Eoin Doyle took his tally for the season to 25 with a brace to keep Swindon top of the Sky Bet League Two table after a 2-0 win over Scunthorpe at the County Ground.
The Robins were sluggish after not playing for 10 days due to postponements but still had too much quality for their lowly opponents.
The hosts took the lead on 41 minutes thanks to Doyle's close-range header from Diallang Jaiyesimi's cross.
As Scunthorpe opened up in an attempt to equalise, they left space in behind and Swindon made it 2-0 it in the 77th minute when Doyle latched onto Michael Doughty's pinpoint throughball and dinked his shot over goalkeeper Rory Watson.
Home goalkeeper Steven Benda had a quiet night but did save a half-volley from John McAtee, while Paul Caddis struck the bar with a free-kick in the first half for Swindon.
Doyle could have had a hat-trick but spurned an effort from within the six-yard box from Doughty's low ball in from the left.
