Empty the bin and wash the filter every week
A Dyson pet vacuum loses suction when the bin is full or the filter is clogged—usually both happen at the same time. Empty the bin after every use or when it reaches the fill line, whichever comes first. Pet hair wraps around the filter faster than regular dust does, so you need to rinse it weekly instead of monthly.
To empty the bin, press the red release button above the handle and twist the bin counterclockwise. Tap the bottom over a trash can to dislodge compacted hair. For the filter, press the filter release button on top of the machine and pull straight up. Rinse it under cool running water—not hot, which damages the pleats. Use your fingers to gently work out trapped hair; do not use a brush or compressed air. Tap out excess water and let it air-dry completely (at least 4 hours, ideally overnight) before reinstalling.
Key Takeaways
- Empty the bin after every use and rinse the filter weekly with cool water to restore suction lost to pet hair buildup.
- The brush bar on pet models clogs with hair wrapped around the roller; cut it away with scissors every two weeks or when you see wrapped strands.
- Dyson filters take 4 to 8 hours to dry completely, so have a second filter on hand so you can clean one while using the other.
- The cyclone and air pathways collect pet hair dust that blocks airflow; tap the cyclone sharply over a trash can and wipe the intake ports with a dry cloth monthly.
- Never use hot water, compressed air, or a washing machine on any Dyson filter—these damage the pleats and void the warranty.
Cut hair wrapped around the brush bar
Pet hair wraps tightly around the brush bar roller, strangling the bristles and stopping them from spinning. You will notice the brush bar slowing down or stopping entirely, or suction dropping even after you empty the bin and clean the filter. This happens every two to four weeks with heavy pet use.
Unplug the vacuum and lay it on its side so you can see the brush bar underneath. Use small scissors or a seam ripper to cut the hair wrapped around the roller lengthwise—do not cut the bristles themselves. Work slowly and pull the cut hair away as you go. Once the roller spins freely by hand, flip the machine over and do the same on the other side. Plug it back in and run it for 10 seconds to confirm the brush bar is moving smoothly.
Tap the cyclone and clear the air pathways
The cyclone—the clear chamber where air spins to separate dust from pet hair—collects a fine layer of hair and dander that gradually blocks airflow. You cannot see this buildup easily, but it cuts suction by 20 to 30 percent over a month. Clear it monthly or whenever you notice suction dropping after you have already cleaned the filter and brush bar.
Remove the bin by pressing the red release button and twisting counterclockwise. Hold the cyclone over a trash can and tap the sides sharply with your knuckles 10 to 15 times. You will see dust and hair fall out. While the bin is off, use a dry cloth to wipe the intake ports (the openings where air enters the cyclone) and the inside of the bin itself. Do not use water here—these parts dry slowly and moisture can damage the motor. Reattach the bin and test the suction.
Soak the hose and wand in warm water
Pet hair and debris pack inside the hose and wand, especially near the connection points. A clogged hose feels like the vacuum has lost all suction even though the bin and filter are clean. Check by holding the hose up to a light and looking through it—you should see light on the other end. If you see blockages, soak and flush the hose.
Detach the hose from the machine by twisting counterclockwise. Fill a bathtub or large container with warm (not hot) water and submerge the hose for 15 to 20 minutes. Use your fingers to work out hair clogs from the outside while it soaks. Stand the hose upright in the tub and pour warm water through it from the top to flush out loosened debris. Shake out excess water and hang the hose vertically to drain and dry for at least 2 hours before reattaching. Do the same for the wand if it feels heavy or restricted.
Clean the head and attachment ports
The connection points where the hose, wand, and head attach collect hair and dust that prevents a tight seal. A loose seal lets air leak around the connection instead of pulling through the brush bar, which feels like sudden suction loss. Wipe these ports monthly or whenever you notice suction dropping in one area of the head.
Unplug the vacuum. Use a dry cloth to wipe the male connector (the part that sticks out) on the hose and wand, and the female connector (the socket) on the machine and head. If you see hair wrapped around the connector, cut it away with scissors. Check that the connections twist smoothly and feel snug when reattached. If a connection feels loose or does not twist all the way, the threads may be stripped—contact Dyson support, as this usually requires a replacement part.
Replace the filter if it stays clogged after washing
Dyson filters last 4 to 6 months with regular pet use, depending on how often you vacuum and how many pets you have. If the filter still feels clogged or suction does not return after you have washed and dried it completely, the pleats are permanently blocked and the filter needs to be replaced. Dyson sells replacement filters for pet models; the part number is printed on the old filter.
Order the correct filter for your model (V15, V12, V11, V10, or V8 pet models each use different filters) and install it by pressing it straight up into the filter housing until you hear a click. Run the vacuum for 30 seconds to seat the new filter. Suction should return when ready. Keep the old filter as a backup for future cleaning days while your primary filter dries.
Store your vacuum in a dry place between uses
Moisture trapped inside the motor housing or battery can cause mold and electrical problems, especially if you live in a humid climate or vacuum wet surfaces. Store the vacuum upright in a closet or cabinet with the door closed, not in a garage or basement where humidity builds up. Make sure the filter is completely dry before storing—a damp filter left in the machine overnight can develop mold.
If you use the vacuum outdoors or on damp surfaces, stand it upright in a well-ventilated area for 1 to 2 hours after use so moisture can evaporate from the motor and battery. Never store the vacuum while the filter is still wet or the bin is full. Empty the bin and let the filter air-dry before putting the machine away.
Frequently Asked Questions
Can I wash the Dyson filter in the washing machine?
No. The washing machine's heat and agitation damage the pleats and void the warranty. Rinse the filter by hand under cool running water only, using your fingers to gently work out trapped hair. Let it air-dry completely before reinstalling.
How do I know if the brush bar is broken?
A broken brush bar will not spin at all, even after you cut away wrapped hair and the roller moves freely by hand. If the brush bar still will not turn after you have cleared all obstructions, the motor or bearings may be damaged and you will need to contact Dyson for a replacement head.
Why does my vacuum still lose suction after I clean everything?
Check the hose for clogs by holding it up to light and looking through it. If the hose is clear, the cyclone may need tapping, or the filter may be permanently clogged and need replacement. If suction is still low after all these steps, the motor may be failing—contact Dyson support.
Do I need to buy a second filter?
It is helpful but not required. Since filters take 4 to 8 hours to dry, having a second filter lets you vacuum while one dries. If you only have one filter, empty the bin more often and vacuum less frequently so the filter has time to dry between uses.
What should I do if the hose connection is leaking air?
First, wipe both the male and female connectors with a dry cloth to remove hair and dust. Reattach and twist firmly until you feel resistance. If air still leaks, the threads may be stripped and the hose or connection piece will need to be replaced—contact Dyson with your model number.
