We used to be Dyson fans. The operative word is "used"...
We started having trouble with our Dyson and got zero help from the factory (they wanted to do the repair as opposed to just sending me a part that I was even willing to pay for). I started looking around for alternatives and stumbled upon the the Shark Rocket series of vacuums. We bought the Rocket Pro to use in the sticks and bricks and for a test we used the Dyson first and then went over the same area with the Rocket. Amazing how much more it (the Rocket Pro) picked up (the only problem with the Dyson was a broken latch...didn't affect its vacuuming ability). Sold the Dyson in a yard sale...we have 3 cats, two long hairs, so, we're familiar with animal fur. We bought the regular Rocket to use in the 5er and are quite happy with the versatility, quality and effectiveness.
Shark Rocket VacuumsThese aren't cheap vacuums, but, they, for us, are better vacuums than the Dyson and, though not cheaper by a lot, they do cost less than the Dyson units.
