I'm looking for a word that means "doing lots of work but in vain"
the amount of work done is a lot, but the results obtained is very small.

A phrase you could use is "Sisyphean task/job/cycle", or simply "Sisyphean" as an adjective.
In Greek mythology, Sisyphus was punished for his self-aggrandizing craftiness and deceitfulness by being forced to roll an immense boulder up a hill only for it to roll down when they near the top, repeating this action for eternity. [source]
Therefore, you could say:
You are trying to accomplish a Sisyphean job.
or
Can you help me with the Sisyphean task of cleaning this dirty bathroom?
