#13

Corner cleaning is strong thanks to the extending side brush and mop reach.

#14

#15

Corner cleaning benefits from an extending side brush, though independent tests suggest the robot can still leave perimeter gaps depending on the run.

#16

Corner cleaning is a standout due to an extendable side brush, with strong results reported in tests. Still, corners may occasionally need a second pass for perfection, especially after heavy...

#17

Corner reach is better than typical thanks to an extending side brush/mop, though some edge areas can still be missed—especially on carpet where the side brush does most of the...

#18

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.

#19

Corner performance is often praised thanks to the rounded-square shape and extending arms/brushes that reach further into corners. Minor leftover particles can still appear along edges in cluttered rooms.

#20

Edge and corner cleaning is a highlight due to an extendable side brush; most reviews praise edge reach, though one notes some leftover debris at corners.

#21

Corner cleaning is generally good, with TruEdge and roller extension helping, but one reviewer still says corners need occasional manual work.

#22

Corner performance is frequently highlighted as strong due to the FlexiArm side brush and extendable mop behaviors. Some video testing shows occasional corner misses on a first attempt, but targeted...

#23

Extending side brush improves corners, but tiny crumbs can still remain.

#24

Corner performance is strengthened by the extendable mop approach; reviewers show it reaching closer along cabinet lines and tight areas than typical fixed-pad designs.

#25

Corner cleaning improves notably thanks to an extending side brush, leaving corners visibly cleaner than many robots. Some reviews still note a small amount of leftover debris in tight corners.

#26

The robot’s shape and edge-focused mop extension help it reach corners better than many round bots, though some reviewers still wish for an extending side brush for even deeper corner...

#27

Corner cleaning is frequently praised due to an extending brush/edge mechanism that improves reach into corners compared to many round robots. Corner coverage is commonly noted as a strength on...

#28

Corner performance is often better than expected, even when the robot lacks an extending side brush, and TruEdge-style behavior helps it reach into edges while mopping. Some scatter tests report...

#29

Corner cleaning is repeatedly praised thanks to an extendable side brush and edge-focused routines. Reviewers describe better corner reach than robots that rely on a fixed brush setup.

#30

Corner performance benefits from the side brush, but like many robovacs it may flick debris and occasionally leave small misses in tight corners.

#31

Corner cleaning is described as solid, with good reach into corners for a robot in this class.

#32

Corner reach is better than typical due to the extending side brush, but ultra-tight corners can still be missed occasionally depending on layout and avoidance settings.

#33

The extending corner arm improves edge reach on hard floors and in corners, though carpet edges remain more limited than the center path.

#34

Corner performance is generally strong when TruEdge/edge features engage, but not flawless. Some reviewers still want more side-brush reach into deep corners and report occasional leftover debris in tricky corner...

#35

Corner performance is above average for a round robot thanks to effective edge behavior, but it still can’t fully reach tight 90-degree corners. Side-brush behavior can leave small leftovers at...

#36

Corner cleaning was mostly good thanks to extending brushes and mop reach, though several reviewers still found corners less consistent.

#37

Corner cleaning is above average for the class thanks to the side brush and orderly edge-first patterns, though truly tight corners can still leave a small amount behind.

#38

Corner performance is mixed: the extending side brush can improve reach, but several reviews still show misses in tight corners or around furniture legs. It tends to do better in...

#39

Corners remain a common limitation (round body + geometry), even though edge cleaning is strong.

#40

Corner coverage is generally rated positively for a robot, with the usual limitations around tight corners and cluttered edges.

#41

Corner and edge pickup is helped by its side brush and edge-focused routines, but at least one long-term test noted side-brush durability or looseness concerns.

#42

Corner cleaning is helped by the general design and dual side brushes in some descriptions, but at least one reviewer notes it can intentionally keep distance from walls/furniture, reducing true...

#43

Corner results are mixed: some reviewers see improvement, while others note the side brush and geometry do not always reach tight corners as well as the best robots.

#44

Corner results were split: some reviewers praised side brushes and wall reach, while another noted the side brushes do not swing out for true corner cleaning.

#45

Corner performance is described as acceptable but not class-leading. Several reviews point to the lack of extendable brushes/pads as the limiting factor, even though the robot’s perimeter passes still catch...

#46

Corner performance is inconsistent: some owners report it reaches corners well, while others say it misses corners or keeps a noticeable distance from furniture, leaving uncleaned wedges.

#47

Corner cleaning is helped by the side brush and repeated passes; it can eventually clear corners, but it may flick debris and require time to fully finish edges and corners.

#48

Corner cleaning improves with edge air-blasts and pad reach, yet multiple reviews still recommend a quick manual touch-up for tight corners.

#49

Corner/edge behavior is decent but not elite; some tests and owners note it can miss fine debris in corners and along edges compared with higher-end robots.

#50

Corner cleaning is mixed: one review praised the corner reach and air assist, while one critic preferred an extending brush.
