Pros and Cons on the cordless Shark HYDROVAC MESSMASTER 3 IN 1 VACUUM, MOP. Pros are manny, self-cleaning, separation of clean and dirty water, cordless, powerful suction, wet dry vacuum stain boost mode, easy to use, and much more. cons or should I say Con and I can only find one, and that's the battery ,but to be fair, I have a large home that I clean. So I found it useful, easy to use, I just grab it, and it's ready to go since it has a self-cleaning charger I love it.....
