If you are not making very much money to begin with OP, then this family has zero right asking you to do house chores while caring for their child.
Sounds like they need a Nanny/Maid, but only are willing to pay peanuts in return.
Normal Nanny duties include washing only the dishes used during your shift, picking up any toys played with while you were there and wiping up any messes the kids make.
If the spill crumbs on the floor then yes you should sweep them up.
If they spill something sticky, it is your responsibility to mop up.
However for the family to expect this to be done for their own messes....Well they must have a screw loose somewhere because you are not responsible for taking out their garbage or vacuuming their rugs.
It is the family's responsibility to make sure the trash is taken out beforehand.
Remember everyone that OP is being underpaid here.
