There are no instructions, but it’s self explanatory really. Just a tiny bit of detergent will do and it fits like 2 oven mitts or two kitchen towels or like 4 wash cloths. Or a number of washable mop cleaners. It’s very fast and efficient. Although the ringer doesn’t work. But I kinda knew that

I would give this a 4.5 if I could, only because I wish the basket was a little bigger, but it’s absolutely perfect for cleaning my cleaning rags. It washed my mop head, and I can get 2-3 rags in it at a time. Highly recommend!
