What the differences mean
Rated suction
The Roborock Saros 20 Flow is rated at 36000Pa and the Narwal Flow at 22000Pa, so the Roborock has the bigger number for deep carpet and heavy debris. The Narwal Flow leans on its roller mop and real-time rinsing rather than raw vacuum force.
Wi-Fi bands and Bluetooth
The Narwal Flow connects on 2.4 GHz and 5 GHz and pairs over Bluetooth first. The Roborock Saros 20 Flow is a 2.4 GHz only machine by comparison, which matters on a router that does not separate its bands during setup.
Detergent handling
The Roborock Saros 20 Flow doses cleaning solution from the dock automatically. On the Narwal Flow the solution is measured into the clean water tank by hand, with no separate dosing reservoir, so refilling is a small manual step.
Body height
The Narwal Flow stands 95 mm tall and the Roborock Saros 20 Flow 89.8 mm, so the Roborock slips under slightly lower furniture. Both are low enough for most beds and sofas.
Which one to buy if
- your home is mostly hardwood, tile or laminate
The Narwal Flow was built around the FlowWash roller mop, which is the reason owners bring it home.
- you want the highest rated suction for carpets
The Roborock Saros 20 Flow is rated at 36000Pa against the Narwal Flow's 22000Pa.
- your router runs one combined dual-band network
The Narwal Flow supports 5 GHz and Bluetooth pairing, while the Roborock Saros 20 Flow is 2.4 GHz only.
- you would rather not measure detergent by hand
The Roborock Saros 20 Flow doses cleaning solution from the dock on its own.
- you want the lowest body for tight furniture
At 89.8 mm the Roborock Saros 20 Flow is the slimmer of the two by a small margin.

What owners say
Owners of the Narwal Flow keep returning to the same point: the rolling track mop washes the floor instead of pushing dirty water around, and dried spills that used to need a hand mop come up in a pass or two. Pet households credit the anti-tangle roller with ending manual hair removal, and quiet running, long runtime and fast dToF mapping with camera avoidance earn consistent praise. The recurring complaint is carpet: some owners say the app mislabels bare floor as rug and cannot be corrected by hand, while others describe poor pickup on certain pile types. A few also note that stairs need blocking off during the first mapping run and that detergent is measured into the tank by hand.
