The investigation
5 questions this comparison examines
How much independent testing actually backs each machine?
Launch dates cluster within eight weeks of each other, but published testing does not. Each product's own evidence record shows how much is manufacturer-authored.
Roborock Qrevo 2 Pro
Plus 415 Combo
Plus 575 Combo
Plus 515 ComboVacuum Wars covered the Qrevo 2 Pro's launch, and Gizmodo and Tom's Guide each published an in-person review documenting cable pickup and a carpet-boundary miss.
The 415, 575 and 515 Combo records show launch coverage from Vacuum Wars and Reviewed restating manufacturer specifications, with no independent test results reported for any of the three SKUs.
What does each dock automate, and where does it stop?
All four pair a self-emptying dock with mop-pad washing, but the wash chemistry and the water handling are not identical across the four docks.
Roborock Qrevo 2 ProPlus 415 ComboPlus 575 ComboPlus 515 ComboiRobot's product documentation for the 575 Combo lists automatic detergent refill during the AutoWash cycle, a feature absent from the 415 and 515 Combo listings.
Vacuum Wars and Roborock's own product page both describe the Qrevo 2 Pro's dock washing pads at roughly 149°F and drying them with about 113°F warm air.
What do the published specs say about suction and coverage?
All four publish a suction figure, but runtime, coverage and weight are documented unevenly across the set.
Roborock Qrevo 2 ProPlus 415 ComboPlus 575 ComboPlus 515 ComboiRobot lists 20,000 Pa for the 415 Combo, 25,000 Pa for the 575 Combo and 22,000 Pa for the 515 Combo, the last also marketed as '3x the Plus 505.'
Roborock's product page rates the Qrevo 2 Pro at 253 minutes per charge and 20,000 Pa peak suction; iRobot has not published a per-charge runtime figure for the 415 or 575 Combo.
How do navigation and obstacle handling differ on paper?
Each robot uses a different LiDAR or obstacle-avoidance tier, and only one has a documented obstacle-handling failure from outside testing.
Roborock Qrevo 2 ProPlus 415 ComboPlus 575 ComboPlus 515 ComboiRobot's product page for the Roomba Plus 575 Combo names PrecisionVision AI alongside ClearView Pro LiDAR, a camera-assisted tier not listed for the 415 or 515 Combo.
Gizmodo's in-person review of the Qrevo 2 Pro documented the robot picking up nearly every unflattened cable it crossed during testing across several floor types.
What does the current price cover, and what remains unverified?
Current pricing ranges from $499.99 to $699.99, but sticker price does not track with how much of each record independent sources have confirmed.
Roborock Qrevo 2 ProPlus 415 ComboPlus 575 ComboPlus 515 ComboiRobot's product page lists a one-year manufacturer warranty for the Roomba Plus 515 Combo; the 415 and 575 Combo listings do not state a specific warranty term.
Current prices are drawn from each product's own Robovations record as of mid-September 2026; retail prices fluctuate and are not locked at these figures.
In closing
What the evidence shows
Patterns that emerged across the questions above.
Evidence depth does not track launch order
The oldest of the four, the 415 Combo, still carries no independent review, while the newest, the Qrevo 2 Pro, already has three documenting specific failures.
Dock automation differs on detergent, not just wash temperature
The 575 Combo's dock refills its own detergent supply, the 515 Combo requires it added by hand, and the 415 Combo's dock skips detergent chemistry entirely.
Published specs have real gaps across all four
No robot in this set publishes every core figure: the 515 Combo lacks a suction rating, and the 415 and 575 Combo both omit runtime and weight.
