Empty the dust cup and rinse the filter first

Start by unplugging the vacuum, then press the dust cup release button on the handle and pull the cup away from the main unit. Empty all debris into a trash bin, tapping the sides to dislodge stuck dirt. Rinse the cup under warm running water — do not use hot water, which can warp plastic. Let it air-dry completely before reattaching.

Next, locate the filter, which is usually a cylindrical or cartridge-style component near the top of the dust cup or inside the main unit. Tap it gently over a trash bin to remove loose dust, then rinse it under cool water. Never use soap or submerge it fully unless your model's manual says it is safe. Allow at least four hours of air-drying before putting it back in place.

Key Takeaways

  • Empty the dust cup and rinse the filter after every few uses to maintain suction power and prevent clogs.
  • The lift-away canister detaches from the main unit and can be cleaned separately with warm water and a soft brush.
  • Check the brush roll monthly for hair and debris wrapped around the bristles, and cut away tangled fibers with scissors.
  • Clean the hose by running water through it or using a straightened coat hanger to push out blockages.
  • Dry all parts completely before reassembling to prevent mold and motor damage.

Clean the brush roll and remove tangled hair

The brush roll — the spinning bristle bar at the bottom of the vacuum head — collects hair, string, and fibers that reduce cleaning power. Unplug the vacuum and flip it over to access the brush roll. Look for a release latch or clip on either side of the head; slide or press it to remove the cover plate.

Use scissors or a seam ripper to cut away any hair or string wrapped around the bristles. Work slowly to avoid cutting the bristles themselves. Once cleared, spin the brush roll by hand to check that it rotates freely. If it still feels stiff, the bearings may need replacement — check your model's manual for the part number and whether this is a user-replaceable component.

Detach and rinse the lift-away canister

The lift-away feature is one of the Shark's main selling points, and the canister needs its own cleaning routine. Press the release button near the handle to separate the canister from the main unit. Empty any remaining dust into the trash, then rinse the canister under warm water. Use a soft brush or cloth to wipe the interior walls and remove dust buildup.

Pay special attention to the connection point where the canister attaches to the main unit — dust accumulates there and can interfere with the seal. Wipe this area with a damp cloth on both the canister and the main unit. Dry the canister thoroughly with a towel before reattaching it, as moisture can damage the motor or create mold.

Clear blockages from the hose and intake ports

A clogged hose is the most common reason a Shark loses suction. Detach the hose by twisting or unclipping it from the main unit — the exact method depends on your model. Hold it up to a light and look through it; if you cannot see light, there is a blockage.

Run warm water through the hose from one end to the other, letting it flow out the other side. If water does not flow freely, straighten a wire coat hanger and carefully push it through the hose to dislodge the clog. Work from both ends if needed. Once clear, hang the hose vertically and let it drain and air-dry completely before reattaching. Also check the intake ports on the main unit and canister for debris, and wipe them clean with a damp cloth.

Wipe down the exterior and check seals

Use a damp microfiber cloth to wipe the outside of the vacuum, the handle, and the canister. This removes dust that settles on the surface and keeps the unit looking clean. Pay attention to any vents or air intake areas, as blocked vents reduce airflow and motor efficiency.

Inspect the rubber seals where the canister connects to the main unit and where the hose attaches. These seals keep air from leaking, which is essential for suction. If a seal looks cracked, dried out, or loose, it may need replacement. Check your model's manual for the correct seal part and whether it is a straightforward swap or requires tools.

Replace the filter if it stays clogged after rinsing

If you rinse the filter and it still feels clogged or suction does not improve, the filter has reached the end of its life. Shark filters typically last three to six months depending on how often you vacuum and the amount of pet hair or dust in your home. Replacement filters are available from Shark's website or major retailers — search for your model number to find the correct part.

Install the new filter by sliding it into the slot where the old one sat, making sure it is fully seated. Run the vacuum briefly over a hard floor to confirm suction has returned. Keep the old filter for reference if you need to order a replacement later.

Store the vacuum in a dry location

After cleaning, store the Shark in a cool, dry place away from direct sunlight and moisture. Damp basements or garages can cause rust on metal parts and mold growth inside the motor. If you live in a humid climate, consider storing the vacuum with the dust cup removed so air can circulate inside the unit.

Keep the manual and any spare parts — like replacement filters or belts — in a plastic bag near the vacuum so you can find them quickly when needed. Check the power cord for cracks or damage before storing, and coil it loosely rather than wrapping it tightly around the unit, which can damage the insulation over time.

Frequently Asked Questions

How often should I clean the filter?

Rinse the filter every two to four weeks if you vacuum regularly, or more often if you have pets or allergies. A clogged filter reduces suction and makes the motor work harder. If rinsing no longer restores suction, replace the filter with a new one.

Can I wash the brush roll with soap and water?

Yes, you can rinse the brush roll under warm water after removing it from the head. Use a soft brush to clean between the bristles, but do not soak it or use hot water. Dry it completely before reinstalling it.

What should I do if the canister does not seal properly?

Check that the canister is fully clicked into place and that the rubber seal is clean and not cracked. If the seal is damaged, you will need to order a replacement seal from Shark. If the seal looks fine but the canister still leaks air, the connection point on the main unit may be dirty — wipe it with a damp cloth and try again.

Is it normal for the vacuum to smell after cleaning?

A musty smell usually means moisture is trapped inside. Make sure all parts are completely dry before reassembling, and store the vacuum with the dust cup removed if possible. If the smell persists, the filter may be moldy and needs replacement.

Can I use a regular vacuum hose to replace a clogged Shark hose?

No — the hose connection is specific to Shark models and will not fit other brands. Order a replacement hose from Shark using your model number. In the meantime, try clearing the blockage with a coat hanger or by running water through it.
