I have been a Shark customer for years and have had other Robot cleaners that truly disappointed me.  This 2 in 1 Self empty robot has made my life so much easier!! It is quiet, cleans even in corners and around table and char legs! I own 3 large German Shepherd Dogs that shed year round and keeping the floors clean was a chore.  We also have engineered hardwood floors and I have never been able to make them look clean with traditional mopping.  This Shark has solved all my floor cleaning issues and I HIGHLY recommend this to anyone who wants their floors clean without having to do it yourself!
