A side note: cleaning any of our tents is easy. Remove all your gear that you want to keep - sleeping bag, pad, etc. Double check those mesh pockets in the tent, for eye glasses etc. Leave a door unzipped with flaps tied back; tip up other side of tent so open door is down, and jiggle the tent. That dumps out nearly all of the sand, pine needles, and loose pocket change.
If you want it cleaner than that, DO NOT use anything that resembles a whisk broom. That builds up static electricity and all remaining dirt is held magnetically captive. Instead, dip your boat sponge into water, squeeze it out, and use the damp sponge to wipe the tent floor clean.
I realize that all you experienced geezers already know all this. But, once in a while a tender foot wanders in here.
