Corner Cleaning (Robot)

Corner performance is consistently strong, aided by an extending side brush and edge-focused behaviors that improve coverage in tight angles.

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 overall corner performance is viewed as above average.

Corner performance benefits from the extending side brush and edge behaviors; reviewers commonly report corners and tight spots are handled better than average.

Corner performance is consistently praised due to an extendable side brush that reaches into 90-degree corners more effectively than typical round robots. Several reviews call corner coverage a meaningful advantage.

Corner performance is frequently credited to the extendable side brush; it improves reach compared with fixed brushes, though the round body still can’t fully clean the tightest corner points.

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

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 messes.

Corner performance is generally strong thanks to an extendable side brush and edge-reaching mop pad, though at least one review still reports weaker vacuum pickup in tight, powdery corners.

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 work.

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.

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.

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.

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 area cleaning or a second pass typically corrects this.

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

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.

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 reach.

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 hard floors.

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.

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

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

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 scenarios.

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 the very edge in some cases.

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.

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 open corners than in cluttered zones.

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

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

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.

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 corner reach.

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 a lot along edges.

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.

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.

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.

Corner cleaning is the tradeoff of the round body: it can sweep along edges, but multiple reviews note 90° corners can retain debris because the side brushes don’t fully reach in.

Corners are average: it can sweep near corners, but several notes mention it may miss debris in tight corner pockets or very close to the apex.

Corner performance is decent for a round robot but not perfect; reviews suggest it can miss tight corners and may need occasional manual touch-ups.

Corner cleaning is inconsistent: vacuuming corners can be strong thanks to dual side brushes, while mopping corners may still miss without an extending pad.

Corner cleaning is typical for the category: acceptable for maintenance, but corners may still need occasional manual touch-ups, especially with larger or smoother debris.

Corner pickup is often good but not perfect; multiple demos show small leftover debris in corners compared to robots with extending arms or more aggressive edge tooling.

Corners are a mixed bag: the D-shape helps approach, but several tests note the robot can bump or take wide turns and still leave corner debris behind.

Corners remain a weak spot in several tests; the edge features help, but some users still needed a handheld vacuum for tight corners.

Corner cleaning is adequate but not class-leading; multiple reviews mention missed debris in tight corners or along awkward nooks.

Corner cleaning is a recurring limitation, with some reports of leftover debris in corners where a round robot cannot fully reach.

Corner reach is decent thanks to the side brush, but several reviewers note that larger debris can get pushed around or into corners rather than cleanly captured on the first pass.

Corner cleaning is a known limitation: as a round robot with a single side brush, it can miss tight corners or smear debris in corner flour-style tests. Edges and open perimeters are better than sharp corners.

Corner reach is a known weakness for round robots without extending arms; at least one comparison specifically places it near the bottom for corner/under-cabinet edge mopping.

Edge/corner performance is a noted limitation in some reviews, with the single side brush and robot geometry leaving corners less thoroughly cleaned than open areas.

Corner cleaning is a common weakness: like most round robots without an extending side brush, it cannot fully reach square corners and can leave sand or litter behind. Extra passes can improve results, but it is not a substitute for a manual edge tool.
