Instead of working for a unionized cleaning company with a minimum wage, you too can be your own employer in the new app economy of toilet cleaning to order and be paid less, expected to buy your own equipment, and denied sick pay and holidays. But still subject to sacking if you don't put in 12-hour days, or get a sub-four-star review.
If the new tech is an on-demand market that hires a person to clean your toilet, the amount of manual toilet cleaning in the world is unchanged :)
