Claims (18)

1 . A motorized suction head comprising:

a main body;

a roller, the roller being rotatable and being configured to rub a surface to be cleaned;

an electric motor;

a battery and/or a transformer electrically connected to the electric motor;

a transmission configured to connect the roller to the electric motor so as to rotate the roller;

wherein the suction head further comprises a fluid dispensing device configured to dispense a fluid;

wherein the fluid comprises steam and/or comprises a liquid with a cleaning substance and/or a disinfectant substance;

wherein the fluid dispensing device comprises a perforated tube comprising holes for the outflow of the fluid and a T-piece with a hose connection;

wherein the perforated tube is mounted in front of the main body of the suction head and extends substantially over an entire width of the suction head.

2 . The motorized suction head of claim 1 , further comprising a front protective casing for protecting the perforated tube from impacts and/or contact with the user.

3 . The motorized suction head of claim 1 , wherein the perforated tube is configured to rotate from a first working configuration wherein the perforated tube is in front of the main body of the motorized suction head to a second configuration wherein the perforated tube is above the main body of the motorized suction head.
