The HydraPort series of portable extractors are the culmination of a major engineering and design initiative by U.S. Products that started with direct input from cleaning technicians who use portable extraction machines every day. The HydraPort series represents a dramatic step forward in implementing unique safety and productivity-enhancing features that consider even the minutest details. For example, the solution tank filling site is moved to a location where the inevitable spill does not come in contact with any electrical components or switches. In addition, the whisper quiet, sealed vacuum system muffles sound for quieter operation in noise-sensitive environments. Essentially, no detail was overlooked.
