They are fairly quick and easy to service. There are some slight differences between different stores' model specs. Sears models and Wal Mart models usually have wooden brush rolls- Target and Kohls usually have nicer brush rolls, it all depends on the requested wholesale price from the store.
Service wise- they are as easy as they have always been. Nothing really new to service. I think it takes about 30-45 mins of high school labor to have one looking like new.
