Empty the Bin and Wash the Filter First
Start by emptying the bin after every use or when the red line appears on the side. Press the release button near the handle, hold the bin over a trash can, and press the button at the bottom to eject the dirt. Do this outside or over a bin — the dust cloud is real.
Next, remove the filter. On most Dyson cordless models, the filter sits on top of the main unit. Twist it counterclockwise and pull straight up. Tap it gently over a trash can to dislodge loose dust, then rinse it under cool running water. Do not use hot water or soap — just water. Squeeze gently while rinsing until the water runs clear. Let it air-dry completely (at least 4 hours, ideally overnight) before putting it back. A wet filter will damage the motor.
Key Takeaways
- Empty the bin and rinse the filter after every use to keep suction strong and prevent motor damage.
- The filter must air-dry completely before you reinstall it, which takes at least 4 hours.
- Clean the brush bar monthly by removing hair and debris wrapped around the bristles.
- Check the air pathways and cyclone for blockages if suction drops suddenly, since clogs are the most common reason for power loss.
- Charge the battery fully before first use and avoid letting it drain completely on a regular basis.
Clean the Brush Bar and Remove Tangled Hair
Hair wraps around the brush bar constantly and reduces suction. Remove the brush bar by pressing the release tabs on either side of the head and sliding it out. Use scissors or a seam ripper to cut away hair, lint, and string wrapped around the bristles. Work along the entire length — the ends collect as much as the middle.
Once you have removed the visible hair, rinse the brush bar under cool water to flush out dust trapped in the bristles. Let it dry before sliding it back in until you hear it click. Do this monthly, or more often if you have pets or long hair in the household.
Check for Blockages in the Air Pathway
If suction drops suddenly, a blockage is usually the cause. Start by looking down the main tube from the head — hold it up to a light and look for clogs. Remove any visible debris with your fingers or a straightened wire coat hanger. Push gently from both ends if something is stuck in the middle.
Next, check the cyclone (the clear chamber above the bin). Unclip it by pressing the release button and pull it straight down. Look inside for dust buildup or debris. Rinse it under cool water and let it dry. Also inspect the connection points where the head, tube, and main unit join — dust can pack into these seams. Wipe them with a dry cloth.
Clean the Bin and Cyclone Regularly
The bin itself collects fine dust that reduces airflow. Empty it after each use, then once a week, rinse the inside under cool water. Use a soft brush or cloth to wipe the walls. Let it dry completely before snapping it back on.
The cyclone (the clear plastic chamber) also needs regular cleaning. Unclip it and rinse under cool water, rubbing the inside gently with your fingers to break up dust buildup. Pay attention to the small vanes inside — dust sticks there. Dry it thoroughly before reattaching.
Maintain the Battery and Charging Dock
Charge the vacuum fully before using it for the first time. The battery performs best when you avoid letting it drain completely on a regular basis — charge it when you reach about 20 percent power. Store the vacuum on the charging dock between uses so it is ready when you need it.
If the battery stops holding a charge after several years, it will need replacement. Dyson sells replacement batteries separately. Keep the charging contacts on both the dock and the vacuum clean by wiping them with a dry cloth every few months.
Inspect the Head and Seals for Wear
Over time, the rubber seals around the head and connections can crack or shrink, which lets air escape and kills suction. Look at the rubber gasket where the head connects to the tube — it should be smooth and pliable, not cracked or hard. If it looks damaged, you can order a replacement seal from Dyson.
Also check the bristles on the brush bar. If they are worn down to half their original height, the bar is not cleaning as well and should be replaced. Dyson sells replacement brush bars, and swapping one takes less than a minute.
Store Your Vacuum Properly
Store the vacuum on its charging dock in a dry place. Do not leave it in a damp garage or basement, as moisture can damage the motor and battery. Keep the filter dry and the bin empty when storing for more than a few days.
If you are storing the vacuum for the winter or a long period, charge the battery to about 50 percent and store it in a cool, dry place. Leaving it fully charged or completely drained for months can shorten battery life.
Frequently Asked Questions
Can I wash the filter with soap?
No. Use only cool water with no soap or detergent. Soap leaves a residue that clogs the filter and reduces suction. Rinse until the water runs clear, then air-dry completely before reinstalling.
How often should I clean the brush bar?
Check it after every use if you have pets or long hair. Remove visible hair and lint. Do a full rinse and cleaning at least once a month, or more often if hair wraps around it frequently.
What do I do if suction is still weak after cleaning the filter and bin?
Check the main tube and cyclone for blockages. Look down the tube toward a light and remove any debris. Rinse the cyclone and inspect all connection points where parts join. If suction is still low after that, the brush bar bristles may be worn down or a seal may be damaged.
Is it normal for the filter to get clogged quickly?
If you are emptying the bin regularly and rinsing the filter after each use, it should not clog quickly. If it does, you may be vacuuming very fine dust (like drywall or flour) that needs more frequent filter cleaning, or the bin may not be sealing properly.
Can I use the vacuum while the filter is drying?
No. A wet or damp filter will damage the motor. Always wait until the filter is completely dry — at least 4 hours — before using the vacuum. Keep a second filter on hand so you can rotate them.
