Demo Nacecare TBG 1620/100 Scrubber
Our Take (from the SES Sales Team)
“The TGB 1620 is a 20 in walk-behind for people who want a bigger tank without a bigger machine. It carries 16 gal of solution with a matching 16 gal recovery tank, which is a lot of capacity for a scrubber that is only 22 in wide, so the operator spends more time cleaning and less time walking to the dump sink. NaceCare rates it at 22,000 sq ft per hour. It runs on two 100 Ah gel batteries that are sealed and maintenance free, for 3 to 3.5 hours of runtime, and a low-voltage shutoff helps protect them from being run down too far. The charger is on board, so it plugs in anywhere. Day-to-day care is simple: the tear-away squeegee uses quick-release blades that change without tools, and a quick-fill hose lets you fill from a tap instead of hauling buckets. Since this is a demo, ask us about the hour meter and condition.”
A large-capacity 20 in pad assist scrubber in a compact body
The NaceCare TGB 1620 is a battery walk-behind automatic floor scrubber from the Twintec line. NaceCare describes it as a large-capacity 20 in scrubber built for the most demanding user. A 20 in pad or brush cleans a 20 in path, the 16 gal solution and recovery tanks keep it working between fills, and NaceCare rates it at 22,000 sq ft per hour.
This is the pad assist version (the TGB 1620T is the traction drive version). It runs on two maintenance-free 100 Ah gel batteries with an onboard charger, and the body is just 22 in wide.
Condition: Demo. Light use, priced below new. Ask our team about this unit’s hours and condition.
