Empty the dirt tank or change the bag before every use
A full dirt tank or bag cuts suction and makes your vacuum work harder than it needs to. On bagless Bissell models, the dirt tank usually has a release button or latch on the side — press it, twist, or slide to detach. Hold it over a trash can and tap the bottom or sides to loosen the dirt, then empty it completely. On bagged models, follow the manual to locate the bag compartment, slide out the old bag, and insert a new one of the correct size for your model.
Check the tank or bag before every cleaning session. A vacuum that loses suction mid-job is almost always full, not broken. Emptying it takes less than a minute and prevents dust from clogging the motor.
Key Takeaways
- Empty the dirt tank or replace the bag before each use to maintain suction and protect the motor from dust buildup.
- Rinse the filter under cool running water every month, or more often if you have pets or allergies — a clogged filter is the most common reason for lost suction.
- Check the brush roll for hair and string wrapped around it at least once a month, and cut away any tangles with scissors.
- Wipe down the exterior with a damp cloth and inspect the hose and nozzle for blockages if suction drops suddenly.
- Replace filters and brush rolls according to your model's manual, usually every 6 to 12 months depending on use.
Rinse the filter monthly under cool water
The filter traps fine dust and allergens. Over time it clogs, and a clogged filter is the number-one reason Bissell vacuums lose suction. Most Bissell models have a cylindrical or cartridge filter located inside the tank or behind a panel on the back or side. Check your manual for the exact location on your model.
Remove the filter and hold it under cool running water. Let water flow through it from the inside out — do not spray it from the outside in, as that pushes dirt deeper into the material. Gently rub the pleats with your fingers to loosen trapped dust. Let it air-dry completely before putting it back in — a wet filter can damage the motor. If the filter is visibly torn or stained dark gray even after rinsing, it is time to replace it.
Rinse the filter every month if you vacuum regularly, or every two weeks if you have pets or someone with allergies in the home. A clean filter keeps suction strong and extends the life of your vacuum.
Clear hair and string from the brush roll
The brush roll (the spinning brush at the bottom of the vacuum head) picks up hair, string, and fibers that wrap around it and slow it down. Over time, a clogged brush roll can stop spinning altogether. Check it at least once a month, or every two weeks if you have long hair or pets.
Unplug the vacuum and flip it over so you can see the brush roll. Look for hair, string, or thread wound tightly around it. Use scissors or a seam ripper to cut away the tangles — work carefully so you do not cut the bristles themselves. Once the roll spins freely by hand, flip the vacuum back over and plug it in. If the brush roll does not spin after you clear it, the motor may be damaged and the vacuum will need service.
Check the hose and nozzle for clogs
If suction drops suddenly even after you empty the tank and rinse the filter, something is blocking the airflow. Unplug the vacuum and detach the hose from both ends. Hold it up to a light and look through it — you should see light on the other side. If you see a blockage, use a broom handle or plumbing snake to push it out gently from one end.
Check the nozzle (the attachment head) as well. Remove any visible hair or debris from the intake opening. If the nozzle has small holes or vents, use a toothpick or thin wire to clear them. Reattach the hose and nozzle, plug in the vacuum, and test the suction. A clear hose and nozzle restore full suction when ready.
Wipe the exterior and check seals
Dust and dirt accumulate on the outside of your vacuum and can work their way into the motor. Once a month, unplug the vacuum and wipe down the tank, handle, and hose with a damp cloth. Pay attention to seams and joints where dirt collects. Let everything dry before plugging the vacuum back in.
While you are cleaning the exterior, check the rubber seals where the tank attaches to the motor housing. If a seal is cracked or loose, air leaks out and suction drops. Seals are inexpensive to replace and usually snap in or out without tools — check your manual for the part number and order a replacement if needed.
Replace the filter and brush roll on schedule
Rinsing the filter keeps it working longer, but filters wear out and eventually need replacement. Most Bissell filters last 6 to 12 months depending on how often you vacuum and whether you have pets. Brush rolls typically last 12 to 18 months. Check your manual for the recommended replacement interval for your specific model.
Order replacement parts directly from Bissell or from a retailer that carries your model. Keep the model number handy — it is usually printed on a label on the back or bottom of the vacuum. Replacing these parts yourself takes a few minutes and costs far less than a repair visit. A new filter and brush roll restore the vacuum to nearly new performance.
Store your vacuum in a dry place
Moisture and heat shorten the life of the motor and electrical components. Store your Bissell in a closet, garage, or utility room where it stays dry and away from direct sunlight. Do not store it with the tank full or the filter damp — always empty the tank and let the filter air-dry before putting the vacuum away.
Coil the cord loosely around the vacuum or use a cord wrap to prevent kinks. If you store the vacuum for more than a few weeks, empty the tank again before the next use, as dust can settle and compact inside.
Frequently Asked Questions
Can I wash the filter in the dishwasher or washing machine?
No. Hot water and detergent can damage the filter material and the adhesive that holds it together. Always rinse under cool running water by hand and let it air-dry completely. Check your manual — some Bissell filters say "do not wash" at all, and rinsing is not recommended for those models.
What should I do if the vacuum still has no suction after I clean the filter and brush roll?
Check the hose and nozzle for blockages, and make sure the tank is completely empty. If suction is still weak, the motor may be failing or a seal may be broken. Contact Bissell customer service with your model number — they can walk you through additional troubleshooting steps or discuss repair options.
How often should I replace the filter if I have a pet?
Pet hair clogs filters faster than regular household dust. If you have a pet, rinse the filter every two weeks and replace it every 3 to 6 months instead of the standard 6 to 12 months. Some Bissell models designed for pet hair have larger or dual filters that last longer — check your manual to see if yours is one of them.
Is it safe to use the vacuum while the filter is drying?
No. A wet or damp filter can allow dust and moisture to reach the motor and damage it. Always wait until the filter is completely dry before using the vacuum again. This usually takes 24 hours. If you need to vacuum before then, order a replacement filter so you have a spare while one is drying.
Can I use any brand of replacement filter in my Bissell?
Generic filters may fit, but Bissell filters are designed to match your model's airflow and motor specifications. Using the wrong filter can reduce suction or allow dust to bypass the filter and damage the motor. Order the filter that matches your model number — the part number is in your manual or on Bissell's website.
