Love Stardrops! It lasts approx a million years ...
That video was really interesting - and for a change, the comments are pretty much relevant. The plunger seems to be the most universally approved of, and for a change, I actually have a plunger already, ready to drill

. The buckets don't seem to be popular - I wouldn't plan to regularly lift anything that heavy in any case, but there were comments about the painful wrist action when draining, the dirty bottom bucket being put on top of the clean clothes, the jagged edges of the holes in the bucket sides ripping clothes, the water going everywhere, the faffing with the lid but not actually using it in the videos.... but the plunger with holes in is brilliant, and it can be used in any container. Exactly the same sort of object can be seen in any museum with
19th century domestic laundry items on display- I tried to link, but the links are 6 lines long, for some reason. Do an image search for those words in bold if you're interested.
I've been a bit concerned about laundry in any grid down situation, but that plunger is gold
