A dock can slide on a slick or uneven surface, lack wall support, have the wrong clearance or be approached with dirty sensors. Push the dock against a wall on a stable surface and watch one docking from a short distance.

Differential
Likely causes of “Robot vacuum pushes or moves its charging dock”, and how to tell them apart
- 1
The dock is on a smooth floor and slides when the robot returns
What separates it The dock is displaced a little after every docking and never sits square to the wall.
How to confirm Push the dock against a wall on a stable surface and watch one docking from a short distance.
- 2
The dock has no wall behind it or too little clearance
What separates it The robot approaches wide, pushes the dock aside and tries again.
How to confirm Check the manual's front and side clearance and confirm the dock is against a solid wall.
- 3
Dirty sensors make the approach clumsy
What separates it The robot fails to line up and hits the dock at an angle, particularly in a bright room.
How to confirm Wipe the robot's docking sensors and the dock's signal window with a dry cloth.
- 4
Something under the dock's feet is stopping it gripping
What separates it The dock rocks or the feet look dusty or worn.
How to confirm Clean the anti-slip feet and confirm the dock sits flat on the surface.
Before you touch a setting
Record this first — changing settings destroys the evidence
- The floor type under the dock and how far it moves per docking.
- How the robot approaches: straight in, or in a wide curve with several attempts.
- Whether the dock power light stays on during the approach.
Try in this order
0 of 4 completedObserve before changing anything
ReversibleCheck dock placement, power, front/side clearance and whether its anti-slip feet are clean.
Isolate the failing boundary
ReversiblePlace it flat against a stable wall on an approved surface and clean robot/dock sensors and contacts.
Apply the narrow correction
ReversibleCommand Dock from a short distance and confirm a straight approach and charge indication.
Verify the result and stop at the boundary
ReversibleDo not tape over sensors or block required ventilation.
Stop boundary
When this stops being a self-service repair
- !Do not tape over sensors or block the vents to hold the dock in place; that stops it charging correctly.

Common questions
Can I stick the dock to the floor?+
Only with a method the maker approves, and never over the charging contacts or vents. Start with a stable surface and a wall behind the dock.
Why does the dock move?+
Slick floors or no wall support.
How can I fix it?+
Place it against a wall and use grip pads.
Does clearance matter?+
Yes.
