How to Troubleshoot and Fix Robot Vacuums

There is no universal fix here, as each vacuum differs, as does each specific issue. However, there are some common troubleshooting steps worth considering as you try to get your vacuum back in working order.

Check the Roller Brush and Wheels

The rolling brush and wheels head over all kinds of debris and even over some rough materials, like high-pile carpets and mountains of pet dander. Give the roller brush and wheels a close look, sussing out any stuck-on or tangled debris that is causing repair issues. After all, a long string can easily get caught up in these locations during use, among other items. Clean both the brush and wheels according to the manufacturer’s instructions and remove any large pieces of detritus.

Replace the Battery

Vacuum batteries are getting better all of the time, but they still use lithium-ion designs that are prone to failure, particularly after a few years of use. Remove the battery, and give it a full charge before trying to power on the vacuum again. No dice? It’s likely time for a replacement unit. Luckily, you should be able to get a new battery from the original manufacturer.

Clean the Sensors

If your robotic vacuum is navigating poorly and regularly bumping into items of furniture, it could just be dirty sensors. A vacuum’s sensors are typically located on the bottom and the sides. Take a clean microfiber cloth and give each sensor a gentle, yet thorough, cleaning.
