Tested: How to Clean a Bissell CrossWave Brush Fast

Why Your Bissell CrossWave Brush Gets So Gross

I've owned my Bissell CrossWave Pet Pro for over three years. It's an absolute lifesaver for hard floors and low-pile area rugs. But I'll be honest, the brush roll gets completely disgusting if you ignore it. When your kids track in wet spring mud or your dog shakes off after a walk, that multi-surface brush absorbs everything. Left alone, it turns into a smelly, bacteria-filled tube of grime.

I've tested dozens of cleaning routines to figure out what actually works. The secret is consistency. You can't just run the self-cleaning cycle and walk away. The machine only does half the job. If you want to know how to clean a Bissell crosswave brush properly, you need a solid manual routine. This guide breaks down exactly what I do to keep my machine smelling fresh and mopping perfectly.

The 5-Minute Routine Clean (After Every Use)

You must do this after every single mopping session. I know it's tempting to just put it back in the closet after hosting a dinner party. Don't. Taking five minutes now saves you hours of scrubbing later.

1. Empty the dirty water tank immediately into the toilet or outside.
2. Rinse the tank with warm tap water (around 80°F) to remove silt.
3. Fill the clean water tank to the max line with warm water.
4. Add exactly one capful of Bissell Multi-Surface Formula.
5. Place the machine on the plastic rinse tray.
6. Hold the power button for 3 seconds to start the self-cleaning cycle.

This cycle runs for about 3 minutes. It flushes the internal tubes and spins the brush at high speed. Once it stops, remove the brush roll. I always pull it out by the plastic tab on the left side. Rinse it under the sink for 30 seconds. Squeeze out the excess water with your hands. Let it air dry on the tray.

The Deep Clean (For Stubborn Smells and Pet Hair)

Sometimes the self-clean just isn't enough. If you have a Golden Retriever shedding everywhere, hair wraps tightly around the brush ends. This isn't the easiest thing to fix, but it's completely necessary. I do this deep clean every two weeks to keep the machine running smoothly.

First, remove the brush roll. Grab a pair of scissors or a seam ripper. I use a $5 seam ripper from the craft store because it gets right into the grooves. Snip the hair wrapped around the plastic ends. Pull it off in one big clump.

Next, fill a basin with 1 gallon of hot water (about 120°F). Add 1/2 cup of white vinegar and 2 tablespoons of baking soda. Submerge the brush roll completely. Let it soak for exactly 15 minutes. The vinegar breaks down hard water stains and kills odor-causing bacteria. The baking soda lifts embedded dirt from deep inside the bristles.

After 15 minutes, scrub the bristles with an old toothbrush. Rinse it thoroughly under cold running water. Squeeze it until the water runs completely clear. Stand it upright to dry for at least 12 hours. Never put a wet brush back into the machine. It will mildew instantly and ruin your floors.

Cleaning the Brush Window and Filter

A clean brush won't matter if the housing is filthy. I've seen so many people complain about streaky floors. The culprit is usually the brush window, not the brush itself.

Pop off the clear plastic cover over the brush roll. Wash it in the sink with dish soap. Use a microfiber cloth to wipe the inside of the brush chamber. You'll find a surprising amount of sticky residue in there. I usually have to scrape the corners with my fingernail to get the dried pet food out.

Then, check the filter. It sits right above the dirty water tank. Pull it out. Tap it against the inside of your trash can to knock loose dry dust. Rinse it under cold water. Do not use soap on the filter. It ruins the membrane and blocks airflow. Let the filter dry for 24 hours. I always buy a two-pack of replacement filters (usually around $15-$20) so I always have a dry one ready to go.

What Cleaning Solutions to Avoid

I've made the mistake of using the wrong soap in the past. It ruined a brush roll and clogged the spray jets. Never use bleach directly in the clean water tank. It eats the rubber gaskets and voids your warranty. Avoid Pine-Sol, Fabuloso, or any thick, oily cleaners. They leave a sticky film that actually attracts more dirt to your floors.

Stick to Bissell's official formulas or a very dilute mix of white vinegar and water. And only use the vinegar mix for the manual soak, never in the tank. I once tried a generic floor cleaner from a big box store. It foamed up so much the machine lost suction and leaked everywhere. Stick to low-sudsing options designed specifically for wet vacuums.

Cleaning the Dirty Water Tank and Filter Screen

The dirty water tank is ground zero for gross smells. I empty it right after mopping. But once a week, I take it apart completely to prevent mold buildup.

Pull the main filter out. Remove the plastic filter screen located just below the filter. It pops out with a gentle pry from your thumb. You'll find a layer of slimy pet hair and fine dust here. Wash the screen with warm soapy water. Use a bottle brush to scrub the inside of the dirty tank. The bottom corners trap fine silt that just rinsing won't remove. Let every single piece air dry completely before reassembling. If you put it away damp, you'll get a sour mildew smell that is nearly impossible to remove.

Bissell CrossWave Models: Brush Differences

Not all CrossWave brushes are identical. I've tested a few different models in my home and my parents' house. Here is a quick breakdown of what you might be working with. Make sure you buy the right replacement.

Model	Brush Type	Best For	Replacement Cost
Standard CrossWave	Multi-Surface (Green)	Hard floors & low pile rugs	$20-$25
CrossWave Pet Pro	Pet Multi-Surface (Purple)	Pet hair & heavy messes	$25-$30
Cordless Max	Multi-Surface (Blue)	Quick daily cleans	$25-$30
Wood Floor Model	Soft Microfiber (Brown)	Sealed hardwood only	$20-$25

Troubleshooting Common Brush Issues

Even with perfect cleaning habits, things go wrong. Here is how I fix the most common problems I've encountered over the years.

Brush won't spin

Check the ends of the roller. If hair jams the bearings, the motor protects itself and stops. Clear the debris with your seam ripper. If it still won't spin, the internal belt might be broken. Replacing the belt takes about 10 minutes and costs around $8 online.

Leaving streaks on the floor

Your brush is either too dirty or too wet. Make sure you wring it out properly after washing it in the sink. Also, check your clean water tank. If you use too much soap, it leaves a filmy residue that dries into streaks. Stick to the fill lines.

Smells like wet dog

The brush didn't dry completely before you stored it. I keep a small $15 desk fan pointing at the drying tray. It cuts drying time in half. If the smell persists, soak the brush in a 10% bleach solution for 5 minutes. Rinse it extremely well afterward.

Pro Tips for Extending Brush Life

I always keep a spare brush roll in the closet. When I finish mopping, I swap the wet brush for the dry spare immediately. This ensures I always have a dry brush ready for unexpected spills. It also gives the wet brush a full 24 hours to dry out completely.

Pre-sweep the floor when you can. I know it slightly defeats the purpose of a vacuum-mop combo. But picking up large pieces of kibble or big clumps of mud saves the brush from unnecessary wear and tear. It keeps the bristles from matting down prematurely.

Store the machine in a climate-controlled area. Don't leave it in a damp basement or a freezing garage. Extreme temperatures and high humidity will degrade the brush fibers and promote mold growth inside the machine.

Frequently Asked Questions

How often should I replace my Bissell CrossWave brush roll?
I recommend replacing the brush roll every 3 to 6 months, depending on how often you mop. If you use it daily on heavy pet hair, lean closer to the 3-month mark. You'll know it's time when the bristles look frayed or permanently flattened.

Can I wash the Bissell CrossWave brush in the washing machine?
No, you should never put the brush roll in a washing machine or dishwasher. The high heat and aggressive agitation will melt the plastic core and ruin the bristles. Hand washing in the sink is the only safe method.

Why does my Bissell CrossWave leave dirty streaks on the floor?
Streaks usually happen when the brush roll is saturated with dirty water or you're using too much cleaning solution. Make sure you empty and rinse the dirty water tank immediately after use. Always measure your cleaning formula carefully instead of just eyeballing it.

Is it safe to use vinegar to clean the CrossWave brush?
Yes, white vinegar is excellent for soaking the brush roll to remove hard water buildup and odors. However, never put vinegar directly into the machine's clean water tank. The acidity can degrade the internal rubber seals and plastic tubes over time.

How do I get pet hair out of the ends of the brush roll?
I use a cheap seam ripper or a pair of small scissors to carefully cut the wrapped hair. Pull the brush roll out of the machine first to give yourself better access. Snip the hair close to the plastic bearing, then pull the clump off by hand.
