Pretty sure it's because you could have a fixed "sweep every cell" approach that would work in the previous problem (while being inefficient and relying on checking the whole grid instead of detecting where the next item to clean is), but if you used Manhattan-style heuristics, you would have a solution that outperforms what was expected in the first one and that would do fine here.
