We’re getting closer to a robot vacuum that can climb stairs

With the ability to lift itself up to get over room transitions as high as 40mm, fluffy rugs, and other possible obstacles, Roborock's new Qrevo Curve could be a sign that the stair-climbing robot vacuum is almost here.
To be clear, Roborock hasn't said this, but based on how fast this company - and others - are innovating in this space, it feels like we're really not that far away. SharkNinja also announced a new robot vaccum with lifting capabilities this week, and the other companies are likely not far behind.
Whether we need stair-climbing robovacs is a question I'm not sure I have the answer to yet.
