I love it! I'm the same, got a cat and two big hair-dropping dogs, plus loads of horses and we always bring in dirt, straw & hay from outside, we don't have time to vacuum several times a day, so this just does it.
It doesn't do a 'wow your house is so clean' job, it just makes it presentable and less daunting when you come in! Still do a proper Dyson job in the evening, but we've noticed it doesn't take half the time as it did!
I'm recommend this to anyone! It even charges itself when it gets low on battery! And you get a remote so you can sit on the couch and drive it around like a toy car!
