HI, it's Jim from Crucial Vacuum!
If your Shark vacuum is clogged with dog hair there are a number of general maintenance cleaning tips you could perform to help keep your vacuum working at its peak performance.
First let's check out your brush roll. Is there dog hair wrapped around the roll itself? If so remove it by pulling out the dog hair, or use a razor if its tightly wrapped around. Manually rotate the brush roll to help unearth any hidden clogs behind the roll.
If there's dog hair throughout your unit be sure to empty the dust cup after every use. When the dust cup isn't emptied often this leads to clogs and a loss of suction.
Also, be sure to check your vacuums hose for any clogs, or clumps of dog hair. Stretch the hose out as far as you can. If you notice a clog in a hard to reach place use a broom handle to unclog it.
Your Shark vacuums filters may need to be replaced, or washed and may be a source for a lot of the dog hair in your vacuum. Wash and clean your unit's filter weekly. To do so, empty your filter screen outdoors to take off any excess debris and then clean under running water until the water comes out clean. Allow the filter screen to fully dry before inserting it back into the unit. This may take up to several hours.
