Brushroll spins intermittently or stops under light load

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn brushroll end bearings, Stretched or slipping drive belt (if fitted), Weak or failing nozzle motor, Debris in brushroll housing

Safety: Remove the battery and detach the nozzle.

Clean brushroll: Remove the brushroll and clear all hair and fibers from bristles and end caps.
Check bearings: Spin the brushroll by hand. If it feels rough or stiff, replace the brushroll assembly.
Inspect belt (if applicable): On belt-driven models, check for glazing, stretching, or cracks. Replace if worn.
Test nozzle motor: With the brushroll removed, briefly run the nozzle (if safe to do so) to see if the motor shaft spins strongly. Weak or non-spinning indicates motor failure.
