I love this machine! I live in a home built in 1924, with the original hardwood floors, which have not been properly cleaned by a number of former tenants, over the years, with deep stains, discoloration, and layers of dirt embedded within the wood grain.
After using this floor cleaner only twice, with amazing results! The wood looks less dull, the stains and  grime less noticeable, and with continued use, will erase the dingy, deep staining as the remarkable results after only 2 uses, has clearly proven.
This is my 3rd Hoover Floormate model, and have been pleased with all the results from every model.
I prefer the lighter weight of this newer model, but highly recommend any of the models! Well worth the price!
