Narwal Freo 20 Edge
$799.99
Buy on Amazon USA
It edges out the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock on suction and on runtime, and it mops with a roller that keeps rinsing itself instead of dragging a pad. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is the more affordable of the pair, empties, washes and heat-dries at its dock, and, like the Narwal Freo 20 Edge, connects over 2.4 GHz Wi-Fi only. Both skip Apple Home, SmartThings and Matter, so a Matter-first home is not served by either. Pick the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock for a budget hard-floor vacuum, and the Narwal Freo 20 Edge when mopping is the reason you are buying.

What the differences mean

Mopping mechanism

The Narwal Freo 20 Edge scrubs with a flat roller that fresh water keeps rinsing, and it lifts 12 mm over carpet. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock uses round pads that lift on carpet but cannot rinse themselves mid-run.

Suction

31,000 Pa against 22,000 Pa puts the Narwal Freo 20 Edge ahead on carpet and embedded pet hair, while the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is sized for hard floors and low rugs.

Voice assistants

The Narwal Freo 20 Edge adds Siri control to Alexa and Google Home. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock works with Alexa and Google Home only, and neither robot reaches Apple Home or Matter.

Runtime

The Narwal Freo 20 Edge runs about 210 minutes against 200 on the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock, a difference you would not build a schedule around, since both recharge and resume.

Setup connection

Both the Narwal Freo 20 Edge and the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock carry Bluetooth and connect over 2.4 GHz Wi-Fi only, so neither has the edge here, and a combined router can complicate setup on either.

Which one to buy if

What owners say

Edge and corner work is what Narwal Freo 20 Edge owners bring up most, since the track mop extends past the body and reaches baseboards and chair legs, with a reversing side brush sweeping inside corners. They also rate the rear LiDAR mapping and structured-light avoidance, and the per-room schedules in the app. iRobot Roomba Plus 515 Combo Robot + AutoWash Dock owners report strong pickup on hard floors and pet hair, accurate LiDAR maps and a dock that empties, washes and heat-dries. Both groups call out setup as the step to plan for. Freo 20 Edge owners warn about 2.4 GHz-only Wi-Fi, a large dock that needs clearance, room-temperature mop washing and a long first configuration, while Roomba owners flag mop pads that snag on cords and a loud self-empty.
