someone once asked if the hydro sweep outcleaned the cast iron kitchenaid wash arm.Definately yes.In 1964, KitchenAid unabashedly proclaimed that the four way hydro sweep was as far ahead of the big blue lifetime wash arm as the blue wash arm was ahead of competitive,inefficient impeller type systems .They said that it provided more power,more velocity,more concentrated cleaning power to every dish and pan,setting new standard in washability.My own tests over the years have verified those claims.But with today's high powered enzymatic detergents,the gap is not nearly as high and if the food has not dried on,the difference is negligable.

I have a 1965 KAid KDS-15 Superba. Like all the KAid single arm "Hydro-Sweep" machines I have used before this one it cleans beautifully. Now, laws of physics being what they are and all that, I have always been able to "pack them full" of dishes, including large items on the lower rack, and everything always comes clean. I almost always buy the cheapest detergents, "Big Lots" brand is one that comes to mind. So I think something can be said for a really good design. I've used many different machines over the years with all kinds of spray arms, but none has ever done as well for me as a plain old KAid.
I think the newer detergents, even the ones before the current crop of enzyme products, boosted the cleaning power of the older machines quite a bit. I'd be willing to bet that the new detergents would boost the cleaning ability of the old impeller machines of the Fifties and early Sixties to the level off at least the Seventies machines.
Comes to the Rescue!
