It is the best carpet cleaner I know. I have used it for many years. It comes with everything you need, you just have to buy the cleaning fluid from HAGERTY. I have 4 doggies and need it almost daily....

Everything you need is included. Suction hose with integrated water hose, plug connection, small suction nozzle (for mattresses, sofas or car seats), floor nozzle for carpets and connecting tube.
By the way, very good suction power - I am very satisfied. The only disadvantage is that all units are a bit noisy.

Everything as shown included
