Winner
Narwal Freo Z10 UltraLast recorded priceOct 8, 2026$1299.99
Currently unavailable on Amazon USA
It is rated at 18,000 Pa against 7,000 Pa, runs 150 minutes against 120, and the dock washes and dries the mop, lifts it for carpet and self-empties into a 2.5 L bag. The iRobot Roomba 205 does not mop and does not self-empty. It is the more affordable robot vacuum, and it joins 5 GHz Wi-Fi, which the Narwal Freo Z10 Ultra does not. Neither lists Apple Home or Matter. Pick the Narwal for mopping and suction. Pick the Roomba for a cheaper vacuum with a small base.

What the differences mean
Mopping station
The Narwal Freo Z10 Ultra mops, washes and dries the pads and lifts them for carpet, and it self-empties into a 2.5 L bag. The iRobot Roomba 205 does none of that. It is a vacuum with an internal compactor and a small charger. If you want a mop maintained at the dock, the Roomba is not in the conversation.
Suction and runtime
The Narwal Freo Z10 Ultra is rated at 18,000 Pa and 150 minutes. The iRobot Roomba 205 is rated at 7,000 Pa and 120 minutes, and it charges in 5 hours. The Narwal charge time is not published. The suction gap is the one you would notice on pet hair.
Wi-Fi
The iRobot Roomba 205 joins 5 GHz and 2.4 GHz, with Alexa and Google Home. The Narwal Freo Z10 Ultra is 2.4 GHz only, also with Alexa and Google Home. It does not list Apple Home, SmartThings or Matter. Home Assistant on the Narwal is not documented. The Roomba does not list Home Assistant.
Size
The Narwal Freo Z10 Ultra measures 355 x 350 x 109.6 mm and weighs 4.5 kg, with a dock of 430.8 x 462 x 388.3 mm. The iRobot Roomba 205 measures 358 x 358 x 101 mm. Its weight and dock size are not published, which fits the small-base design owners describe rather than a full station.
Which one to buy if
- you want the dock to mop, wash and empty
The Narwal Freo Z10 Ultra washes, dries, lifts and self-empties. The iRobot Roomba 205 only compacts vacuum debris.
- you want the cheaper vacuum and 5 GHz Wi-Fi
The iRobot Roomba 205 is the more affordable robot and joins 5 GHz. It does not mop or self-empty.
- pets and hard floors need a real mop
At 18,000 Pa, with hot-water mop washing that owners praise, the Narwal Freo Z10 Ultra is built for that job. The Roomba stops at vacuuming.
- a bulky dock will not fit
The iRobot Roomba 205 uses a compact charger. The Narwal Freo Z10 Ultra dock is a full station, about 431 x 462 x 388 mm.

What owners say
Owners of the iRobot Roomba 205 and the Narwal Freo Z10 Ultra are not praising the same job. iRobot Roomba 205 owners single out fewer trips to the trash because debris is compacted inside the robot, and a small base instead of a tower, while they keep saying a full floor needs extra charges. Narwal Freo Z10 Ultra owners single out quiet running, obstacle avoidance that still gets close to furniture, and hot-water mop washing that stops the musty-pad problem. Their complaints are long vacuum-and-mop runs, thicker rugs that confuse it, and slow customer service. Warranty length for the Narwal is not published.
