NARWAL Flow 2 vs Roborock Qrevo Curv 2 Flow Canada

The NARWAL Flow 2 wins for homes that need serious mopping, its 212°F FlowWash system, 7,000 mAh battery, and VLM obstacle recognition justify the $1,999.99 CAD ask over the Qrevo Curv 2 Flow, which impresses on vacuuming but disappoints on dried-stain mopping and covers less floor per charge.

What you pay

The NARWAL Flow 2 is $1,999.99 CAD on amazon.ca. The roborock Qrevo Curv 2 Flow's Canadian price hasn't been publicly confirmed on amazon.ca, the listing exists, but a firm CAD sticker price isn't available at time of writing. The gap could be meaningful or modest, and checking the current listing directly is the only reliable way to know.

Suction and vacuuming

The Flow 2 runs 31,000 Pa; the Qrevo Curv 2 Flow runs 20,000 Pa. In independent carpet deep-clean testing, the Qrevo Curv 2 Flow hit 87% debris removal, above the 76.7% category average, despite its lower Pa figure. The Flow 2 hasn't published an equivalent standardized carpet score, but reviewers across multiple outlets report strong pet hair and embedded debris pickup. Raw Pa numbers routinely overstate real-world differences; what the Flow 2 has is a bigger gap on paper, but both machines clean carpets effectively.

Mopping performance

This is where the two machines genuinely diverge, and neither comes out looking perfect. The Flow 2 uses a 16-nozzle FlowWash rolling track mop with 212°F hot water and a continuous scraper, Vacuum Wars found its lab mopping scores lower than expected, though real-world results improved after a firmware update. The Qrevo Curv 2 Flow uses SpiraFlow with 8 hydration points, 15N downward pressure, and 220 RPM rotation, and Vacuum Wars called its mopping on dried stains "dramatically below average." Neither roller mop is a deep-stain weapon yet; the Flow 2's hotter water (212°F vs. 75°C dock wash on the Roborock) and real-time reverse-clean cycle give it the edge for stubborn messes.

Battery and coverage

The Qrevo Curv 2 Flow runs on a 5,200 mAh battery, covering around 1,286 sq ft per charge in independent testing, slightly above the category average but below many flagship rivals. The Flow 2 packs a 7,000 mAh battery, a meaningful step up. For larger Canadian homes with open-plan main floors, this difference becomes concrete: the Flow 2 is less likely to need a mid-run recharge on a 1,500 sq ft floor.

Build and design

Both robots sit at 95 mm tall, so under-furniture clearance is a draw. The Flow 2's EdgeReach mop extends to within 5 mm of walls; the Qrevo Curv 2 Flow's edge-adaptive roller reaches within 10 mm. The Flow 2's base station includes auto self-refilling and drainage; the Qrevo Curv 2 Flow's dock handles auto-refill but has a 100 ml onboard wastewater tank, too small for liquid spills above 50 ml, per Roborock's own documentation. The Flow 2 carries a 2.4 L dust bag; the Qrevo Curv 2 Flow uses a 2.5 L dock bag.

AI and navigation

Both robots claim 200-plus object recognition. The Flow 2 runs a Visual Language Model with dual 1080p cameras and a 10-TOPS processor, Vacuum Wars describes it as offering theoretically unlimited object recognition. The Qrevo Curv 2 Flow uses structured light and an RGB camera with Reactive AI; in standardized testing it avoided 16 of 24 objects, right at the category average of 16.6. Navigation speed is a Roborock strength: the Qrevo Curv 2 Flow scored 0.83 m²/min versus the 0.72 m²/min average. The Flow 2's VLM system is newer hardware, but the Roborock's LiDAR routing is fast and well-proven.

Common questions

Which is cheaper, NARWAL Flow 2 Robot Vacuum and Mop Combo or roborock Qrevo Curv 2 Flow Robot Vacuum and?

The NARWAL Flow 2 is confirmed at $1,999.99 CAD on amazon.ca; the roborock Qrevo Curv 2 Flow does not have a publicly confirmed CAD price on amazon.ca at time of writing, so a direct dollar comparison isn't possible — check the listing for the current figure.

Is NARWAL Flow 2 Robot Vacuum and Mop Combo better than roborock Qrevo Curv 2 Flow Robot Vacuum and?

For most Canadian buyers who prioritise mopping quality and larger floor coverage, yes — the Flow 2's 212°F FlowWash system, 7,000 mAh battery, and 31,000 Pa suction outperform the Qrevo Curv 2 Flow on the dimensions that matter most in this category, though the Roborock navigates faster and may come in at a lower price.

What's the biggest difference between them?

Battery capacity is the starkest gap: the NARWAL Flow 2 carries a 7,000 mAh battery versus the Qrevo Curv 2 Flow's 5,200 mAh, which translates to meaningfully more floor coverage per charge in independent testing (~1,286 sq ft for the Roborock versus a larger estimated range for the Narwal).
