I believe that we will eventually use robots for menial household chores but this may or may not be the gadget that catches on.

I have bought too many things that wound up just as you describe. Most of them were time consumers like exercise products and kitchen gadgets that did not work as advertised or they performed a service for which I found infrequent need. A coffee grinder was a recent waste of money by me.

I picture this product as being efficient for a single person or childless couple who have everything neat and in the right place. It seems unlikely that it would work well for untidy people or people who have children leaving toys laying about.

Another key thing is how often the thing's dust and whatever's contents must be dumped and how difficult that chore is. Replacing occasional vacuuming with a normal cleaner with a thing that requires daily attention is not a good trade off.
