Tornado Torrent 28 Battery Walk-Behind Sweeper – 10-Gal, 4-Hr Runtime

Tornado Torrent 28 Battery Walk-Behind Sweeper – Tandem Roller System, 10-Gallon Hopper, 4-Hour Runtime

The Tornado Torrent 28 (model TW050-W28-U) is a 24V AGM battery walk-behind sweeper featuring the proprietary Tandem Roller System (TRS) with dual counter-rotating brushes, a 10-gallon hopper, and a 4-hour runtime on a 12V/75Ah AGM battery pack. It covers 30,139 sq. ft. per hour with a sweeping path that extends from 23.6" retracted to 28" with the foldout side broom deployed, and operates at 54 dB(A) — quiet enough for schools, hospitals, and occupied retail spaces.

Torrent 28 Specs: Hopper, Battery, Brushes, and Filtration

• Sweeping path: 28" extended / 23.6" retracted — the foldout side broom adds edge coverage without requiring separate passes along baseboards
• Hopper capacity: 10 gallons — large enough for extended runs in warehouses and distribution centers without frequent dumps
• Battery: 12V / 75Ah (C20) AGM, 24V system — 4-hour runtime, 6-hour recharge via onboard charger
• Productivity: 30,139 sq. ft./hr — covers roughly 0.7 acres per hour in open floor areas
• Noise: 54 dB(A) — among the quietest battery sweepers in this class, suitable for occupied environments
• Main brush: 16" cylindrical with TRS dual counter-rotating configuration for debris capture from fine dust to coarse sand
• Side brushes: 2 rotary — foldout, self-retracting to protect surfaces when not needed
• Filtration: single-stage flat-pleat filter with manual shaker and continuous suction dust control; suction off switch for wet debris
• Weight: 128 lbs without batteries / 181 lbs with batteries; dimensions 59" × 27.5" × 43"

Where the Torrent 28 Is Used in Commercial and Industrial Facilities

The Torrent 28 is sized for facilities that are too large for manual sweeping but where a ride-on sweeper's footprint or cost is not justified. Distribution centers and light manufacturing plants use its 10-gallon hopper and 30,000+ sq. ft. per hour coverage to sweep production floors between shifts without pulling workers off line. Retail big-box stores and supermarkets run it during off-hours at 54 dB(A), low enough that background music covers the operating noise. Schools and university buildings schedule it for early-morning corridor sweeping before students arrive — the LED headlight illuminates debris in dimly lit pre-dawn hallways. Hospital service corridors and parking structures benefit from the suction off switch, which disables the vacuum system for wet or sticky debris that would clog the filter if vacuumed. The foldout side broom handles columns, shelving bases, and wall edges without requiring separate manual sweeping of those zones.

Side Brush Operation, Debris Types, Hopper Emptying, and Battery Chemistry

The Torrent 28's two rotary side brushes fold out to extend the sweeping path to 28" and retract automatically when the machine reverses or the operator activates the retract control, preventing brush contact with obstacles during maneuvering. The Tandem Roller System captures debris ranging from fine particulate dust and sand up to coarse material including gravel, staples, and paper debris common in distribution and retail environments. The 10-gallon hopper empties by releasing the front hopper latch, tilting the hopper forward and away from the machine body, and dumping contents directly into a waste container — no tools required, and the process takes under 60 seconds. The 12V / 75Ah (C20) AGM battery chemistry does not require watering, is sealed against spills, and tolerates partial-state-of-charge operation better than flooded lead-acid, making it practical in facilities that cannot guarantee a full 6-hour charge window every cycle. The onboard charger is integrated — plug in to a standard outlet and the machine charges in place without removing the batteries.
