Definitely Panasonic. We've gone through terrible headaches with every other company, and they are either ugly, or way to heavy, or don't clean good, or worst, die in less than a year! Panasonic is the only vacuum that lasts us for years and years with no problem. Its excellent, and after going through nightmares with all other vacuums, I consider Panasonic the best vacuum out there. Its just perfect, in looks, in performance, in weight, and in its features.
