Shark Rocket HV322 Losing Suction

Clean the dust cup by emptying the internal debris into the trash. If there is anything too large stuck in the debris screen, you may need to reach into the dust cup and clean it. Be sure to close the duct cup, reattach the unit, and check suction.

Disconnect the hose from the wand and the wand from the nozzle, so you have three separate parts. Inspect each part for large blockage or excess debris. Attach in the same order you took apart and check suction.

Remove air filter from entire unit. Remove any debris over the trash. Put filter back into unit, reattach filter cover, and check suction.

Lay vacuum down so the underside of the underside of the intake port (where your brush roll is) is visible. Check for long, tangled hairs as well as large debris stuck in this area. Once completely cleaned, flip over and check suction.
