Roborock Qrevo Slim vs Roborock Qrevo Edge 3 Pro
Quick take: The Roborock Qrevo Slim costs $101 less; the Roborock Qrevo Edge 3 Pro has stronger suction (36,000 vs 11,000 Pa).
Which one to buy
Despite its name, the Qrevo Slim isn't the thinner robot here. It's listed at 3.2 in tall against the Qrevo Edge 3 Pro's 3.14 in, and at $1,399 it costs about $100 less, though it is now discontinued; Roborock's successor is the Saros 10R at $900. What the Slim has is a track record. It ranked #2 overall in independent testing, mapped a floor in about 5 minutes, placed third in obstacle avoidance, and outscored several pricier flagships at mopping, with above-average pet-hair pickup.
Owners who moved up from an older Qrevo call it a night-and-day difference and say the redesigned side brush and roller fixed their complaints. They confirm it gets under furniture that stopped their old robot. The caveats are thin history, one owner whose unit damaged itself during an unsupervised run after first mapping, and an app that can overwhelm first-timers. Its 220 ml bin is small, so heavy-shedding homes lean on the dock.
The Edge 3 Pro has the bigger listed specs: 36000 Pa, a camera plus structured light rated for 300+ object types, 212°F mop washing, and double-layer thresholds up to 3.46 in. None of that has been tested independently yet, and the Edge 2 before it shipped with weaker obstacle avoidance than its predecessor, so its claims need proving. Roborock doesn't publish its battery life or bin size.
The Slim was the safer flagship, because its strengths have been measured, but it is now discontinued. The Edge 3 Pro is the bet for a home with tall thresholds, and it gets more attractive once real-world testing confirms the numbers.
Roborock Qrevo Slim
For a buyer who wants a flagship whose cleaning and avoidance have already been tested, though it is now discontinued, with the Saros 10R as its successor.
Roborock Qrevo Edge 3 Pro
Worth a look if your home has tall double thresholds or thick rugs and you can accept unverified manufacturer figures for about $100 more.

Pros & cons
Roborock Qrevo Slim
- ✓3.2in ultra-slim body reaches under furniture that stops every full-height robot
- ✓Ranked #2 overall in independent testing, with mapping completed in about 5 minutes
- ✓Mopping scored higher than several pricier premium competitors
- ✓Above-average pet hair pickup despite the slimmed-down chassis
- ✓Multifunctional dock automates emptying, mop washing, drying, and water refilling
- ✗Small 220ml internal dustbin — needs frequent auto-empty cycles in heavy-pet-hair homes
- ✗Navigation occasionally struggled during zone cleaning after furniture was moved around
- ✗Bench-tested raw suction numbers ran below category average (though real-world cleaning didn't show the gap)
- ✗At roughly $1,400 you're paying flagship money specifically for the slim engineering
- ✗Manufacturer doesn't publish a noise level for this model
Roborock Qrevo Edge 3 Pro
- ✓36,000Pa is Roborock's highest published suction figure to date
- ✓Upgraded threshold climbing (double-layer thresholds to 3.46in) versus the Edge 2
- ✓212°F mop self-cleaning with a claimed 99.99% bacteria removal rate
- ✓300+ recognizable obstacle types using camera plus structured light plus lateral sensing
- ✓Retains the 3.14in slim profile for under-furniture cleaning
- ✗Too new for independent hands-on reviews — suction and obstacle-avoidance figures are manufacturer claims, not yet verified
- ✗Roborock's own prior Edge 2 shipped with a real obstacle-avoidance regression versus its predecessor, so this generation's real-world performance is unproven
- ✗Manufacturer doesn't publish battery life, dustbin capacity, water tank capacity, noise level, or weight
- ✗Priced above the Edge 2 for spec gains that haven't been independently confirmed yet
Roborock Qrevo Slim vs Roborock Qrevo Edge 3 Pro: common questions
Is the Roborock Qrevo Slim lower than the Qrevo Edge 3 Pro?▾
No. The Slim is listed at 3.2 in tall and the Edge 3 Pro at 3.14 in, so on paper the Edge 3 Pro clears slightly lower furniture. Slim owners do confirm it reaches under pieces their older robots couldn't.
Should I trust the Qrevo Edge 3 Pro's 36000 Pa and obstacle claims over the tested Qrevo Slim?▾
Not yet. No independent hands-on testing of the Edge 3 Pro has been published, and the Edge 2 regressed on obstacle avoidance versus its predecessor. The Slim's #2 overall ranking and third place in obstacle testing are measured results.
Which handles tall door thresholds better, the Qrevo Slim or the Qrevo Edge 3 Pro?▾
The Edge 3 Pro is rated for single thresholds up to 1.77 in and double-layer thresholds up to 3.46 in, a step up from the Edge 2. Those are manufacturer figures, but if tall transitions are your main problem, it's the one built for them.
