I like the vacuum and the spray cleaning.  However, the liquid cleaner leaves my oak floors streaked and filmy.  After I use it, I have to buff my floors.  This takes more work than when I was getting down on my hands and knees to clean the floor!  I called Customer Service and they told me I had to use the VacMop cleaner only -- I couldn't use my own liquid 
cleaners in the VacMop.  Please improve the liquid wood floor cleaner.  It's ruining my oak floors and I had to stop using my VacMop.
