Feedback
What reviewers found
Vacuum Wars measured strong cleaning, and PCWorld liked it in routine use, along with the slim body and edge reach. They tell different stories on dried stains: the lab score was high, while PCWorld needed several passes on coffee and ketchup. Both found small-object avoidance and taller thresholds limiting. Only Vacuum Wars measured carpet pickup, so its strong numbers are a good sign from one test rather than a result anyone has repeated.
Vacuum Wars, lab test, A few weeks of evaluations on a bought unit, Aug 2026 · PCWorld, hands-on, Sept 2026
Hard floors
Not enough evidenceOnly Vacuum Wars measured hard-floor pickup, finding it swept debris of all sizes very well without scattering fine dust. PCWorld didn't report separate hard-floor results.
Carpet and rugs
Not enough evidenceOnly Vacuum Wars measured carpet cleaning, recording one of the best embedded-sand results it has seen. PCWorld found short pile easy to cross but didn't test pickup.
Pet hair
Reviewers rate it highlyVacuum Wars measured above-average pickup of hair pressed into carpet and no long hair wrapped round the split brush. PCWorld also found the split brush effectively reduces tangles and counts it an advantage in pet homes.
Mopping
Reviewers rate it highlyVacuum Wars scored its dried-stain cleaning well above average while leaving less water behind than most. PCWorld found routine mopping good and liked the swinging pad along edges, though dried coffee and ketchup needed several passes.
Navigation and obstacles
Mixed resultsVacuum Wars found it covered floors faster than average but found its obstacle avoidance below average. PCWorld saw bowls and toys usually spotted but thin cables and flat objects missed, and it couldn't climb a sill just over 2cm.
Dock and upkeep
Reviewers rate it highlyVacuum Wars rated the upgraded dock, which empties the bin, hot-washes and dries the pads. PCWorld liked the removable wash basin, but notes there's no detergent tank, so cleaner goes in by hand.
App and software
Reviewers rate it highlyVacuum Wars calls Roborock's app one of the best in the business, and PCWorld found everyday settings easy to find despite deep customisation, with automatic room division after mapping.
Noise
Not enough evidenceNone of the reviews we use has tested its noise yet.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term or judged Roborock's support yet.
Value
Reviewers rate it highlyVacuum Wars ranks it alongside flagships that cost much more and notes it's often on sale, and PCWorld found it appealing at its current price for homes with low furniture.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Outstanding on carpet and pet hair
Vacuum Wars measured 94% of embedded sand removed from carpet, against 85% for the original Edge and a 78% average, which it called one of the best results it has recorded. Pet hair pickup rose to 89.5%, and no long hair wrapped round the split brush. PCWorld also rates the split brush as an advantage in homes with pet hair. If carpet is your main floor, this is the headline reason to buy it.
Mops well without soaking floors
Vacuum Wars scored its dried-on stain cleaning well above average and found it left less water behind than most, so there's less risk of streaks. PCWorld found routine mopping good, but dried-on coffee and ketchup needed several passes or more water, and says roller-mop robots shift that kind of grime better. The swinging mop gets close to skirting boards, which PCWorld counts as a real plus in homes with lots of corners.
Low body, low climbing
The turret drops so the robot fits under low furniture, and Vacuum Wars measured faster-than-average coverage of its test floor. That doesn't prove it finds its way just as well on every route with the turret lowered. Thresholds are the problem. PCWorld watched it fail a sill just over 2cm between bedroom and hallway, even after marking it in the app, and Vacuum Wars also lists about 20mm as its limit. Measure your doorway thresholds before you buy; there's no lifting chassis to help.
Clear the floor first
Vacuum Wars recorded 14 of 24 obstacles avoided, below its average and slightly worse than the original Edge. PCWorld found it usually spotted food bowls and dog toys and steered round chair runners, but thin cables and very flat objects caught it out, especially near walls. Neither suggests leaving it alone with cables or pet mess. A quick tidy before each run is part of owning this one.
The dock does most of the chores
The dock washes the pads at 80°C, dries them with warm air and empties the bin into a bag Roborock says lasts about 65 days. PCWorld points out there's no detergent tank, so cleaner goes into the water by hand. Vacuum Wars flags the small 240ml onboard bin, which can fill before the robot returns in a shedding home, and a battery that drains a little faster than average, though quick routes make up for it.
Our take
Should you buy the Qrevo Edge 2?
Best for: Homes with carpet, hard floors and a pet that sheds. Skip it if: Your floors are cluttered or separated by raised thresholds.
The Edge 2 is worth considering for clear floors, low furniture and carpet: Vacuum Wars' pickup results were strong, although it is the only cited test measuring carpet cleaning. Thin hazards and tall thresholds need attention. The Saros 10R avoided clutter better but had mixed carpet-hair results. The Curv 2 Pro adds a lifting chassis, but check the shape of your thresholds rather than relying on the maximum claim.
The Qrevo Edge 2 is the second go at Roborock's upper-mid-range Edge, and the big change is that the sensor on top now sinks into the body, so it's just under 8cm tall. It keeps the extending side brush and mop for skirting boards, a split brush to stop hair wrapping and a dock that washes the pads in hot water and dries them. There's no lifting chassis, so doorway thresholds much over two centimetres stop it, and no detergent tank.
Vacuum Wars measured 94% of embedded sand removed from carpet, one of the best results it has recorded, with above-average pet-hair pickup and no long hair wrapped on the brush. It scored the dried-stain mopping well above average with less water left behind than most. PCWorld found routine mopping good and the swinging pad useful along edges, though dried coffee and ketchup needed several passes. Both agree on the catches. PCWorld watched it fail a sill just over two centimetres even after marking it in the app, and found thin cables and flat objects missed, while Vacuum Wars found obstacle avoidance below average and slightly worse than the original Edge. Vacuum Wars also flags the small onboard bin, which can fill before the robot returns in a shedding home. Both found the app easy.
Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
Not reliably. Vacuum Wars had it avoid 14 of 24 obstacles, below average, and PCWorld found thin cables and flat objects hard for it, even though bowls and toys were usually spotted. Pick up cables and don't trust it near pet accidents.
Does it fit under low furniture?
Its listed height is 7.98cm with the turret lowered the specifications, and PCWorld saw it retract near low furniture. Measure the tightest gap beneath yours and leave extra room for movement. A gap just over 8cm won't necessarily be enough, particularly with low crossbars or uneven floors.
Can it cross rugs and raised thresholds between rooms?
Rugs are fine and doorway thresholds are the weak point. The mops lift 12mm over carpet, per Vacuum Wars, and PCWorld found short-pile carpet easy but suggests no-go zones for shaggy rugs and fringes. It failed a sill just over 2cm in PCWorld's home, so tall thresholds need a different robot.
Can it leave the mops in the dock for carpet?
Yes. PCWorld found it can drop the mops at the dock for a carpet-only run, and otherwise lifts them when it crosses carpet. PCWorld suggests watching the first carpet run and adjusting the settings if needed.
How often do I have to empty or refill anything?
Mostly you top up the clean-water tank and empty the dirty one, according to PCWorld, with the wash tray, brushes and filters needing an occasional clean. Roborock says a dust bag lasts up to 65 days. Detergent has to be added to the water by hand, per PCWorld.
Alternatives
Other robot vacuums to compare.
Qrevo Curv 2 Pro
Why consider it: A similarly low body and a lifting chassis for taller stepped transitions; threshold shape still matters.
The compromise: Its spinning pads smeared sticky spills in testing and it runs over small objects.
Saros 10R
Why consider it: Under 8cm with no turret at all, and one of the best robots tested at dodging clutter.
The compromise: Pet hair buried in carpet is its weak spot, which is where the Edge 2 shines.
Omni C28
Why consider it: A cheaper full-dock robot whose vacuuming and self-rinsing roller mop tested far better than its price suggests.
The compromise: It has no camera and stands 11cm tall, so it won't reach under low furniture.
