Narwal Flow 24.5
4 sources$1,499.99as of Aug 1The Narwal Flow 2 is a top-of-the-line robot vacuum: embedded lidar, dual cameras and a rolling track mop that washes itself while it works, all fed by a dock that empties the bin and dries the mop with heated air. Bob Vila's month with it returned full marks and Basic Tutorials scored it 97 out of 100, though How-To Geek's 7 out of 10 is a cooler read. At $1,499.99 it is priced for people who want the whole system automated, and early owners report mapping and app problems that a machine this expensive should not have.
Strengths
- — Embedded lidar plus dual HD cameras and on-device object recognition
- — 31,000 Pa suction with anti-tangle brush geometry
- — Rolling track mop rinses and scrapes itself while it cleans
Watch-outs
- — Onboard bin holds only 300 ml, so the robot depends on the dock
- — Mapping and app reliability problems reported by early owners
- — Multi-floor navigation is noticeably less efficient than single-floor
