There is disclosed an improved cleaning device, and in particular, substrate cleaning device. Substrate cleaners are used to prepare substrates, such as printed circuit boards, prior to further processing to ensure that the substrates are free from contaminants such as dirt, dust, grit and the like. Known cleaners are not very robust and have a complex engaging mechanism. The invention provides a chuck (40) for inserting into a bore of a body (30), the chuck (40) comprising: a main body; an engaging means (48, 50) carried by the body; and an actuating means (52) for selectively moving the engaging means (48, 50) between an engaged state and a disengaged state, whereby, in use, in the engaged state the engaging means is urged against the interior surface of the bore to hold the chuck (40) within the bore, and in the disengaged state the engaging means (48, 50) is retracted from the interior surface of the bore to allow release of the chuck (40). |
