Goons never die, they just go to HN and regroup

This is how I used to solve the roomba-can’t-use-stairs problem.

I’ve now moved to a single floor. Problem solved!

Then they can't bring anything up or down the stairs.

Still, I expect it won't matter - by the time we have reasonably priced robots that can reliably do all housework, that's like 90% of jobs eliminated from society and probably society will collapse.
