Cordless Hand Vacuum

I have a rechargable 4.8 DustBuster Wet / Dry and even being in the charger all the time I only get a few minutes of sucking time. I know I need a more powerful but want one that works for a longer time.

DeWalt DC515K Heavy Duty 1 / 2 Gallon 18-Volt Ni-Cad Cordless Wet / Dry Vacuum

It really sucks! It beats all other vacuums I've owned wireless hand. This is not a replacement for a cordless vacuum real, but nothing will ever beat a plug in the vacuum.

I have the ACC "cone" that is advertised on television. I've never had any problems with it. But if you go to a hardware store you might find something made by Black and Decker. They are very reliable and the items I would not hesitate to buy something made by them.
