Robot vacuum won't charge? Diagnose it in 10 minutes
Charging contacts, dock placement, and isolation steps that tell you whether the problem is the dock, the cable, or the battery.
Fix it yourself: diagnosis and repair guides for robot vacuums
DIY diagnosis & repair
Most robot vacuum failures are small, cheap, and predictable: dirty charging contacts, a worn brush, a confused sensor, or a battery past its prime. These guides walk you through diagnosing the problem and fixing it with basic tools — no service center, no guesswork, no replacing the whole unit.

Bumper sensors, wheel encoders, and cliff sensors — the usual suspects behind circular behavior and what to do about each.
Why dark rugs look like staircases to your robot, how to clean the sensors, and placement workarounds that actually help.
How to recognize worn brushes, the generic steps to swap them, and a maintenance cadence that keeps suction strong.
How to tell the battery is dying, the safety precautions that matter, and a generic procedure for swapping it.
A debris jam, a lying wheel sensor, or a dead motor: an isolation procedure that tells you which — and when cleaning is no longer enough.
Identify your navigation hardware, clean the turret window and apertures, test the spin — for any model with a spinning laser sensor.
Weak suction is almost always maintenance: a step-by-step sequence that finds the culprit, plus washable-vs-disposable filter care.
