A suction head comprising: - a head body provided with a lower face which is configured to be directed towards a surface to be cleaned, and with a suction opening leading into the lower face of the head body, - a connecting member which is fluidly connected to the suction opening and which is configured to be mechanically and fluidly connected to a distal end portion (15.1) of a suction tube of a vacuum cleaner, the head body being pivotably mounted relative to the connecting member about a pivot axis which extends substantially vertically when the head body rests on a horizontal surface, the head body being configured to occupy, with respect to the connecting member, at least a main operating position in which, when the connecting member is mechanically connected to the suction tube and the pivot axis extends vertically, the head body has a lateral bulk, measured according to a measurement direction which is horizontal and perpendicular to the suction tube, having a first bulk value, and a pivot position in which, when the connecting member is mechanically connected to the suction tube and the pivot axis extends vertically, the head body has a lateral bulk, measured according to the measurement direction, having a second bulk value which is lower than the first bulk value, characterized in that the suction head further includes a motor-driven drive mechanism including a drive motor configured to drive the head body in rotation relative to the connecting member and about the pivot axis, the motor-driven drive mechanism being configured to displace the head body at least between the main operating position and the pivot position. - a head body provided with a lower face which is configured to be directed towards a surface to be cleaned, and with a suction opening leading into the lower face of the head body, - a connecting member which is fluidly connected to the suction opening and which is configured to be mechanically and fluidly connected to a distal end portion (15.1) of a suction tube of a vacuum cleaner, the head body being pivotably mounted relative to the connecting member about a pivot axis which extends substantially vertically when the head body rests on a horizontal surface, the head body being configured to occupy, with respect to the connecting member, at least a main operating position in which, when the connecting member is mechanically connected to the suction tube and the pivot axis extends vertically, the head body has a lateral bulk, measured according to a measurement direction which is horizontal and perpendicular to the suction tube, having a first bulk value, and a pivot position in which, when the connecting member is mechanically connected to the suction tube and the pivot axis extends vertically, the head body has a lateral bulk, measured according to the measurement direction, having a second bulk value which is lower than the first bulk value, characterized in that the suction head further includes a motor-driven drive mechanism including a drive motor configured to drive the head body in rotation relative to the connecting member and about the pivot axis, the motor-driven drive mechanism being configured to displace the head body at least between the main operating position and the pivot position. the head body being configured to occupy, with respect to the connecting member, at least a main operating position in which, when the connecting member is mechanically connected to the suction tube and the pivot axis extends vertically, the head body has a lateral bulk, measured according to a measurement direction which is horizontal and perpendicular to the suction tube, having a first bulk value, and a pivot position in which, when the connecting member is mechanically connected to the suction tube and the pivot axis extends vertically, the head body has a lateral bulk, measured according to the measurement direction, having a second bulk value which is lower than the first bulk value, characterized in that the suction head further includes a motor-driven drive mechanism including a drive motor configured to drive the head body in rotation relative to the connecting member and about the pivot axis, the motor-driven drive mechanism being configured to displace the head body at least between the main operating position and the pivot position.
