Speaking to BBC Scotland after the 35-22 win, man-of-the-match Peter Horne said: "We were disappointed last week, we created a few chances and didn't take them.
"Tonight we had that clinical edge to us, converted a few into scores having got on the end of a few line breaks.
"Everyone is a bit bi-polar. After last week we're the worst team in the competition.
"It's nice to show we've still got a bit about us, we can score tries and nobody will fancy coming here.
"We've got two games (against Ulster and Edinburgh) to get the momentum going again and we can look forward to that home semi with our fans behind us."
That Scotstoun semi-final could be against Scarlets - a prospect head coach Dave Rennie says the Warriors would welcome.
"It would be fantastic to come back here with the likelihood of playing someone like Scarlets," Rennie said.
"We were poor against them and we'd be rapt to get the opportunity to right the wrong."
