I'm through disability unable to clean nowadays but I used to do regular deep cleans. Tidy first, everything should have a home.
Clean the windows
Cupboards, drawers, wardrobes, take everything out, clean the inside of the cupboard or drawer and separate items into 'going back' and 'throwing out'. Put unwanted stuff in bin liners for disposal put them outside so they're not in the way. Wipe the stuff going back before putting it neatly away.
Then hoover, including using the long vaccum attachment along the skirting boards and where the walls meet the ceiling. Run it along the curtains too. Move furniture to clean behind it. Don't just go round it. Get as much behind radiators as you can. Use long handled duster too.
Once all surfaces are clear and you've done your main vacuuming you just do one room at a time working from the top of the room to the bottom and going top of house to bottom of house. Begin by using an extendable duster to sweep across the ceilings, round light fittings etc to catch any spider webs the hoover may have missed.
Then onto damp cleaning (not polishing. Spraying polish sends as much into the air as it gets. Hot soapy water is all you need for this stage).
All your surfaces (including skirting boards, behind radiators etc) except ones that that you can't use a damp cloth on get wiped down. All ornaments get cleaned, dried and put back. Any surfaces that need chemicals eg bathroom, use those instead of the hot soapy water. Go back over everything you've damp cleaned with clean warm water (no chemicals) and dry with a lint free cloth. Finish with a final vacuum or mopping depending on what flooring you've got and you're done.
I'm sure there's things I've forgotten but that's basically it
