EX20™ portable extractors are the culmination of a major engineering and design initiative of Clarke that emanated from direct field input of cleaning technicians who used high performance portable extraction machines every day. The EX20 represents a dramatic step forward in implementing unique, productivity enhancing features that considered even the minutest detail. These features go a step beyond traditional componentry that is common to most extractors – pumps and vacuum motors – and take into account the most common annoyances expressed by cleaning technicians. For example, moving the solution tank filling site to a location where the inevitable spill does not come in contact with any electrical components or switches. No detail was overlooked.
