In what part does it read like sarcasm?

Also i know, i own one and use it in my bedroom, but in what way does this post fit this sub?

Edit: okay i can see it now. But what i mean is you can't expect business going the suboptimal way of using a robot to clean such a small space while their employee can do it in 5 min. If the supplier didn't come with a free sample unit then the owner will have to pay for it themselves. And this is at most an irony, but nothing dystopian about it
