How to Unclog a Vacuum Hose
To unclog a vacuum hose: disconnect it, walk a broomstick through from the wand end (not the canister end), look for cracks where air can leak, and reinstall. Most clogs clear in 2 minutes.
Causes, ordered by likelihood
- Cat litter, kid toys, jewelry. Most common clog material. The broomstick-walk pushes them out.
- Hair wad. A dense hair wad can clog mid-hose. Sometimes needs a hook to extract.
- Crushed hose. Older hoses develop crushed sections that act like a clog from the airflow perspective.
What to check at home
- Unplug the vacuum and disconnect the hose at both ends.
- Look through the hose from one end with a flashlight. Spot the clog.
- Walk a broomstick or long stick through from the wand end (smaller diameter end). The clog should push out the larger canister end.
- Run your hand along the hose checking for cracks or crushed sections.
- Reinstall. Test.
When to bring it in
Bring it in if the clog won't push through, if the hose is cracked or crushed, or if the diagnostic points at the powerhead path instead of the main hose.

Brand-specific notes
- Dyson
- V-series tool wand can clog separately from the main hose. Check both.
- Miele
- Miele canister hoses are SuctionControl-equipped on newer models; the control switch can also fail and mimic a clog.
- Central vacuum
- Central vacuum clogs require accessing the inline cleanout door, usually in the basement.
Common questions
- Can I use a coat hanger to unclog?
- Yes, carefully. A wire hanger straightened out works for shallow clogs. Don't push hard; you can crack the hose.
- How much does it cost to replace a vacuum hose?
- Replacement hoses run $40 to $120 depending on brand and length. Bench install is included.
