A vacuum cleaner head 10 for cleaning carpet comprises a head portion 15 which is tiltably attached to a body portion 12, the head portion 15 having a transversely extending suction mouth 18 on its underside 17. An elongate depending blade 21 extends longitudinally of the suction mouth 18 at a position between front and rear working edges 27, 28 thereof. The suction mouth 18 comprises front and rear working edges 27, 28. An arm 14 tilts the head portion 15 such that the suction mouth 18 faces rearwardly when the head 10 is moved forwardly across a floor surface to lower the front edge 27 of the mouth 18 into engagement with the carpet C. The front edge 27 distorts and parts the carpet fibres F to allow trapped dust to be extracted. Dust is also dislodged as the carpet fibres suddenly recover their shape. This process is repeated by the action of the blade 21 and dust extraction from the carpet is greatly improved and a comparatively low power motor can be used to induce the airflow through the cleaner. |
