I am writing a follow up review from a few months ago after I had this machine for a few weeks. I'm still not happy with this purchase. Main reason, I had never used a washer with the impeller and I won't again. Clothes don't clean as well as they do with an agitator. The clothes are basically being gently moved around like a lazy person hand washing clothes. Granted with the impeller you can wash an item as large as a comforter but I wish this had the option and ability to have the agitator and for it to be able to be removed so you could also have the impeller for larger items.
Plus, it doesn't have a prewash or soaking selection. 
And one other thing I wish it had, when I pour my detergent from the cup to the dispenser, I wish you could start the water to be able to rinse the residue in the cup to remove the rest of the detergent and pour it into the washer tub.
