答案

cleaned.
解析：have sth.done 的结构
have sth done 就是使某物成一种...的状态.
混淆点：
理解这种结构最好的办法是理解他们的意义.这是一种have引起的一种动词+宾语+宾语补足语的结构.这种结构中,宾语和宾语补足语有逻辑上的主谓关系.
have sth doing即doing是sth发出的动作,为主动.
have sth done即sth是done的逻辑主语,但是被动的.例如：
I have had my watch repaired.中,watch 是被修的,故用过去分词表被动.
I had him doing the work all night long.中,him 是doing的施动者,是主动,但表持续动作,故用现在分词.
I had him carry the box for me.中,跟上句一样,表主动,只是do表动作的完成,不表进行,故用省to的不定式.
