Honest question here ;-)

I've wondered how an AI stain detector (in such a robot) would work on my porcelain tile floor with faux olive wood grain & slight texture. 

Mauricio, have you relevant experience using this Dyson device ? 

How good are they? 

Meaning does it do what it says on the tin?

They are good and they do it well. I am actually doing a full house pass at the moment.
