It doesn't work on stairs unfortunately. It senses there's a drop and moves away. I recommend a small handheld vacuum for the stairs.

It cannot be used on stairs but it will sense when it approaches a drop off, such as a step, and turns away. It will not fall down the stairs.

Knows when its near the stairs, that it stops and continues working without ever falling off. Modern technology at its best!

The Roomba 650 has a feature that prevents it from going/falling down stairs.

Really good but you need to get one for each step
