A nozzle arrangement including a brush provided with brush elements having tip portions for contacting a surface and picking up dirt and/or liquid during rotation of the brush about a brush axis, a driving mechanism for rotating the brush, a first deflector element with a first deflector surface that extends substantially parallel to the brush axis and that interacts with the brush during the rotation of the brush for releasing the picked-up dirt and/or the liquid particles, and a second deflector element that is spaced apart from the brush and the first deflector element, the second deflector element having a second deflector surface that is oriented at an angle to the first deflector surface, wherein the second deflector surface deflects the dirt and/or liquid particles, which are released from the brush at the first deflector surface, into an exhaust channel that begins between the first and second deflector elements.

Cleaning device having a nozzle for cleaning a surface

The present invention relates to a nozzle arrangement () for a floor cleaning device (), comprising a nozzle housing (); a brush () rotatable about a brush axis (), wherein the brush () is partially surrounded by the nozzle housing () and protrudes from a bottom side () of said nozzle housing (), said brush () being provided with brush elements () for picking up dirt and/or liquid particles () from a surface to be cleaned () during the rotation of the brush (), and a protection assembly () for preventing obstacles () from getting sucked into the nozzle housing () or wrapped around the brush (), wherein said protection assembly () is arranged within the nozzle housing () and comprises a plurality of spaced apart ribs () that extend at least partly through the brush (), wherein a suction channel () is defined between a back end () of the ribs () and an opposite inner wall element () of the nozzle housing (), wherein said back end () of the ribs () is facing away from the brush axis () and said inner wall element () is facing towards said back end () of the ribs () and spaced apart from said back end (), and wherein the brush elements () extend at least partly into the suction channel () during the brush's rotation.
