Product description
The MA50 15B is the machine you buy when a mop and bucket is no longer defensible but a full-size autoscrubber will not fit the room. Its 15-inch disc deck and 3.5-gallon tank set clear roughly 8000 square feet an hour in classrooms, restrooms, back-of-house kitchens, offices and retail aisles, scrubbing and drying in a single pass so the floor is walkable immediately. The low-profile body slides under fixtures and around toilet partitions, and the pad-assist drive lets the brush pull the machine forward instead of the operator pushing it. Two sealed 12V AGM batteries and an onboard charger give about two hours of run time with no cord to manage and no wall outlet to hunt for. A fold-down handle and lift-off recovery tank make storage in a janitor closet and end-of-shift dumping a one-person job.
- 15-inch (38 cm) disc scrub path with a 20-inch (51 cm) rounded squeegee, so recovery is wider than the scrub path and solution is picked up in one pass.
- Pad-assist drive: the 0.33 hp (250 W) brush motor pulls the machine forward, cutting operator push effort on long runs.
- 3.5-gallon (13.5 L) solution and 3.5-gallon (13.5 L) recovery tanks, sized for a full room-by-room route without a refill stop.
- Two 12V 33 Ah sealed AGM batteries with an onboard charger and auxiliary charging cable for charging away from the home closet.
- Rated up to 8000 sq ft/hr cleaning productivity and roughly two hours of battery run time per charge.
- 44.5 lb (20 kg) of pad pressure at 150 rpm — enough down-pressure for daily soil removal on VCT, sealed concrete and tile.
- 40 in (100 cm) water lift from the 0.33 hp vacuum motor, leaving floors dry enough to reopen immediately.
- 70 dB(A) sound level, quiet enough for daytime cleaning in occupied offices, clinics and classrooms.
- Low-profile chassis at 30 x 20 x 21.7 in reaches under desks, sinks and fixtures that block a full-size scrubber.
- 124 lb (56 kg) machine weight with a fold-down handle and lift-off recovery tank for closet storage and single-operator dumping.
Receiving — do not sign clean
- Count the pieces against the bill of lading before the driver leaves. A machine, its batteries and its accessories can ship as separate items.
- Walk the pallet. Check the shrink-wrap, the crate corners and the machine itself — forks go through crates more often than anyone admits.
- Photograph any damage before you sign. Once the driver has your signature the photographs are worth much less.
- Write the damage on the delivery receipt. A clean signature on a damaged pallet is what makes a freight claim hard. Then call 1-888-287-3732 the same day.
