A drive system for a floor cleaner, comprising: a motor (50, fig. 3); a cooling fan 41; a diffuser 42 comprising a plurality of vanes 42a arranged around a circumference of the diffuser, wherein the length of the vanes is non-uniform; and a longitudinally extending drive housing (22, fig. 3). The motor and the cooling fan are longitudinally disposed with respect to one another within the drive housing, and a drive output of the motor is configured to drive the cooling fan. The length of each vane may be different to the length of the vanes located adjacent to said vane around the circumference of the diffuser. The centre of rotation of the cooling fan may be offset from a central axis of the diffuser. An agitation member may be coupled to the motor where the motor causes the agitation member to rotate about the drive assembly.
