The Tornado BDSO 27/28 Stand-On Scrubber is a high-productivity stand-on machine built for medium to large commercial floor programs where speed, operator comfort, and cleaning effectiveness all matter. At 55,000 sq ft/hr on a 27-inch cleaning path, it covers open floor areas with the operator riding rather than walking — eliminating the fatigue that limits how much floor a walking operator can productively clean in a shift. 126 lbs of down pressure at 160 RPM from dual 350W brush motors drives maximum soil removal from commercial hard floors. The impressive water recovery system leaves floors dry and safe immediately behind the machine. One-handed steering via the easy-turn wheel knob. A unique double scrub button allows the operator to perform a second scrub pass without dismounting — ideal for heavily soiled areas or periodic deep-cleaning passes within a routine shift. 26.4-gallon solution tank and 28-gallon recovery tank support extended runs. 66 dB(A) for cleaning during occupied hours. Two soft brushes and on-board charger included.

Key Features of the Tornado BDSO 27/28
55,000 sq ft/hr — Stand-On Productivity
At 55,000 sq ft/hr, the BDSO 27/28 covers 2.5 times more floor per hour than the BDSO 20/21 and nearly three times the output of a 20-inch walk-behind. This is purpose-built for facilities with large continuous floor areas — big-box retail, wide-aisle warehouse floors, large cafeterias, convention center floor, airport concourse tile, large school gymnasiums — where the productivity gap between a 20-inch walk-behind and a 27-inch stand-on translates directly into fewer hours per shift to clean the same area. For in-house cleaning programs where floor area cleaned per labor hour is the core efficiency metric, the BDSO 27/28’s 55,000 sq ft/hr rate makes a meaningful operational difference.
The BDSO 27/28 applies 126 lbs of down force from its dual brush system to the floor surface — significantly more than the BDSO 20/21’s 48.5 lbs. Two 350W brush motors drive the 27-inch scrub path at 160 RPM. Higher down pressure combined with dual-motor power translates to more effective soil removal from heavily trafficked commercial floors — the brush pads press into the floor texture with 126 lbs of force, dislodging embedded soil that lighter-pressure machines leave behind. The 27-inch path at 160 RPM with 126 lbs of contact force makes the BDSO 27/28 appropriate for floors with significant daily traffic loading and accumulated soil.
Double Scrub Button — Second Pass Without Dismounting
The BDSO 27/28 features a double scrub button — a control that activates a second scrub pass without the operator exiting the platform and repositioning the machine manually. On problem areas — entrance zones, high-traffic intersections, loading dock approaches, food service floor sections — the operator can trigger a second scrub pass in sequence without breaking the cleaning pattern. This is a productivity feature specific to the BDSO 27/28 not available on the BDSO 20/21 or the walk-behind scrubbers.
Impressive Water Recovery — Floors Dry and Safe
The BDSO 27/28’s water recovery system is designed to leave floors dry immediately behind the machine, eliminating the wet trailing that slower-recovery scrubbers leave. A 28-gallon recovery tank — oversized relative to the 26.4-gallon solution tank — ensures the machine never stops due to a full recovery tank before the solution runs out. Dry floors immediately behind a scrubber reduce slip-and-fall exposure and allow the cleaned area to be re-opened to traffic faster, an important operational consideration in facilities that clean during occupancy.
Easy-Turn Steering Knob — One-Handed Operation
The easy-turn steering wheel knob enables full machine control with one hand — the operator maneuvers around obstacles, through aisle intersections, and into position along walls without two-handed grip or significant force. This is the same steering design as the BDSO 20/21, appropriate for stand-on operation in congested commercial facilities where frequent directional changes are required.
66 dB(A) — LEED-Qualifying Quiet Operation
At 66 dB(A), the BDSO 27/28 operates at an LEED-qualifying noise level — below the 70 dB threshold used in LEED cleaning equipment criteria. This enables scrubbing during occupied hours in retail, healthcare, education, and office environments where noise levels are a constraint. For large facilities where the BDSO 27/28’s productivity is needed but cleaning windows are limited by occupancy, 66 dB any-time operation expands when the machine can run.
26.4-Gallon Solution / 28-Gallon Recovery — Extended Run Time
The BDSO 27/28’s 26.4-gallon solution tank and 28-gallon recovery tank are sized for the machine’s high productivity rate — the tanks support long uninterrupted cleaning runs appropriate for large open floor areas at 55,000 sq ft/hr. The recovery tank’s larger capacity than the solution tank ensures recovery never limits run length before the solution is consumed.
Two Soft Brushes and On-Board Charger Included
The machine ships with two soft scrub brushes and an on-board charger — no separate charging station required. The included soft brushes are appropriate for standard commercial floor maintenance; pad drivers are available as an alternative contact surface for facilities using floor pads.

The BDSO 20/21 is the right choice when the floor program is medium-scale and doorway-friendly compactness with one-handed steering is the priority. The BDSO 27/28 is the step up for large facility programs where 55,000 sq ft/hr, 126 lbs of down pressure, and the double scrub capability justify the larger investment.

The double scrub button triggers a second scrub pass without the operator exiting the stand-on platform. On heavily soiled areas — entrance zones, high-traffic floor intersections, food service areas — the operator activates the double scrub function and the machine performs a second cleaning pass in sequence. This eliminates the need to stop, dismount, and manually reposition for problem areas, keeping the cleaning program moving efficiently.
How does the BDSO 27/28 compare to the BDSO 20/21?
The BDSO 27/28 covers 55,000 vs 22,000 sq ft/hr — more than twice the productivity — on a 27-inch vs 20-inch path with 126 vs 48.5 lbs of down pressure. It also includes the double scrub button, dual brush motors, and a 26.4-gallon solution tank vs 14.5 gallons. The BDSO 20/21 is more compact at 377 vs 470 lbs and includes a faucet fill hose the 27/28 does not. Choose the 20/21 for medium-scale programs with tight spaces; choose the 27/28 for large open floor programs where productivity is the priority.
