A four-direction carpet shampooer is disclosed. Example embodiments include: a first brush configured to rotate on a first axis; a second brush configured to rotate on a second axis, the second axis being different from the first axis; a direction of travel sensor to detect the shampooer direction of travel; and a rotation changing actuator configured to reverse the rotation of the first brush on the first axis and to reverse the rotation of the second brush on the second axis when the direction of travel sensor indicates the shampooer direction of travel has changed. Example embodiments also include a shampooer cleaning station comprising: a first brush configured to rotate on a first axis; a second brush configured to rotate on a second axis, the second axis being different from the first axis; and a hair grinding system including protrusions configured to remove hair from a brush roll of a carpet shampooer, and a grinder to grind up the hair and dispose the ground-up hair into a waste water reservoir.
