We never saw Cliff’s nurses or reception/bookkeeping staff either, so given that even full time staff didn’t make it into the show I can see how a part-time maid wouldn’t either.
But they had five kids. Cliff and Claire were the types of parents who would insist on the children doing their share of the chores. They were good parents who made sure their kids learned to be responsible.
Yeah, but that house was spotless. I have a hard time imagining Cliff and Claire would be able to get the kids to dust and clean the top of the fridge and keep everything as nice as things were in that house. They had a hard enough time just trying to get their kids through school and not going off on harmful tangents in their social lives. 
Originally there were only four.
Also why did the Jeffersons need a live in maid when they had a small NY apartment? I guess they just needed someone for George to argue with.
Well, yes, in the pilot there were four. Oldest daughter Sondra was added once the series got underway, though. Cosby wanted to establish the Huxtables as successful parents by having an eldest daughter attending college. Still, four kids would have been enough to be responsible for keeping the house clean.
They didn’t need one. In fact in the beginning it was a battle with Louise NOT wanting a maid and George insisting now that they were rich, Louise needed a maid.
There was even an episode where Mother Jefferson agrees Louise does not need a maid (thinking Louise wants one). Then when Mother Jefferson finds out it is her son George who wants one, Mother Jefferson replies “Well I could understand how George would want someone to keep the house clean.” Implying Louise doesn’t do a good enough job.
Then at first Florence was a cleaning woman that didn’t work full time. Only after awhile did she move in as a full time maid.
They had an episode where they show Alice’s room. It’s a typical maid’s room off the kitchen, as was Hazel’s room and the maid’s room on Diff’rent Strokes
he was a band leader for about 15 years before doing radio. his being a band leader was mentioned though infrequently on tv. i don’t recall it on the radio shows i’ve heard (i’ve heard only a small fraction of the hundreds).
the real kids were not on the first 5 years of the radio show.
Was it ever specified where the Cleavers lived?
Mayfield, of course. Not far from Springfield.
