The Tornado BD 20/11L (model TS120-S45-U) is a 24V brush-assist walk-behind scrubber that cleans a 20-inch path and covers 17,969 sq. ft. per hour. An 11-gallon solution tank and 12-gallon recovery tank feed a deck that holds 48.5 lbs of brush pressure at 155 RPM, and one charge runs 3 to 4 hours. Under 70 dB, it scrubs stockrooms, clinics, and school corridors daily without drowning out the people working around it.

Who the BD 20/11L Is For
Brush assist suits operators working shorter runs, where pushing the machine never turns into the bottleneck. Retail stockrooms, medical offices, and small school hallways are natural fits, as are sites that would rather spend less up front than pay for a self-propelled traction drive. Stripped of its battery the chassis weighs 157 lbs, light enough for one person to wheel into corners and through doorways. Crews covering large floors across long shifts tire less on the LT traction model, but for compact zones this brush-assist unit cleans the same path for less.
How the Brush Deck, Tanks, and Battery Work
The deck spins a single brush at 155 RPM under 48.5 lbs of pressure, which lifts ground-in soil from VCT, sealed concrete, and tile in one pass. Solution drops from the 11-gallon tank ahead of the brush; behind it, the 31-inch squeegee and 0.6 hp vacuum pull the dirty water into the 12-gallon recovery tank and leave the floor dry enough to walk on.
Power comes from a 24V battery set, either Lead Acid or AGM, charged through the on-board charger. A full charge keeps it scrubbing 3 to 4 hours, enough for most single-shift routes to finish without a battery swap.

Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
