1. A handheld vacuum cleaner, comprising:
a body having an air inlet defined at least in part by an air inlet conduit having a first end and a second end, an air outlet, and a handle adapted to be gripped by a user to define a hand-carriable body;
a motor/fan assembly carried by the body upstream of the air outlet and in fluid communication with the air inlet and adapted for generating a working airstream;
a debris removal assembly carried by the body; and
a working air path through the body from the air inlet to the air outlet and including the motor/fan assembly and the debris removal assembly;
wherein the debris removal assembly comprises:
at least one wall defining a chamber having a first dimension extending in a longitudinal direction of the chamber and a second dimension extending in a lateral direction of the chamber, the first dimension being larger than the second dimension, the air inlet conduit extending radially from the at least one wall and wherein the working airstream enters the chamber via the air inlet conduit at the second end;
a debris separator provided in the chamber and adapted for separating contaminants from the working airstream, the debris separator comprising a filter having a screen; and
an air deflector positioned within the chamber, the air deflector in opposition to the first end of the air inlet conduit, the air deflector comprising a deflector wall shaped to direct the working airstream in the chamber past at least a portion of the filter upstream of being provided to the screen;
wherein the chamber defines a central longitudinal axis aligned with the first dimension of the chamber, the air inlet conduit extends along an inlet axis that is generally perpendicular to the central longitudinal axis.
