What the differences mean

Smart home support

Matter brings the Roborock Saros 20 into Apple Home, SmartThings and Home Assistant on top of Alexa and Google Home. The Narwal Freo 20 Edge supports Alexa, Google Home and Siri through app shortcuts, and it documents no Matter, Apple Home or SmartThings support.

Suction power

The Roborock Saros 20 is rated at 36,000 Pa and the Narwal Freo 20 Edge at 31,000 Pa. On carpet and against heavy shedding the Roborock pulls embedded debris out with less effort, while the Narwal stays strong on hard floors.

Water tank capacity

The Narwal Freo 20 Edge lists a 4.5 L clean water tank covering up to 302 square metres per fill, against 4 L for the Roborock Saros 20. On a large hard-floor home the Narwal Freo 20 Edge gets further before a refill.

Battery life

The Narwal Freo 20 Edge is rated for 210 minutes and the Roborock Saros 20 for 200, both returning to the dock to top up and resume. The difference is small enough to matter only on a very large floor.

Body height and noise

The Roborock Saros 20 is 79.8 mm tall against 95 mm for the Narwal Freo 20 Edge, so it reaches under lower furniture. The Narwal is the quieter of the two at a rated 59 dB against 63 dB, which helps in a living space.

What owners say

Owners of both robots agree on the basics: mapping that works, suction that handles pet hair, and a dock that keeps the mop clean and dry. Narwal Freo 20 Edge owners single out the extending track mop that reaches baseboards and chair legs and the reversing side brush that clears inside corners, and they warn that the dock needs space and that Apple Home and SmartThings are not supported. Roborock Saros 20 owners highlight the suction on carpet, the quiet operation and the camera for pet checks, and warn that the mop cleaning solution does not ship in the box and that threshold climbing can be inconsistent.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
