Chesterfield who had only scored 8 league goals who season before the start of the game scored their first goal after 11 minutes after a Cade shot had been saved by Rhys Evans only for Robinson to score from close range seconds later.
Robinson made it 2-0 to the home side on 19 minutes when he was able to beat the advancing Evans to score again from close range.
Andy King then took Viveash off from the Swindon defence to replace him with the French man Ruster after only 25 minutes. Viveash didn't shake Ruster's hand, but instead went straight down the tunnel without even stopping at the bench.
Chesterfield made it 3-0 on 71 minutes when Cade who came close to scoring earlier on was allowed to score from close range.
Tommy Mooney came close for Swindon late on making the Chesterfield keeper make a good save.
New loan signing Deon Burton also came close to scoring but couldn't hit the back of the net.
This was Swindon's first game of the season where they didn't manage to score, it was also Chesterfield's first win of the season.
Overall a very poor game, but Chesterfield who only had about 5 chances to score all game took 3 of them to give them the win. Swindon now travel north again on Tuesday to play Tranmere Rovers who are also near the bottom of the table.
Swindon have now dropped down to 12th in the table.
