New Powerboss Nautilus HD GAS
Our Take (from the SES Sales Team)
“The Nautilus HD is a sweeper-scrubber for floors that are dirty in every sense: plants, warehouses with dock traffic, stadium concourses and outdoor areas. It scrubs a 45 in path with two 12 in cylindrical brushes and up to 400 lb of down pressure, and with the optional side brushes the path grows to 60 in scrubbing or 62 in sweeping. The brushes throw debris into a 3.89 cu ft stainless steel hopper, and the HD is the high-dump version, so the hopper lifts hydraulically and dumps hands-free at variable heights up to 60 in, right into a dumpster. The 90 gal solution and recovery tanks keep it working through big areas. This unit runs on a 1.5 L Kubota gasoline engine, a good fit for outdoor work and sites where charging a big battery machine is not practical. It is a big machine at 95 in long and 3,250 lb empty, so measure aisles and check floor loading before you commit.”
