New Powerboss Nautilus HD LPG
Our Take (from the SES Sales Team)
“The Nautilus HD LPG is a sweeper-scrubber for big, dirty floors: manufacturing plants, distribution centers, stadium concourses and parking structures. Running on propane makes it a practical fit for sites that already keep LPG cylinders on hand for forklifts. It works a 45 in path with two 12 in cylindrical brushes and up to 400 lb of down pressure, picking up debris into the hopper while it scrubs, and optional side brushes widen that to 60 in scrubbing or 62 in sweeping. As the HD (high-dump) model, the 3.89 cu ft stainless steel hopper rises hydraulically and empties at variable heights up to 60 in, so nobody has to shovel it out. The engine is a 1.5 L Kubota WG1605L, rated by PowerBoss at 39.4 hp governed at 2,400 rpm, and the 90 gal solution and recovery tanks keep it scrubbing longer between stops. At 95 in long and 3,250 lb empty, it needs room, so measure aisles and turns before you decide.”
