Question

why Jupiter is called vacuum cleaner ​

Answer 1

Answer:

Jupiter is called the vacuum cleaner of our solar system because Jupiter is the most massive planet in the system and it's gravity has sucked in a lot of comet asteroids and meteors that might have gone in closer to the sun and struck Earth.

Answer 2

When a Jupiter-like planet's orbit is a bit more eccentric than ours is, gradually the gas giant's orbit starts to bend towards its star. On its way, the planet rips apart any material that would have otherwise eventually formed into a planet like Earth.
