The argument to remove   is a filter document  so passing in an empty document means  remove all    db user remove       However  if you definitely want to remove everything you might be better off dropping the collection  Though that probably depends on whether you have user defined indexes on the collection i e  whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove   call vs the drop   call   More details in the docs
