Great Pyrenees Shedding

Great Pyrenees dogs are big, white, fluffy, and shed a lot.  Various websites recommend Dyson or other high-end vacuums to deal with the fur load and a lot of people have tales to tell of other vacuums that have been done in by the beasts.

Shedding is indeed an issue--shown below is before vacuuming:

and after:

I don't have a particularly high-end or capable vacuum.  I have a Hoover self-propelled Wind Tunnel with a bag.  After a few months of cleaning up after the dog--the picture at the top is after just two or three days, but can easily happen after just a few hours--I noticed the vacuum's performance was declining, though the bag wasn't full.  Then the drive belt broke.  I flipped it over and saw the problem.

She has a lot of long fur in her top coat.  Some of that wrapped around the spinning brush, and over the course of a few months, completely jammed it up.  Removal was accomplished with a box cutter and about 20 minutes' work (using the cutter carefully to avoid cutting both myself and the roller).

I have gone through both bags and belts more quickly than in the past--Amazon sells 12-packs of replacement belts relatively cheaply--but for now the vacuum is holding up and works relatively well.  I clean the roller after every four or five vacuuming sessions.  I'll step up if I have to, but otherwise, the nearly 20-year-old vacuum is continuing to work.
