I’m a recovering slattern who learned housekeeping as an adult.
On the way downstairs in the morning:
Make bed, tidy bedroom, pull curtains, open window. Pull other curtains, flush toilets, straighten bathroom.
One day each - hoovering/ mop and wet clean/ bathrooms/ laundry/ shopping & food prep.
Everyday - empty bins, clean cat litter, air house, clean dishes, clean kitchen, tidy the house for ten minutes.
When I hoover, I hoover everything - walls, surfaces, lampshades, skirting boards, curtains, cushions and even floors. I don’t mix dry cleaning and wet cleaning (mops, sprays) - dry always gets done before wet. Work top to bottom.
When I wet clean I spray every surface in a room, give it time to actually work, then clean everything off. It helps to work left to right and top to bottom (except bathrooms where you work from the cleanest surfaces to the dirtiest).
I do bigger jobs, as and when they make sense/I feel like it, which works for me. There are great checklists online if you prefer a schedule.
I put more effort into not making a mess in the first place (eg covering bowls in the microwave). Don’t put things down, put them away. I use liners in the bins and change them daily before they have a chance to split and spill so I only have to clean them down every six weeks or so. With Laundry, get clothes out of the machine/drier ASAP. Fold/smooth/hang while warm to minimise ironing. Throw a cup of vinegar into the rinse with towels and it keeps the machine running well.
Keep on top of clutter - if something doesn’t have a home address that. The more stuff that accumulates the harder everything becomes. Keep a donation box handy and keep moving things out of your house.
