Sorry, there was a problem. Please try again later.The Shark BU3521 vacuum features a click-on/click-off power button, so you do not need to hold the button down while using it. Once you press the power button, the vacuum stays on until you press it again to turn it off. This makes it more comfortable for longer cleaning sessions, especially compared to models that require continuous pressure on a trigger or button.
