What the differences mean
Suction power
22,000Pa against 13,000Pa. The Narwal Flow has the larger reserve for embedded dirt and pet hair, while the iRobot Roomba 705X leans on Automatic Carpet Boost to compensate on rugs.
Battery life
200 minutes against 120 on the spec sheet. The Narwal Flow can cover a large home in one outing, and the iRobot Roomba 705X will return to recharge partway through a floor more often.
Mop system
The Narwal Flow uses a rolling track mop rinsed continuously with 113F water and scraped as it scrubs, so the surface touching the floor stays clean. The iRobot Roomba 705X uses a PowerSpin roller that turns at 200 RPM and relies on the dock for its heated wash.
Dock capacity
The Narwal Flow dock holds a 2.5L bag rated for around 120 days and a 5L clean water tank. The iRobot Roomba 705X AutoWash dock empties for up to 75 days and doses solution automatically, but its water and bin figures are not published.
Height
The Narwal Flow is 95 mm tall and the iRobot Roomba 705X 105 mm. The difference decides which low sofas and bed frames each robot can clean under, so check your clearance before choosing.
Which one to buy if
- your home has a lot of hard floor to mop
The Narwal Flow track mop rinses itself with hot water while scrubbing, so a kitchen floor is washed rather than wiped with a dirty pad.
- you need the robot to cover a large floor in one charge
The Narwal Flow is rated at 200 minutes against 120 on the iRobot Roomba 705X, so it finishes bigger jobs before it has to dock.
- your priority is the strongest suction of the pair
At 22,000Pa the Narwal Flow out-pulls the 13,000Pa motor of the iRobot Roomba 705X, which matters most on carpet and with heavy shedding.
- you want a lower-priced self-maintaining combo
The iRobot Roomba 705X is the more affordable of the two and still empties, washes and dries its mop on its own.

What owners say
Narwal Flow owners keep returning to the mopping. They describe the FlowWash track as the first system that washes the floor instead of pushing dirty water around, with dried mud and kitchen grease lifting in a pass or two thanks to the hot water and constant downward pressure, and several say the dirty water tank makes the difference visible. Suction gets nearly the same praise, with owners reporting the 22,000Pa motor ramping up on dirtier patches and a tangle-free roller that ends manual hair removal. Quiet running, fast dToF LiDAR mapping, Matter support and a dock that empties for months all come up. The recurring warning is carpet: the app mislabels bare floor as rug and some owners report poor pickup on certain pile types, while corners still fall short even with the extending mop.

Frequently Asked Questions
Which is better overall: iRobot Roomba 705X or Narwal Flow?
The Narwal Flow, on a wider margin of suction and battery. It is rated at 22,000Pa and 200 minutes against 13,000Pa and 120 minutes on the iRobot Roomba 705X, and its self-rinsing track mop is the more convincing mopping system.
What is the biggest difference between the iRobot Roomba 705X and the Narwal Flow?
The mop and the run time. The Narwal Flow rinses its rolling track mop with hot water continuously and runs for 200 minutes, while the iRobot Roomba 705X spins a roller pad and runs for 120 minutes before recharging.
Do the iRobot Roomba 705X and Narwal Flow work with Apple Home?
Yes, both the iRobot Roomba 705X and the Narwal Flow support Matter, which brings them into Apple Home, SmartThings and Home Assistant, and both also work with Alexa and Google Home.
Is the Narwal Flow good on carpet?
It is rated for it, with CarpetFocus sealing the brush and the mop lifting 12 mm, but this is where owner reports diverge. Some are happy with area rugs, while others describe poor pickup on certain pile types and an app that keeps detecting carpet where there is none.
Who should buy the iRobot Roomba 705X?
Buyers who want Matter and Apple Home support with a fully self-maintaining AutoWash dock and automatic solution dosing, and who are happy with a shorter run and a smaller suction reserve at a lower price.
Who should buy the Narwal Flow?
Homes with mostly hard floor that want mopping done properly, plus the strongest suction and longest battery of this pair, and a dock that washes, dries and empties for months.
