Troubleshooting
Robot Vacuum Stuck Under Furniture: Causes and Fixes
A robot that keeps getting wedged under the same sofa or bed is almost always dealing with a gap that is too low, a sensor that is confused, or an obstacle it cannot see. Work through these checks in order.
Quick answer
Measure the gap under the furniture and compare it to your robot's stated height (see the clearance database). If the gap is close to or below that number, block the space with a no-go zone or raise the furniture. If the gap is fine, clean the sensors and rebuild the map.
Check the gap first
Measure from the floor to the lowest part of the frame at the narrowest point. A robot at or near the gap height can enter but jam on trim, cross-bars, or a rug edge. If your robot's manual does not state a height, measure the robot itself at its tallest point.
Look at what it is stuck on
- Sofa skirts and bed valances that fold under the robot.
- Furniture feet, cross-bars, or storage-box edges just inside the opening.
- Cables or cords under the furniture — see keeping robots away from cords.
- A rug edge at the entry that lifts the robot into the frame.
Clean the sensors
Dusty cliff and obstacle sensors can make a robot misjudge a low ceiling or drop. Wipe them as described in how to clean robot vacuum sensors, then retest the same spot.
Use the map to keep it out
Draw a no-go zone or virtual wall across the opening in the app (step by step). If the robot keeps returning, re-run mapping so the zone is anchored to the correct place. If it circles rather than sticks, see stuck in a loop.
Change the furniture or the robot
Small risers can add the missing height, or you can leave that space for a manual pass. If low furniture is the norm in your home, see robot vacuums with a stated low height — and measure first; not every listing publishes one.
When to contact the manufacturer
If the robot is well within its stated clearance and still jams, or the sensors report errors, use the manufacturer's support page — the model-specific manual will say more than a general guide can.
Frequently asked questions
Why does my robot vacuum keep getting stuck under the same couch?
The usual causes are a gap close to the robot's height, a sofa skirt or cross-bar it cannot clear, or a rug edge at the entry. Measure the gap, then block the space with a no-go zone if it is too tight.
Can I stop it going under furniture at all?
Yes — draw a no-go zone or virtual wall across the opening in the manufacturer's app, or block the space physically.
Will a different robot fix it?
Only if it is short enough for your gap. Compare stated heights, but note that not every manufacturer publishes one.
