Abstract: A tool (802) adapted to be carried by a tool holder (160) provided in a robotic work tool (100), the tool (802) comprising a slit (801; 901) arranged to receive a pin (804) for attaching said tool (802) to said tool holder (160), wherein said tool (802) is movable such that the pin (804) may be displaced within the slit (801; 901) and wherein the slit is symmetrically located within the tool (802) with respect to at least one of the length and the width of the tool.

Abstract: A device for a dishwasher comprising a tub with a bottom (10) which is provided with a sump (11) for collecting liquid circulating in the tub. When the machine is emptied, the liquid is distributed from the sump to the inlet side of a sewage pump (20) from which the liquid is discharged to a sewer or the like. In order to make the overall height of the machine small, to limit the quantity of watr remaining in the sump, and to considerably decrease the working time of the sewage pump necessary to achieve this small quantity, the bottom surface of the sump (11) is placed below or on the same level as the pump housing (23), and the inlet (21) of the pump communicates with the sump via a pipe (17) which has a restriction (26).
