Could someone explain the ROB matchup?

Apparently it's strongly in ZSS' favour. I'm not arguing agaisnt it, but could someone please explain why it's so advantageous fo ZSS? I'd appreciate it.

For one, she has a stationary infinite on him.

Otherwise, I have never played a ROB with my Zamus... But I assume the whip spacing along with her speed helps a lot.

She combos him really well, she's fast enough to get in past his walls, and she outranges him. Oh and she punishes his gaping hole underneath him badly with uair. Basically, she's perfectly suited to weaken his strengths and take advantage of his weaknesses.

ZSS thrives in the area where ROB has no options. At her best distance, she is too close for ROB to safely spam projectiles, but she is too far away for him to hit her with ftilt and not present an opening. Thence, she can put him in the air, and he's completely open; her uair breaks ROB's game apart from below. Furthermore, ROB is a big target, so ZSS doesn't need exceptional aim to juggle him all day. To top it all off, ROB's recovery is fairly predictable, and he can't airdodge out of Robo Burner, making him very easy to hit while he's recovering.

Finally, although it's not really all that important to the match-up, one dsmash should mean a lost stock for ROB.
