Robot vacuum frequently gets stuck on thresholds, rugs, or cords.

Safety first: Turn off the robot before freeing it from obstacles.

Steps to improve mobility:

• Clean and inspect wheels: Remove debris from wheel treads and wheel wells. Replace wheel modules if treads are smooth or cracked.
• Service front caster: Remove the front caster, clean hair and debris from the wheel and socket, and ensure it swivels freely.
• Modify environment: Secure or remove loose rugs, tuck away cords, and consider using virtual walls or Keep Out Zones to block problematic areas.

When to replace parts: If the robot still struggles on modest thresholds, replacing worn wheel modules or the caster assembly can improve traction and clearance.
