I think the air that you noticed escaping from the carrying handle on your Legacy is the exhaust air. When I had my Epic 6500 I noticed the same thing. I have an Epic 6000 now but I dont use it very often so I havent noticed if it does the same thing. I check it out tomorrow night and report my finds. The Lux is not "sealed" the way a Miele is so I think the strong force from the exhaust beneath the on board tools, is also forced under control panel and into the carrying handle.
My vote for a brand new vac is for Miele. Electrolux is the vacuum that started my love of vacuums, probably around age 2, and I still love them. However, if you are trying to be a savy shopper and get the greatest bang for your buck, I think the Miele is the way to go. They are quiet, filter well, have a variable speed motor, wonderful bags, and the SEB236 power nozzle is absolutely awesome!! I traded my 6500 and Renaissance in for a brand new Red Velvet and later added a Blue Moon because I was so please with their preformance compared to the Luxes I had been using for years. I dont think you will be disappointed with the Miele, especially if you already have a Kirby and appreciate a well made deep cleaning vac.
