Vacuum lost suction — check bag and filters

Vacuum bag

Restore vacuum suction by changing the bag before it packs solid, cleaning filters, clearing hose and brush-roll hair, and reseating seals.

A vacuum that suddenly feels weak usually has a full bag, packed filters, or a clog in the hose — not a mysterious motor failure. Work the airflow path before you assume the machine is done.

Bag first

Change the bag before it is packed rock-solid. Many bags lose suction once they are two-thirds full, especially with fine dust. Match the bag type and collar to your model — the wrong collar leaks air and kills pickup. See Match your vacuum bag or filter type.

Filters next

  1. Clean or replace the pre-motor filter (often foam or pleated).
  2. Check the exhaust / HEPA filter if your model has one.
  3. Let washable filters dry fully before reinstall — a damp filter can smell musty and restrict flow.

Hose, wand, and brush roll

Detach the hose and wand; push a blunt broom handle or the maker’s flexible tool through to clear socks, hair clumps, or debris. Flip the machine and cut hair wrapped around the brush-roll bearings — a stalled roll feels like weak carpet suction even when the hose is clear.

Reseat seals

After a bag or filter change, close every door firmly so gaskets seal. A slightly ajar dust cover dumps suction at the crack.

When to stop

Unplug and stop if the motor smells hot or burning, the breaker trips, or the machine screams with a clear hose and fresh filters. That is service territory — this guide does not cover opening sealed motor housings.
