From The Sims Wiki, a database for The Sims series that anyone can edit
The Cleaning skill is one of the seven main skills in The Sims 2 that a Sim can build up. Cleaning skill points can be gained by tidying up the mess which occurs during daily life (for instance, washing counters, appliances, toilets, sinks, and mopping) or by reading a book. You can also gain Cleaning skill points by certain career rewards.
There are several career tracks that focus on building the Cleaning skill in order to get a promotion, such as: Culinary, Medicine, Science, Natural Science (available with the University expansion pack) and Education. For teenagers, having a high Cleaning skill (level eight or higher) will earn them the §750 Kim Metro Prize for Hygienics, one of several scholarships available with the University expansion pack.
