Do Android Model Series Help Convey An Android's Intended Function?

Do android model series help convey an android's intended function?

Androids with similar model series and similar functions:

AP400 and AP700 are both home assistants AX400 and AX700s are also both home assistants RK800 is designed for forensics and police work and Amanda says RK900 will make him obsolete

Adroids with similar model series and dissimilar functions:

WB200 is outdoor and agricultural work (Rupert), WB400 is heavy unitdesigned for dock work WG100 is city maintenance, WG700 is janitor WR400 is intimate partner, WR600 is city maintenance worker for green spaces

Androids sorted by function:

Intimate partners: BL100, WR400, HR400 Home Assistants: AP400, AP700, AX400, AX700, CX100, HK400, KR200, MP500, PL600 Childcare: AX400, EM400, PL600 Customer Service: AV500, VB800, VH500, VS400 Sports Partner: AC700 Entertainment: EM400, JB300, QB1000 Security/Police: GJ500, GS200, PC200, PM700, RK800, RK900 Medicine: KL900, MC500 Education: PJ500 Being Smart (research units): RK200, RT600 Combat: SQ800 Secretarial: ST300 Heavy manual labor: TR400, TW400, WB400, WM500 Outdoor and Agricultural: WB200, WR600 Bear: URS12 Delivery: WD500 Maintenance: WG100, WR600 Janitor: WG100, WJ700, WR600 Child: YK500

Androids with the exact same function but different sex can change model series:

Female PM700 to Male PC200 Female WR400 to Male HR400

Conclusion:

WR400s (North) and WR600s (Ralph) have the same model series but very different functions. There are seven different model series all assigned to the same task (home assistance.)

Androids with the exact same function but with physical differences (physical sex) change model series.

I’ve used model series indicating function as a thing in fanfiction before, and will continue to do so, but it doesn’t look canon!
