A Universal Anything PHK Household Services Expert specialized in household cleaning. The PHK is a mid-high end service Doll produced by Universal Anything Services. Unlike Dolls which are primarily marketed to individual households, the PHK can cover a much wider range of services. They can accommodate any cleaning request from their clients, from individual rooms to massive public venues. Work of this scale requires a certain degree of professional technique, and the high unit cost combined with the lack of frequent usage leads to extremely low cost-efficiency, which makes them unsuitable for individual purchase. As a result, these Dolls are generally not directly marketed, instead being made to order in batches by UAS in response to requests from intermediary platforms or rental companies. Jessie is not a test subject - she joined Project Neural Cloud as a member of the logistics staff. "I've got everything together, time to begin! I won't leave a speck of dirt behind!"
