I previously owned 2 Shark Steam Mops. They seem to wear out after about 6mos. I decided to give the Bissell 3n1 a try. I like the Bissell, but it doesn't seem to do as good a job on our hardwood floors as the Shark. It takes longer for the floors to dry with the Bissell than the Shark, which seems to almost dry instantly. Also, the Shark comes with different sized attachments and has a much longer cord than the Bissell 3n1. Although, I like my purchase of the Bissell, because it does clean the floors, I think the Shark is a better Steam Mop. One other note, of which I found out the hard way. If your home has hard water and you want your steam mop to last, be sure and use distilled water.
