It supports Matter, so it reaches Apple Home and SmartThings on top of Alexa, Google Home and Home Assistant, and it is the only one of the pair with 5 GHz Wi-Fi. It also carries the higher rated suction, 36,000 Pa against 31,000 Pa, and the bigger dock dust capacity, 2.7 L against 2.5 L. The Narwal Freo 20 Edge answers with a lower price, a longer 210 minute battery rating and a larger 4.5 L clean-water tank, and it is the quieter of the two at its rated level. Choose the Roborock Saros 20 Sonic for a multi-platform home or a carpet-heavy floor, and the Narwal Freo 20 Edge for the longest mopping runs and the lower outlay.

What the differences mean

Suction power

The Roborock Saros 20 Sonic is rated at 36,000 Pa against 31,000 Pa for the Narwal Freo 20 Edge. Both figures are the manufacturers' own laboratory numbers, so treat the gap as something you may notice on carpet and heavy debris rather than on everyday dust.

Smart home support

The Roborock Saros 20 Sonic works with Apple Home, SmartThings, Home Assistant and Matter on top of Alexa and Google Home. The Narwal Freo 20 Edge stops at Alexa, Google Home and Siri, with no Apple Home, SmartThings or Matter path.

Wi-Fi bands

Dual-band is the practical difference here. The Roborock Saros 20 Sonic joins either 2.4 GHz or 5 GHz and adds Bluetooth, while the Narwal Freo 20 Edge is 2.4 GHz only, which can trouble setup on a router that hides the 2.4 GHz band behind one combined network name.

Battery and water capacity

The Narwal Freo 20 Edge is rated for 210 minutes and carries a 4.5 L clean-water tank, both ahead of the 190 minutes and 4 L of the Roborock Saros 20 Sonic, so the smaller robot can mop longer between refills.

What owners say

Narwal Freo 20 Edge owners keep returning to two themes: how well the track mop reaches edges and corners, and how little hair ends up wrapped around the brush. Several describe the reversing side brush sweeping dust out of inside corners, and the rear LiDAR mapping a floor in a few minutes while the structured-light sensor steers around cables and shoes. The app draws praise for per-room schedules, no-go zones and carpet labelling. The complaints are consistent too: the 2.4 GHz-only Wi-Fi can be awkward on a network that hides that band, the dock is large and needs clearance on both sides, almost everything runs through the app, and the first configuration pass takes a while.
