Narwal Flow vs Roborock Saros 20

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Narwal and Roborock sites.
2026 verdict
Suction is the Roborock Saros 20's clear advantage, at 36,000 Pa against the Narwal Flow's 22,000, but the Narwal Flow still wins this robot vacuum comparison on price, owner rating, connectivity and a larger water tank for mopping.
Both are flagship self-washing combos that empty, wash and dry themselves, run about 200 minutes per charge, and reach the same six ecosystem integrations including Matter, Apple Home and Home Assistant. If raw suction on carpet and thick rugs is the priority, the Roborock Saros 20 pulls ahead; if you'd rather pay less for a slightly higher-rated machine with more water capacity for mopping, the Narwal Flow is the pick.
