A nozzle for use with a surface cleaning apparatus is disclosed, the nozzle comprising: a nozzle housing defining a dirty air inlet; at least a first caster coupled to the nozzle housing to allow the nozzle housing to move over a surface to be cleaned; and a caster locking device, the caster locking device being coupled to the nozzle housing. The caster locking device preferably includes at least a first locking member that transitions the first caster between a locked configuration that restricts movement of the nozzle housing along a single axis during a cleaning operation and an unlocked configuration that restricts movement of the nozzle housing along a single axis during a cleaning operation. And the unlocked configuration allows movement of the nozzle housing along a plurality of axes/directions during a cleaning operation.
公开了一种与表面清洁设备一起使用的管嘴,所述管嘴包括:管嘴外壳,所述管嘴外壳限定脏空气入口;至少第一脚轮,所述至少第一脚轮联接到所述管嘴外壳以允许所述管嘴外壳在待清洁表面上方移动;以及脚轮锁定装置,所述脚轮锁定装置联接到所述管嘴外壳。所述脚轮锁定装置优选地包括使所述第一脚轮在锁定配置与解锁配置之间转换的至少第一锁定构件,其中所述锁定配置限制所述管嘴外壳在清洁操作期间沿单个轴线的移动,并且所述解锁配置允许所述管嘴外壳在清洁操作期间沿多个轴线/方向的移动。
