Spacecraft! I confess that this is not how our family normally cleans the entire apartment, but I stole the vacuum from my wife and did it myself. I was perplexed as to how such a tiny vacuum cleaner with a suction capacity of only 25 watts (!) could be utilized for what it was designed for. For reference, our former standard "Korean" was once 260 watts. It ended up being -! The nozzles appear to be the cause. contains 5 nozzles, 3 of which have motors. Effectively sucking or gathering wool, dust, grits, etc., but they drain batteries. If the work takes 40 minutes without nozzles, it takes 20 to 25 minutes with nozzles. The vacuum itself is excellent, however since it involves the nozzles, I hope that they will actually last longer than the two years covered by the warranty as I haven't seen Dyson sell such nozzles independently. Everything is well distributed throughout, and it fits comfortably in the hand. The friend's son went around our apartment while using this "blaster" to frighten everyone who was visiting. A few days later, when I went to clean the automobile, I alarmed the nearby residents in the elevator. Another benefit is that the blasted air is filtered by a few tiny internal filters that can be washed, making it possible for the young daughter to use the vacuum cleaner without being scared by the noise or the smell of dust. There is a typo here in the description; the battery in a genuine vacuum cleaner is Li-Ion, not Ni-Mh.
