My trusty Dyson, that I loved and did not want/need to replace, has a huge crack in it of unknown origin. I'm pretty rough on things so I take responsibility, sure have no clue what happened though. It's a crack that is not repairable, sadly. I like the Dyson and would prefer a new one, but am having trouble justifying the cost. Anyone have experience with the new roller ball type system Dyson has? Worth the cost? How about the purple/pet version? Does it really work better on pet hair? I'm also looking at the bagless Hoover, it's a lot cheaper but not sure if the quality is similar. Taking input on other brands as well, so if you LOVE your vacuum, tell me what you have. I do have indoor pets, I have carpet and slate flooring (hard tile), have stairs, and lots of dirt, so I need reliable, sturdy, and changeable surface options. I prefer bagless but could be convinced otherwise.
