Poor water pickup on a Kärcher FC7 can follow misfitted hair filters or worn rollers that no longer contact the floor correctly. Separate tank seating, liquid flow, suction and brush drive before ordering a part. Empty dirty water, keep electrical areas dry and run only the short test described for this exact model family. What the alert means: The pickup geometry depends on correctly seated hair filters and rollers with enough profile to move dirty water toward the tank. What to distinguish first: Check for even roller contact and verify both hair filters click into place; streaks on one side reveal a seating problem. 1. Confirm the exact symptom — The pickup geometry depends on correctly seated hair filters and rollers with enough profile to move dirty water toward the tank. 2. Prepare safely — Switch off, unplug the charger and empty both tanks before removing a roller, filter or floorhead cover. 3. Apply the official check — Remove and clean the hair filters, reinstall them in their marked sides and inspect the rollers for flattened or damaged fibres. 4. Interpret one retest — Test one straight pass. Replace the verified rollers if contact remains uneven; seek service if pickup is still poor. The official Kärcher procedure identifies this exact symptom and supports the checks above. Keep the charging port and motor vents dry, and never clear a blockage while the appliance can start. Stop for a damaged tank, battery heat, electrical smell, persistent leak or an error that returns after one clean test.
