Narwal Freo Z Ultra vs Narwal Flow 2
Quick take: The Narwal Freo Z Ultra costs $100 less; the Narwal Flow 2 has stronger suction (31,000 vs 12,000 Pa); the Narwal Flow 2 runs longer per charge (275 vs 210 min).
Which one to buy
The newer Narwal costs only $100 more here and fixes the older one's biggest weakness. Freo Z Ultra owners and testers describe weak suction that chokes on heavier debris like pistachio shells. The Narwal Flow 2 is rated at 31,000 Pa against the Z Ultra's 12,000, and owners and testers report strong embedded-sand pickup from carpet and zero hair wrap on the brush.
The Flow 2 also wins on the things the Narwal Freo Z Ultra is known for. Z Ultra owners love its dual-camera avoidance and how quiet it is; Flow 2 owners trust its dual-camera system around dog toys, shoes and cables, it avoided 20 of 24 test obstacles, and it's rated at 57 dB against 65. Its battery is rated at 275 minutes against 210, and owners say it moves through a house faster, where Z Ultra owners describe inefficient routes.
Mopping is where you'd expect a contest, and the Z Ultra's own owners settle much of it: they report roughly 3-inch unmopped strips along walls and a robot that returns to rinse after small sections, draining its clean tank before a mid-size apartment is done. The Flow 2's track mop is washed continuously as it runs. Its weak spot is dried-on stains, which testers scored well below average, though a firmware update helped.
The Flow 2 has flaws to plan for. Owners report docking and open-plan mapping bugs, a 300 ml onboard bin, and a dirty-water tank that doesn't empty itself and smells if you forget it. Z Ultra owners report warranty repairs that failed again with the same fault. Buy the Flow 2. The Z Ultra is now discontinued (Narwal's replacement is the Freo Z10 Turbo at $550) and only makes sense as leftover stock priced well below the Flow 2.
Narwal Freo Z Ultra
Now discontinued; pick the Narwal Freo Z Ultra only if it's discounted well below the Flow 2 and you have a hard-floor home where quiet running and camera avoidance are all you need.
Narwal Flow 2
The better pick for almost any home: it costs only $100 more and is far stronger on suction, longer-running, quieter on paper and better at reaching wall edges.

Narwal Freo Z Ultra vs Narwal Flow 2: common questions
Is the Flow 2's obstacle avoidance as good as the Freo Z Ultra's?▾
Owners suggest it's at least as good. Both use dual cameras; Flow 2 owners trust it around dog toys, shoes and cables, and it avoided 20 of 24 obstacles in testing. Z Ultra owners say it reliably dodges socks, slippers and cords on bare floors.
Does the Flow 2 use less water than the Freo Z Ultra?▾
Its owners don't describe the Z Ultra's problem of refilling before a mid-size apartment is finished. You do still have to empty the Flow 2's dirty-water tank by hand, and owners warn it smells if left for a week.
Which handles pet hair on carpet better?▾
The Flow 2. Owners and testers report zero hair tangles and strong carpet pickup. Z Ultra owners say its anti-tangle brush handles long hair well, but its weak suction makes it a poor choice for carpet-heavy homes.
