2026 verdict
Hot-water mop washing is what the Shark PowerDetect Self-Empty lacks, and it is why the Narwal Freo Z10 Ultra is the better robot vacuum of the two.

Narwal Freo Z10 UltraLast recorded priceOct 8, 2026$1299.99
Currently unavailable on Amazon USA
The Narwal mops, and its station washes and dries the mop, lifts it over rugs and empties a 2.5 L bag; it also runs 150 minutes against 110, is rated at 18000 Pa and owners rate it higher. The Shark PowerDetect Self-Empty is a far cheaper, vacuum-only robot with LiDAR mapping, a self-emptying base and Home Assistant support that the Narwal does not document. Both work with Alexa and Google Home, and neither supports Apple Home, SmartThings or Matter. Choose the Narwal Freo Z10 Ultra for vacuuming and mopping with little upkeep, and the Shark PowerDetect Self-Empty for affordable pet hair vacuuming.

What the differences mean
Mopping
The Narwal Freo Z10 Ultra mops, and its station washes and dries the mop and lifts it over rugs. The Shark PowerDetect Self-Empty does not mop, so hard floors still need a hand mop.
Battery
150 minutes on the Narwal Freo Z10 Ultra against 110 on the Shark PowerDetect Self-Empty. Both recharge and resume.
Suction
The Narwal Freo Z10 Ultra is rated at 18000 Pa. Shark does not publish a figure for the Shark PowerDetect Self-Empty, although its owners praise its pet hair pickup.
Smart home
Both work with Alexa and Google Home. The Shark PowerDetect Self-Empty also lists Home Assistant, which is not documented for the Narwal Freo Z10 Ultra. Neither has Apple Home, SmartThings or Matter.
Which one to buy if
- you want the mopping done too
Only the Narwal Freo Z10 Ultra mops, and its station cleans the mop with hot water.
- you need an affordable vacuum for shedding pets
The Shark PowerDetect Self-Empty costs far less and pet owners say it keeps ahead of shedding.
- noise matters because you run it while home
Narwal Freo Z10 Ultra owners repeatedly call it the quietest robot they have owned.
- you automate with Home Assistant
The Shark PowerDetect Self-Empty lists Home Assistant support; the Narwal does not document it.

What owners say
Owners of both robots are largely pet households, and both groups say they keep up with shedding dogs. Narwal Freo Z10 Ultra owners single out how quiet it is, obstacle avoidance and edge cleaning better than the robots they replaced and hot-water mop washing that ended the musty-mop smell, while they complain that full vacuum-and-mop runs can take hours, that thick area rugs confuse it and that customer service is slow. Shark PowerDetect Self-Empty owners like a taller body that no longer wedges under furniture and navigation that does not get lost, and they criticise a basic app, awkward Wi-Fi pairing, missed patches and a base that fills faster than they expected.
