I have 3 little dogs that I adopted from abusive conditions. They weren't housebroken at the time I took them in. While they are all making great progress, there are still the occasional "accidents". It's important to sanitize the floors and remove any scent so that my dogs will be discouraged from using the areas again. I had been using another appliance which required using chemicals that I didn't realize contained ammonia. Urine contains ammonia. I learned from an animal behavior specialist to NEVER use ammonia products to clean floors in homes where dogs live. My entire house is porcelain tile, the ammonia scent was in all of the grout. You can imagine how confusing that was for my dogs. (wasn't fun for me, either)
This steam mop is lightweight, easy to use, and a great value.It stands upright on it's own, heats quickly, & gets hot enough to kill most bacteria, (& smells) & cleans without the use of expensive chemicals. The reusable pads wash easily. It also has a removable tank that holds enough water so it doesn't have to be refilled so often as to being annoying.
I think the only con would be a small, easily changed, design flaw. The tank has to be turned upside down to fill and because of it's shape, it doesn't sit flat. I have to prop it in my dish drainer, so I can use both hands to hold a gallon jug of distilled water to fill it.
Over all, I'm very pleased & would recommend the Bissell PowerFresh Steam Mop Hard Floor Cleaner 1940 to anyone.
