Clean your Bissell vacuum every month to keep it running at full power
A Bissell vacuum loses suction and performance when dust clogs the filters, brush roll, and air pathways. Regular cleaning takes about 15 to 20 minutes and prevents the motor from working harder than it needs to. Most Bissell models use the same basic cleaning steps, though uprights and carpet cleaners have slightly different parts to reach.
The most important maintenance task is washing or replacing the filter every 30 days of use. A clogged filter cuts suction in half and forces the motor to overheat. After that, clear the brush roll of hair and fibers, empty the dust cup before it reaches the fill line, and wipe down the air pathways where dust accumulates. You do not need special tools—a soft brush, warm water, and a dry cloth are enough.
Key Takeaways
- Wash the main filter under warm running water every 30 days of use; let it dry completely (at least 24 hours) before reinstalling it.
- Clear the brush roll of hair and string by cutting away fibers with scissors, then spin it by hand to check for blockages.
- Empty the dust cup when it reaches the fill line, not when it is completely full, to maintain suction.
- Check the air intake opening and hose for clogs by holding them up to a light source and clearing any visible blockages.
How to remove and clean the filter
The filter is the first place dust builds up. On most Bissell uprights, the filter sits on top of the dust cup or inside the main body. Locate the filter release button or latch (usually marked on the machine) and press it to pop the filter out. On carpet cleaners, the filter may be a cartridge that twists counterclockwise to remove.
Hold the filter over a trash can and tap it gently to shake out loose dust. Then rinse it under warm running water, holding it so water flows from top to bottom—never push water upward through the filter material, as this can damage the fibers. Use your fingers to gently rub away stubborn dust, but do not scrub hard or squeeze the filter. Let it air-dry completely in a warm, dry place for at least 24 hours before putting it back in. A damp filter will reduce suction and can cause mold growth inside the machine.
Clear the brush roll and check for blockages
Hair and string wrap around the brush roll and slow it down or stop it completely. Flip the vacuum upside down on a flat surface and look at the brush roll underneath. Use scissors to cut away any hair or fibers wrapped around it, working from one end to the other. Pull the cut pieces away with your fingers or tweezers.
After clearing the brush roll, spin it by hand to make sure it turns freely. If it still feels stiff or does not spin easily, there may be a blockage inside the machine. Check the hose and air intake opening (see the next section) before reassembling. On some Bissell models, the brush roll can be removed by pressing a release button on each end—if yours has this feature, you can take it out completely to clean the area underneath.
Empty the dust cup and check the air pathways
Empty the dust cup when it reaches the fill line, not when it is completely full. A full cup blocks airflow and kills suction. Press the release button or latch to detach the cup from the main body, then hold it over a trash can and press the bottom door or dump button to empty it. Tap the sides to shake out stubborn dust, then wipe the inside with a dry cloth.
While the cup is off, look inside the main body where the cup connects. You will see an air intake opening—wipe away any dust or debris with a cloth. Check the hose by holding it up to a light and looking through it. If you see a blockage, push a broom handle or plumbing snake through gently to clear it. Do not use sharp objects that could puncture the hose. Reattach the dust cup firmly until you hear or feel it click into place.
Clean the hose and attachments
The hose can clog with dust, pet hair, or debris, especially if you use the upholstery tool or crevice attachment. Detach the hose from the main body by twisting or pressing the release button, depending on your model. Hold it up to a light and look through both ends. If you see a blockage, use a broom handle or straightened wire coat hanger to push it through gently.
Rinse the hose under warm running water, letting water flow through from both directions. Shake out excess water and hang it vertically to drain and dry completely before reattaching. Wipe down any attachments (brush heads, crevice tools, upholstery brushes) with a damp cloth and let them air-dry. Do not soak attachments in water unless the manual says it is safe to do so.
Check the seals and connections
Loose seals and connections let air leak out, which kills suction even if the filter is clean. After reassembling the dust cup, make sure it clicks firmly into place. Look for any visible cracks or damage to the cup or the connection points. If you see cracks, the cup may need to be replaced—contact Bissell customer service for a replacement part.
Check where the hose connects to the main body and where the handle connects to the upright. These connections should be tight and free of cracks. If a connection feels loose, twist it gently to tighten it. If you see cracks in the plastic, the part may need to be replaced. Bissell sells replacement parts online and through retailers, and the part number is usually printed on the machine or in the manual.
How often to replace filters and parts
The main filter should be washed every 30 days of use, but it will eventually wear out and need to be replaced. If the filter looks discolored, has a strong smell, or does not improve suction after washing and drying, it is time for a new one. Replacement filters cost between $15 and $40 depending on the model. Check your manual or the Bissell website to find the correct filter number for your machine.
The brush roll typically lasts 6 to 12 months of regular use before the bristles wear down or the roll stops spinning smoothly. If the brush roll is damaged or will not spin freely after clearing blockages, it can be replaced for $20 to $50. Pre-motor filters (smaller filters inside the machine that protect the motor) should also be checked monthly and replaced yearly. Keeping a spare filter on hand means you can wash one while the other dries.
Frequently Asked Questions
Can I use my vacuum while the filter is drying?
No. Running the vacuum without a filter or with a damp filter will damage the motor and void the warranty. Always wait until the filter is completely dry (at least 24 hours) before using the machine. If you need to vacuum right away, buy a spare filter so you can rotate between them.
What should I do if suction is still weak after cleaning?
Check the dust cup, filter, hose, and brush roll again—one of these is usually the culprit. Make sure the filter is completely dry and installed correctly. If the brush roll still does not spin freely, there may be a blockage deeper inside the machine. Consult your manual or contact Bissell support for help troubleshooting your specific model.
Is it safe to wash the filter in a dishwasher?
No. Dishwashers use hot water and harsh detergents that can damage the filter material. Always wash filters by hand under warm running water only. Do not use soap, bleach, or cleaning chemicals.
How do I know if the brush roll needs to be replaced?
If the bristles look worn down, frayed, or bent, or if the roll will not spin smoothly after you clear away hair and blockages, it is time to replace it. A worn brush roll will not pick up dirt as well, even if suction is strong.
Can I use my Bissell in the rain or on wet carpet?
No. Wet conditions can damage the motor and electrical parts. Use your Bissell only on dry surfaces indoors. If you need to clean wet carpet, use a wet-dry vacuum designed for that purpose instead.
