Worked great for a while and then stopped fully charging. Now only runs for about two minutes and stops. Checked all contact points, made sure the roller ball was free to move, spent 20 minutes on the online chat being asked to send a picture of the sales receipt AND a picture of the serial number. So have your vacuum handy! Then I was told the vacuum was out of warranty. I knew that when we started chatting. I had plenty of time to read the online reviews and all the negative ones were regarding the battery. So I need a new battery pack which is $80 and I am not sure that is even the problem and that the new battery will last longer. I do not recommend this product.
