By constructing tank cleaning equipment according to the invention such that it comprises a cleaning jetting part (7, 9) as well as a suction part (4), the equipment can work with the same cleaning medium which is recirculated. This saves supply of fresh cleaning medium, and since used medium is thus not discharged, it is not necessary to establish deposit facilities to avoid pollution. Furthermore, this equipment according to the invention may advantageously be used for keeping so-called drilling mud in a mixed and thus ready-to-use state, even when left to stand for an extended period of time in a tank. The nozzle jets (10) thus keep the mud in the tank in a constantly mixed state, and the mud can therefore be sucked through the suction pipe (20) for pumping in the drill pipe, it being ensured that the mud is homogeneous and has a suitable viscosity.
