Clean your Dyson Animal after every use to keep suction strong

A Dyson Animal vacuum loses suction when pet hair and dust block the filter, bin, and airways—sometimes within a few uses if you have shedding pets. Cleaning takes about 15 minutes and requires no tools beyond what comes in the box. The steps are the same whether you own a upright, cordless, or handheld Animal model: empty the bin, rinse the filter, clear the brush bar, and wipe the airways.

Most clogs happen in the filter or brush bar, not the motor. If you clean these two parts weekly and empty the bin after each session, your vacuum will pull as hard as it did on day one. Dyson filters wear out after about 12 months of regular use and cost $20 to $40 to replace, depending on your model.

Key Takeaways

  • Empty the bin after every use and rinse the filter under cold running water once a week to prevent suction loss.
  • The brush bar clogs with pet hair wrapped around the roller—clear it by hand or with scissors after each use on carpeted areas.
  • Let the filter air-dry completely (at least 24 hours) before putting it back in the vacuum to avoid mold and motor damage.
  • Check the clear tube and cyclone for blockages by holding them up to light and pushing debris out with your finger or a straightened coat hanger.

Empty the bin and rinse the filter every week

Press the bin release button on the side or back of your vacuum (the exact location varies by model) and pull the bin straight down. Hold it over a trash can and press the bottom release catch to dump the contents. Tap the bin against the trash can rim to shake loose any clinging dust.

Unclip the filter from the top or side of the bin—it looks like a tall, pleated cartridge. Rinse it under cold running water, holding it so water flows from top to bottom through the pleats. Do not use hot water or soap. Squeeze gently as you rinse; do not wring or twist the filter. If the filter is very dirty, soak it in cold water for 30 minutes, then rinse again. Stand it upright on a towel and let it air-dry for at least 24 hours before reinstalling. A damp filter will damage the motor and void your warranty.

Clear pet hair from the brush bar after each use

The brush bar is the spinning roller at the bottom of the vacuum head. Pet hair wraps around it in a spiral, choking off the bristles and killing suction within a few sessions. Flip the vacuum head over and look at the roller from underneath. You will see hair wound tightly around it.

Use your fingers to pull away loose hair, then use small scissors or a seam ripper to cut through the wrapped strands. Work along the entire length of the roller. This takes two to three minutes. Once you have removed the bulk of the hair, run your finger along the roller to feel for any remaining fibers. If your Dyson has a removable brush bar (some cordless models do), unclip it and clean it in the sink under running water, then dry it before snapping it back in.

Check the clear tube and cyclone for blockages

The clear plastic tube that connects the head to the bin can trap hair and dust, especially if you vacuum long pet hair. Hold the tube up to a light source and look through it. If you see a blockage, push it out with your finger or straighten a wire coat hanger and feed it through from both ends.

The cyclone—the cone-shaped part on top of the bin—can also clog. Remove it by twisting it counterclockwise and lifting it off. Look inside the opening where it connects to the bin. If you see dust or hair packed in there, use your finger or a dry cloth to wipe it out. Rinse the cyclone under cold water if needed, dry it completely, and twist it back on clockwise until it clicks.

Wipe down the airways and check seals

Dust and pet dander settle inside the plastic airways where the bin meets the head and where the cyclone connects. Use a dry cloth or paper towel to wipe the inside surfaces of the bin opening and the bottom of the cyclone. Pay special attention to the rubber seals—they should be clean and flexible so air does not leak.

If you see cracks in the rubber seals or if the seal no longer sits flush against the plastic, the seal may need replacement. Dyson sells replacement seals for most Animal models for $10 to $20. A leaking seal will reduce suction even if the filter and brush bar are clean.

Replace the filter when rinsing no longer restores suction

After 12 months of regular use, the filter material becomes clogged with fine dust that rinsing cannot remove. You will notice suction dropping even right after you clean the filter. This is the sign to order a replacement.

Find your model number on the back or underside of the vacuum. Go to the Dyson website or call their customer service line to order the correct filter for your model. Installation takes 30 seconds: unclip the old filter, clip the new one in, and you are done. Keep a spare filter on hand so you can swap it in while the other dries after rinsing.

Maintain the battery and motor on cordless models

If you own a cordless Dyson Animal, the battery drains faster when the filter is clogged because the motor works harder to pull air. Cleaning the filter weekly will extend battery life by 20 to 30 percent. Charge the vacuum on its dock after each use, even if you only ran it for a few minutes.

Do not store the vacuum with a wet filter installed, and do not leave it on the dock with a clogged filter for days at a time. The motor will strain and may overheat. If the vacuum shuts off mid-session, empty the bin and rinse the filter before charging again.

Frequently Asked Questions

Can I wash the filter in the dishwasher?

No. The dishwasher's heat and detergent will damage the filter material and void your warranty. Rinse it by hand under cold water only. If it is very dirty, soak it in cold water for 30 minutes first.

How do I know if the brush bar is broken?

The brush bar should spin freely when you flip the vacuum over and turn it on. If it does not spin or spins unevenly, the motor may be damaged or the bar may be bent. Stop using the vacuum and contact Dyson support, as this usually requires professional repair.

What if the filter still smells bad after rinsing?

Odor means mold is growing inside the filter. Soak it in cold water for one hour, rinse thoroughly, and air-dry in direct sunlight for 24 hours. If the smell returns, replace the filter—mold can damage the motor and your home's air quality.

Do I need to clean the head attachment separately?

Yes. Remove the head from the wand by twisting it counterclockwise. Rinse it under cold water and wipe the bristles with a cloth. Let it air-dry before reattaching. This prevents hair and dust from building up inside the connection.

How often should I replace the brush bar?

The brush bar lasts two to three years with weekly cleaning. If the bristles are matted down, bent, or missing, or if the roller no longer spins smoothly, it is time to replace it. Dyson sells replacement bars for $30 to $60 depending on your model.
