Last recorded price

It is rated at 31,000 Pa against 7,000 Pa on the iRobot Roomba 505X, runs about 210 minutes against 180, and mops with a self-rinsing roller instead of pads. The iRobot Roomba 505X stays in it on price and on a large 3 L water tank, and it is no slouch for hard-floor upkeep. Pick the Narwal Freo 20 for deeper suction, hot-water roller mopping and a quieter run, and the iRobot Roomba 505X for a lower price and a big clean-water reservoir.

What the differences mean

Suction

The Narwal Freo 20 is rated at 31,000 Pa and the iRobot Roomba 505X at 7,000 Pa, so the Narwal pulls far more out of carpet and low-pile rugs. On bare hard floors the iRobot still handles daily dust and crumbs comfortably.

Mop style

The Narwal Freo 20 uses a FlowWash roller that is rinsed in real time by 16 nozzles at 12 N of pressure, so a clean surface keeps meeting the floor. The iRobot Roomba 505X uses spinning pads that are washed and heat-dried at the dock, a simpler wipe rather than a continuous scrub.

Run time

The Narwal Freo 20 is rated for about 210 minutes and recharges in roughly three hours. The iRobot Roomba 505X is rated at 180 minutes, so the Narwal covers more floor before it has to stop.

Noise

The Narwal Freo 20 is rated at 56.9 dB in Quiet Mode, quiet enough to run with company over. The iRobot Roomba 505X publishes no figure, and owners describe its cleaning cycle as noticeably loud, especially on a deep-clean setting.

Water and dust handling

The iRobot Roomba 505X carries a 3 L clean-water tank and empties into a dock rated for about 75 days. The Narwal Freo 20 empties into a 2.4 L bag rated for up to 120 days, but its water tank capacity is not published.

What owners say

Owners of both robots praise the same end result, floors that stay clean with little effort, but they describe different strengths. iRobot Roomba 505X owners point to accurate LiDAR mapping, a large water reservoir and reliable pickup of pet hair and dust, and they credit the AutoWash dock with handling the chores; their complaint is noise, with the deep-clean cycle loud enough that many schedule it for when they are out. Narwal Freo 20 owners lead with mopping, describing brown water draining from the dock after the first run and edges and baseboards that finally look clean, and they call it quiet even when it washes itself. Their warnings are about software, a Wi-Fi setup that took several attempts and an app that carries in-app promotions and occasional navigation glitches.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
