No, cleaning a vacuum cleaner does not transform you into the vacuum cleaner. Cleaning the vacuum cleaner is simply an act of maintaining and tidying the device to keep it in good working condition. It involves removing dust, debris, and any other particles that may have accumulated inside the vacuum cleaner during use.
The statement you mentioned seems to be a playful or humorous way of suggesting that if you clean the vacuum cleaner thoroughly, you become intimately familiar with its internal components and workings. However, it's important to note that the act of cleaning an object does not cause any physical or metaphysical transformation of a person into that object. It's just a regular cleaning task, much like cleaning any other household appliance or tool.
