Description
The NaceCare TBL 1620/100 (K-916859-C2B) is the two-battery, brush-drive version of the 20-inch TBL 1620, giving up to 3 hours 50 minutes of cleaning per charge. Two NX1K lithium phosphate batteries, 16-gallon tanks and up to 22,000 sq ft per hour make it a fit for long cleaning runs on large commercial floors.
Highlights
- Two NX1K lithium phosphate batteries: up to 3 hours 50 minutes of runtime from one full charge.
- 5-hour full recharge: charge at any point without harming the batteries, per NaceCare.
- 16-gallon solution and recovery tanks: fewer refill and dump stops on large areas.
- 90 lbs brush pressure at 150 RPM: firm downforce for daily scrubbing of hard floors.
- Brush drive: the rotating brush helps move the machine forward to reduce push effort.
- Maintenance-free batteries rated for over 4,000 cycles: no watering or equalizing.
Details
The TBL 1620/100 suits commercial, education, healthcare, hospitality and retail sites that need close to four hours of cordless scrubbing in one session. It shares the 20-inch path and 16-gallon tanks of the single-battery TBL 1620/50 (916859) but nearly doubles the runtime; the TBL 1620/100T adds a traction drive.
