New Nobles SS350 20" Disk Stand-On Scrubber
Our Take (from the SES Sales Team)
“A stand-on scrubber like the Speed Scrub 350 fills the gap between a walk-behind and a full rider, and the 20 in version is the one for tighter buildings. The operator stands on the machine, so they move faster than walking, up to 3.6 mph, and can step off in a second to move a chair or pick something up. At 26.5 in wide and 55 in long, it fits into hospital corridors, grocery aisles, cafeterias and school hallways where a seated rider would be awkward. Nobles rates the 20 in model at 24,588 sq ft per hour of practical conventional scrubbing, with a 14.1 gal solution tank and an 18.4 gal recovery tank. It is also quiet, at 63.7 dBA. This base configuration has the Pro-Membrane control panel with zone settings and supervisor lockouts, Insta-Click magnetic pad attachment, wet 210 Ah batteries and an on-board charger. If you want the longest run time, ask about the 240 Ah battery upgrade. For wider-open floors, the 24 in SS350 adds a second disk and more coverage.”
