What the technology is
When it was invented
What it is used for
And explain how you feel about it
This piece of technology that I really like using is Dyson vacuum cleaner, an electric appliance. I don't know exactly when it was invented, to be honest. Regular vacuum cleaners may have been around for many decades, but it seems like the Dyson ones have only been in the market for a couple of years. Unlike the ordinary vacuum cleaners, which are very clumsy, this product looks kind of like a machine gun. It's portable and handy. It can not only be used for cleaning the floor, but also for sanitizing pillows, sofa cushions and things like that. It's very easy to use. I only have to point the head of it to the place or things that need to be cleaned and then pull the trigger, just like firing a gun and the dirt will be sucked into the cleaner easily. I think it's a very useful invention, because it saves a lot of manual and labor work for me. Cleaning the house has now become relaxing or even fun . I'm grateful for this piece of technology.
