Is a cleaning lady (non-Jewish) allowed to clean the house on Tisha Be’Av?
Answer:
Yes, she may clean the house. The Aruch Hashulchan 559:9 writes that one should not clean the house until after chatzos, and preferably the entire day. It would seem this refers to by a Jew who will remove his mind from the mourning. A non Jewish worker would not be a problem.
