Just bought a house with floating wood floors. The floors are pretty dark and I am having trouble mopping them and them looking clean. What's the best product on the market for mopping wood floors? I tried sweeping with a Swiffer Sweeper (but would rather drag out my Rainbow with the brush attachment or just a regular broom) I tried mopping with a sponge mop and spraying some cleaner that came from the store where the flooring was purchased, but it just leaves streaks from my mop. Nothing I try leaves the floors shiny and clean-looking.

Any advice?
