If you are considering buying the CTX Water vacuum I recommend doing it immediately. By now, we have all seen the black water left in the canister after the first use. Yes, it is disgusting. I almost didn't leave a review because of how dirty my water was after the first use. Even worse, there was so much debris pulled out of the rugs and floor, that I could not empty it into the drain or toilet. I was a afraid it would clog the toilet. I emptied canister into a strainer so the debris would not enter the toilet. Below is a picture of the stuff I emptied into the strainer. None of this was visible prior to vacuuming. Evidently, there was a rubber band embedded in the rug. This is embarrassing, but impressive! I highly recommend this vacuum.
