A user’s Black & Decker CHV7250 Wet-Dry DustBuster vacuum review says: “The Black & Decker CHV7250 Wet-Dry DustBuster vacuum is a great little machine to pick up small debris and dust. It has really great suction for being so small. It’s also nice to have rechargeable batteries instead of always replacing them. To recharge it, you just plug it straight into the wall. A cradle would be nice at times, but it’s manageable to just plug it in. It’s also not a bad price for what you get.
On the downside, it needs recharging pretty often. Also, I hear that it doesn’t last super long – it has about a year life span. It gets scratched pretty easily too, so don’t expect it to look all nice and pretty for long. If these things don’t bother you too much, the Black & Decker CHV7250 Wet-Dry DustBuster vacuum will work wonderfully for you.”
