Product review (5 stars): Handy little appliance!
I was able to go to a local hardware store and purchase a shower head diverter, shower hose, a male plastic nipple that screwed into the lower end of the shower hose. I then used a small hose clamp to fasten it to the provided hose received with the washer. No I can flip the diverter on the shower head, turn on the shower and fill the washer. I was  quite impressed with how much I could fit in that little thing at once. I would say I could fit approx half a load of a normal sized washer with no issues. And the spin section does a great job at spinning out excess water. I set the spinner for 5 minutes, run cold water in there for the first 2 in order to to get rid of all the soap, then turn off the water at 3 minutes remaining and just let it spin out. Clothes dry within an hour or two near a fan. I have thrown 8 loads in the washer so far with no issues. Time will tell! Yes, the machine does require some babysitting, by then again, so does a public laundromat!
