The Budget Workhorse vs. The Premium Quiet Cleaner
The Lefant M3 MAX is the bargain pick: massive suction, longer runtime, and rotating mops at less than half the price of the Qrevo S Pro. The Roborock is quieter, more polished, and handles pet hair with less fuss, but you're paying double for the privilege. Pick the Lefant if you want raw power and don't mind baby-sitting around stairs; pick the Roborock if you want something that plays nice with your home and your ears.
Suction powerThe M3 MAX edges ahead with 20,000 Pa versus 18,500 Pa, giving you a bit more muscle for stubborn debris and pet hair.

Raw Power vs. Refinement: The Trade-Off
On paper, the Lefant M3 MAX looks like the no-brainer: 20,000 Pa of suction versus the Qrevo's 18,500 Pa, a bigger dust bin (3.2L vs 2.7L), and a runtime that stretches to 210 minutes. Throw in a price tag less than half the Roborock's, and you've got yourself a deal that makes your wallet smile. Customers report it handles pet hair effectively and cleans with real oomph, even on thick carpets.
But here's where the Roborock earns its premium: it operates at a civilized 55 dB (the M3 MAX's noise level isn't listed, and users suggest it's louder), and its all-rubber main brush was designed specifically to wrestle with pet hair without turning into a tangled mess. The Qrevo's anti-tangle system means less time fishing hair out of the brush and more time actually enjoying a clean home. It's the difference between a tool that works and a tool that works and doesn't nag you about maintenance.
Where They Stumble (And Why It Matters)
The M3 MAX's Achilles heel is navigation smarts. It maps your home with a 360-degree laser, which is solid, but it can't create no-go zones or restrict cleaning to specific rooms without physical barriers. Worse, customers report it has fallen down stairs without hesitation, which is a pretty serious design oversight in a robot you're supposed to trust. The Roborock uses AI SmartPlan 2.0 to learn your home layout and obstacles, and it won't take a nosedive into the basement.
On the mopping front, the M3 MAX's rotating mops work, but the Roborock cleans its mops at 75°C (versus the M3's 45°C) and has smarter carpet detection. Neither is a replacement for a real mop, but the Qrevo comes closer to actually cleaning rather than just dampening your floors. For pet owners especially, this matters when Fido tracks mud across the kitchen.
The Verdict: Savings vs. Sanity
If you've got the space to clear obstacles, don't mind checking on the robot occasionally, and want maximum suction and runtime for minimum spend, the Lefant M3 MAX is a solid choice. That 73% discount is real money in your pocket, and the raw performance is there. Just treat it like the tool it is: keep the stairs gated, clear the floor before it runs, and don't expect it to outsmart your home.
The Roborock Qrevo S Pro is for people who want a vacuum that handles itself without constant supervision. It's quieter, smarter about obstacles, and the anti-tangle system alone is worth the extra euros if you've got shedding pets. You're paying for refinement and peace of mind, not just suction numbers. Both will clean your floors; the M3 MAX does it on a budget, and the Qrevo does it with grace.
