Robot vacuum’s front caster wheel does not swivel freely, causing navigation issues or drag marks.

Safety first: Turn off the robot and flip it over.

Step-by-step:

• Remove caster wheel: Pull the front caster straight up to remove it from its socket.
• Clean axle and socket: Remove hair and debris from the axle and inside the socket. Wipe with a dry cloth.
• Inspect wheel: Spin the wheel on its axle. If it binds or has a flat spot, replace the caster assembly.
• Reinstall: Push the caster back into the socket until it clicks and swivels freely.

Test the robot’s movement; it should roll smoothly without dragging.
