This replacement vacuum motor has the power of a freaking jet engine and seems to be much better designed than the OG motor that comes with the older Roomba J7 models. The wires are a bit thicker and the case around the motor housing is designed to keep dust and dirt from getting into the motor components unlike the original. It is a bit louder though due to more power. I had no issues installing this replacement motor, very much a plug and play. 10/10 would recommend as an upgrade/replacement.
