The battery quickly in the charging station and after about 30 - 40 min. he is ready for use again. The nipple is the Hammer, he may be small but it large in his work. I am very ill and therefore had to look for a small and lightweight vacuum cleaner. Since I already since years DYSON use came and seems to me nothing else in the household. Even my assistants were amazed at the power in such a small vacuum cleaner, it's only a matter of time before they also define such a device. The only downside of the nipple is the fast depletion of the battery. But if like me you use the www, you can conveniently purchase a battery and still save it.
