Cleaning techniques?

Okay so this feels a bit silly but I feel like I never got a good sense of how to do basic cleaning? Like I am bad at sweeping? If I'm cleaning a bathroom I feel like I'm not certain on the order to do things or etc. it always feels harder than it should?

I know there's lots of how to clean resources out there but I also know there's some suspect advice and I don't want something that's trying to just sell me gadget either. Any suggestions?
