Carpet cleaner moves very stiffly or wheels do not roll smoothly.

Safety first: Unplug the unit before tilting or working underneath.

• Inspect wheels: Turn the unit over and check for hair or fibers wrapped around the wheel axles. Remove with scissors or tweezers.
• Check wheel rotation: Spin each wheel by hand. If rough or seized, remove the wheel and clean or replace it.
• Inspect axle: If the axle is bent, replace the axle or wheel assembly as a unit.
