Robot gets stuck frequently on low thresholds, rugs, or cords; its wheels spin but it cannot free itself.

Safety first: Turn off the robot before inspecting the wheels.

Check wheels and suspension:

• Inspect the drive wheel tires for wear or smoothness; replace if the tread is worn down.
• Press down and release each wheel to ensure the suspension moves freely and springs back.

Usage adjustments:

• Remove loose cables and very thick rugs from the cleaning area.
• Avoid attaching heavy accessories that the robot was not designed for.

If traction remains poor: Replace worn wheel modules or tires. If the robot is older and the battery is weak, replacing the battery can also improve climbing ability.
