However, I will say it once more because it bears repeating: this is a broom, not a vacuum cleaner; thus, you should not part with an old and loyal friend because of this. In general, of course, the idea is really nice; the construction quality and materials are at the best level. This one is only effective for cleaning the surface. And it makes no difference whether model you get, whether you get the cheapest one for 20 yen or the most expensive one for 50 yen; the outcome is the same since it is checked. By the way, a single charge at the medium power setting is sufficient for three to four days' worth of cleaning for a regular kopeck piece.
