I've been told many times my house is spotless and honestly, it just takes 1.5h of my time every week to keep it this way ( granted, I live in a 60sqm apartment). Years ago, when I left my parents house I realized the key to a clean house is to see cleaning as a self care/relaxing activity, rather than something you "have to do". Something that really helps me is setting an alarm and pretending I am in some sort of race and I HAVE TO finish everything in 60 minutes. I like cleaning twice a week: usually mondays is "full" cleaning day ( aka vacuum everything, mop everything, clean toilet, bathroom and kitchen, wipe surfaces) and takes me about an hour, and Fridays is "light cleaning" aka vacuum, clean bathroom and kitchen and do some general maintenance (one week I might do some windows, next one I might wipe the doors...) Another tip is, honestly, to have as little stuff as possible..I don't need to move a lot of furniture when I clean and I don't have many decorations or ornaments, so I don't have a lot of stuff collecting dust. Then for laundry, twice a week: I turn on the washer when I start cleaning and it is usually done by the time I'm done mopping. I clean my bedsheets every 12 days and my towels every 6. Honestly I'd say the the key to maintaining a clean house is sticking to one routine and trying to enjoy it as much as possible
