I got the cordless Shark HydroVac because I wanted a more convient way to clean the non carpeted floors in my house. After using the Shark HyroVac I was very impressed how well it worked.  The HydroVac is  easy to use and put together after reading the directions frist, it is light weight, very simple to maneuver back and forth, does not leave a film on my floors and come with its own charging station. I love Shark products and will continue to purchase them.
