Tornado OB 20/14 Orbital Floor Scrubber – Walk-Behind, 2200 RPM, 110 Lbs, TS350-W20-U

Tornado OB 20/14 Orbital Floor Scrubber

The Tornado OB 20/14 (models TS350-W20-UC / UG / UE) is a 24V walk-behind orbital scrubber whose rectangular 20"×14" pad reaches baseboards and 90° corners a round disc head leaves untouched. The random-orbital head runs at 2,200 RPM, stripping floor finish with little water and no stripping chemicals, and covers a theoretical 24,219 sq. ft. per hour. With up to 110 lbs of adjustable down pressure, 14-gallon solution and recovery tanks, a 400W traction drive for 10% ramps, and 3–4 hours of runtime, it handles VCT corridors, terrazzo, and polished concrete in schools, healthcare, and retail.

OB 20/14 Orbital Speed, Down Pressure, and Corner Access

Brush speed is what sets an orbital apart from a disc machine: 2,200 RPM against the 160–190 RPM of a typical disc scrubber, paired with a rectangular pad that contacts the full edge of the path.

• 2,200 RPM orbital motion — chemical-free finish removal on VCT, terrazzo, and polished concrete; cuts water and chemical use during daily maintenance
• Rectangular 20"×14" scrub head — reaches corners and edges that round disc scrubbers miss, so a secondary hand-scrub pass isn't needed
• 110 lbs adjustable down pressure — up for stripping, back down for daily scrub and spray buff; one machine covers both workflows
• 400W traction motor — handles ramps to 10% grade with full 14-gallon tanks
• Lifetime warranty on isolators — the vibration-dampening system that protects operator hands is warranted for life
• Under 70 dB(A) — runs during occupied hours in retail, healthcare, and hospitality without disrupting operations

OB 20/14 Applications and Environments

Schools and universities with large VCT corridors are the primary fit. Edge-to-edge corner coverage plus chemical-free stripping removes the two-step strip-and-mop workflow that usually forces floor closures. Hospitals and outpatient clinics use it on polished terrazzo and epoxy without bringing stripping chemicals near patient areas. Retailers with sealed concrete or VCT run it for overnight finish maintenance, switching between spray-buff pads (white) and daily scrub pads (blue) on the same machine. Hotels with large VCT lobbies and long corridors specify it for nightly runs, where 14-gallon tanks and 3–4 hours of runtime cover most mid-size properties on a single charge.
