Combination of Flylady routines and The Organised Mum Method (TOMM) saved our house!!
It's quite a lot per day (to me, anyway) 45 minutes - one hour. I don't manage that every day but as PP said, if you do 15 mjns a day, that helps so much.
There's a great TOMM website/app/ FB group for more detail but very briefly, idea is you split tasks into levels one, two and three:
L1 = 15 mins daily tasks - make beds, load of laundry, hoover high traffic areas, one thing in bathroom each day and rotate.
L2 = 30 minutes on each space- Mon - living room, Tues - bedrooms, Wed - hall, stairs and landing, Thursday - kitchen
L3 - Fridays - 30 minute deep clean in one of eight areas. This changes each week.
Been doing it about two years and it gets easier over time. Setting a timer is very important. You are meant to stop once timer goes off and pick up on it next time.
Things like washing up are not included in the time.
Love the ticklist on the app. Takes away a lot of mental load.
