This is the floor mat that sets up under delicate items and repels Roombas or Scoobas as they clean. The mat can be placed under pet bowls or potted plants and uses the robotic cleaner's ledge-detection sensor to make the device think it's approaching a staircase, causing the robot to turn away. The mat has a gentle adhesive backing that provides stability on any carpet or hard surface floor and it is made from durable polypropylene for years of use. Unlike virtual walls, the mat does not require any power, and at only 1/4" high it won't impede foot traffic. 22" L x 18" W x 1/4" H. (2 lbs.)
