There was so many models to chose from, I researched them all & this was the one that best fit our needs. I don't like to use a lot of chemical products between having babies & animals in my house. I love that this only uses a small amount of cleaner & gets the job done! The days of vacuuming, mopping, scrubbing & steam cleaning my floors are over! This picks up everything from my dogs fine fur, to rice to even crayon on the floor! It self cleans which is great because who has time to clean their mop heads all the time. My floors have never looked so clean & it takes me a quarter of the time is use to. Highly recommend for hardwood
