Review on Black Decker PVF110 Filter PHV1810 by Charlie Conner

Uh, you don't think about it, but just emptying the dust container is not enough. The reason I couldn't get more minutes of run time is because the filter needs to be removed and yes I shook it out but couldn't clean it. As soon as I replaced it with a new one, the suction power increased and it lasted longer. Great medicine!
