I don't know.....
Washing a blanket would be quite a choir. Wringing the heavy blanket before the rinse, then wringing again, unless you have a spinner or wringer clamped to the sink. There is going to be water splashed and now you're standing in water with an electric vacuum cleaner that wasn't double insulated back then, I'm going to pass.
It would be fun for a toddler to have his/her bath in a sink percolating with bubble bath. Maybe run a longer hose so you could locate the cleaner further away from the festivities!
