The Evolution carpet wand is light, durable, and more efficient than any other wand on the market today! Through scientific testing, the Evolution was designed to smooth airflow and boost water recovery performance. The rotationally molded head and aircraft aluminum tube combine to make a carpet wand that is about half the weight of most stainless steel carpet wands. Replaceable air tight Delrin® acetal glide and ergonomic design allow effortless glide across any type of carpet.
