EXENSIVE.
Have seen a demo but demo's are controled, never seen it in a true work enviroment.
Have seen others and own a Water Treatment Technologies system.
It works off electric, Little Sucker needs an air compressor to work it.
Then the Water Boy, a copy of what I have, have heard the two are related, family wise but not sure and don't care.
Little Sucker I believe has less maintenace then mine, less innards to keep clean and that is a plus I admit.
Cost is a big difference, Little Sucker cost a ton more, but the results are the same, they are designed to help remove petroleum type oil and grease but I use it for that and restaruant cooking grease. That is a truly messy job when it comes time to clean the system, like rolling around in the grease. Oh and it STINKS.
