Quick Answer: Narwal and eufy are both premium, mopping-focused robot-vacuum brands, but they win on different things in 2026. Narwal’s Flow 2 Ultra flagship currently costs $1,099.99 (down from $1,499.99 list) and posted 20/24 obstacle avoidance plus a near-streak-free mop finish in independent Vacuum Wars testing. eufy’s Omni S2 flagship costs more at $1,599.99 MSRP but packs a more feature-rich 12-in-1 dock — hot-water mop sterilization and a fragrance diffuser — though Tom’s Guide and T3 both flagged its navigation as its one real weak spot. Buy Narwal for price-to-performance at the top end; buy eufy for the most automated dock and a broader lineup.
Narwal and eufy both built their reputations on self-washing mop docks rather than raw suction alone, which makes them an unusually close matchup — closer than either brand is to Roborock or Roomba. We pulled the independently tested specs from both brands’ current 2026 flagships and budget lines to see where they actually differ.
Quick verdict
- Buy Narwal if you want the most price-to-performance at the flagship level — the Flow 2 Ultra currently undercuts eufy’s flagship on price while posting better lab-tested obstacle avoidance and a near-streak-free mop finish.
- Buy eufy if you want the most automated dock — the Omni S2’s 12-in-1 station handles hot-water mop sterilization and even scents the room, and eufy’s lineup spans further down to true budget models.
Narwal vs eufy by the numbers
- 31,000 Pa vs 30,000 Pa: Narwal’s Flow 2 Ultra claims 31,000 Pa (per Narwal) against the eufy Omni S2’s 30,000 Pa via its AeroTurbo 2.0 motor (per T3 and Tom’s Guide) — a virtual tie on paper, and Vacuum Wars independently measured the Flow 2 Ultra at nearly double the category-average sealed suction.
- $1,099.99 vs $1,599.99: The Narwal Flow 2 Ultra’s current price is $500 less than the eufy Omni S2’s $1,599.99 launch MSRP, though eufy wins back the budget tier — its RoboVac 11S Max routinely sells for $139.99-$159.99 versus Narwal’s cheapest model at around $399.
- 20/24 obstacle avoidance: Vacuum Wars measured the Flow 2 Ultra avoiding 20 of 24 test obstacles against a 16-average field, while two independent reviewers (Tom’s Guide, T3) both flagged the Omni S2’s navigation as its weakest area despite newer camera hardware.

Suction and carpet
Both brands claim numbers in the same league at the top of their lineups. Narwal rates the Flow 2 Ultra at 31,000 Pa (per Narwal), and Vacuum Wars independently measured 1.92 kPa of sealed suction against a 0.99 kPa category average — nearly double — which translated to 84% embedded-sand carpet removal in the same test suite. eufy’s Omni S2 claims 30,000 Pa via its new AeroTurbo 2.0 motor (per T3 and Tom’s Guide), nearly 4x its predecessor’s 8,000 Pa, and eufy’s own comparative testing found 87% embedded-sand removal versus 61% for the older S1 Pro. On raw numbers it’s essentially a tie between the two current flagships — see our best robot vacuum for carpet guide for how both brands rank against Roborock and Dreame.
Mopping
Both brands lead with mopping, but the mechanics differ. Narwal’s Flow 2 Ultra uses a continuously-rinsed rolling track mop, re-wetted with AI-adaptive hot water (113-176°F, per Narwal) as it turns — Vacuum Wars measured just 0.25 grams of water residue left behind, a near-streak-free result, though its dried-stain and coffee-stain scores landed below the category average despite the marketing. eufy’s Omni S2 uses HydroJet 2.0, a self-cleaning rotating dual-brush roller applying about 15N of downward pressure at up to 240 RPM (per Vacuum Wars), and lifts roughly 2 inches to avoid soaking carpet as it crosses. Both self-wash and dry the mop at the dock. For finish quality Narwal has a slight edge; for scrubbing pressure eufy’s roller design pushes harder. See our best mopping robot vacuum guide for the full field.
Navigation and obstacle avoidance
This is where the two brands’ independent test results diverge most. Narwal’s Flow 2 Ultra uses TwinAI, a Visual Language Model paired with dual HD cameras and a 10-TOPS AI processor, and Vacuum Wars had it avoid 20 of 24 test obstacles against a 16-average field. eufy’s Omni S2 runs a newer CleanMind AI system that combines 3D mapping with RGB camera vision and can recognize over 200 object types (per Android Authority) — a genuine upgrade over the S1 Pro’s older infrared system — but both Tom’s Guide and T3 independently flagged navigation as the Omni S2’s weakest area relative to top rivals. The two brands weren’t tested on the same course by the same lab, so this isn’t a controlled head-to-head, but the pattern across independent reviewers currently favors Narwal here.
Dock and automation
eufy pulls ahead on dock features. The Omni S2’s station is a 12-in-1 design: self-empty, mop wash, mop dry, water refill, electrolyzed hot-water sterilization of the mop, and a built-in fragrance diffuser — eufy rates the dustbin to go roughly 68 days between manual empties. The Flow 2 Ultra’s dock covers the core loop — self-empty, mop wash, hot-water refill — into a 2.5L dust bag rated for up to 120 days maintenance-free, which stretches longer between bag changes but skips eufy’s sterilization and scenting extras. If dock automation is the deciding factor, eufy currently does more; if you just want the longest stretch between bag changes, Narwal’s dock lasts longer.
Price and value
At the flagship tier Narwal is currently the better deal: the Flow 2 Ultra sells for $1,099.99, down $400 from its $1,499.99 list price per Narwal’s own US store, versus the eufy Omni S2’s $1,599.99 launch MSRP — a $500 gap for two flagships with comparable claimed suction. At the budget end eufy wins back ground: the RoboVac 11S Max lists at $279.99 but frequently sells for $139.99-$159.99, well under Narwal’s cheapest model, the Freo Pro at around $399. In the mid-range, eufy’s X10 Pro Omni (8,000 Pa, self-washing twin mop pads) typically runs around $800 per our own testing, while Narwal’s current mid-tier, the Freo Z10 Turbo ($659.99, 25,000 Pa), undercuts it on price while claiming triple the suction. Whichever tier you’re shopping, both brands appear in our best budget robot vacuum and best self-emptying robot vacuum guides.
The bottom line
For most buyers chasing the best flagship for the money in 2026, Narwal’s Flow 2 Ultra is the sharper buy right now — cheaper than eufy’s flagship, with better independently tested obstacle avoidance and a near-streak-free mop finish. eufy’s Omni S2 is still worth its higher price if dock automation is what you actually want day to day, and eufy’s lineup reaches further down into true budget territory than Narwal’s does.
