I don't have this steam mop, I have a canister steamer. At $179, the Oreck is more expensive than the Shark and Haan steam mops, but it has certain advantages.

It has a 1 liter tank, which is roughly 3 times larger than the Haan 11 oz. tank. The Shark may have an even smaller tank - I'm not sure.

The Oreck has alligator clips on the top of the mop head, which means that you don't have to invest in proprietary cleaning cloths. This is a huge advantage; you could use cut up sections of towels or buy a package of microfiber cloths in the auto section of Walmart and steam all day with the Oreck.

The Oreck seems more versatile; you can use it without the mop head.

What the Oreck and all the other steam mops lack is high temperature steam. They heat to 212 degrees. The good Italian canister steamers, which cost hundreds of dollars more, heat to over 300 degrees. All steamers lose heat between the tank and where the steam comes out. The expensive canister models lose some 30 degrees, with the steam at the cleaning tip around 260-270 degrees. The steam mops don't tell you what the temperature at the tip is.

THANK YOU, for your clear information! A canister seems to have more options for varied cleaning.
