COMMON CAUSES · RANKED

Long-running jam overloading the motor MOST COMMON

A wheel that dragged hair for weeks overloads its motor until the module-level fault trips instead of the simple stuck warning.

Wheel module worn out

Gears and motors in the drive module wear with age — eufy's table sends persistent S2 cases straight to customer service.

Debris deep inside the module UNCOMMON

Grit past the wheel housing reaches the gearbox where surface cleaning can't — sometimes freed by rotating the wheel back and forth.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Deep-clean both wheels

Power off, remove wrapped hair and debris from both drive wheels, and work the wheels back and forth by hand to dislodge grit inside.

Spin-test and restart

Confirm both wheels spin freely and spring back when pressed, then run a short clean.
