Robot vacuum’s front caster wheel does not swivel or roll freely, causing dragging and navigation issues.

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 (some models may require a small tool).
• Clean axle and socket: Remove hair and debris from the caster axle and inside the socket using tweezers and a brush.
• Check rotation: Spin the caster; it should rotate smoothly. If it binds or feels gritty, replace the front caster wheel assembly.
• Reinstall: Push the caster back into the socket until it clicks and swivels freely.

When to stop: If the socket itself is damaged, the chassis may need professional repair.
