Quick answers
What is wrong?
OmniGrip arm tangled, jammed, or cannot release/retract. Official reset holds; forcing the mechanism can damage gears.
What you might notice
- Arm stuck extended
- Cannot release a picked-up item
- App reports arm jam
Can I fix this myself?
Often yes with careful cleaning. Difficulty: medium · about 5-20 min. If unsure or it returns after parts cleaning, use mail-in repair.
What you need
- Just your hands and a clear floor
Do this
- Press emergency stop if the arm is unsafe mid-motion.
- Remove entangled items; move the robot to an open area.
- Press and hold the two arm-reset controls together so the arm releases and retracts (per Z70 manual).
- Clear objects near the electric hatch before retrying.
- If the arm will not reset, contact Roborock or request mail-in repair — do not force the mechanism.
Parts (only if cleaning fails)
- Arm module (service)
