Carpet cleaner has weak suction, poor pickup of water and debris from carpet

Safety: Unplug before cleaning filters or hoses.

• Check hose and tools: Remove the hose and attachments. Look through them and clear any partial blockages with a flexible brush.
• Clean or replace filters: Remove pre-motor and exhaust filters (if fitted). Tap out dust or wash if the manual allows. Replace heavily soiled or damaged filters with genuine Miele parts.
• Inspect tank seals: Check the gaskets around the dirty water tank lid and where the tank meets the body. Replace flattened or cracked seals to prevent air leaks.
• Test suction at inlet: With the hose removed, test suction directly at the machine inlet. If still weak, the motor or internal ducts may be restricted and require professional service.
