If you are talking about the rubble in the pit at Ground Zero then I would say the Memorial Day weekend of 2002 was the time when everything was cleaned up.
About 9 months.
A better question would be
WHY did Mayor Rudy Giuliani, order the destruction of valuable evidence
by having trucks roll all night the 9/11/2001 do remove rubble from ground zero,
are there any documentary photographs of the rubble pile before it was disturbed by
cleanup crews?
The fires on ground zero burned for 3 months after the towers fell.The site was officially closed on May 30, 2002 when a single steel girder that stayed upright and was written on by all the departments assisting with the number of their dead, was removed.
