ABSTRACT:
Cleaning apparatus for the glazing in an atrium-type roof structure (10) comprises an elongate brush (14) rotating about its axis and mounted at opposite ends in carriages (18, 20) running on guide rails (16, 16A) which can move non-synchronously so as to change the angular orientation of the brush, which is formed with two telescopic parts (22, 24) to enable it to change its length as its angular orientation changes (FIGS. 1 and 3). Also described is apparatus for cleaning a barrel arch-type glazed roof structure.
