New NSS Wrangler 3330DB Disk Walk-Behind Scrubber - 330Ah AGM Battery
Our Take (from the SES Sales Team)
“The Wrangler 3330 DB is the biggest walk-behind NSS builds, and it makes sense for open floors where a rider would be more machine than you need: big-box retail, hospital corridors, hotel back-of-house and light industrial space. Two 17 in brushes or pads clean a 33 in path, and NSS rates it at 20,400 sq ft per hour of practical coverage. The 30 gal solution tank and 32 gal recovery tank mean fewer trips to dump and refill on a long route. This unit runs on six 6 V, 330 Ah AGM batteries, rated by NSS for up to 3.7 hours with no battery watering, and the charger is on board. Controls are a few switches and mechanical levers with a twist throttle, so new custodians can be trained in minutes. On the 3330 the brush motors are centered, and the skirt design gives it the offset for edge work. If your aisles are tighter, the Wrangler 2730 DB has the same tanks with a 27 in deck.”

The NSS Wrangler 3330 DB is a battery-powered walk-behind automatic scrubber with a 33 in disk scrub deck.
