It may depend on whether you prefer to shower in the morning or evening, and personal preference. Most often every 2 weeks is suggested, but every 3 weeks is perfectly fine if you want to be a bit more relaxed about it.
I personally use the Tody to remind me when certain things need to be cleaned, and it has a setting for how neat freak/relaxed you are. I find that if I keep to a relaxed schedule I actually get more done because it's less overwhelming.
