DIAGNOSIS Weak suction indicates a blockage or an air leak in the system, bypassing the filters.
FIX Perform a systematic blockage check. 1) Empty the dust cup. 2) Remove and inspect the pre-motor filter and post-motor HEPA filter for proper seating. 3) Detach the hose from the pod. Check for obstructions by looking through it. 4) Detach the wand from the hose and nozzle. Check each segment. 5) Inspect the floor nozzle inlet and the brush roll chamber for a clog. Reassemble, ensuring all connections click securely into place.
IF THAT DIDN'T WORK A leak is likely. The most common leak point is a crack in the clear plastic elbow where the hose attaches to the dust cup lid. Inspect this part for hairline fractures. Also check the seal around the dust cup itself.
HEADS UP After washing the foam and felt pre-motor filter, it must be air-dried for a full 24 hours before reinstallation. A damp filter will drastically reduce airflow and cause weak suction.
