I bought the 1940 steam mop for my beachfront condo, and it worked perfectly for a year. Even with my seven grandchildren tracking salt and sand onto the tile floors, the tile and grout look as clean as the day they were new. On the high traffic areas I pretreat with ammonia and water in a spray bottle. It takes six to eight pads to clean 1100 sq feet, and the floors are magnificent. The secret is to go slowly so the steam gets into the grout, and change the pads frequently! Then throw them into the washing machine and you're ready for the next time.
The mop stopped working after one year, the electrical connection failed, but I called Bissell customer service and in 10 days had a brand new unit. Thank you, Bissell!
I have had a few Shark mops before this, and they don't begin to compare...the grout doesn't get clean, and it strips the finish off wood floors. Bissell is the way to go!
I'm a happy Nana!
