Rug Doctor upholstery or stair tool has no suction, while the main floor head suction is normal.

Safety: Unplug the unit before disconnecting hoses.

• 1. Check hose connection: Ensure the accessory hose is fully inserted and locked into the machine's tool port.
• 2. Clear tool nozzle: Inspect the upholstery tool head for lint, hair, or debris blocking the suction opening. Clean thoroughly.
• 3. Check hose for clogs: Detach the hose at both ends and look through it. Use a flexible brush or water (then dry completely) to clear blockages.
• 4. Verify diverter valve: Some models have a suction diverter lever. Ensure it is set to the TOOL or UPHOLSTERY position. If the valve is stuck, clean and lubricate or replace the diverter assembly.

Note: Always follow Rug Doctor instructions for switching between floor and tool modes.
