The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.

02 Assessment

Where they actually differ.

The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

How far apart is a long way?

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

Narwal Flow

The FlowWash rolling track extends mop contact time vs. spinning pads but runs hotter, stressing seal durability under the 12-month warranty.

Real-time hot-water washing keeps the mop clean during the run, but heating water on every wash cycle draws more power than a cold-water dock. Narwal publishes no wattage or annual energy figure for the Flow, so the size of that difference is not stated.

Roborock Q5 Pro+

A bag-only dock and no camera obstacle avoidance keep the price down, but the floor has to be picked up before a run, and no-go zones do the work a flagship’s camera would do while cleaning.

Who each one is wrong for

Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.

Narwal Flow
High-pile or shag carpet environments
The mop track lifts 12 mm when the robot detects carpet, at the top of what this class offers, but shag stays an awkward surface for any track mop: long loops can catch on the roller.
Owners requiring hands-off operation without dock maintenance
The dock's 4.75 L dirty-water tank is emptied and its 5 L clean tank refilled by hand, and dirty water left sitting turns stale. Dust is the long-interval part: Narwal rates the 2.5 L bag at up to 120 days. Not set-and-forget.
Buyers who want a long field record first
The Flow shipped in 2025 on a track-roller mop that is new to Narwal's line. There is not yet a multi-year record of how the roller and its wash mechanism hold up.
Roborock Q5 Pro+
Mixed carpet and hard-floor homes wanting one run to do both jobs
The mop pad attaches by hand, so a run that crosses from hard floor onto carpet means taking the pad off first or fencing the carpet with no-go zones. Vacuuming carpet on its own is well covered: 5,500 Pa and the all-rubber DuoRoller dual brush are built for hair and embedded debris.
Large homes or multi-zone multi-floor layouts requiring dock auto-refill
Q5 Pro+ dock is basic auto-empty only; does not auto-refill water or offer multi-level consumable management. Mop module requires manual water refill.
Owners requiring obstacle avoidance vision (glass tables, cables, transparent barriers)
The Q5 Pro+ maps and routes with PreciSense LiDAR but carries no camera obstacle avoidance, so cables, socks and pet messes are handled with no-go zones and a pre-run tidy rather than recognized on the fly. Transparent barriers and low clearances need setting in the app.

What stays your job

The upkeep ownership hands back to you, whatever the autonomy level says.

Narwal Flow
  • Regularly: Empty the dock’s 4.75 L dirty-water tank and refill the 5 L clean tank. Reviewers report odor where dirty water is left standing.
  • Up to every 120 days: Replace the 2.5 L dust bag; Narwal rates it for up to 120 days of collection.
  • Monthly: Check the roller mop and side brushes for wrapped hair and wipe the LiDAR window.
  • As needed: Rinse or replace the dust filter if suction drops, and replace the roller mop, filters and side brushes as wear shows. Narwal publishes no fixed replacement interval or price for these parts.
  • As needed: Descale the dock’s water path in hard-water areas.
Roborock Q5 Pro+
  • Weekly: Check the DuoRoller rubber brushes for wrapped hair. The all-rubber dual-roller design resists wrapping, but long hair still collects at the bearings. Rinse the mop pad after a mopping run and refill the tank before the next one.
  • Monthly: Filter cleaning or replacement (HEPA cost ~$12); dock inlet and brush inspection.
  • Every 6 to 7 weeks: Auto-empty dock bag replacement (2.5 L E12, ~$15). Roborock rates the bag at up to seven weeks of hands-free operation.
  • Monthly: Wipe the LiDAR turret and the cliff sensors on the underside.
  • Annually: Brush replacement (~$12); full dock mechanics inspection.
05 Evidence

How much each of these is standing on.

Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
