Housekeeping refers to the management of duties and chores involved in the running of a household, such as cleaning, cooking, home maintenance, shopping, and bill payment. These tasks may be performed by members of the household, or by other persons hired for the purpose. The term is also used to refer to the money allocation for such use. By extension, an office or organization, housekeeping includes house cleaning, that is, disposing of rubbish, cleaning dirty surfaces, dusting and vacuuming. It may also involve some outdoor chores, such as removing leaves from rain gutters, washing windows and sweeping doormats. The term housecleaning is often used also figuratively in politics and business for the removal of unwanted personnel, methods or policies in an effort at reform or improvement.

Housecleaning is done to make the home look and smell better and to make it safer and easier to live in. Without housecleaning lime scale can build up on taps, mold grows in wet areas, smudges appear on glass surfaces, dust forms on surfaces, bacterial action makes garbage disposal and toilet smell and cobwebs accumulate. Tools used in housecleaning include vacuums, brooms, mops and sponges, together with cleaning products such as detergents, disinfectants and bleach.
