Roborock Qrevo S Pro vs Qrevo 2 Pro: Which Should You Buy?

The Qrevo S Pro and Qrevo 2 Pro sit close together in Roborock's lineup, and on paper they look similar: LiDAR navigation, dual spinning mop pads, and a multifunction dock that washes, dries, and empties. The difference is what they prioritize — the Qrevo 2 Pro pushes raw suction and carpet features, while the Qrevo S Pro is the value play with the same core convenience.

Here's how they break down. (Specs vary slightly by region — check Roborock's official page for your market before buying.)

Where the Qrevo 2 Pro wins

Carpets. This is the single biggest reason to pay more. The 2 Pro adds a 15mm mop lift (versus 10mm), a Carpet Boost mode with a double-pass deep clean, and — the headline trick — it can leave its mop pads at the dock entirely for vacuum-only runs, so carpets never touch a damp pad. If your home is carpet-heavy, these features matter every single run.

Pet hair. The DuoDivide main brush is Roborock's anti-tangle design, and the reversible side brush handles corners better. In homes with long-haired pets or long-haired humans, the 2 Pro will need less brush maintenance.

Edge coverage. The FlexiArm extends the mop pad outward to reach along walls and into corners — the S Pro leaves a slightly wider unmopped strip at edges.

Longer runtime and bigger dock tanks suit very large homes where the S Pro might need a mid-clean refill.

Where the Qrevo S Pro wins

Price — often by a wide margin. The Qrevo 2 Pro launched around $599–$799 depending on region and has settled since; the S Pro typically undercuts it significantly while keeping the dock features that matter most (hot-water washing, heated drying, self-emptying, auto-refill). If both are discounted, compare the actual gap — the S Pro's savings can cover several years of replacement parts.

Hard-floor mopping is effectively equal. Both use 200 RPM dual spinning pads with hot-water washing between runs. For homes that are mostly tile, laminate, or wood, the 2 Pro's carpet advantages simply never come into play.

Running costs: the hidden difference

Both robots wear through the same categories of consumables — roller brush, side brushes, filters, mop pads, dust bags — and both are far cheaper to maintain with quality aftermarket parts than with original-brand consumables. For the S Pro, a full yearly refresh is $29.99 via the Qrevo S Pro Accessory Kit, and every individual part is $6.99–$15.99 (see the complete accessory guide).

Both also mop better with a proper cleaning solution than with plain water. The EcoCleanPath Cleaning Solution ($15.99 per 1L bottle, lasting months) is formulated for robot mopping systems and fits every Roborock model, so the same bottle serves either robot.

Whichever robot you buy, budget for this: a robot vacuum with worn brushes and clogged filters cleans like a $200 machine regardless of its headline Pa rating.

Verdict

Choose the Qrevo 2 Pro if carpets make up a third or more of your floor space, you have shedding pets, or you want maximum edge coverage — its carpet and anti-tangle features are real, daily-use advantages.

Choose the Qrevo S Pro if your home is mostly hard floors. You get the same mopping quality and dock convenience for meaningfully less money, and the savings will keep it supplied with fresh parts for years.

Either way, the dock does the daily chores — your job is just the monthly glance at brushes, filters, and bags.

Frequently asked questions

Do the Qrevo S Pro and Qrevo 2 Pro use the same replacement parts? No — Roborock revises consumable designs between models, and parts are not reliably interchangeable. Always match parts to your exact model.

Which is better for pet owners? The Qrevo 2 Pro, mainly because of the anti-tangle DuoDivide brush. The S Pro handles pet hair fine but needs the roller cleaned more often.

Is the Qrevo S Pro's lower suction a problem? In practice, no — for hard floors. Raw Pa matters most on carpet, which is exactly where the 2 Pro's other advantages (mop lift, deep-clean mode) also come into play.
