My wife and I have spent thousands and thousands of dollars here but NO MORE! Sent back my return they did not accept it said "heavily used" it was a Vaccum robot that could not go from hardwood floor over a tiny throw rug. We never used it after the test. I'm sure everyone that bought one returned it. Do not shop here! I will reach out to our media here Channel 8 on your side to get a story regarding the lack of returns and holding customers hostage. Only one Star because it would not let me give zero stars
