They do have one for blenders at Espresso Parts. Here is the link to it:
I want one I wish they made one that could do blender containers too.
i use them in my both shop and really they are a must i use them for dumping milk aswell and really time saving it is not a hand washing station but just so rinse you pitcher so you dont have to wash them all the time. really handy as well to rinse shot glass .the only thing is that i recommend this one http://www.espressoparts.com/EP_PR6X24 i have both and this one is much nicer . you have room to let you pitcher dry.
We have one in our shop right next to our GB/5 and dipper well. It's a huge advantage and time saver. It keeps our shop dynamic of a clean bar easy! I highly recommend it for every shop.
Hope it works out for you.
I have one installed and love it.
We love ours too. Couldn't imagine working a rush without one. Jay's description hit the nail on the head. Like Patrick, ours is right next to our GB5 and in front of our Major. Great tool!
