My favorite electonic device

I think electronic devices are weirdly fascinating in a sort of way, but I think my favorite one, even though I almost never use it, it’s the vacuum cleaner. Back in nowadays, people had to use brooms if they wanted their floor to be clean, and they had to sweep until eternity everyday. But now, if you plug in this technologic thing on the wall you can clean all the dirt and dust from the floor in a few seconds. It’s like magic. I think it’s a terrific idea and a little bit surprising. I don’t personally own a vacuum cleaner,  it’s my family’s and I don’t really use it that much, so actually I don’t know how we got it, which brand is it, or if we have ever lost it. All I know is that it is great.
