I've had this mop for 5 years. I was impressed from day one with the quality of the product, and still remain impressed. After five years, I truly believe that this item will last my lifetime. I use it on wood and tiled floors, and only use distilled water. I vaguely recall this recommendation. Prior to using this item, I use my Bissell FeatherWeight Bagless. Another smart item, which I've had for 10(?) years. Its the old 'electric broom' that I grew up with. I remember having a really hard time finding a simple 'electric broom', when I located this item. It was a floor sample, the only one left, and I snagged it. The Bissell SteamMop is tied with the SpotBot Pet (which I recently purchased) for my favorite cleaning tool. Love it, love it, love it. No complaints about this product... except... my darn cat recently took off with the black cap that secures the tube in the reservoir (my own fault... I knew she would grab it if I left it loose). Of course, I can't find it! Can I just buy a cap? Thank you, Bissell.
