Industrial and commercial areas are constantly increasing in size, and applications are becoming ever more specific. Hako’s new Scrubmaster B400 R Series meets the requirements associated with large-scale tasks. Both the new scrubber-driers and vacuum sweeper & scrubber-drier combi machines ensure long, uninterrupted working, with high area performances of up to 14,000 m²/h thanks to large 400-litre solution and recovery tanks, and a maximised battery capacity provided by the optional battery changing system.  The new product series offers a particularly wide range of application options through three different machine variants, 3-disc-brush units available in working widths of 123 cm and 155 cm, sophisticated extras as a standard, as well as numerous individually selectable options and tools for more efficiency, flexibility and occupational safety.
