Can anyone recomend a good hard floor cleaner?

I think I really would like to get one but I don't know whether to get the bissel flip it, the hoover floor mate or the dirt devil floor keeper. Consumer reports hasn't done a study yet. Please either point me in the direction or a review of them or if you have one: let me know what you think of it, what you like/dis like, how long you have had it, ease of use, if it is durable and has lasted, etc. THANKS!!!!
