Key differences
- Suction: 36,000 Pa (Saros 20) vs. 30,000 Pa (Roomba Max 775 Combo) — a real gap on paper.
- Mopping approach: the Saros 20 uses spinning mop pads with a 212°F hot-water wash; the Max 775 Combo uses a self-cleaning PowerSpin roller mop with a retracting cover that lifts on carpet — different systems, not a straight upgrade/downgrade.
- The Saros 20's AdaptiLift chassis crosses double-layer thresholds up to 8.8cm (3.46in) — independent reviews call this a standout feature; iRobot doesn't publish a directly comparable threshold spec.
- Only the Saros 20 supports Apple Home via Matter; the Max 775 Combo works with Alexa, Siri and Google Assistant.
- The Max 775 Combo is iRobot's first flagship since the company emerged from Chapter 11 in January 2026 under new ownership (Picea) — a real generational leap for iRobot, but with less accumulated independent long-term review history than Roborock's more established line.
- Both offer a fully hands-free dock: self-empty, mop wash and hot-air dry.
Winner by category
Roborock Saros 20: pros
- Highest suction in the catalog (36,000 Pa)
- Best-in-class threshold crossing
- Only one with Apple Home / Matter support
- Dock washes and heat-dries the mop
iRobot Roomba Max 775 Combo: pros
- Big suction leap over iRobot's previous generation (30,000 Pa)
- 'Roomba' brand recognition — the most generic search term in the niche
- Dock washes and heat-dries the mop
- iRobot is operating normally again after completing its January 2026 restructuring
Our conclusion
Roborock's spec sheet is stronger on paper — more suction, better threshold crossing, and the only one with Apple Home support. But that's not the whole story: the Max 775 Combo is iRobot's most serious comeback in years, and its roller-mop system is a genuinely different approach some households prefer over spinning pads. If you want the highest-suction, most feature-complete flagship and you're in the Apple ecosystem, the Saros 20 is the safer pick. If you trust the Roomba name and prefer a roller mop, iRobot's newest generation is a real contender — just go in aware it has less independent long-term track record than Roborock's line.
