Wierd as this sounds, it is neither big nor small. The lid, which is a strange glass in the middle but steel on the outside affair, is the size of a very large pan, like one of those big Farberware pans.
There's a big Kenmore microwave behind it, kind of out of sight, but you can see the comparable depth compared to the unit.
You would have to do more than one load to do a meal clean up for say, four people. I just put a few dishes in and a few cups.
To be honest, I was hoping for an expectedly cool water turbine jet sound, but it really just sounds like water spritzing on the inside of a steel bucket! But there is some whirling noise of the central unit.
My wife actually got this, and when I received it, I was not sure if I liked it, tolerated it, and it kind of creeped me out (some older stuff just does that to me. I could never have a wringer washer, can't explain it).
I was thinking if there is interest, and the site owner would like to see it, I could make a video of the thing. It certaintly is oddball.
Maybe a combo video of my American Kitchens Roto Rack dishwasher and this unit.
