If it won't work without a ground wire, but still works with one, then you must have a ground/earth connection to make it work - it sounds like there is a safety device that needs an earth to release, you could almost certainly bypass this relatively easily, but it will be there for a good reason and that would be dangerous. Bearing this in mind, regardless of which 2/3 prong adaptors you use, without an earth connection it will not function without risk probably of electric shock from the case or damage to the vacuum, else the safety device would not be there. Get an electrician to your home, and make him install grounded sockets where necessary (should be all, but at least get a couple). Ungrounded/unearthed domestic power sockets at all domestic AC voltages are lethal eventually, to man or machines. A lot of devices don't need an earth, but especially something with a big motor or a metal case usually does. At least ask a local electrician what he thinks. If you want to do it yourself, an Earth circuit in your home is not too hard to achieve if you have basic wiring skills (and access to the ground floor), but most insurance would dislike the idea - if you want to - post again and I may talk you through it. Hope this helps :) Please be careful :(

These motors have a fuse incorporated in the field winding and it sounds like that blew. These motors sometimes overheat at the front bearing and the bearing will melt into the plastic housing. This will cause the fuse to blow. It sounds like that's your problem. You can remove the motor by removing the three screws on the bottom of the powerhead and then check the front bearing for any bubbling or blistering in the plastic housing. The shaft of the motor should turn easily.
