3 Ways to Stop a Robot Vacuum From Getting Stuck Under a Sofa

Use furniture risers Lift the sofa legs with plastic or metal risers to add one or two inches of clearance. Most robot vacuums need 3.5 to 4 inches to navigate underneath, and risers are cheap ($10–$20) and easy to install.

Place a magnetic boundary strip If you don’t want to raise the sofa, lay a magnetic strip along the front edge to block the robot. This works without altering the furniture’s appearance.

Install a physical barrier Use a piece of baseboard trim or similar material under the sofa’s front edge. This prevents the robot from driving underneath without raising the entire piece of furniture.
