I had an old Dirt Devil model for a few years and even bought a refurbished one because I liked it so much. However, this new one has an on/off switch that is difficult to control. It's smooth and slippery. Sometimes you have to use your fingernail to move it. The clip-on nozzle is also difficult to use. The charging plug has round and square plugs, which are also difficult to connect. In this case, I would have liked it more if Dirt Devil hadn't made so many "improvements" on this vacuum cleaner. The old model was much better!
