When your need is for a bigger, but still portable commercial wet or dry cleaner, the 570 series sets entirely its own standard. First you have the full Structofoam construction, in fact a Numatic first, unmatched worldwide. Structofoam is a material formulation embodying all the strength needed for bigger machines, yet without weight penalty. It is really rugged. It doesn’t dent, scratch or deteriorate & yet it is light in weight & resists all standard cleaning chemicals. The power & performance are to the full Twin Flo’ standard with a choice of one or two-motored specifications & both incorporate the Nucable plugged, replaceable cable system as standard. The accessories provided are equally professional being 38mm (1 1/2”) as standard & allowing for full wet or dry operation. The tube sets are stainless steel & a pair of Multiflo’ 400mm (16”) floor nozzles are included both again manufactured in Structofoam
