Cheltenham suffered their first defeat of the season as they were well beaten by Accrington Stanley.
Stanley took an early lead when Padraig Amond raced clear to slot past Robins goalkeeper Scott Brown.
They doubled their lead just after the half hour through George Miller, who found the bottom corner of the net from just inside the penalty area.
Romuald Boco sealed victory after beating the offside trap to find himself one on one with Brown.
VIEWS FROM THE DRESSING ROOM
Cheltenham Town manager Mark Yates told BBC Radio Gloucestershire:
"We had lots of chances, but if you don't do the basics right and don't work hard doing the right thing which conceding three goals at home is not doing the right thing, you don't get that little bit of luck you deserve when you put it in.
"I'm not one for coming out and naming names, but we were hopeless today.
"They were better than us, I think every punter in the crowd could see they wanted it more.
"We were poor, credit to Accrington they were better than us, we've got a lot of work to do."
