Updated September 2026

Data from Amazon and official iRobot and Narwal sites.

2026 verdict

Winner

$999.99

Suction is where this robot vacuum comparison is decided: the Narwal Flow pulls 22,000 Pa against the iRobot Roomba Plus 505's 7,000 Pa, on top of a higher owner rating, longer runtime and broader connectivity with Bluetooth added to its dual-band Wi-Fi. The iRobot Roomba Plus 505 answers with a lower price and matches the Narwal Flow on everything else that ties: self-washing and self-drying mop pads, a self-emptying dock, laser navigation with no-go zones, and the same six ecosystem integrations including Matter and Apple Home. Buyers who want the strongest suction and the longest runtime should choose the Narwal Flow; anyone prioritizing price over raw pulling power still gets a fully automated vacuum-and-mop routine from the iRobot Roomba Plus 505.
