1. A vacuum cleaner comprising:
- a housing adapted for movement over a surface to be cleaned and having a suction nozzle and an agitator chamber defining an agitator chamber height;
a sole plate provided on a bottom of the housing and defining a suction nozzle inlet of the suction nozzle;
an agitator provided in the agitator chamber 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 with the suction source; and
a suction channel forming a portion of the working air path and at least partially defined within the base housing by the sole plate, the suction channel comprising;
a channel inlet fluidly connected to a suction nozzle inlet and; and
a channel outlet fluidly connected to a downstream suction source;
wherein the channel inlet spans the width of the agitator chamber and defines a channel inlet height that is less than the agitator chamber height.
