All I needed to do was go to a hardware store and buy a $2 adaptor that fit on my sink. It basically screws onto your faucet and allows you to screw the hose end of the "Mr. Clean" right to your sink. Also you will need some silicone glue (also at the hardware store) and some duct tape for support. May sound complicated, but I am no good with building stuff and I was able to put this together.
