I have 2 self propelled Vacuums they all work but only one of them the power drive works.The one that is broke I have the parts and I tried to fix it but couldnt.The motor and everything runs great.The one that works is in great shape its differnt though the Esp button is on the Vacuum unlike the other.The Power Drive works perfect on it and is a great Vacuum.I am going to list them on Ebay but was wondering how do I go about shipping it?I am worried if I break the handle down it will screw it up.Or should I just put it in a big Box the whole thing?Any Advice?
