    Abstract: A surface cleaning apparatus comprising a cleaning head and a brushroll. The cleaning head includes a cleaning head body having an agitator chamber including an opening on an underside of the cleaning head body. The brushroll is rotatably mounted to the cleaning head body such that a portion of the brushroll extends below the underside for directing debris into the opening. The brushroll includes an elongated body extending laterally between a first and second end region, a slit opening extending between the first and second end region, angular stationary teeth extending proximate to an edge of the slit opening, and a cutting blade configured to be at least partially received within the slit opening and to move laterally between the first and second end regions. The cutting blade bar includes teeth that are configured to engage with the stationary teeth to cut hair.
