Clean the dust cup and filter first
The dust cup and filter are where most dirt collects, so they need cleaning before anything else. Empty the dust cup by pressing the release button on the side and pulling it away from the main unit. Tap the cup over a trash bin to dislodge loose dust, then rinse it under warm running water. Let it dry completely — at least 30 minutes — before you put it back.
The filter sits inside the dust cup. Tap it gently against the trash bin to shake out dust, then rinse it under warm water as well. Never use hot water on the filter, as heat can damage the material. If the filter looks clogged or discolored after rinsing, replace it with a new one; Shark sells replacement filters that fit your model number, which you can find on the back of the vacuum.
Key Takeaways
- Empty and rinse the dust cup and filter after every few uses, and let both dry completely before reassembling.
- The brush roll collects hair and fibers and should be cleared of tangles every month or whenever you notice reduced suction.
- Check the hose and intake ports for blockages by holding them up to light or running water through them.
- Wipe down the exterior with a damp cloth and inspect the wheels and seals for debris that reduces performance.
Clear the brush roll of hair and fibers
Hair wraps around the brush roll and slows it down. Flip the vacuum over and look at the brush roll — the spinning cylinder at the bottom. You will see hair wound around it. Use scissors to cut the hair away, working along the length of the roll. Take your time here; pulling too hard can damage the bristles.
Once you have removed the visible hair, wipe the brush roll with a damp cloth to pick up any remaining fibers. If the brush roll does not spin freely after cleaning, or if the bristles look worn or matted, the roll may need replacement. Shark sells replacement brush rolls for most models, and swapping one out takes about five minutes.
Check the hose and intake ports for clogs
A blocked hose or intake port kills suction even when the filter is clean. Detach the hose from the main unit by twisting or unclipping it, depending on your model. Hold it up to a light source and look through it. If you see a blockage, use a straightened wire coat hanger or a plumbing snake to push it out, or run warm water through the hose to flush it.
Next, check the intake ports on both the main unit and the lift-away canister. These are the openings where air enters. Wipe them with a damp cloth or use a small brush to clear dust and debris. If you see a clog you cannot reach, a thin wooden dowel or the handle of a wooden spoon can help push it through without scratching the plastic.
Inspect and clean the wheels and seals
Wheels collect hair, dust, and debris that can make the vacuum harder to push. Flip the unit over and look at the wheels on the bottom. Use your fingers or tweezers to pull out any hair or fibers wrapped around the axles. Wipe the wheels themselves with a damp cloth to remove caked-on dirt.
While you are there, check the rubber seals around the dust cup and the connection points between the lift-away canister and the main unit. Dirt on these seals reduces suction and can cause the unit to lose its seal. Wipe them with a damp cloth and make sure they are not cracked or peeling. If a seal is damaged, you may need to order a replacement part from Shark.
Wipe the exterior and check connections
The outside of the vacuum collects dust and grime. Use a damp cloth to wipe down the plastic body, the handle, and any vents. Pay attention to the seams and crevices where dust settles. Do not use harsh chemicals or abrasive scrubbers; warm water and a soft cloth are enough.
While cleaning, inspect the connection points where the lift-away canister attaches to the main unit. Make sure the clips or latches are not bent or broken, and that the connection feels snug when you reattach the canister. A loose connection reduces suction and can cause the unit to feel unstable when you are vacuuming.
How often to clean each part
The dust cup and filter should be emptied and rinsed after every 2 to 3 uses, or whenever you notice the suction dropping. The brush roll needs clearing of hair about once a month, or more often if you have pets. The hose and intake ports should be checked every few months, or sooner if you notice a sudden loss of suction.
The wheels and seals can be wiped down during your regular dust cup cleaning. The exterior can be wiped whenever it looks dusty — usually once a month. If you use the vacuum several times a week, you may need to clean more often. The key is to act as soon as you notice reduced suction, because a clogged filter or brush roll makes the motor work harder and wears it out faster.
Frequently Asked Questions
Can I wash the dust cup in the dishwasher?
No. Hand wash the dust cup in warm water and let it air dry. Dishwashers use hot water and harsh detergents that can warp the plastic or damage the seals. Warm water and a soft cloth are all you need.
What if water comes out when I rinse the filter?
That is normal. The filter is designed to trap water as well as dust. Gently squeeze the filter to remove excess water, then stand it upright to dry. Do not wring it or twist it, as that can tear the material. It should be completely dry before you use the vacuum again.
How do I know if the brush roll needs to be replaced?
If the bristles look matted, frayed, or significantly shorter than they were when new, or if the roll does not spin freely after cleaning, it is time for a replacement. A worn brush roll does not pick up dirt as well and can damage carpet fibers.
Is it safe to use the vacuum while parts are drying?
No. Always let the dust cup and filter dry completely before reassembling. Using the vacuum with a wet filter reduces suction and can damage the motor. Set aside at least 30 minutes of drying time after rinsing.
What should I do if suction is still low after cleaning everything?
Check the hose and intake ports again for blockages you may have missed. If those are clear, the filter may be permanently clogged and need replacement. If the filter is new and suction is still low, the motor may be failing and the vacuum may need service.
