Query: Once again - another vacuum bites the dust!

Okay, we have a large house and 3 dogs, 3 cats, 3 kids - I was tired of having to pay $60 every time a roller went out - I bought this vacuum spending a lot more money thinking this should last past the typical 1 year - I haven't had this for more than a year and the roller keeps sticking - I clean the roller every month with all the traffic and hair but its another trip to the service center and another $60+ dollars - wish my money could be spent on a vacuum that lasts! I'm thinking about at Dyson - somethng has to be worth the money?!?
