This is a set of iRobot Roomba and Braava. The Roomba was purchased several years ago. It sometimes has issues and takes a while to charge, but it still works. Please see the photos for the damage on the underside. It functions without problems and cleans well. The Braava's terminals are rusty, so it only works occasionally. However, the battery is new, having been purchased a few months ago. This is recommended for those who want the battery or need parts. Many Braava accessories are also included. Please understand that these items are as-is before purchasing.
