The Clarke EX20-100C Portable Extractor (Machine Only) (56105288) is the culmination of a major design initiative directed by field input from cleaning technicians who utilitize high performance portable extraction machines daily. The EX20 was designed beyond the traditional componentry such as pumps and vacuum motors with attention to detail on the most common issues expressed in the cleaning industry. A recessed electronic switch for protection against water exposure, front panel roller wheels for easier unloading, compatible 12" stainless steel wand (not included), are some of the features that make this extractor a great choice for any cleaning professional.
