Further, backpack vacuums also reduce body stress associated with vacuuming because they minimize hunching over due to pushing and pulling which is often associated with upright vacuums. With a backpack vacuum, a cleaner’s repetitive motion also incorporates side-to-side strokes as well as back-and-forth ones, yielding even more ergonomic benefits.
And since backpacks allow for a natural range of motion, users don’t engage in the repetitive motions that can cause a repetitive stress injury. In fact, cleaning personnel are able to vacuum in half the time because they are able to clean in a natural walking motion.
When implementing backpacks into a cleaning program, however, users must wear the units correctly. The weight of the backpack should rest on a cleaner’s hips and shoulders. Most backpack units have an ergonomic back harness to reduce injury and to cut down on back strain as custodians clean.
