By now there are many videos of robot vacuums covering areas. Its very informative. Not necessary to wait and see what a brand will do; just find a video and watch it in fast-time.

I have a Shark IQ which some videos rate as the best in the middle class. We have 1200sqft to cover and it can do about half that on a charge, methodically.

But it often gets stuck behind the AV center, or behind the piano, or wedged under my wife's chair or a certain cabinet baseboard in the bathroom. At least once a week. And with nobody home, the voice alert calling for help is pointless (scheduled to run when nobody is home).

So it just runs its batteries down waiting. If it could do one more thing better, I would say go into low-power when stuck?

Anyway we like it, gave it a name ("Puck") and each day check if Puck 'made it home'. If not its a pleasant job walking around to find where Puck got stuck. Not a bad purchase at all, considering the always-clean floors(!) and the entertainment value to boot.
