The Tornado BR 18/11 (model 99685E, TPPL battery) is a 24V walk-behind scrubber with dual counter-rotating cylindrical brushes at 1300 RPM on an 18" path, covering 17,969 sq ft per hour. The cylindrical head scrubs and sweeps together, clearing debris without a separate pass. An 11-gallon solution tank and 12-gallon recovery tank back roughly 3 hours of runtime per charge, brush pressure holds at 50 lbs, and the sealed TPPL (Thin Plate Pure Lead) battery needs no watering or acid handling. It fits mid-size, noise-sensitive floors cleaned during occupied hours.
Daytime cleaning in occupied buildings is the case this TPPL build answers, from hospitals and schools to retail floors that cannot wait for an after-hours window. The 18" cylindrical head clears cafeteria debris without a pre-sweep, and at 66 dB the machine works next to classrooms and patient rooms without drowning out the room. Sealed TPPL cells carry no spill risk near care areas, so facilities skip the acid-handling rules that flooded batteries bring.
Two counter-rotating cylindrical brushes turn at 1300 RPM under 50 lbs of pressure, agitating grout lines and textured floor while sweeping loose debris into the path. A 31" parabolic squeegee recovers solution behind them on a 0.6 HP vacuum motor.
An 11-gallon solution tank and 12-gallon recovery tank support about 3 hours per charge on most floors. The 24V TPPL battery is sealed and spill-proof at any orientation, holds a steady voltage through the discharge, and needs no watering or equalization between shifts.
