Two bumbling robbers tripped over each other moments before mugging a car wash attendant of $800 at gunpoint, according to video footage released by the police.

The clumsy pair –– a man and woman –– approached the attendant booth at Bedford Car Wash at 7 W. Bedford Park Blvd. in the Bronx just after midnight Oct. 2, police said.

On their way, the two robbers trip over one another and go tumbling to the ground, surveillance video shows. After the awkward plunge, the pair continued to the booth, whipped out their guns and hit the 29-year-old worker on the head before fleeing north with the cash on Jerome Avenue, cops added.

The victim was taken to St. Barnabas Hospital, where he was treated for bruising and swelling to the head.
