Outstanding robot, I'm so so impressed with how quickly the J9+ Self emptying Robot Vacuum was able to map my hole house. The robot is a peace of art, so beautiful and modern design and what I like the most in it was that it makes almost no noise. That makes my heart very happy! Cleans all rooms very well and the fact that you don't need to clean it all the time that you use is amazing! I TOTALLY RECOMMEND THE J9+ Self emptying Robot Vacuum!!!! ♥️
