Knowing how to clean your Bissell vacuum is the most effective thing you can do to keep it working like new. The routine is simpler than most people expect: empty the dirt tank every few uses, rinse the washable filter once a month, and cut hair off the brush roll every couple of weeks. If you're building better home habits overall, our cleaning guides are a good place to start.
Bissell makes dozens of models — bagless uprights, cordless stick vacuums, CrossWave multi-surface cleaners, and more. The components differ from one model to the next, but the maintenance logic is consistent across all of them. A clogged filter kills suction. A tangled brush roll strains the motor. A full dirt tank is usually the first place odors come from. None of these problems are hard to fix once you know what to look for.
This guide walks through each part of the process in a logical order: what signs tell you it's time to clean, what supplies you need, what mistakes to avoid, how often to tackle each task, and whether the effort actually pays off. By the end, you'll have a practical routine you can follow without overthinking it.

Your vacuum won't send you a notification when it needs attention, but it gives clear signals if you know what to look for. Most people wait until something goes noticeably wrong before cleaning, but catching the early warning signs means less strain on the machine and consistently better results on your floors.
If your Bissell is leaving visible debris behind after a first pass — or struggling to pick up pet hair it used to grab effortlessly — reduced suction is almost always the culprit. And reduced suction almost always traces back to one of three things: a clogged filter, a full dirt tank, or a partial blockage in the hose. These are not mechanical failures. They are maintenance issues, and they're fixable in minutes.
A partially blocked filter cuts airflow significantly, even when the filter doesn't look especially dirty from the outside. Dust compresses and cakes onto the filter surface over time, blocking the microscopic pores that air passes through. The motor then works harder to compensate, which shortens its overall lifespan. According to the U.S. Environmental Protection Agency, indoor air can be two to five times more polluted than outdoor air — and a vacuum running with a dirty filter can push fine particles back into the room rather than trapping them. If allergies are a concern in your home, our guide on the best vacuums for allergy sufferers explains which features matter most for capturing fine particles.
A vacuum that leaves a stale or musty smell in its wake isn't cleaning your home — it's spreading something around. The most common source of vacuum odors is the dirt tank, especially in households with pets. Dander, hair, and fine debris break down inside the tank over time and produce that familiar unpleasant smell. The filter is usually the second culprit, particularly if it was ever reinstalled while still slightly damp.
The reassuring part is that a thorough clean of the dirt tank and filter resolves most odor problems within one cleaning session. For persistent smells that survive a standard clean, our guide on how to remove odor from a vacuum cleaner covers additional steps including deodorizing treatments and filter replacement timelines.
One of the best things about Bissell maintenance is that it doesn't require specialty products or a trip to the hardware store. Everything you need is almost certainly already in your home, and the process is straightforward enough that you can do it while watching TV or listening to a podcast.
Before taking anything apart, gather your supplies so you're not hunting around mid-clean. Here's what you'll want on hand:
That's genuinely all you need for most Bissell models. The process is intentionally low-tech — these machines are built to be maintained without special equipment.
Compressed air in a can (the kind sold for cleaning keyboards and electronics) is the most useful optional tool you can add to your kit. It blows dust out of motor vents and housing crevices that a brush can't reach. A small flashlight helps you spot blockages inside the hose and wand — debris tends to accumulate at bends and joints, and these spots are easy to miss by sight alone from the entry points.
If your Bissell uses a washable HEPA filter (common on CrossWave and ProHeat models), keeping a spare filter on hand is worth the small investment. It means you're never waiting 24 hours for one to dry before you can vacuum again, which makes it much easier to stay consistent with your maintenance routine rather than putting it off because the timing is inconvenient.
Learning how to clean a Bissell vacuum properly is partly about knowing what to do — and partly about knowing what not to do. A handful of very common mistakes cause real, lasting damage to the machine, and most of them are completely avoidable once you're aware of them.
This is the single most damaging mistake people make during Bissell maintenance. After rinsing the filter under running water, it looks and feels clean — which makes it tempting to put it straight back into the machine. But even a filter that feels dry on the surface often still holds moisture deeper in the filter material, especially near the center folds or layers.
Pro tip: After rinsing your Bissell filter, let it air dry in a well-ventilated spot for a full 24 hours before reinstalling. Skip the hairdryer — heat can warp the filter material and permanently compromise its ability to trap fine dust particles.
A damp filter restricts airflow even more than a dirty one, meaning your first vacuuming session after cleaning can actually perform worse than before. Trapped moisture also creates conditions where mold and mildew develop inside the vacuum housing, which leads directly back to the odor problems described earlier. Our comprehensive guide on how to clean a vacuum cleaner covers the filter drying step in more detail across multiple brands and filter types.
The brush roll — the rotating bar with bristles at the base of the vacuum head — accumulates hair, thread, and string faster than any other component. When it wraps tightly enough, it stops spinning properly. A jammed brush roll places direct stress on the drive belt and motor, shortening both their working lives considerably. In some models, an overtaxed belt will snap, requiring a replacement part that costs more than a full year of routine filter maintenance.
Most Bissell models allow brush roll removal without any tools at all. Check your model's user manual for the specific release latch location — it's usually a simple tab or coin-slot mechanism on the vacuum head. Once the brush roll is out, cut through accumulated hair with scissors, working in parallel strips along the length of the roll, then pull the debris away cleanly. A toothbrush handles the bristles well. This takes about five minutes and makes a noticeable difference in how the machine performs on carpet, especially in homes with pets or long hair.
Not every component needs the same attention on the same timeline. Some parts require cleaning every week or two; others can go several months between sessions. Getting this timing right keeps the machine running well without turning maintenance into something you dread.
The dirt tank is the most time-sensitive component. Never let it fill past the "max fill" line marked on the tank — running the vacuum beyond that point forces the motor to work significantly harder and accelerates filter clogging at the same time. For most households, that means emptying it every two to three uses. Heavier use or a home with pets may push that to every single use.
| Bissell Component | Recommended Frequency | Cleaning Method |
|---|---|---|
| Dirt tank / dustbin | Every 2–3 uses | Empty, rinse with warm water, air dry completely |
| Washable filter | Once a month | Rinse under cold water, air dry at least 24 hours |
| Brush roll | Every 2 weeks | Remove, cut tangled hair with scissors, brush bristles clean |
| Hose and wand | Every 1–2 months | Check for blockages at bends; rinse if odor is present |
| Exterior vents and housing | Monthly | Wipe with a dry or slightly damp microfiber cloth |
| Non-washable filter | Every 3–6 months | Tap gently over a bin to dislodge dust; replace when discolored |
The vacuum's exterior housing, attachments, and wand don't need weekly attention. A quick wipe-down once a month keeps everything tidy and prevents dust from building up around the vent openings. The vents are worth prioritizing specifically — caked dust around motor vents causes the machine to run hot during longer vacuuming sessions, which accelerates wear on internal components over time.
If you also use a Dyson and want a quick comparison of emptying and maintenance routines across brands, our walkthrough on how to empty a Dyson vacuum is a useful reference point. The core principles are similar, but the specific release mechanisms and filter types differ in ways that are worth knowing before you dive in.
It's a fair question. Vacuum maintenance takes time, and if you're already stretched thin, adding another recurring task can feel unwelcome. But in most households, the answer is clearly yes — and the reasons go beyond just keeping floors clean.
A clean filter can restore suction meaningfully in machines that have been running partially clogged for weeks. The motor runs cooler when airflow isn't restricted. Most vacuums that fail ahead of schedule do so because of heat stress caused by blocked filters or tangled brush rolls — both of which routine maintenance prevents entirely. A Bissell that's properly maintained year-round typically outperforms a neglected machine of a higher original quality.
There's also an air quality benefit worth considering. When a filter captures fine particles effectively, fewer allergens — dust mites, pollen, pet dander — recirculate into the room during vacuuming. For households with young children or anyone who deals with seasonal allergies, a clean filter makes a measurable difference. Choosing the right vacuum for your specific situation also plays into long-term ease of maintenance. Our guide on how to choose the right vacuum cleaner for your home breaks down the key factors to evaluate before buying, including filter accessibility and brush roll design.
Regular cleaning does require some planning. Washing a filter and waiting 24 hours for it to dry means thinking a day ahead — which isn't always convenient when you want to vacuum right now. Some Bissell models use non-washable filters that need periodic replacement, adding a small but ongoing cost. In homes with heavy foot traffic or multiple pets, the brush roll may need clearing every week rather than every two, which can feel frequent at first.
None of these trade-offs are deal-breakers, but they're worth knowing going in. The alternative — skipping maintenance — leads to a vacuum that noticeably underperforms within a few months and wears out significantly faster than it otherwise would. On balance, 15 minutes every couple of weeks is a reasonable investment to keep a machine that likely cost well over $100 running at its best. Consistent upkeep costs you time; neglect costs you money.
