Surely it should be my mom and not just mom, there needs to be an article befor the work mom
So "posprzątać" is supposed to be the perfective of sprzątać, right? Because in internet I also found that "sprzątnać" is the perfect of "sprzątać". Is there a difference between the two perfective forms? Or is it just the same meaning and same usage?
I think both could work here, but 'sprzątnąć' can be also used to refer to some object which has to be put in its right place.
