5 Things to Know About Robot Vacuum Threshold Climbing

Threshold climbing is the key difference between budget and capable robot vacuums. Budget models often avoid thresholds entirely, while capable ones use sensors to detect and climb over them.

If your home has transitions between rooms, threshold-climbing ability is a make-or-break spec. Without it, the vacuum may get stuck or refuse to clean certain areas.

Sensors are what enable threshold climbing, not just wheel size or power. Cheaper vacuums lack these sensors and simply avoid obstacles instead of attempting to cross them.

Not all robot vacuums that attempt climbing succeed on every threshold height. Check the manufacturer’s stated maximum climb height to ensure it matches your home’s transitions.

Threshold climbing is a spec you should prioritize over flashy features if you have multiple rooms. A vacuum that can’t cross thresholds will leave entire areas uncleaned.
