I like this vacuum a lot. The "turbo" brush head works better than I expected. The "turbo" brush does make a high pitched sound otherwise the vacuum is fairly quiet. More than enough suction, sometimes I bleed off the suction a bit because otherwise it inhales small rugs. For a single guy with no dogs there's no need to spend more. Before the C1 Turbo I had an Electrolux from the 70's which was better but the Miele is much much lighter. Not looking back. If you have big dogs get a bigger machine such as the upright model which has big bags and an electric beater.
After using for several months, I would add that I wish the power cord was longer than 18 ft. Also, the tool holder falls off. Plan on leaving it in the closet. I still would not spend more.
