Always the unpleasant cynic.
Many women (maybe a rare man as well) find fulfillment, satisfaction, and Simchas Mitzvah in cleaning their Bais HaMikdosh for Pesach.
In addition to, and maybe somewhat because of, the incredible tirchah.
Yes, all of it isn’t strictly necessary. Yes some of the cleaning is “merely” Hiddur Mitzvah and chumra and Fear and Love.
