Would an affordable service robot be an item worth having at home? What types of tasks would you want it to do/?

Yes, it can do my floors,laundry,make the bed and do the cleaning of the bathrooms and maybe some cooking...:and I'll just sit here and watch...:)

I would like to have one to do the carpets and windows, but, affordability is the question, "affordable for whose pocketbook?"

yes would make my life easier like doing regular cleaning of the house

Yes. I would use it for, *ahem*, "services".

Dusting, and cleaning the windows.

Affordable service unit??...a little vague if you ask me...what service does it perform

I think I know where this is going.
