FIELD: process engineering.
SUBSTANCE: invention relates to surface washing head. Said head has case shaped to cowl open downward. At least one spraying sleeve is arranged inside said cowl to revolve therein about rotational axis. Said sleeve has atomiser spaced from rotational axis to feed pressurised liquid detergent and revolves along with said spraying sleeve to wash the surface by fluid jet. There is protective disc to cover at least one spraying sleeve on case exposed bottom side to define fluid jet circular passage penetrated by retaining baffles. At least one spraying sleeve can turn relative to protective disc. Retaining baffles are irregularly arranged in circle to allow noise reduction in proposed head.
