The Black & Decker PV1820L-QW is the replacement of the PV1825, one of Black & Decker's best-selling handheld vacuums. There's a reason this handheld vacuum is so popular: it's a lot quieter than most handheld vacuums and also a lot easier and more hygienic to empty. You simply empty it by opening the side door and emptying it above the trash can. Don't think that this handheld vacuum gets full quickly. Since it uses a special cyclone technology, it has up to 40 percent more capacity than the original Dustbuster Pivot. In short, the Black & Decker PV1820L-QW is very easy to use.
The PV1820L-QW differs from the PV1020L-QW because of the 18-volt Lithium battery, which gives the PV1820L-QW greater suction power. The PV1020L-QW has a 10-volt Lithium battery.
