It doubles the suction at 36000Pa against 18000Pa, runs up to 200 minutes against 150, stands just 79.8 mm tall and adds 5 GHz Wi-Fi plus Apple HomeKit, SmartThings and Matter support. The Narwal Freo Z10 Ultra is the more affordable of the pair and owners rate it highly for how quiet it is, for camera-based avoidance that steers clear of pet accidents and for an EdgeReach mop that swings into corners. Both map with LiDAR, wash and dry their mops with hot water and empty their own dust. Pick the Roborock Saros 20 for raw power and the widest platform support, and the Narwal Freo Z10 Ultra for a quiet, pet-aware mopper on hard floors.

What the differences mean

Suction

36000Pa on the Roborock Saros 20 against 18000Pa on the Narwal Freo Z10 Ultra. On hard floors both do well; the Roborock has the headroom for rugs and hair packed into gaps.

Height

The Roborock Saros 20 stands 79.8 mm tall and the Narwal Freo Z10 Ultra 109.6 mm, so only the Roborock slides under many low sofas and bed frames.

Runtime

Up to 200 minutes on the Roborock Saros 20 against 150 on the Narwal Freo Z10 Ultra. In a large home the Narwal is more likely to stop and recharge before it finishes.

Smart home and Wi-Fi

The Roborock Saros 20 works with Alexa, Google Home, Apple HomeKit, SmartThings and Matter and joins 5 GHz networks. The Narwal Freo Z10 Ultra is 2.4 GHz only and supports neither HomeKit, SmartThings nor Matter; its Home Assistant support is not documented.

Detergent

The Roborock Saros 20 dock doses detergent from a 4L clean water tank on its own. Narwal does not document either figure for the Narwal Freo Z10 Ultra, so check it before you count on it.

What owners say

Owners of both flagships agree on two things: they are among the quietest robots they have run, and the obstacle avoidance and mapping handle corners and clutter better than the machines they replaced. Roborock Saros 20 owners single out a slim body that finally cleans under their furniture, suction that lifts dust from floor gaps and a camera they use to check on pets, while they complain that no cleaning solution ships in the box, that some thresholds stop it and that deep-clean runs drain the battery fast. Narwal Freo Z10 Ultra owners talk about hot-water mop washing that ends the musty-mop smell and a base that looks after itself for months, but a few describe full runs lasting hours with errors, trouble climbing thick rugs, an early mop pad failure and slow customer service.

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.
