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.
