I have heard in the name of one posek that vacuuming carpets is forbidden during the Nine Days (between 1 Av and 9 Av, following Ashkenazic custom) since this is equivalent to laundering. Is this something that is generally accepted? Are there perhaps other poskim who explicitly allow it?
Edit: This view is recorded in the recently published Kovetz Halachos, a compendium of the rulings of Rav Shmuel Kaminetsky. The reasoning is that we find with regard to Shabbos that one violates the melachah of 'libun' (whitening/cleaning) simply by removing dirt, even without using water (see Orach Chayim siman 302). This is further supported by the ruling of Igros Moshe that dry cleaning may not be done in the Nine Days, even though it does not involve the use of water. Does anybody know of other sources which might discuss this?
