So not true.
If the house is bid at $120 every 2 weeks and they want it cleaned weekly the price for anyone that is smart should be no lower than $105. Personally, I only give a $5 discount so it would be $115 if I bid it. It takes the same amount of time for a good cleaner to clean every other week as it does weekly. If it takes you longer to clean every other week then you don't have a very good routine down for cleaning weekly... in other words you suck at cleaning. The people that drop the price to $60 are the desperate, poor people. And even when I was desperate and poor, I didn't drop it to 1/2 of my bi-weekly price. You will find that if you have a $120 house and you drop it to $60 for weekly you will end up hating to clean that house.
