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

Safety first: Turn off the robot and flip it over on a soft surface.

Steps to resolve:

• Remove caster: Pull the front caster straight up to remove it from its socket.
• Clean thoroughly: Remove the wheel from the caster housing (if possible) and clear hair and debris from the axle and socket.
• Check rotation: Ensure the wheel spins freely and the caster swivels smoothly. Lubricants are generally not recommended; rely on cleaning.
• Reinstall: Push the caster back into its socket until it clicks.

When to replace parts: If the caster still binds or wobbles, replace the front caster wheel assembly.
