Embodiment Construction

[0022] figure 1 with 2 A hand-held vacuum cleaner 2 is shown comprising a main body 4 having an elongated handle 6; a cyclonic unit 8 having a longitudinal axis X; and a cleaning implement 10 in the form of a nozzle secured to the cyclonic unit 8. . The cyclonic separation unit 8 extends away from the handle 6 such that the cleaning implement 10 is at the end of the cyclonic separation unit 8 furthest from the handle 6 . The cleaning tool 10 extends away from the cyclonic separation unit 8 along the longitudinal axis X of the cyclonic separation unit 8 .

[0023] The main body 4 also includes a suction generator 11 comprising a motor 12 and an impeller 13 positioned above the handle 6 and near the rear of the handle; and an accumulator 14 positioned directly below the handle. An actuator 16 in the form of a finger operated trigger is provided at the upper part of the handle. A trigger guard 17 extends forwardly from the handle below the trigger 16 . The handle 16 is arran...

Abstract

A handheld vacuum cleaner (2) comprising a handle (6) by which the vacuum cleaner is supported during use, a cyclonic separating unit (8) comprising a separator (18) having a cyclone chamber (28) which defines a separator axis X and an inlet duct (30, 36) having an inlet duct axis which is substantially parallel with the separator axis X. The cyclonic separating unit (8) extends at least partly around a portion of the inlet duct (30, 36).

Description

technical field [0001] The present invention relates to a hand-held vacuum cleaner comprising a cyclonic separation unit, and to a stick vacuum cleaner comprising a hand-held vacuum cleaner. Background technique [0002] EP2040597A discloses a handheld vacuum cleaner comprising a cyclone unit extending along the handle. A difficulty with such vacuum cleaners is that the cyclonic separation unit blocks access to narrow gaps, such as those formed between items of furniture or between an appliance and a wall. In order to clean these gaps, cleaning implements such as sticks or specially designed cleaning nozzles have to be used. [0003] GB2484146A discloses a stick vacuum cleaner, including a hand-held vacuum cleaner, similar to the vacuum cleaner disclosed in EP2040597A. Stick vacuum cleaners are formed by attaching a stick to the vacuum cleaner, and attaching cleaning heads to opposite ends of the stick. Such stick vacuum cleaners are increasingly being used as an alternat...
