I do eight an hour at ease, maybe nine at a rush. The thing is there are so many types of 3 bed semi's. One of my round's is extremely compact, almost every house is just next door to the last. The houses are of the Wimpy, Beezer Homes type. Small window's in every room that each take no more than a few second's to wash. A typical house on this round with nine smallish windows will take me just about six minutes.
Now I have been doing this particular estate for 16 year's, so I aint doing it wrong.

No one on this round will expect to have to pay £10 to me or any other cleaner for that matter.
They will however pay £4.50. Now.......go figure the tenner a house brigade.
