Carpet cleaner powers on but has very weak suction at the floorhead

Safety first: Unplug the machine before removing parts or checking for blockages.

• Check dirty water tank seal: Remove and refit the dirty water tank, ensuring the rubber gasket around the suction inlet is clean and undamaged. Wipe away debris and reseat firmly until it clicks.
• Inspect nozzle and suction channel: Remove the floorhead nozzle (if detachable) and look for lint, pet hair, or carpet fibres blocking the opening. Use a long brush or flexible rod to clear the channel.
• Clean filters: Remove the motor pre-filter and any exhaust filters. Tap off dust and rinse washable filters under lukewarm water. Allow to dry completely before refitting.
• Check hose and tools: Detach the hose and run water through it in a sink to dislodge clogs. Inspect for splits or cracks that could cause air leaks; replace if damaged.
• Test suction at inlet: With tanks removed and hose off, briefly power on and feel suction directly at the machine inlet (if accessible). Strong suction here but weak at the floorhead indicates a blockage or leak in the hose or nozzle.
