Not sure if this is obvious from the title or not, but for many years I have been impressed with how my entry-level robot cleaner manages to cover the whole apartment by cycling through a few simple "patterns" (follow wall to left, turn at random and advance, etc). More recently, I'm impressed with how well my bread machine manages to mix and knead bread while having only one small paddle that rotates in a single direction at a single speed - despite that, and whatever consistency, it does a decent job, with the dough apparently moving in a chaotic / random manner.

If that makes sense at all, what are other examples?
