A suction nozzle for a portable hard surface cleaning apparatus includes a suction nozzle housing having a first and a second housing half-shell which between them form a suction duct which extends from a suction opening to a suction duct end section to which a source of vacuum can be connected for creating a suction flow. Arranged at the suction opening is a replaceable squeegee lip, and the two housing half-shells each have at least one holding element adjacent to the suction opening, and a holding section of the replaceable squeegee lip is arranged between the holding elements of the two housing half-shells. In order to improve the suction nozzle in such a manner that it is reliably held at the suction opening, the holding elements in each case form an engagement with the holding section.
