The corgi in the second video seemed to be a little more enthusiastic about it than the spaniel in the first one. Judging from the position of Freckles' tail, she wasn't really enjoying being vacuumed all that much, but was cooperating out of a sense of canine loyalty and obedience.
I'd love it if my cat would let me vacuum her, especially when she's shedding in the spring and summer, but I've never been able to even try it; she barely tolerates being brushed. She runs and hides whenever she sees me get the vacuum out, but once I get it going, she will often creep back into the room and maintain a discrete distance, just to see what's going on. The cat I had before her wouldn't even do that. She would stay hidden for a couple of hours after the vacuum had been turned off and put away, just to make sure.
