Coventry extended their unbeaten home run to seven games by beating Swindon 3-1.
Swindon have been a force to be reckoned with away from home all season, but a Marc McNulty double and a goal from Maxime Biamou ended the Robins' three-match winning run.
Ollie Banks' 39th-minute goal was nothing but a mere consolation for David Flitcroft's outfit.
Biamou opened the scoring with a great finish as he lashed the ball into the top corner after 17 minutes.
Five minutes later it was 2-0 after Matt Preston hauled down McNulty. And it was McNulty who duly stepped up to beat Reice Charles-Cook from the penalty spot.
Banks, playing in only his second game for the club, then pulled one back for the visitors.
Banks met Ellis Iandolo's sublime cross and kept his composure to slot home.
But McNulty put the game to bed with his 13th goal of the season with nine minutes left as he fired into the bottom corner from the edge of the box.
