Numatic Intermittent Brush Motor Drive

Cordless vacuum intermittently loses brush rotation but suction continues

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

Loose connection in floor head, Broken wire in wand, Failing brush motor, Overheating brush head PCB

Safety first: Remove the battery before inspecting the head and wand.

Wiggle test: With the vacuum running (battery installed), gently move the wand and head connection (then stop and remove battery). If brush stops when moved, there is likely a cable or connector fault.
Clean connectors: Wipe electrical contacts on wand and head with a dry cloth.

If the brush still cuts in and out, the head or wand wiring may need replacement.
