The answer to this riddle is "a staircase". Of course the staircase does not actually move up and down, but when you refer to a staircase directionally, you are either going "up the stairs" or "down the stairs". Its function in and of itself is to "go" up and down.

Yes, hover can mean to float or remain suspended in the air without moving in any direction. It can also refer to staying in one place while moving slightly up and down or side to side without touching the ground.
An object moving at a constant speed means it is covering equal distances in equal intervals of time without changing its velocity. It maintains a consistent rate of motion without speeding up or slowing down.
An escalator is a moving staircase that transport people vertically between floors without requiring them to walk, while a lift (elevator) is a compartment or platform that moves vertically within a shaft to transport people and goods between different floors of a building. Essentially, an escalator moves people continuously, while a lift moves intermittently between floors.
