Tornado OB Orbital Walk-Behind Scrubber

Tornado OB Orbital Walk-Behind Scrubber — OB 20/14 and OB 28/20

The Tornado OB Orbital Walk-Behind Scrubber is the only walk-behind scrubber in the Tornado lineup built around a rectangular orbital scrub head — a geometry that reaches into corners and along floor edges that round disk heads cannot clean, delivering an even floor finish removal across the full cleaning path including room perimeters. High-RPM orbital action provides chemical-free finish removal and significantly reduces water and chemical consumption during routine daily cleaning. Adjustable down pressure delivers industry-best contact force between the pad and the floor surface. The traction-drive motor provides effortless movement up ramps to a 10% grade. Fingertip controls. On-board charger included. Tornado backs the isolator system with an industry-leading lifetime warranty — the engineered isolators reduce vibration transmitted to the operator’s hands, reducing fatigue over extended cleaning shifts.

Available in OB 20/14 (TS350-W20-U) with a 20×14″ rectangular head at $10,000.00 and OB 28/20 (TS550-W28-U) with a 28×14″ rectangular head at $12,200.00. Both carry identical warranty coverage: 4-year parts / 10-year roto / Lifetime Isolator / 2-year labor.

OB 20/14 vs OB 28/20 — Choosing Your Width

The OB 20/14 at 262 lbs and 21.5″ body width navigates tighter corridors and mid-size commercial spaces efficiently at 24,000 sq ft/hr. The OB 28/20 at 3,530 RPM is the highest orbital brush speed in the Tornado lineup — Tornado calls it industry-leading — covering 33,000 sq ft/hr with 132 lbs of down pressure and a 28-inch cleaning path suited to large open floor areas. The 28/20 requires four batteries vs two for the 20/14. Call us at 763-535-0770 to discuss which fits your application.

Key Features of the Tornado OB Orbital Walk-Behind Scrubber

Rectangular Orbital Scrub Head — Reaches Corners and Edges

Standard disk scrubbers use a circular pad driver that leaves uncleaned crescents in every corner and along every baseboard — the round head cannot physically reach into a 90° corner. The OB’s rectangular orbital scrub head eliminates that gap. The flat leading and trailing edges of the rectangular head press pad contact into corners and along wall edges in the same pass as open floor cleaning — delivering an even finish removal across the full floor area including perimeters that disk scrubbers consistently miss. For facilities where floor appearance at walls and corners matters — retail showrooms, healthcare lobbies, school corridors — the rectangular head geometry is a meaningful operational difference from disk scrubbing.

Industry-Best Down Pressure — Chemical-Free Finish Removal

The OB series applies up to 110 lbs (OB 20/14) or 132 lbs (OB 28/20) of adjustable down pressure — among the highest in the walk-behind scrubber market at these cleaning widths. At high down pressure combined with orbital RPM, the OB generates enough mechanical energy to remove floor finish chemically-free — stripping wax and finish buildup without stripping chemicals — reducing chemical cost, eliminating the disposal and safety handling requirements of stripping chemistry, and cutting the time investment of a full strip-and-recoat cycle. For facilities on regular finish maintenance programs, the OB’s chemical-free removal capability can eliminate dedicated stripping passes and reduce the chemistry budget for floor care.

Industry-Leading 3,530 RPM Orbital Speed — OB 28/20

The OB 28/20’s dual 350W brush motors drive the orbital head at 3,530 RPM — the highest orbital brush speed in the Tornado walk-behind lineup, and what Tornado describes as industry-leading for a machine at this cleaning width. Higher RPM at high down pressure increases the mechanical energy applied per square foot of floor surface — more effective finish removal, more thorough daily cleaning penetration, and greater productivity per operator hour. The OB 20/14 operates at 2,200 RPM with a 750W single motor; the OB 28/20’s dual-motor 3,530 RPM configuration represents a step up in cleaning intensity appropriate for facilities with heavier floor soiling or higher finish maintenance demands.

Lifetime Isolator Warranty — Reduced Operator Vibration Fatigue

High down pressure orbital scrubbing generates significant vibration — at 110–132 lbs of force against the floor and RPM speeds of 2,200–3,530, the machine transmits considerable mechanical energy through the handle to the operator’s hands and arms during extended cleaning shifts. Tornado engineers the OB’s isolator system specifically to reduce this vibration transmission, protecting operator comfort over multi-hour cleaning programs. The isolators carry a lifetime warranty — the only component on the OB (or any Tornado walk-behind) with lifetime coverage. This warranty reflects Tornado’s confidence in the isolator design and its importance to the machine’s long-term usability.

Traction-Drive Motor — Ramps Up to 10% Grade

Both OB models use a dedicated 400W traction-drive motor that propels the machine independently of the scrub system. The drive motor handles ramps up to a 10% grade — loading docks, ramp connections between building levels, sloped warehouse areas, and varied-grade commercial facilities — without the operator straining to push the machine uphill. At high down pressure, a brush-assist design would struggle significantly on grades; the dedicated traction motor eliminates that limitation entirely.

Significantly Reduced Water and Chemical Usage

Orbital action at high RPM and down pressure achieves cleaning and finish maintenance results with significantly less solution per square foot than conventional disk scrubbing at equivalent soil levels. The OB’s mechanical cleaning efficiency means less chemistry is needed to achieve the same result — reducing solution cost per shift, reducing floor dry time after cleaning, and reducing chemical residue left on the floor surface. For facilities running daily or multiple-daily cleaning programs, this reduction in chemical usage compounds into meaningful operational savings over a machine’s service life.

Fingertip Controls — Minimal Training Required

All OB functions are accessible from the handle without repositioning the operator’s hands — solution flow, drive speed, and scrub engagement are fingertip operations. Tornado designs the OB’s control layout for fast operator onboarding, appropriate for facilities where cleaning staff operates the machine with variable training time available.

Frequently Asked Questions — Tornado OB Orbital Walk-Behind Scrubber

What makes orbital scrubbing different from disk scrubbing?

A disk scrubber uses a round pad rotating on a vertical axis — effective on smooth flat floors, but leaves uncleaned areas in corners and along edges, and removes finish primarily through chemical action. An orbital scrubber moves the pad in a rapid elliptical pattern at high RPM and high down pressure — the rectangular head reaches into corners and along walls, and the mechanical energy at 2,200–3,530 RPM generates enough scrubbing force for chemical-free finish removal and significantly reduced chemistry use during routine daily cleaning.

Can the OB really remove floor finish without stripping chemicals?

Yes — this is one of the OB’s primary selling points as stated by Tornado. The combination of up to 132 lbs of down pressure and 3,530 RPM orbital action generates sufficient mechanical energy to remove floor finish buildup without stripping chemistry. This eliminates the cost, handling requirements, and floor dry time associated with liquid strippers on regular maintenance floors. For periodic full strip-and-recoats, heavy buildup may still require chemical stripping; the OB’s value is in reducing or eliminating chemical stripping from the routine maintenance cycle.

How does the lifetime isolator warranty work?

Tornado warrants the OB’s isolator components — the vibration-dampening system between the scrub head and the operator handle — for the lifetime of the machine. If the isolators fail under normal use, Tornado covers the parts. This is the longest warranty of any component on the OB and reflects the isolator system’s role as a core engineering differentiator of the machine. For operations where operators run the machine for extended daily shifts, the isolator system’s reduction of vibration fatigue is a meaningful ergonomic benefit.

What is the difference between the OB 20/14 and OB 28/20?

The OB 28/20 has a wider 28″ cleaning path vs 20″ on the 20/14, covers 33,000 vs 24,000 sq ft/hr, runs at 3,530 RPM vs 2,200 RPM, applies up to 132 vs 110 lbs of down pressure, and requires four batteries vs two. The OB 20/14 is lighter (262 vs 348 lbs) and narrower for tighter spaces. Both share the same rectangular orbital head geometry, traction drive, lifetime isolator warranty, and warranty terms. The 28/20 is appropriate for larger open floor programs; the 20/14 for mid-size facilities or spaces with tighter navigation requirements.

Why do the OB 20/14 and OB 28/20 use different squeegee parts?

The machines use different squeegee assemblies sized to their respective squeegee widths (30″ vs 39″) and designed around their different body configurations. Front and rear squeegees are not interchangeable between models — always order by catalog number. See the parts tables above or call us at 763-535-0770 to confirm.
