Whether space, cost, environmental concerns or other reasons have you looking for other detergent solutions, Robby Balls are definitely an innovative product to consider. Each ball is filled with a year’s worth of concentrated detergent pellets and the balls can be refilled and used for 2-3 years. Compact, affordable, and easy to use, the only fall back is that you will have to remember to remove it from the washer and I do not recommend using it with cloth diapers, because it is lightly scented and I am not sure what the macro-molecules are composed of.
I definitely trust its cleaning power more than other similar products I have seen on the market, my laundry came out fresh and clean, and I love how little space it takes up in the laundry room. I like that it is phosphate and chlorine free and that it includes a stain stick which they encourage you use in lieu of bleach or other harsh cleaners. I reviewed the blue Robby ball which I tried on both colored and white laundry with success, although I think there would be advantages to having both balls if you plan on switching completely to a Robby Ball system.
