You spent six hundred bucks on a vacuum. Maybe more. It’s that sleek, purple-and-grey beast that lives in your utility closet, and for the first six months, it felt like it could suck the soul out of a carpet. But lately? It’s sounding a bit wheezy. Maybe that "airway blocked" light is flashing rhythmically like a techno club, or perhaps it just smells like a wet dog every time you trigger the power. Honestly, most people wait until the machine literally stops breathing before they wonder how to clean Dyson filters and bins. By then, you’re basically suffocating the digital motor.
Dyson machines are engineering marvels, but they are incredibly finicky about airflow. James Dyson, the man himself, built over 5,000 prototypes of his cyclonic vacuum because he was obsessed with the idea that bags clog and lose suction. The irony? If you don't clean your Dyson, the "bagless" cyclones get packed with fine dust, and you're right back where you started in 1991.
Cleaning these things isn't just about emptying the bin. It's about maintenance that keeps that $700 investment from ending up in a landfill. If you’ve noticed your battery life dipping on a V11 or V15, it might not be a bad battery. It’s often just the motor working overtime to pull air through a wall of microscopic silt.
The Filter Fiasco: Why Cold Water Is Your Best Friend
Most people mess this up. They use soap. Or they try to dry it with a hairdryer. Don't.
Your Dyson filter—whether it’s the long stick filter on a V10 or the HEPA assembly on the newer Gen5—is a pleated piece of high-efficiency material. When you learn how to clean Dyson components, the filter is the most critical variable. You need to wash it with cold, plain water. No "fresh scent" dish soap. No bleach. Just tap water.

Tap the filter against the side of the sink before you wet it. You’ll be disgusted by the amount of grey flour that falls out. That's the stuff that bypasses the cyclones. Once you’ve tapped it out, run water through the open end until it runs clear. Give it a firm squeeze. Not a wring—don't twist it like a wet towel—but a firm squish to get the bulk of the moisture out.
Here is the part that kills machines: patience. You must wait 24 hours. Some experts, and even Dyson's own support team in the UK, suggest 48 hours if you live in a humid climate. If you put a damp filter back into a Dyson, the moisture gets sucked into the motor. Water + 125,000 RPM digital motor = an expensive paperweight. Set it on a windowsill. Forget it exists for two days.
That Grime in the Bin
Emptying the bin is easy. Cleaning the bin is a different story.
You’ve probably seen that film of grey haze on the inside of the clear plastic. It looks ugly. To get it truly clean, you usually have to detach the bin entirely from the "cyclone" assembly. On most cordless models, there’s a small red lever or button that lets the bin slide right off the runner.
Wipe it down with a damp, lint-free cloth. Do not submerge the actual cyclone part (the big shroud with all the holes) in water. I know, it’s tempting. You see dust in those little holes and you want to dunk the whole thing in a bucket. If water gets into the upper cyclone assembly, it can get trapped in the narrow cones. Eventually, that trapped dust turns into mud, dries, and permanently blocks the airflow. Use a can of compressed air or a soft toothbrush to clear the shroud holes instead.
The Brush Bar: A Hair-Raising Experience
If you have pets, or humans with long hair in your house, your brush bar is currently a crime scene.
Newer models like the V15 have "anti-tangle" combs, but they aren't perfect. To properly maintain the machine, you need to pop the end cap off the cleaner head. Usually, you can use a coin to twist the lock. Slide the roller out.
Don't just pull at the hair. Get a pair of sewing scissors or a seam ripper. Cut a straight line across the tangled hair along the groove of the roller. It’ll peel off like a carpet. While you have the roller out, look into the throat of the vacuum head. You’d be shocked how many "loss of suction" issues are actually just a stuck Lego or a clump of hair ties wedged in the neck of the attachment.
Specifics for the Big Ball Uprights
If you’re rocking an old-school Dyson Ball Animal 2 or 3, the process is slightly more industrial. These machines have more points of failure. Check the "U-bend" at the bottom. It’s a little clear plastic pipe that often gets clogged with heavy debris.
The upright filters are usually split into two: a pre-motor filter (the washable one) and a post-motor HEPA filter. The HEPA filter on the Ball models is often located inside the actual ball. You unscrew the side, and there it is. Dyson says these are "lifetime" filters, but "lifetime" in vacuum speak usually means about 5 to 7 years. If it looks black, replace it. It’s not worth the strain on the motor.
Smells and Sanitization
Let's talk about the stink. If your vacuum smells like a locker room, it’s because bacteria is growing on the organic matter (skin cells, food bits) trapped in the cyclones.
A pro tip that isn't in the manual: dry bicarbonate of soda. Sprinkle some on your carpet, vacuum it up, and let it sit in the bin for an hour before emptying. It helps neutralize the odor without using liquids that could damage the electronics.
Never spray Febreze or perfume directly into the intake. The oils in those sprays will coat the filters and act like glue for dust, causing the vacuum to clog twice as fast.
Actionable Maintenance Checklist
Maintaining your Dyson doesn't have to be a Saturday-long project.
- Monthly: Wash the filter in cold water and let it air dry for 24-48 hours.
- Weekly: Check the brush bar for hair wraps and clear them before they stress the motor belt.
- Every Bin Empty: Give the cyclone shroud a quick tap to knock loose the "clinging" dust.
- Annually: Inspect the seals. If the rubber gaskets around the bin look cracked or flattened, you're losing suction. Replacement gaskets are cheap on third-party sites and can make a five-year-old machine feel brand new.
If you follow these steps, your Dyson will actually last the decade it was designed for. Most "broken" Dysons on Facebook Marketplace are just dirty machines owned by people who didn't realize they had to wash the filters. Don't be that person. Clean the airway, dry the filters thoroughly, and keep the brush bars spinning freely.
The most important takeaway? If the machine sounds like it's "pulsing" (revving up and down), it is literally gasping for air. Stop using it immediately and check for a blockage in the wand or a filthy filter. Ignoring that sound is the fastest way to burn out the PCB. Keep it clear, keep it dry, and it'll keep your floors spotless.
