Dirt Devil 15.6 volts
I know a vacuum cleaner isn't the greatest Christmas present but if DW asked for one, get her one (and save the receipt so she can return it if it doesn't perform to her satisfaction). With that said, I am on my second Dirt Devil 15.6 volt rechargeable Accu-charge vacuum. I use it on carpet here in the house and in the TT and although it doesn't fluff the carpet up like my Electrolux does, it does a great job of getting the dirt sucked up. My first one was given to me, the second I bought at Overstock.com. It was about the same price as a new battery. When this battery goes, I will probably go to the place that just sells batteries and buy a replacement as I think they are better, longer-lasting batteries. Love my Dirt Devil. In between the 2 rechargeable Dirt Devils I did buy a corded one. Didn't take me long to return it as it had no suction at all!
