One minute, she's acting in character, full of herself, with her desires and values and a sense of self-worth (like a most desirable and MOST unobtainable real human)... but in a flash, on command, the Fembot drops her public performance as a very particular person, in contrast becoming for example an ideal, adoring, less-than-human bimbo.
For me, many, many fembot porn videos don't have enough of these subtle, ironic contrasts. Sparking glitches and repeating, spastic jerks certainly reveal the robot within; but so would:
- a sudden feat of mathematical calculation, or a perfectly coordinated catch
(and she fails to notice, or understand how inhuman she's acting)
- being told she's a robot; but her response shows, she's programmed to completely not understand the concept of robots; and to get giggly horny the more it's unsuccessfully explained to her.
- ANY inhuman non-sequitur can keep the ironic, erotic momentum of seduction going... from tiny hints (like saying a phrase that the viewer heard spoken when the fembot wasn't around; or speaking a phrase in a foreign language); or the "programmed glitch" can be a dead giveaway... continuing to prattle on adorably, though her mouth is entirely occupied and otherwise busy.
Ludella Hahn understands the dynamic power of fembot irony. Her performances embody the ways a fembot entices us, flirting by gestures which betray her as an automaton (assuring the viewer that they'll have full access to the fembot).
You may have been reminded of other performers whose videos work because they exploit those differences between what the viewers understand, and what the fembot can't; and any other mismatches between the grasp of the fembot, and that of others in the story, whether that's a human male, human female, or another fembot.
A fembot can be perfect; and programmed to never understand how that can even be true.

Erotic irony is her dynamic: she has no real understanding, and no power... but that dynamic stirs up some powerful erotic feelings in the viewer!
