While the goal is to get 10 minutes per day the discussion of if it can be done in a mall should probably continue. I know several people who go to the mall not to shop but to walk as it gives them a public venue protected from the elements and sometimes and element of safety. If you are walking and window shopping perhaps the answer is no. If you are there and moving your way past the windows for 10 minutes then perhaps it actually does count.
Again, while the goal is to fit it in...ultimately you have to decide where, when and the exertion level of the exercise. Lots of article on what it takes to count as exercise (elevated heart rates etc). As for house cleaning - I agree that it perhaps shouldn't count as exercise but there are ways to add a level of difficulty into it and challenge yourself like walking lunges while vacumming etc.
My random 2 cents.
