Piece of junk
I work in grooming at a pet store and do some grooming on my own.  This product was priced at $50 - $60 in the store. Recently they were on clearance so I decided to buy one. Paid about $30 with the clearance price and my discount. What a mistake!! The soap doesn't come out, if it does you certainly can't tell.  I opened the handle where the cartridge is and had to push down on the cartridge to get the soap out, and even then, it's very little. I changed cartridges and had the same result.  What a waste of money! I end up washing the dogs by hand.  I suggest anyone looking for this type of shampoo system to check the one that's an "As Seen On TV". I purchased it for around $20 and it works far better. You have to pour 1/2 shampoo, 1/2 water into a compartment. No cartridges but for the money, it's great.  Works better for small dogs.  Wish I could get my money back on the Hydrosurge but I doubt it since it's on clearance. No wonder they aren't carrying it anymore.
