Roborock Error 7 — Wheels jammed

Severity: Warning — robot stops driving until the main wheels turn freely S5S6S7S8Q
Last verified: 2026-07-05 Tools: none Time: ~5 min Difficulty: easy

DIRECT ANSWER

Error 7 means a main wheel is jammed. Something is physically stopping it from turning — hair around the axle, a cable, or carpet fringe. Press and spin each wheel by hand, free it, and restart.

COMMON CAUSES · RANKED

1

Hair or string around the axle MOST COMMON

Fibres work their way into the wheel hub and tighten with every rotation.

2

Object wedged in the wheel well

Small toys, socks and carpet fringe jam between tyre and housing.

3

Worn wheel module RARE

If a wheel grinds or wobbles with nothing stuck in it, the motor gearbox in the wheel module is wearing out.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Spin both wheels by hand

Flip the robot over. Press each main wheel and spin it — official advice straight from Roborock. Both should turn with steady resistance.

Remove whatever is stuck

Pull hair off the axles and pry out anything wedged in the wheel wells.

Check the caster wheel too

The small front caster collects hair as well. Pop it out and clean the bearing.

Restart in a new spot

Move the robot somewhere open and start again. A wheel that still grinds needs a replacement wheel module.
