Bye-bye, Banksy.

A Brooklyn family is about half a million dollars richer after selling a mural of a little robot that the iconic graffiti artist Banksy painted on their Coney Island building for 13 years ago.

The Ruoccos decade-long effort to cash in on “The Tagging Robot” ended last month, when an arts company took down an entire section of their Stillwell and Neptune avenues brick wall and shipped it off to a trendy brewery in Connecticut, the family said.

“Brooklyn family strikes gold!” Richard Ruocco, of Bergen Beach, joked to The Post Wednesday.

The Ruoccos had been trying to pawn off the famous mural since they effectively hit the art world lottery, when the enigmatic graffiti legend painted the bot on their building in the middle of the night back in October 2013, shortly after Superstorm Sandy.

The piece, which the family lovingly calls “Mr. Robot,” depicted the android spray painting a barcode, and was one of several barcode murals that Banksy blanketed across the globe that fall.

The Ruoccos initially had no idea that the graffiti was by a famous artist until swarms of gawkers came to witness the viral sensation.

They immediately protected Mr. Robot behind a roll-down gate and hired a security guard — and started looking to make a bundle off the work in the arts market.

“Why not? What are we going to do with it? Leave it on the wall and lose the money,” said Ruocco, who is cousins to the Russo family behind Gargiulo’s in Coney Island.

Unfortunately, the hype around Banksy died down and buyers were hard to come by until Ruocco’s older brother, Anthony, read that a Connecticut beer garden had acquired another Banksy mural that was left in The Bronx during the same era as “Mr. Robot.

Foolproof in Bridgeport last February installed a massive wall showing a young boy spray painting the words “Ghetto 4 Life” on a brick wall while a butler in formal attire stands beside him holding a tray of spray paint cans — which initially caused an unwelcome stir for “insulting the neighborhood,” CT Post reported at the time.

Anthony Ruocco called the brewery over the summer and “brokered the deal” to pass along the Robot mural, Ruocco said.

“We didn’t sell it for what we originally wanted. We lowered our price and he went for it. Not too many people were willing to buy a brick wall,” said Ruocco, adding that the buyer also had to pay about $75,000 for art shippers to remove and transport the mural.

Representatives for Foolproof did not immediately respond to The Post’s request for comment.

An incredible video shows Fine Art Shippers meticulously shoring up a portion of the brick wall into steel framing and jackhammering it out into one piece before shipping it off to Bridgeport, a journey first reported by Coneyologist.

Ruocco did not want to share how much cash the family received for the piece, but teased that it was for “less than half a million bucks.”

“That’s too personal. No one needs to know that, except my accountant,” he said.

He and his five siblings evenly split the sale, which leaves “enough to buy a nice car each.”

“We’re a very fair family. I know that’s what our parents would have wanted us to do. We shared everything right to the penny,” said Ruocco.

One of the siblings has already treated themselves to a cruise and Ruocco dreamed about buying a new car for his collection, though he admitted his wife would make him get rid of one before adding another.

The Ruocco siblings, now all in retirement, are planning to sell the building where the Banksy mural once lived. It had once been the site of Aiello’s catering, which the family ran from the 80s to the 90s.
