What to do when your Dyson canister vacuum isn't suctioning well

A weak suction motor, full vacuum bag, clog in the suction air path, dirty vacuum exhaust filter or leaky vacuum hose can prevent the vacuum cleaner from suctioning well.

Check the collection bag because debris won't get sucked up through the vacuum and into the collection bag efficiently when the bag is full. Empty the bag if it's full.

If your vacuum uses an exhaust filter, a clogged exhaust filter will prevent suction air from flowing through the vacuum efficiently. Check the exhaust filter and replace it if it's dirty.

Check the suction air path for a clog. Debris in the nozzle, hose or an internal pipe in the vacuum can inhibit suction air flow so remove any debris that you find blocking the suction air path.

Holes in the vacuum hose can diminish suction air flow through the nozzle because air gets sucked through hose holes instead of the nozzle. Replace the vacuum hose if it has holes.

Common repair parts for Dyson canister vacuum cleaners

• Adjustable wand. The adjustable wand is a stiff suction tube that attaches to the cleaning head at one end and the vacuum hose at the other end. The wand telescopes, so its length can be adjusted. The wand transfers dirt from the cleaning head to the vacuum hose. The wand has a handle at the end that enables the user to maneuver the cleaning head.
• Dirt sensor. The dirt sensor is a set of optic lenses that detects the amount of dirt and debris moving through the vacuum hose to the collection bag in the vacuum.
• Suction motor. The suction motor rotates the vacuum fan assembly to create suction in the vacuum.
• Vacuum hose. The vacuum hose runs from the cleaning attachment to the dirt collection chamber in the vacuum cleaner.
