Our apartment complex, the Redwoods, has cages on the roof where the laundry equipment is located.  We pay for the water and electricity which we use in our cage. First we use the agitator on the left, then drain the wash water and fill the tub with rinse water and agitate again: then put the laundry in the right side where it spins. After we spin it, we hang it up to dry.  It is very hot up there.  No breeze can be felt and we usually go back down to our apartment dripping with sweat afterwards.
