HANDHELD VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2018/036123
Kind Code:
A1
Abstract:
A handheld vacuum cleaner (10), includes a main body (22), a motor assembly (114) positioned within the main body, and a dirty air inlet (14) positioned at a front of the handheld vacuum cleaner and extending along an inlet axis (46). The handheld vacuum cleaner also includes a cyclonic chamber (30) in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis (34). The inlet axis and the separator axis intersect to form an acute angle (214) extending between the dirty air inlet and the cyclonic chamber. The acute angle is within the range of 20 to 60 degrees such that when the handheld vacuum cleaner is operated in a normal operating condition with the dirty air inlet pointed downwardly the separator axis is oriented vertically.
