Abstract
Pivoting brush heads and associated machines in which cleaning of interior tube surfaces occurs by a forward non-cleaning pass of a pivoting brush head through a tube followed by a reverse cleaning pass where the pivoting brush head engages and cleans the interior surface. The pivoting brush head has a first position for the forward pass producing minimum engagement of interior tube surfaces, and a second position for the reverse pass of full cleaning engagement with the interior tube surfaces.
