Way behind on this but we finally got a robot vac. We got a "dumb" one that just goes wherever until it bumps in to crap. It works surprisingly good. We got the Anker one that was like $200. Would def recommend if you have a pet. Also, fired up the sauna for the first time since spring and it was amaze.
How long do you keep it running?
I actually saw one that was made for lawns recently. I think that would drive me insane.
I work downstairs and just let it bump around until it gets stuck somewhere. I know the places it gets stuck by now and just block them off. He just drives around and then goes back to the charger when the battery gets low. Its not perfect by any means, but helps keep up with the dust and hair from the doggie.
I have been looking at the lawn mower ones for a couple of years but can't pull the trigger. I was taking the dog for a walk a few weeks ago and saw one in action for the first time. It was super quiet. I had read that you could run them at night but was skeptical. After hearing it, you could def do that without bothering anyone. It was really cool. I really wanted to knock on the door and ask the people about it, but Mrs SF called me a weirdo.
