If you’ve seen the ads for a Dyson vacuum you probably wonder if they really work as well the commercials suggest. Actually they do. And unlike those lame Hoovers, which look like something my grandparents would have thought looked old fashioned, the Dysons are about as geek chic as you can get. And now neat freaks (like me) have new reasons to celebrate. The company is introducing a new canister unit — and not only a canister, but the first canister with constant suction. Available later this month for about $500, the DC21 features the same Root Cyclone technology, lifetime HEPA filtration, washable filter and foot-operated brush control! For those of you who only vacuum when you absolutely have to — like when you spin the chips on the floor – you’re in luck as well. The DC18 ($470) is the company’s first slim line vacuum, weighting on 15.7 pounds, but still offering the same super sucking power!
