Weighing in at a whopping 30% lighter than most commercial-use-rated, cordless-upright alternatives, the HVRPWR™ 40V cordless vacuum is guaranteed to be more mobile and easier to use in just about every scenario. As it's conveniently powered by the universal HVRPWR™ 40V battery system (sold separately), if your janitorial or housekeeping staff should forget to charge before use, it's a snap to swap out the battery for a freshly charged one; and as all HVRPWR™ Commercial products are powered by the same battery system, there's never any confusion as to which battery goes to which Hoover®. As luck would have it, the battery only takes 60 minutes to complete a standard charging cycle, which matches the vacuum's standard run time. By the time you're running low, your team can have a spare ready to go. Quick-Pass Cleaning system delivers the ideal combination of power and performance to help users clean more efficiently. HUSHTONE™ two-speed motor provides a HUSH mode to minimize noise around your clientele and a Boost mode to enhance performance when your staff is free to do a deeper cleaning. Convenient auto-stop feature automatically disengages power to the brush-roller and motor when you lock the machine into an upright position.
