Hoover gave me this product to try on my hardwood floors. It was very easy to assemble and I was able to begin using it right away. I have engineered hardwood flooring. It worked great cleaning my floors and did not leave any type of residue. I also used it on my ceramic tile in my bathrooms. I was very happy with the way it performed on the tile as well. Once again, it did not leave any type of residue. I love the feature of having a dry vacuum and wet floor cleaner in one product. The self-cleaning option is a great addition and clean up was very simple. I highly recommend using this wet/dry vacuum!
