A vacuum cleaner comprises a housing adapted for movement over a surface to be cleaned and having a suction nozzle and an agitator chamber 238 defining an agitator chamber height H2, an agitator 38 provided in the agitator chamber 238 adjacent the suction nozzle, a separating and collection assembly for separating and collecting debris, a suction source in fluid communication with the suction nozzle and the separating and collection assembly for generating a working air stream from the suction nozzle to the separating and collection assembly, a working air path fluidly connecting the suction nozzle and agitator chamber 238 with the suction source and a suction channel 230 provided with the base housing and at least partially defining the working air path, the suction channel 230 comprises a channel inlet 288 fluidly connected to a suction nozzle inlet and a channel outlet 252 fluidly connected to a downstream suction source, wherein the channel inlet 288 spans the width of the agitator chamber 238 and defines a channel inlet height H1 that is less than the agitator chamber height H2. A sole plate 228 can define the suction nozzle inlet and at least partially defines the working air path. |
