best floor steam cleaner?

I don't have any experience with the Shark steamer yet, but I have used the Oreck Steam-It as well as a host of other general household steam cleaning machines that have a floor attachments with them.

A household steam cleaner will be more versatile than a steam mop, and IMHO easier to use. You can get a decent basic steamer such as the SteamFast 275 for about $100, which is less than the Shark Vac-Then-Steam or the Shark Steam Pocket Mop. SteamFast has other models of household steamers as well as stick steamers.

If you have tile and grout, a household steamer will get that grout looking new again, quickly and easily, whereas a stick steamer won't.

no longer devoid of ruining your mattress, steam can injury fabric and reason mould. A vacuum purifier for customary cleansing and if and whilst mandatory an upholstery spot purifier for any stains is you want.

No experience, but the commercials sure does make it look good.
