Roomba from entering areas that are off-limits. This model saves you a step, remaining constantly on so you don't have to remember to turn it on/off.

• The Auto Virtual Wall uses an infrared beam, preset for 1 to 3 metres, to block Roomba from doorways and other off-limit areas. And you never have to remember to turn it on or off! Auto Virtual Walls remain on for up to six months
• Requires 2 C batteries, not included
