Model issues and repair guidance
Separate a single weak inlet from a system-wide complaint before opening the wall canister. Check the hose and branch first; broad loss belongs at the disposable bag, dock, chamber gasket, and motor protection path. On the shortest cabinet, confirm the bottom bag does not interfere with the two-latch canister seal; an uneven closure can mimic broader suction loss at every inlet.Compare the direct port with several wall inlets, then inspect bag fill, collar, chamber seal, and filter before fan or motor work. Confirm the bottom bag clears the two-latch rim and closes evenly, since a poor seal can weaken every inlet.
