I bought it because it was compatible with the old Takanori EARTH MAN who was retiring in the workplace. Because it can purchase one by one, it is safe because it can be purchased even if it breaks at the site.
It puts power and puts the vacuum cleaner on, so the tip of the extension pipe is "cracky" easily. Although it was fixed with a gum tape, I was staggering my power, but since there was an extension pipe, I replaced the cracked one. I did not know that such things would come in my hands, so I thought that the vacuum cleaner was old and thrown away, but if you do maintenance, you can use it again. I'm glad. There are a few extras as well so that they can break.
