Stockport collected a Football League record by notching up their ninth straight victory without conceding a goal at 10-man Swindon's expense.
The home side opened the scoring after when Anthony Elding converted Adam Proudlock's cross from close range.
Elding grabbed his second of the game when he turned in the box before firing the ball home from 15 yards.
Swindon's Jerel Ifil was sent off for a second booking before Liam Dickinson wrapped things up with a great finish.
