Even the corners are wiped reliably.
The arm with the mops swivels skilfully into the corners and reaches even hard-to-reach areas.

I got myself the X40. I hope I'll be happy with it because the Roborock S8 was unnecessary.

It also wipes corners and edges wet. But there is a gap - not regular - sometimes smaller, sometimes larger. Certainly not like wiping by hand - but sufficient for my needs

It goes perfectly into any corner thanks to the flip-out side brushes.

Yes, the Dream X50 wipes the corners and edges wet. With its extendable mops, the robot can keep its body at a sufficient distance from the wall so that it does not come into contact with the wall.we have fun with our X50.good luck with your decision. MFG Marco

The robot also mops the corners and edges and also approx. 3-4cm under low furniture under which the robot cannot drive.
This is possible because the robot can extend the mop.
