Rug Doctor carpet cleaner leaves streaks or uneven cleaning lines on the carpet.

Safety: Unplug the unit before working near the brush or spray bar.

• 1. Clean spray bar: Remove the spray bar or individual nozzles and clean thoroughly. Ensure all jets spray evenly by testing with clean water.
• 2. Inspect brush: Check the brush cylinder for worn or flattened bristles, especially in the center. Replace the brush if bristles are significantly shorter in one area.
• 3. Remove debris: Clear any strings, hair, or carpet fibers from the brush housing and edges that may prevent full contact with the carpet.
• 4. Adjust usage technique: Maintain a consistent walking speed and handle angle as recommended in the Rug Doctor manual to ensure even cleaning.

Maintenance: Replace the brush assembly periodically in heavy-use environments to maintain cleaning performance.
