Boss Pat Fenlon has come in for criticism from the Easter Road club's supporters after his team started the season with four straight defeats - including a 7-0 loss to Malmo in the Europa League and last week's Edinburgh derby defeat to Hearts.
But Saturday's 1-1 draw with the Arabs provided Hibs with their first point of the Scottish Premiership campaign.
United's Scotland Under-21 captain Stuart Armstrong had the visitors ahead after 29 minutes when he slotted under Radoslaw Cierzniak.
And things looked to be going from bad to worse for Hibs when former Scotland midfielder Kevin Thomson was shown a straight red card alongside United's Gavin Gunning after the pair became embroiled in an off-the-ball scuffle.
But the sendings-off brought out the home team's fighting spirit and they levelled with Robertson's powerful drive nine minutes from time.
Now Robertson hopes the draw can be a launch pad to better results.
"We need to get a win," he admitted. "We don't know where it is coming from. We were hoping it was going to be against United.
"But the result is better than we got last week and the week before. It's a point. It's not as a good as we wanted but it's a start."
