If she wants a pet that pretends to clean.. then sure.. they are good for surface dirt but that is about it. I'd give her a new vacuum that YOU want to use and say instead of a Robot, you got a husband! She'll be much more pleased with the results.
Yeah!! They will be good gift to you wife as she can do daily chores of work fast and also make house clean and dirt free with cleaning robots but they require high maintenance. So, be careful about it.
Simply buy it.
She wants then forever she gets.
No reviews from board members of Google searches.
Make her smile it will be worthwhile.
