There are a number of "cleaning challenges" which are really just conscientiousness or process problems.
"It's difficult to sweep the house"
- Often, this just means that the house is too cluttered. You own too many things, they're not put away, and so each time you need to sweep the floors, you need to spend time organizing first.
"The fridge is always getting dirty."
- Only clean things should be put in the fridge. If your shelves are dirty, it's because the bottom of the items you're placing on your shelves are also dirty. Do you let ketchup run down the side of the bottle? Is your counter dirty, and you've set a clean bottle of salad dressing on a dirty counter? In both cases, you have transferred dirt and/or oil into the fridge on the shelf. And then this compounds multiple times: do you always put the ketchup in a different place? Well now you've spread around the dirt. Do you clean the fridge but bot the bottom of the ketchup bottle? Well, now your clean fridge is immediately dirty again the moment you reload it.
- etc.
So many "messes" in the house are compounding problems; the worse you let it get, the bigger the problem you've made for yourself. Didn't put away the kid's toys? Well now you can't sweep that area. Can't sweep that area? Well now you can't mop that area. etc. One solution, which people might not think about with regard to cleaning would actually just be to make sure the kid has fewer toys, or at least fewer _available_ toys. If you nail this, the clutter --> sweeping --> mopping cascade starts improving without any additional work on your end.
