Empty the bin and rinse the filter before anything else

The first step is to empty the dust bin and wash the filter—do this every time you vacuum, or at least once a week. Dyson upright vacuums have a large bin at the back of the machine. Press the red release button on the bin's side, pull it straight out, and hold it over a trash can. Press the button inside the bin to open the bottom door and let the dust fall out. Tap the bin a few times to dislodge stubborn dust.

Next, locate the filter. On most Dyson uprights, it sits on top of the machine under a plastic cover. Twist the cover counterclockwise and lift it off. The filter looks like a tall, pleated cylinder. Tap it gently over a trash can to shake out loose dust, then rinse it under cool running water. Do not use hot water or a dishwasher. Squeeze the filter gently while rinsing—do not wring it. Let it air-dry completely (at least four hours, or overnight) before putting it back. A wet filter will damage the motor.

Key Takeaways

  • Empty the bin and rinse the filter weekly to keep suction strong and prevent motor damage.
  • The brush bar should be cleaned every three months or whenever you see hair wrapped around it, using scissors or a coin to remove tangles.
  • Check the air pathway—the tube that connects the head to the bin—for blockages by holding it up to light and clearing any clogs with a straightened wire coat hanger.
  • Wash the bin itself with warm soapy water and dry it completely before reassembling to prevent mold and odors.
  • Replace the filter every 12 months or sooner if it looks gray or clogged, because a dirty filter reduces suction and strains the motor.

Clean the brush bar and remove hair tangles

Hair and fibers wrap around the brush bar (the spinning roller at the bottom of the head) and reduce suction. Check it every time you vacuum and clean it at least every three months. Unplug the vacuum and flip it over so you can see the brush bar. You will see a row of clips or a release button along the edge of the head. On most models, you slide these clips toward the center to unlock the head, or press a button to pop the head off.

Once the head is off, use scissors or a coin to scrape hair and lint away from the brush bar. Work along the entire length. If hair is tightly wound, use a seam ripper or old credit card to cut and lift it. Wipe the brush bar with a damp cloth when you are done. Do not soak it or use water on the motor end. Reattach the head by sliding it back into place and locking the clips or pressing until you hear a click.

Check and clear the air pathway

Blockages in the tube that connects the head to the bin will kill suction. Hold the main tube up to a light and look through it. If you see dust buildup or a blockage, straighten a wire coat hanger into a long rod and gently push it through the tube to dislodge the clog. Work slowly so you do not puncture the tube.

Also check where the head connects to the tube and where the tube connects to the bin. These joints often trap hair and dust. Twist or unclip these connections (your manual will show how) and clear any debris by hand or with a cloth. Reassemble and make sure everything clicks or twists firmly into place.

Wash the bin and dry all parts thoroughly

The bin itself can trap dust and odors. Once a month, fill a sink with warm soapy water and submerge the bin. Use a soft brush or cloth to scrub the inside and outside, paying attention to corners and the bottom. Rinse it well under running water and shake out excess water. Stand it upright on a clean towel and let it air-dry completely—at least two hours—before putting it back on the machine. Any moisture left inside can cause mold or electrical problems.

While the bin dries, wipe down the motor head (the part that attaches to the bin) with a dry cloth. Do not rinse the motor head with water. Check that all seals and gaskets are clean and free of dust. These rubber rings help the bin seal properly, so a clogged seal will reduce suction.

Replace the filter on schedule

Dyson filters wear out and cannot be cleaned forever. Most filters last about 12 months of regular use. If your filter looks gray or clogged even after rinsing, or if suction drops despite a clean bin and brush bar, it is time to replace it. Dyson sells replacement filters for each model—check your manual or the Dyson website to find the correct part number for your machine.

To install a new filter, twist off the plastic cover on top of the machine, lift out the old filter, and drop the new one in. Make sure it sits flat and fully inside the cover. Twist the cover clockwise until it is snug. Do not overtighten. Run the vacuum for a few seconds to make sure suction returns to normal.

Inspect the head and hose for cracks or damage

Every few months, look at the plastic head, hose, and bin for cracks, splits, or loose seams. Even a small crack will let air leak in and ruin suction. If you find damage, you may be able to seal it temporarily with waterproof tape, but a cracked head or hose usually needs to be replaced. Check the Dyson website or your manual for replacement parts.

Also check that the hose is not kinked or pinched where it connects to the bin. A bent hose can block airflow just as much as a clog. Straighten it gently and make sure it sits in a natural curve when the vacuum is in use.

Store your vacuum in a dry place

After cleaning, store the vacuum upright in a dry closet or garage. Do not leave it in a damp basement or outdoors, where moisture can damage the motor and filter. Make sure the filter is completely dry before storing. If you will not use the vacuum for more than a month, empty the bin and rinse the filter one more time before putting it away.

Proper storage extends the life of your machine and keeps it ready to use whenever you need it. A vacuum stored in humid conditions may develop mold on the filter or corrosion inside the motor, both of which are difficult and costly to repair.

Frequently Asked Questions

How often should I clean my Dyson upright?

Empty the bin and rinse the filter after every use or at least once a week. Clean the brush bar every three months or whenever you see hair wrapped around it. Wash the bin monthly and replace the filter every 12 months. More frequent cleaning keeps suction strong and extends the life of the machine.

Can I wash the filter in the dishwasher?

No. Always rinse the filter by hand under cool running water. Hot water and dishwasher detergent can damage the filter material and the adhesive that holds it together. Air-dry it completely before reinstalling.

What should I do if suction is still weak after cleaning everything?

Check that the bin is fully seated on the motor head and locked in place. Make sure the head is fully attached to the tube and the tube is fully attached to the bin—loose connections leak air. If all connections are tight and the filter is clean and dry, the filter may be worn out and need replacement.

Is it normal for the filter to look gray?

A little gray dust on the filter is normal, but if it looks completely gray or clogged even after rinsing, it has reached the end of its life. Replace it with a new filter. A clogged filter reduces suction and makes the motor work harder.

Can I use my Dyson while the filter is drying?

No. Never run the vacuum without a dry filter installed. A wet filter will not trap dust properly and can damage the motor. Always wait until the filter is completely dry—at least four hours—before using the machine again.
