Cleanliness is next to Godliness if you're trying to maintain your conditions indoors. Dead leaves and trimmed leaves left on the floor begin to break down and rot, or worse mold if you're letting your water overflow collect on the floor. It's also like a Golden Corral buffet for bugs.
Get in the habit of doing some room maintenance at least once a week, where you can lightly sweep the floor and take a hot wash cloth to the floors to scrub any stains left by nutrient water, scum, etc, and then scrub the walls. If you're spraying in your tent with any sort of product, there's going to be some residue left behind (can create a film on your grow lights as well.)
I'll give the same speech I give to my kids when it comes to cleaning, "in the amount of time it's taking you to BITCH about how long it's going to take you, you could have been already halfway done."
