Abstract: A vacuum cleaner utensil comprises a plurality of elements (Lx) flexibly mounted to a central area (C) to provide a suction opening at a side of the central area (C) corresponding to a current movement direction (MD) of the vacuum cleaner utensil out of a plurality of possible movement directions, while reducing a possibility for air to enter the central area (C) from a plurality of other directions. The central area (C) may rotate around its 5 center. The elements (Lx) may rotate with reference to respective axes (A) provided on the central area (C). The elements may be mounted to a single axis (Ac), and have a flexible first part having a first thickness, followed by a second part having a second thickness exceeding the first thickness, wherein—when pushed together as a result of movement—the second parts of neighboring elements (Lx) reduce a possibility for air to enter the central area (C) from 10 between the neighboring elements (Lx).

Abstract: A surface cleaning device comprises a brush (B) that is curved at least partially around a center part (CP) of the surface cleaning device, a deformability of the brush (B) determining a deformability of an outer circumference of the surface cleaning device. The brush (B) has a rotation axis (A), which is curved at least partially around the center part (CP) of the surface cleaning device. The rotation axis (A) is parallel to the surface. The brush (B) may be a donut-shaped brush (B) fully around the center part (CP) of the surface cleaning device. The surface cleaning device may have an electrical motor (M) for driving the brush (B). The center part (CP) may comprise a container (DC) for collecting dirt swept from the surface by the brush (B). The center part (CP) may have an edge (E) for bending the brush (B), dirt being released from the brush (B) at an end of the edge (E) where the brush (B) is relaxed. The center part (CP) may have an upper rim (R) for keeping the brush (B) at its position.
