HANDHELD VACUUM CLEANER

A handheld vacuum cleaner includes a fluid flow path extending from a dirty air inlet to a clean air outlet, a main body including a handle, and a fluid flow motor positioned in the fluid flow path. The vacuum cleaner further includes a dirt collection region with an openable bottom and a cyclonic separator in the fluid flow path. The cyclonic separator includes a cyclone chamber having a first end wall and a second end wall, a cyclone dirty fluid inlet, and a cyclone clean fluid outlet. The vacuum cleaner further includes a filter chamber in the fluid flow path downstream from the cyclonic separator and upstream from the fluid flow motor. The filter chamber includes an outlet fluidly communicating the filter chamber and the fluid flow motor and a tangential inlet fluidly communicating thecyclonic separator and the filter chamber. 种手持式真空清洁器，包括：从脏空气入口延伸到清洁空气出口的流体流动路径；包括手柄的主体；位于流体流动路径中的流体流动马达。真空清洁器还包括具有在流体流动路径中的可打开的底部的污物收集区域，以及旋风分离器。所述旋风分离器包括：具有第端壁和第二端壁的旋风室，旋风污物流体入口以及旋风清洁流体出口。真空清洁器还包括位于流体流动路径中旋风分离器下游和流体流动马达上游的过
