Laundry is definitely a pain point. You first have the chore of removing and subsequently installing fitted sheets, which are certainly not zero-insertion force. And the folding and sorting of the clothing (distributing towels to bathrooms, etc.) This requires enough seek time to at least hit each room once, and in the case of suboptimal routing, probably twice. In the case the laundromat, you have the carting of multiple baskets of clothes and materials, often down flights of stairs, into a vehicle, and at some distance. Materials experience spillage. A community (e.g. apartment complex) laundromat eliminates some travel, but your quarter supply may vary unexpectedly, requiring unexpected travel. This probably amortizes to eliminate the gain. In the case of doing laundry at home, you have both an infrastructure cost and a pipelining problem. Speaking for myself, I can rarely accomplish anything useful during a laundry cycle, leading to a near-total loss.
