There is one exception - the robo-vacuum. It's good enough today to run 99% unattended (you still have to empty the dust bin by hand and clean hairs from its wheels). It does a more thorough job than a human already.
We've had a Rumba for some time. In the early days it was used regularly, now almost never. I don't know why, but I find that 5 minutes with a manual vacuum achieves a far better result than watching the Rumba bash it's way around the room for 30 minutes or more.
I’ve found the wireless vacuum (eg Dyson) to be even better: you just pull it out, vacuum, put it back. It’s more powerful than a robovac and, without cord fussing, incredibly low overhead.
