Frequently asked questions

Why does my Roomba’s side brush occasionally spin backwards?

When caught on items such as carpet tassels or wires, the side brush may spin slowly or even backwards to free itself. This may also occur on thick carpets. If it does this at other times, you should clean the brush.

Why does my Roomba occasionally make a thumping sound?

When Roomba’s brushes encounter items such as carpet tassels or wires, the brushes will briefly reverse direction to get free. This makes a thumping sound. If you hear a thumping sound at any other time, you should clean the main brushes.

Why doesn’t my Roomba slow down as it approaches certain obstacles?

Your Roomba usually identifies obstacles quickly, allowing it to slow down and gently touch the obstacle with its bumper before changing direction. However, it may be less effective at sensing extremely dark surfaces, or objects under 2 inches (5 centimeters) wide.
