Suction nozzle and hard-surface suction apparatus

The aim of the invention is to provide a suction nozzle, in particular for a portable hard-surface suction apparatus comprising a suction device, the suction nozzle having a suction opening connected to a suction channel, wherein the end of the suction channel facing away from the suction opening can be or is connected to the suction device, wherein, additionally, a first coupling unit is arranged or formed at the suction nozzle for the pivoted coupling with a second coupling device arranged on or formed at the hard-surface suction apparatus in order to improve at least a rotational or pivot axis such that, in particular, the manipulation thereof is improved in the ground-deep cleaning of vertical hard surfaces. In order to achieve said aim, it is proposed that the at least one rotational or pivot axis extends transversely to the suction opening. The invention further relates to an improved hard-surface suction apparatus. 种吸嘴，特别是用于包括吸净装置的便携的硬面吸净设备的吸嘴，该吸嘴具有抽吸开口，抽吸通道连到该抽吸开口上，抽吸通道的背离抽吸开口的抽吸通道端部与吸净装置连接或能连接，其中，在吸嘴
