Check the vacuum hose for a clog when suction stays weak

Vacuum bag

When the bag or bin and filters look fine but pickup is still weak, detach the hose, look for light through it, and clear debris with a blunt rod — not a sharp wire.

Bags and filters get the blame first — and they should. But if you already emptied the bin or swapped the bag and checked the filters, a sock, toy, or hair wad in the hose can still kill pickup at the floor head.

Find the clog in the hose

  1. Unplug the vacuum. Detach the hose from the machine and from the wand or floor head.
  2. Hold the hose up to a light or shine a flashlight through one end. If you cannot see daylight, you found the choke point.
  3. Gently push the blockage out with a blunt broom handle or flexible cleaning rod. Do not jab with a sharp wire that can puncture the hose.
  4. Reattach, then feel suction at the open hose cuff before you reconnect the floor head. Strong at the cuff but weak at the head means look in the wand or nozzle next.

Honest stop

A burning smell, sparks, or powder spilling into the motor area means stop and service the machine. Do not keep running a vacuum that smells hot with a clear hose.
