Empty the Bin and Rinse the Filter First
Start by unplugging the vacuum from the wall. Press the bin release button — usually located near the handle or on the side of the machine — and pull the bin straight down and away from the body. Empty all dust and debris into a trash can, then tap the bin gently against the inside of the can to dislodge stubborn particles.
Next, locate the filter. On most upright Dysons, it sits on top of the machine or inside the bin compartment. Remove it by twisting counterclockwise or pressing a release tab, depending on your model. Hold the filter over a trash can and tap it firmly to shake out loose dust. Then rinse it under cool running water, holding it with the pleats facing downward so water flows away from the motor housing. Let the filter air-dry completely — at least 24 hours — before reinstalling it. A wet filter will damage the motor.
Key Takeaways
- Empty the bin after every use and rinse the filter monthly under cool water, letting it dry fully before reinstalling.
- Clear the brush bar of hair and debris by removing it from the underside of the machine and wiping it clean with a damp cloth.
- Check the hose and intake ports for blockages by holding them up to a light source and pushing a broom handle through if needed.
- Replace the filter every 12 months or sooner if it looks visibly clogged, and replace the brush bar every 12 to 18 months depending on use.
- Store the vacuum upright in a dry location and avoid using it on wet surfaces or in damp basements, which can damage internal parts.
Clean the Brush Bar and Remove Tangled Hair
The brush bar — the spinning roller at the bottom of the vacuum head — collects hair, string, and fibers that reduce suction and wear out the motor. Flip the vacuum upside down on a flat surface and locate the brush bar access panel. Most Dysons have a release button or latch on either end of the panel; press or slide it to remove the panel and expose the brush bar.
Grab the brush bar and pull it straight out of its housing. Use scissors or a seam ripper to cut away any hair wrapped around it, working from one end to the other. Wipe the entire bar with a damp cloth to remove dust and debris. Check the two bearing caps on either end — small plastic pieces that hold the bar in place — and make sure they are not cracked or loose. Slide the bar back in until you hear or feel it click, then replace the access panel.
Clear Blockages in the Hose and Air Pathways
A blocked hose or intake port will kill suction even if the bin and filter are clean. Detach the hose from the main body by twisting it counterclockwise or pressing a release button. Hold the hose up to a bright light and look through it. If you see dust buildup or a blockage, straighten a wire coat hanger or use a broom handle to push the clog out from one end.
Check the intake port where the hose connects to the machine. Debris often collects here. Use a flashlight to peer inside, and remove any visible blockages with your fingers or a cloth. Do the same for the port on the bin itself. Run water through the hose if it is very dirty, then shake it dry and hang it vertically to drain completely before reattaching.
Inspect and Clean the Cyclone and Bin Compartment
The cyclone — the cone-shaped part inside the bin that spins to separate dust from air — can clog with fine dust over time. Once you have emptied the bin, look inside the cyclone for a layer of dust coating the ridges. Rinse it under cool water, using your fingers or a soft brush to gently remove buildup. Do not scrub hard, as the cyclone is plastic and can crack.
Wipe the inside of the bin itself with a damp cloth to remove dust residue. Pay attention to the corners and seams where dust settles. Dry everything thoroughly before reassembling. A damp bin can cause mold and odors, and moisture inside the machine can damage the motor.
Replace Filters and Brush Bars on Schedule
Dyson filters are not designed to last forever. Most upright models need a new filter every 12 months with regular use, or sooner if you have pets or allergies and vacuum frequently. A clogged filter that cannot be cleaned will reduce suction and force the motor to work harder, shortening its lifespan. Replacement filters are sold by Dyson and third-party retailers; check your model number before ordering.
The brush bar typically lasts 12 to 18 months depending on how often you vacuum and how much hair and debris it encounters. If the bristles are matted, broken, or no longer spin freely, it is time to replace it. Worn brush bars do not pick up debris as well and can damage the floor. Replacement bars are available from the same sources as filters.
Store Your Vacuum Properly to Extend Its Life
Keep your Dyson in a dry, temperature-controlled space — not a damp basement, garage, or outdoor shed. Moisture can corrode the motor and electrical connections. Store it upright so the brush bar does not sit flat on the floor for long periods, which can bend the bristles permanently.
Never use your upright Dyson on wet carpet, standing water, or damp floors. Water can enter the motor housing and cause electrical damage or mold growth inside the machine. If you accidentally vacuum up water, unplug the machine when ready and let it dry for at least 48 hours before using it again. Do not attempt to dry it with heat or a hair dryer, as this can damage internal components.
Troubleshoot Loss of Suction Before Assuming the Motor Is Failing
If your Dyson suddenly loses suction, the problem is almost always a clogged filter, full bin, or blocked hose — not a broken motor. Work through these checks in order: empty the bin, rinse the filter, clear the hose, and check the brush bar for tangles. Most of the time, one of these steps will restore full suction.
If suction is still weak after cleaning everything, remove the filter and run the vacuum for a few seconds without it. If suction returns to normal, the filter is the culprit and needs replacement. If suction remains weak, the motor may have an internal issue and the machine may need professional repair or replacement, depending on warranty coverage.
Frequently Asked Questions
Can I wash the filter in a dishwasher or washing machine?
No. Dishwashers and washing machines use hot water and detergent, both of which can damage the filter material and the motor when you reinstall it. Always rinse under cool running water by hand, and never use soap or cleaning products.
How often should I empty the bin?
Empty the bin after every use, or whenever it reaches the fill line marked on the side. A full bin reduces suction and forces the motor to work harder. On high-pile carpet or with pets, you may need to empty it mid-cleaning.
What if my vacuum still has no suction after I clean the filter and hose?
Check the brush bar for hair and debris, and make sure the filter is completely dry before reinstalling it. If those are clear, remove the filter entirely and test the suction. If suction returns without the filter, the filter needs replacement. If it remains weak, contact Dyson support or check your warranty.
Is it normal for the filter to look gray or discolored after rinsing?
Yes. The filter traps fine dust that does not always rinse away completely. As long as water flows through it easily and it dries fully, it is fine to use. If water pools on the surface instead of flowing through, the filter is too clogged and needs replacement.
Can I use my upright Dyson on hardwood or tile floors?
Yes, but use the hard-floor setting if your model has one, or turn off the brush bar to avoid scratching. The brush bar is designed for carpet and can leave marks on delicate surfaces. Always test a small, hidden area first.
