Narwal Flow 2 vs Roomba Max 775 Combo at a Glance

The Narwal Flow 2 carries a published 31,000 pascal (Pa) suction rating and has independent test results behind it. The Roomba Max 775 Combo lists at $999.99, below every Flow 2 price in The Bot Scout's review. iRobot publishes no Pa figure for the Max 775 Combo at all.

Detection hardware differs too. The Flow 2 pairs an embedded low-profile LiDAR (light detection and ranging) sensor with dual 1080p RGB (red, green and blue) cameras and a vision language model. The Max 775 Combo uses ClearView Pro LiDAR for mapping and PrecisionVision AI (artificial intelligence) to avoid cords, shoes and pet waste.

Both docks wash the mop, dry it with warm air and empty the robot's dustbin into a bag. iRobot publishes single figures for the Roomba dock: 165°F wash water, 122°F drying air and a bag rated for 3 months. Narwal's dock runs an AI-adaptive wash between 113°F and 176°F, then dries at 104°F.

Where Narwal Wins

The Narwal Flow 2 wins on measured evidence, because independent testing has put numbers on its obstacle avoidance, carpet pickup and brush roll. Narwal also publishes its 31,000 Pa rating, which no independent lab has measured. CarpetFocus technology aims to hold that suction as the robot moves from hard floor onto carpet.

In independent testing, the Flow 2 avoided 20 of 24 planted obstacles, against a category average of 16. Independent coverage reports that it flags items down to about 5 mm. That gives you a reported figure to weigh against Narwal's marketing claim of effectively unlimited recognition.

On carpet, the Flow 2 picked up 88% of flattened pet hair and 84% of embedded sand. Its brush roll showed zero tangling, against a 26% average tangle rate across tested robots. Over a three-month home test, the robot needed two manual interventions.

Bag changes come less often on the Flow 2. Its dock empties into a 2.5-liter disposable bag rated for up to 120 days. Counting a month as 30 days, iRobot's 3-month rating equals about 90 days, so Narwal's rating runs about 30 days longer.

Where Roomba Wins

The Roomba Max 775 Combo wins on listed price, at $999.99 from iRobot. iRobot shows it in stock on its United States site. The cheapest Flow 2 price in The Bot Scout's review was a $1,099.99 pre-order offer that ran only from April 13 to April 28, 2026.

iRobot publishes fixed temperatures for the AutoWash dock: 165°F (75°C) wash water and 122°F (50°C) drying air. That drying air is 18°F warmer than the Flow 2 dock's 104°F setting. The dock also dispenses StayClean concentrate automatically.

The Roomba dust bag adds carbon odor control and holds debris for up to 3 months. iRobot also lists the dock's size as 17.7 by 16.7 by 17 inches, with a weight of 18.96 lb. Measure the floor space for the dock against those figures before ordering, since the Flow 2 review lists no dock dimensions.

ClearView Pro LiDAR saves up to 5 maps, and the Max 775 Combo runs on a 6000 mAh LFP battery. The Flow 2 review on this site lists neither a map count nor a battery figure. Neither review states a runtime.

Mopping Systems Compared

The Flow 2 mops with a flat track belt, while the Max 775 Combo mops with a spinning roller.

Narwal's FlowWash system is a self-rinsing flat-loop belt pressed down at 7 to 12 newtons. A 16-nozzle rinse system cleans the belt, and an EdgeReach extension reaches baseboard edges. Over carpet, the mop lifts 12 mm automatically.

iRobot's PowerSpin roller mop spins at 200 RPM and adds SmartScrub back-and-forth movement. Heated spot mopping and PerfectEdge for edges complete the system. On carpet, the roller cover lifts and shields the mop.

Only the Flow 2 has mopping test results in The Bot Scout's reviews. Out of the box, it scored 67.5 on dried stains and 34 on coffee stains in lab testing, under category averages of 108 and 94. After a firmware update, the three-month home test called its mopping the cleanest the reviewer had seen.

Install the latest Flow 2 firmware before the first mop job, since the better results came after an update. Read the full mopping notes in the Narwal Flow 2 review.

The Price Gap Is Not Fixed

The Flow 2 has appeared at three prices, while the Max 775 Combo has one listed price in The Bot Scout's review. Narwal set the Flow 2 MSRP at $1,499.99.

During Narwal's April 2026 pre-order window, from April 13 to April 28, the Flow 2 sold for a promotional $1,099.99. That was $400 under the $1,499.99 MSRP. At review time, Narwal's own store listed it at $1,299.99.

iRobot lists the Max 775 Combo at $999.99 at the time of writing. iRobot has published no official launch date for it.

Because both prices move, open the Narwal Flow 2 product page and the Roomba Max 775 Combo product page on the same day before you buy. For price ranges beyond these two robots, see the robot vacuum price guide.

Who Should Skip Narwal or Roomba

Skip the Roomba Max 775 Combo if you need a suction figure in pascals, because iRobot publishes none for it. Its only suction claim is relative: 4X more power-lifting suction. With no shared standard between makers, compare the Flow 2's 31,000 Pa only against other robots that publish a Pa rating.

Skip the Max 775 Combo too if you want independent test results before you spend $999.99. The Bot Scout's Roomba Max 775 Combo review has no obstacle, pet-hair or mopping test figures. To compare other options, see the Roomba alternatives guide.

Skip the Flow 2 if a polished app matters most to you, because testers described its app as unintuitive. Read the app notes in the Flow 2 review before ordering.

If you buy the Flow 2, do not rely on Valuables Protection to guard loose items. It keeps at least 5 cm from recognized items such as keys and wallets, but testers found that mapping inconsistent. Pick keys and wallets up off the floor before each run.

Skip both robots if your budget stops below $999.99, the lower of the two listed prices. See the robot vacuum price guide.

Narwal vs Roomba: The Verdict

Buy the Narwal Flow 2 if you want published suction and independent test results. It avoided 20 of 24 planted obstacles, picked up 88% of flattened pet hair and showed zero brush-roll tangling. Accept two tradeoffs: a higher price than the Max 775 Combo at every figure in the review, and an app testers called unintuitive.

Buy the Roomba Max 775 Combo if the $999.99 listed price matters most. Its dock publishes fixed wash and dry temperatures, uses a carbon odor-control bag and lists its exact size. Accept that iRobot gives no Pa rating and that The Bot Scout's review has no independent test figures for it.

This verdict would change if iRobot published a Pa rating for the Max 775 Combo. It would also change if independent obstacle, pet-hair or mopping results landed for the Roomba. Until then, choose by whether measured results or the lower listed price matters more to you.

Bottom Line

Settle Narwal vs Roomba by deciding whether measured test results or the lower listed price matters more to you. Then confirm both prices on the same day on the Narwal Flow 2 product page and the Roomba Max 775 Combo product page. If neither robot fits, compare more models in the best robot vacuum guide.

Choose the Narwal Flow 2 for published suction and independent test data, or the Roomba Max 775 Combo for the lower listed price.

FAQs

Is Narwal or Roomba better?

Neither is better on every count. The Narwal Flow 2 publishes a 31,000 Pa suction rating and has independent results for obstacles, pet hair and tangling. The Roomba Max 775 Combo lists lower at $999.99 and publishes fixed dock temperatures, but has no Pa rating or independent test figures in The Bot Scout's review. Pick the Flow 2 for measured results and the Max 775 Combo for price.

Which is cheaper, Narwal or Roomba?

The Roomba Max 775 Combo is cheaper at its $999.99 listed price. The Narwal Flow 2 carries a $1,499.99 MSRP and was listed at $1,299.99 on Narwal's store at review time. Its April 13 to April 28, 2026 pre-order price was $1,099.99. Confirm current prices on the Flow 2 product page and the Max 775 Combo product page.

Which has stronger suction, Narwal or Roomba?

Published numbers cannot settle it. Narwal rates the Flow 2 at 31,000 Pa, and no independent lab has measured that figure. iRobot publishes no Pa rating for the Max 775 Combo, only a claim of 4X more power-lifting suction. Manufacturer ratings do not share one standard, so the two cannot be ranked on suction.

Which is better for pet hair, Narwal or Roomba?

The Narwal Flow 2 has the stronger evidence for pet hair. In independent testing, it picked up 88% of flattened pet hair from carpet and showed zero brush-roll tangling against a 26% average. The Bot Scout's Roomba Max 775 Combo review has no pet-hair test figures, so the Roomba's pet-hair pickup is unmeasured there.

How does Narwal vs iRobot mopping compare?

The two robots use different mop hardware. The Flow 2 uses a FlowWash flat-loop belt pressed at 7 to 12 newtons that lifts 12 mm over carpet. The Max 775 Combo uses a PowerSpin roller at 200 RPM with SmartScrub movement and heated spot mopping. Only the Flow 2 has test results, and its mopping earned the cleanest verdict in a three-month home test after a firmware update.

How long does each dock bag last?

The Narwal Flow 2 dock bag is rated for up to 120 days, and the Roomba Max 775 Combo bag for up to 3 months. Narwal uses a 2.5-liter disposable bag. iRobot's bag adds carbon odor control.

What does the Roomba Max 775 Combo cost?

iRobot lists the Roomba Max 775 Combo at $999.99 at the time of writing. It shows as in stock on iRobot's United States site, and iRobot has not published an official launch date. Confirm today's price on the Roomba Max 775 Combo product page.

Does Roomba publish a suction rating for the Max 775 Combo?

No, iRobot publishes no Pa rating for the Max 775 Combo. Its only suction claim is 4X more power-lifting suction, which is a relative figure. That leaves no number to set against the Narwal Flow 2's 31,000 Pa rating.
