Those are different, though. Your statement leaves ambiguity as to who will tend to the objects' needs. Sometimes the implication that you are the one expected to do it is clear, but far from always.
People on the spectrum will probably struggle with that type of ambiguity too, which is worth keeping in mind.
Better to say that it is the thing that has 'needs' - e.g. 'the rubbish needs to be taken out [before the dustbin people get here]'
