I have 2 labs and used a Shark robot for years until it finally burned out. I found it picked up a lot, but it also left a lot; so, I was *almost* always manually vacuuming afterward anyway. If I were to get another one, I'd make sure to take it apart regularly to clean the dog hair out of the wheel gears (which was a huge pain to get to) - because dog hair in the gears is what eventually burned out one of my wheel motors.

In short, I don't really miss it. It was okay while it lasted; but, I'm pretty sure that were I to commit to doing proper regular maintenance (especially with a couple of dogs), it would render it more trouble than it's worth.
