I'm sure that wasn't a Dyson produced video, but I must say, they make some good ones. And this one is too - adorable kid and cat. Almost makes me want the upcoming V8. Love my Rainbow, but I have pets and often vacuum before work. My Riccar Supralite is a great machine for ease of use / quick cleaning, but no cord would be even better. And there is something about seeing and dumping all the dirt after cleanup that is very satisfying. I'm sure that's one reason the baggless vacs have become popular.
Do hard plastic baggless vacs smell like bagged ones inevitably do as the bag gets full? No amount of adding scent or charcoal to the bad seems to get rid of all the smell. Nor do fancy filters. I've tried the best on offer and bagged vacuums still sometimes smell. Never owned a bagless like Dyson or Shark. I've always disliked Dyson because it is expensive and feels so darned cheap with all that creaky, hard plastic.
