[Futurama] What wer some of the more absurdly specialized robots, such as Hedonismbot, originally designed for?

It seems unusual that anyone would ever need to order a robot designed to lie around like a Roman emperor and act debaucherous. 

Also, if they were created by Mom's Old Fashioned Robot Factory, why does there seem to be so many one-of-a-kind robots? it seems as though it would be very expensive to create and build a single robot of a design.  Or is there another, smaller company making them?

In answer to your first question, hedonism bot was designed to add flair to rich people parties. He's a piece of entertaining furniture that they could all laugh at and a great conversation starter.
To answer your second question, they aren't one of a kind, you might think they are because there was a limited run of robots in that series but they are all mass produced. Look at Bender and Flexo!
