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

Safety first: Turn the robot OFF before working on the caster wheel.

Steps:

• 1. Remove caster wheel: Pull the front caster wheel assembly straight out of its socket (most designs allow this).
• 2. Clean axle and housing: Remove hair and debris from the wheel and axle. Clean the socket in the robot body.
• 3. Check rotation: Spin the wheel by hand; it should rotate freely. If it feels rough or sticks, replace the caster wheel assembly.
• 4. Reinstall: Push the caster back into its socket until it clicks.

When to call a technician: If the caster mount is damaged or the wheel cannot be removed, professional service may be needed to replace the assembly.
