I have one of the original ones, which I use for my kitchen. It's OK. I never purchased refill cleaning solution, preferring to use a mixture of white vinegar and water. If I need stronger cleaning solution, I have a spray bottle that has a detergent solution which I spray on the floor as I'm mopping. I didn't especially care for the swiffer brand cleaning solution - it seemed to leave a residue behind. Also, instead of their disposable pads, I use a microfiber cloth, which I can wash and I purchased from Sam's in a big bundle for ~10. The original wet jet had 4 little rubber openings on the top of the "business end" which was the method for fastening a cleaning pad. I think the newer ones have a velcro type bottom to attach the pads to. I don't know if the microfiber cloths would work with the newer ones. Sooo that's a long story but for me, the bottom line is it's very convenient and quick since I don't use the branded consumables.
Jabbur, I also have a Floormate. It's a very good machine and cleans well and I use it for heavy floor cleaning. It's less convenient that a wet jet because you have a fairly small cup for the dirty water and a fairly large cup for the cleaning solution. There is also a filter. You must clean the dirty water chamber and the filter pretty much every time. Also, if you are cleaning a large area, you will have to stop and empty the cup and refill the solution several times. That said, the scrubbing brushes work very well and it really does vacuum up the water well - the floor is almost dry immediately after cleaning. My mother and daughter both have one because they can use it on their Pergo-type floors since it sucks up all the cleaning water so effectively. But it isn't quite as quick and trouble-free to use as their marketing might imply.
