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

Safety first: Unplug the unit and lay it on its side.

• Inspect wheels: Rotate each wheel by hand. Remove hair, threads, or debris wrapped around the axles.
• Check bearings: If wheels feel rough or seized, replace the wheel assemblies or bearings.
• Inspect axle: Ensure the axle rod is straight and properly seated in its brackets.
• Lubricate lightly: Apply a small amount of suitable lubricant to metal axles (avoid getting lubricant on carpets).
