Best Roborock Vacuums for Corner Cleaning (Robot)

#1

Corner cleaning was a clear strength because the extendable mop reached into corners and along edges.

#2

Corner cleaning gets frequent praise thanks to an extending side brush, improving reach into tight corners. One stress test notes the side brush can scatter debris in extreme scenarios, but...

#3

Corner cleaning benefits from the extendable side brush, though it tends to deploy only when a true corner is detected.

#4

Corner cleaning was often excellent, though one Business Insider corner-flour test found it weak.

#5

Corner cleaning is usually strong thanks to extending brushes and mop arms, but a few tests found small misses or imperfect coverage.

#6

Corner cleaning was generally strong thanks to side brush and side mop behavior.

#7

Corner cleaning improves with the extending side brush and edge mop, and several sources call it better than prior generations, though not perfect in every tight-space scenario.

#14

Corner cleaning is mostly praised thanks to the extending brush and mop pad, though one review found it failed to get as close to corners as expected.
