Of course they aren't the same, and all your statements are true, and "Uber for Food" also isn't the same, but the ultimate challenge will be the logistics problem (they admitted that their ultimate problem was logistics), and this problem is equivalent for all three. If you solve this problem for Food, you can beat Uber, beat anything else, just on this one algorithm, or you can offer your algorithm to Uber and other services.

Problem can be defined as pickup and delivery, on the fly, or offline (knowing all of the orders in advance). If you solve the on the fly, you've solved the offline problem. Picking up people, or food, delivering people, or food, problem in its essence ignores the subject and optimizes the pickup/delivery.

Uber for food is logistics. Cleaning is trust.

I would argue that a recommendation engine would be a far better thing for cleaning services than a logistics solution is. Facebook are a lot closer to the solution for cleaning services than uber is. I want a cleaner who people say are trustworthy and who is reasonably local. I want a driver and food delivery guy who is very local and somewhat trustworthy. Very different domains.
