And that's good for you, but other people is willing to pay other amounts. You own purchasing power affects what you are willing to pay and it makes sense. If your think that it doesn't, well, let's just agree to desagree because that debate is out the scope of this thread and we both are pretty sure about it.

About this:

"So let me turn this around on you. I think you're confused here. Just because you're only willing to pay $1000 for a robot it doesn't mean that is what it would be priced at. "

Sorry, but I'm not confusing this. You are right, it doesn't mean that. I never said it did.

I don't really want to enter the debate of the logig in the tasks and limitations of the level 1 robot, I mostly agree with you that the op makes no sense on that...

And yes, they might rent it. But the new price would not be the previous maid price, that's the assumption that doesn't make sense. New price would be cheaper and dependant on the price (not willingness to pay) of the robot. Can you profit with that? Sure, maybe you can. But you are not getting your money back that easily. Why? Because it can be done per robots. If it was that profitable the price for the robot would go up.

And well, given the description of the robot I don't think that it would be easy to rent because it doesn't seem to be capable to move alone around the city, but that's another story....
