Review on iRobot Roomba s9+ (s955020) Robot Vacuum Bundle: Wi-Fi Connected, Smart Mapping, Ideal for Pet Hair, with Automatic Dirt Disposal, Bonus Accessories by Katie Evans

Great idea but had to return. That would not work on our relatively thick and dense carpet. This is not a pile at all, but a dense and thick polyester rug. The wheels hiss and skid as they try to move. Forward was better than reverse when the wheels kept spinning and he couldn't reverse if he got stuck. Because the wheel was spinning, the map got messed up because I had to help her peel it off, confusing her position. It's sad to see this. It would help their products if the software would allow you to direct them to where you want them when they can't find that area on their own.
