Abstract: Provided are a roller device (100) and a cleaning apparatus (200). The roller device (100) includes a main support (1) having a roller groove (10) and a roller assembly (2) including a roller (21), a locking component (22), and an ejection component (23). The locking component (22) is connected to the roller (21), and has a first position where the locking component (22) is locked to the main support (1) and a second position where the locking component (22) is released from the main support (1). The ejection component (23) is disposed at the main support (1) or the roller assembly (2) and configured to provide a force for the roller (21) to move out of the roller groove (10). In the cleaning apparatus (200) having the roller device (100), the roller device (100) is simply and conveniently removed and mounted in a labor-saving manner, and the roller (21) is locked more reliably, which can effectively avoid sliding-out of the roller (21) in non-use. Therefore, user experience is satisfactory.
