NaceCare TBL 1620/100T K-916865-C2B Battery Scrubber – 20", 2×NX1K, 3.5 Hr
NaceCare TBL 1620/100T K-916865-C2B – 20-Inch Traction Drive Battery Scrubber, 3.5-Hour Runtime
The NaceCare TBL 1620/100T (part number K-916865-C2B) is a traction-drive walk-behind scrubber powered by two NX1K lithium phosphate batteries delivering 3.5 hours of runtime. With a 20-inch cleaning path, 90 lbs of brush pressure at 150 RPM, and 16-gallon solution and recovery tanks, this machine covers 22,000 square feet per hour — appropriate for commercial facilities, healthcare environments, schools, and hospitality venues that need sustained cordless cleaning across long shifts.
TBL 1620/100T K-916865-C2B Traction Drive and NX1K Battery Performance
- 20" cleaning path / 22,000 sq ft/hr: traction drive propels the machine at consistent speed, removing operator effort needed to push a fully loaded 16-gallon scrubber across large floors.
- 2×NX1K lithium phosphate batteries, 3.5-hr runtime: NX1K cells support over 4,000 charge cycles — roughly 10× longer than sealed lead-acid alternatives — and recharge in 5 hours without memory effect.
- 90 lb brush pressure at 150 RPM: sustained downforce for daily scrubbing on concrete, tile, terrazzo, and coated warehouse floors without operator fatigue from hand-pressing the machine.
- 16-gal solution / 16-gal recovery tanks: matched capacity prevents solution from running out before recovery fills, allowing a full tank run without stopping.
- 250W traction motor: self-propels on inclines and uneven surfaces where pad-assist models require operator push force to maintain forward movement.
- No electronics, no actuator motors: toggle switch controls simplify the operator interface and reduce failure points compared to electronically controlled competitors.
Facilities and Shifts Where the TBL 1620/100T Outperforms Corded Alternatives
The 3.5-hour runtime covers a full cleaning shift without recharging or switching machines. In healthcare facilities where cord tripping hazards are unacceptable in patient-access corridors, the cordless traction-drive operation eliminates both hazards simultaneously. In retail and hospitality settings, the machine cleans floor areas during low-traffic windows without managing extension cords across customer paths. The NX1K battery system charges to full in 5 hours — machines charged during a day shift are ready for a full evening cleaning run without opportunity charging.
NX1K Battery System Maintenance and Serviceability
NX1K lithium phosphate batteries require no water topping, no equalization charges, and no corrosion inspection — maintenance steps that lead-acid battery systems require weekly. Batteries can be charged at any state without reducing capacity, unlike lead-acid systems where partial charging degrades cell life. The 5-year battery warranty reflects NaceCare's confidence in NX1K cycle durability. The Nu-Assist app provides on-demand training and maintenance guidance accessible from a smartphone without waiting for a service technician.
