Its FlowWash roller rinses itself with hot water as it scrubs, it speaks Matter for Apple Home, SmartThings and Home Assistant that the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock cannot reach, and its 31,000 Pa motor and dual-band Wi-Fi edge out the Roomba 22,000 Pa and 2.4 GHz-only radio. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is the more affordable of the pair and still empties, washes and heat-dries its pads at its dock, but its mopping is a pad system that can snag on cords. Choose the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock for budget and hard-floor vacuuming, and the Narwal Freo 20 for edge-to-edge mopping and a wider smart home reach.

What the differences mean

Mopping system

The Narwal Freo 20 uses a rolling track mop that rinses itself with hot water through 16 nozzles at 12 N of pressure, so it scrubs with clean water. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock drags a pad it only washes back at the dock.

Suction and carpet

31,000 Pa against 22,000 Pa favors the Narwal Freo 20 on carpet and pet hair, while the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is at its best on hard floors and low rugs.

Wi-Fi bands

The Narwal Freo 20 accepts both 2.4 GHz and 5 GHz networks, which makes pairing easier on a modern router. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is 2.4 GHz only, the setup headache owners mention most.

Smart home platforms

Matter puts the Narwal Freo 20 into Apple Home, SmartThings and Home Assistant next to native Alexa and Google Home. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock stops at Alexa and Google Home.

Runtime

The Narwal Freo 20 runs about 210 minutes against 200 on the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock, a gap small enough that you would not plan a floor around it. Both return to recharge and resume.

What owners say

Narwal Freo 20 owners describe watching brown water drain from the dock after a first run and taking that as proof the roller lifted dirt instead of pushing it around, and they single out edge and corner coverage, dual-camera obstacle avoidance and quiet running. iRobot Roomba Plus 515 Combo Robot + AutoWash Dock owners report strong suction on hard floors and pet hair, accurate LiDAR mapping and a dock that empties, washes and heat-dries. Both groups warn that the large room size on the box assumes a single air change, and both name app setup as the step to plan for. Freo 20 owners also mention navigation glitches and an unfinished app, while Roomba owners flag 2.4 GHz-only pairing and mop pads that catch on cords.

Frequently Asked Questions

Which is better overall: the Narwal Freo 20 or the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock?

The Narwal Freo 20 for a hard-floor home. It wins on suction, mopping, runtime, connectivity and smart home support, and its roller mop cleans better than pads. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is the more affordable vacuum-first choice.

What is the biggest difference between the Narwal Freo 20 and the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock?

The mop. The Narwal Freo 20 rinses a rolling track mop continuously with hot water, while the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock drags a pad that is only cleaned back at its dock.

Does the Narwal Freo 20 work with Apple Home and Matter?

Do these robots need 5 GHz Wi-Fi?

Neither needs it, but the Narwal Freo 20 supports both 2.4 GHz and 5 GHz, while the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is 2.4 GHz only, so a combined router may need its bands split during setup.
