Teenage striker Ashley Vincent netted a brace - his first goals for Cheltenham - as the Robins thrashed Dagenham.
Vincent put the hosts ahead early on with a fine solo effort and then doubled the lead after the break by tapping in from close range.
John Finnigan hit the bar before Chris Moore got one back for the Daggers with their first attack of the contest.
But Grant McCann scored a penalty after a foul on Steve Guinan and Finnigan and Damian Spencer made it 5-1 late on.
