Here it is in a nutshell - most of the extractor/steamer machines on the market are terrible.
They usually don't perform all that well and then last only a year or two before you have to throw them out.

This unit not only works well, but it lasts and lasts and most of the common parts are readily available. We have been selling this machine for many years and rarely have seen any problems.

Dirty water never has a chance to soak into your carpet with this steamer unit means drier, cleaner results. This is because this machine has two suction nozzles.
