DEEBOT brushes not spinning
DIRECT ANSWER
COMMON CAUSES · RANKED
Hair wrapped around the main brush MOST COMMON
Hair winds around the roller and its end caps until the motor stalls — the official routine cleans the roller with the cleaning tool and allows a water rinse if it dries fully.
Debris in the side brush slots
ECOVACS has you pull the side brushes off and wipe brush and slot with a dry cloth — grit under the hub stalls them even when the arms look clean.
Blocked suction intake feeding the jam
The official manuals pair a blocked suction intake with brush trouble — clear the intake and empty the dust bin whenever you service the roller.
Brush worn past its service life UNCOMMON
ECOVACS' own schedule replaces side brushes every 3-6 months and the main brush every 6-12 — matted bristles and bent arms don't recover with cleaning.
HOW TO FIX IT
Hold the multi-function cleaning tool by its grip — ECOVACS' manuals warn its cutting edges are sharp — and always cut wrapped hair away from your fingers.
Power off and flip the robot
Switch the robot off and turn it over on a soft surface.
Remove the main brush cover
Push the two tabs, lift the cover away, and pull the main brush out of its bay.
Cut the roller clean
Use the multi-function cleaning tool to cut and comb wrapped hair off the roller; rinse it under water only if you dry it completely before refitting.
Service the side brushes
Pull the side brushes off their posts and wipe the brushes and their slots with a dry cloth before snapping them back on.
Clear the intake and retest
Empty the dust bin, check the suction intake for wedged debris, refit everything and run a short clean — replace any brush that still won't spin.

Side brushes — OZMO 920/950/T5, T8, N8 & T9+ series
ECOVACS groups these LiDAR generations into one accessory family — its own Buddy Kits list OZMO 920/950/T5/T8/N8 compatibility together. Clean the connector under each brush when swapping; debris there mimics a brush fault.

Main brush — N79 family & DEEBOT 500/600/601/661
ECOVACS' official schedule cleans the roller weekly with the multi-function tool (careful — its edges are sharp) and replaces it every 6-12 months; a solid-red four-beep alarm that survives cleaning means the bristles are done.

Side brushes — N79 family & DEEBOT 500/600/601/661
These DEEBOTs run two three-arm side brushes that pull straight off their posts. ECOVACS' official schedule cleans them every two weeks and replaces them every 3-6 months — sooner if the solid-red two-beep alarm keeps returning.
