People who utilize the services of a cleaning lady (or "maid service"): How much do you pay her, what does she do and how many rooms does she clean?

I am just curious what others may pay their hired cleaning help, and to get an accurate comparison i think telling the number of rooms would be helpful. Also, i am curious what exactly she (or he or they) cleans or does for that money. Does she do laundry? does she put away clothes? Please be specific as possible.

I have had a cleaning lady for a little more than a year, and as someone who did not grow up with this type of service, i have no experience knowing what to expect or if i’m getting the right amount of help for what i pay.
