The Nautilus HD delivers the same exceptional performance and dependability as the renowned Nautilus, but it comes with an innovative hands-free high-dump feature designed for operators. Its sturdy all-steel frame, specifically tailored for industrial/commercial use, and lifting arms with a 400 lbs. Similar to its counterpart, the Nautilus HD utilizes a single set of cylindrical brushes, efficiently handling both sweeping and scrubbing tasks in a single pass. With a tank capacity of 95 gallons and an all-stainless steel scrubbing deck, it maintains the durability and reliability expected from the Nautilus family. Notably, the Nautilus HD offers an optional onboard self-generating hot water system, known as TGT (Thermal Green Technology), which taps into the heat generated by the internal engine. This system elevates cleaning water temperatures by up to +70 degrees above the ambient temperature, significantly enhancing cleaning results in a wide range of applications. Additionally, both operators and mechanics prefer the Nautilus HD for its ease of maintenance, convenient access to the hopper, tool-free brush changes, one-touch operation, and its all-hydraulic design.
