Our MILWAUKEE 9′ Accessory Hose works on the M18 FUEL 3-in-1 Backpack Vacuum (0885-20, 0885-21HD). At 9′, it is longer than the stock hose for extended reach in multiple applications. The pivoting joint reduces hose kinks than can cause hose damage over time. An integrated belt clip allows you to secure the hose while accomplishing another task and provides a place to store the hose while the vacuum is stored.
