Edge and corner cleaning is usually where robot vacuums fall short. The Saros 10R actually does something about it.
The FlexiArm Trick
Most robot vacuums have fixed brushes that can only reach as far as the robot body allows. The Saros 10R has extending arms that push both the side brush and mop pads outward when it's cleaning along walls.
Think of it like this: the robot hugs the wall, and the brush reaches around the corner to grab debris that a fixed brush would miss. Same deal with the mop pads. They extend to actually clean along your baseboards instead of leaving a dry strip.
Does It Actually Work?
Yes, noticeably better than most robot vacuums. Reviewers testing the Saros 10R found clean edges and minimal debris left in corners. People coming from other robot vacuums specifically call out edge cleaning as a strength.
The Reality Check
It's still a round robot trying to clean square corners. Basic geometry means it can't reach every single millimeter of a 90-degree angle. Very tight corners might still need occasional attention.
But the improvement over standard robot vacuums is real and substantial. Most owners find they don't need to follow up along edges anymore, which was a constant annoyance with previous robots.
See for Yourself
The Roborock app shows exactly where the robot cleaned. You can look at the coverage map and see if any corners consistently get missed. Then you'll know which spots need occasional manual attention.
