The 91684 package was developed at the request of contract cleaners seeking a back pack vacuum accessory solution that would allow them to utilize the superior power of back packs equipped for 1 ½” hose with the ease of use of 1 ¼” accessories. The 91684 is ideal for office cleaning, residential cleaning, cleaning retail spaces, and the hospitality trade. It is often favored over the bulkier 1 ½” accessories by female cleaning associates. The ergonomic handle which makes the transition between the 1 ½” hose and the 1 ¼” accessories is designed to reduce wrist and forearm strain and improve above the floor use of the provided attachments. The 91684 is designed for new or replacement use with all major brands of commercial back pack vacuum brands equipped for 1 ½” hose including Pro-Team, Mosquito, Sandia, Mercury, Hawk, Tennant, Karcher, Nilfisk, Perfect, Bissell Commercial, Carpet pro, Power Flight, and Carpet Pro.
