Former lazy with the housework person here
Are all of your rooms currently clean and tidy? If not the way I went about it was to completely tidy, declutter and clean one room at a time, took about a full days work on each one, going through cupboards and putting things where they belong, cleaning skirting boards, windows, basically a full top to bottom deep clean. The next day I did upkeep work (so hoover, mop, dishes, surface wipe, bleach down loo over night) in that room then fully cleaned the next.
As each room was cleared that was added into the routine.
Now my upkeep only method is as follows
Daily
Laundry put on first thing in the morning - have coffee and breakfast while it’s running then hang to dry
Dishes done and put away
Anything visibly dirty (tiles, sinks and so on) cleaned up - normally only one or two small areas each day
Surfaces wiped with zoflora (kitchen counters, windowsills, tables)
Litter trays and animal enclosures spot cleaned ( we have 7 pets, much easier to do a daily spot clean rather than clean up the mess just once a week)
Run the hoover and mop around all rooms
Put bleach in the loo before bed
Altogether doesn’t take much more than an hour
Weekly
Sinks, toilet, shower and outside of appliances wiped down or cleaned
Skirting boards / doors / doorframes cleaned
Windows cleaned on the inside
Tv dusted
Hearth cleaned
Animals cleaned out completely
Monthly
Fridge cleaned inside
Carpet cleaner on the carpet
Cooker cleaned
Inside of cupboards wiped
I think I have got everything there, might be a few things I missed but my method is to just spread out the weekly / monthly jobs over time so it all gets done before it looks bad, and the keeping on top of it means the work is very quick - I spend maybe an hour on the daily jobs and half an hour on the other ones, ticking off as I go. It’s so much easier when it’s kept on top of and means you don’t have to do the once a week mountain of cleaning I used to end up with.
Also work smartly - if pans need soaking put them in the sink but go do something else while you wait, bleach down the loo daily means the weekly clean is just a once over, make life easier for yourself whenever possible and just do things as they are needed. If you haven’t got round to something on the monthly list but it obviously needs doing, get it done there and then, rather than put it off an potentially forget.
