It works perfectly, and I have the instruction manual. It's lightweight and easy to use. You can easily clean between narrow furniture and high places by simply stepping on the pedal of the floor nozzle to switch to the sub-nozzle state. It also has a "house dust detection" lamp, and the stopper for upright storage and hose hanger are convenient. Although it's not a genuine paper pack, I've included one, so you can use it right away.
