A friend of mine has a KitchenAid dishwasher that she simply loves. I honestly can't give you much information but she says that it really does the job, she doesn't have to hand wash any of the dishes or pots and pans before putting them in the dishwasher.
Many years ago, I purchased a portable dishwasher when I was working, going to college and had 3 teenage daughters to raise alone. I felt that the dishwasher would help free up some of the time that I was spending doing this particular chore, since rounding up my daughters to do the dishes was a constant hassle,

. After having the dishwasher for about a month, I found that my electric bill was much higher than I expected, my water bill went through the roof, and I couldn't get my daughters to unload the dishes

. I took the darn thing back to the store
