Product review (4 stars): Doesn't have the convenience of a regular washing machine but it does save you quite a bit of money and time!
Works surprisingly well!
The reviews I've watched all use liquid detergent but I have this huge thing of powder detergent that I got before I purchased the Wonderwash. At first, the powder didn't really disintegrate and would come out all caked onto some of the clothes. :( But then you just get the extendable shower head and hit the soap straight on and there solves the problem. :)

Any stains you have you should actually try to remove before you wash it in the Wonderwash.
We also have the Nina Spin Dryer which you should get with the Wonderwash. After your done washing, the clothes of course are soaked. The spin dryer will spin your clothes around like a salad spinner and make it just dry enough so that your clothes are good to go in a few hours. Best if left to hang out to dry overnight. :)
