I have learned to ignore pet hair. My housecleaners come every two weeks and do a great vacuuming job and I don't do anything else. Oh if there are "tumbleweeds" of cat hair I do pick those up by hand.
I housecleaned for a living for several years part time and I was forced to clean my parents' entire house every week when I was unemployed and living with them. I swore that, when I could afford cleaners, I would never, ever, ever clean again.
And Dyson vacs rock! I did a house sit with two golden retrievers, a long haired and a short haired cat, and I had to vacuum. I couldn't breathe after three days of all of these pets shedding so I used the Dyson. Awesome! Totally worth the gazillion dollars they cost!
