Carpet cleaner leaves streaks or lines of dirt on the carpet after passes.

Safety: Unplug the unit and remove the tanks.

• Inspect brush bristles: If bristles are worn down or uneven, replace the brush roll.
• Clean spray bar: Remove the spray bar and clean each nozzle with a soft brush or toothpick. Soak in warm vinegar if limescale is present.
• Clean suction lips: Wipe the front and rear rubber lips on the cleaning head to remove lint and residue.
• Adjust cleaning technique: Move the cleaner slowly and overlap passes to ensure even coverage.
