bObsweep UltraVision · Narwal Freo 20 Edge

All robot vacuums. Every measure below is plotted against the full class, so a difference can be read against how much the class itself varies.

01 Classification

What each one does on its own.

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.

V
Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help
III
Conditional
Finishes familiar jobs on its own

II
Assisted
Runs preset routines, needs rescue

Manual
One action, on command
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.

03 Measured against the class

How far apart is a long way?

A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

04 Ownership

What the numbers leave out.

The trade-off

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

bObsweep UltraVision

The dock takes care of dust for up to 180 days; the mop is a cloth you wash yourself.

List price is $929 at bObsweep, yet retailer sales have sold the same model for $299, so the price paid depends almost entirely on timing.

Narwal Freo 20 Edge

Dropping the dual-camera system removes any front-facing lens, which privacy-conscious buyers may welcome, and caps built-in recognition at 150+ object types instead of the standard Freo 20’s 300+.

Owners who mop most days get the most out of the continuous in-run rinse cycle; someone mopping once a week will rarely notice the four-step FlowWash sequence running at all.

The Freo 20 Edge has been on US sale for exactly one week, too brief a window for any independent failure or update record to exist yet.

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.

bObsweep UltraVision
Homes with shag or deep high-pile rugs
bObsweep's own manual says the brush is not suitable for shag, and no published figure covers other high-pile carpet.
Households that want a mop washed and dried by the dock
The mop is a clip-on microfiber cloth with no rotation, no low-water alert and no washing station; owners wash the cloths by hand.
Long-haired households wanting no brush maintenance
Best Buy owners report hair wrapping the brush roll and weekly manual clearing, since the brush has no self-cutting feature.
Networks that broadcast only 5 GHz Wi-Fi
The owner's manual requires a 2.4 GHz connection to reach the app, maps and schedules.
Homes with sunken showers or step-downs left open
One Best Buy owner watched it fall into a shower well on its second run, and the manual warns it may stall on ledges.
Narwal Freo 20 Edge
Buyers wanting the widest obstacle-recognition coverage
The Edge omits the dual-camera system the standard Freo 20 uses, recognizing 150+ object types versus 300+; households with varied clutter may see more missed or mishandled objects.
Owners needing a confirmed long-term reliability record
US sales began 14 Sep 2026; no independent owner reports or failure data exist yet, so buyers wanting a proven multi-year track record should wait or look elsewhere.
High-pile or deep carpet homes prioritizing mop performance
Suction and downforce specs target hard floors and lower-pile carpet; Narwal has not independently published performance figures for thick or high-pile carpet with this specific model.
Buyers wanting documented runtime or battery specs before purchase
Battery capacity, runtime, and charge time have not been independently confirmed for this model; buyers who plan cleaning schedules around a specific runtime figure have nothing to check yet.
Homes needing exact footprint or weight before buying
Independently documented width, depth, and weight are not yet available beyond the 9.5cm body height, complicating placement planning in tight storage spots or under low furniture.

What stays your job

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

bObsweep UltraVision
  • After every use: Wash the microfiber mop cloths by hand and refill the water tank; replacements are $9 for two.
  • Weekly: Clear hair from the main brush, which owners report wraps without a self-cutting feature.
  • Monthly: Clean the dustbin, filter, sensors and charging station contacts, per the owner’s manual.
  • Every 3-6 months: Replace the 6 L dust bag ($11.99), which bObsweep rates for up to 180 days.
  • As needed: Replace side brushes ($9.99) and main brush (from $14.99) when worn.
  • Annually: Inspect the charging station; the manual lists station replacement every 12 months as a guide.
Narwal Freo 20 Edge
  • Every 3-6 months: Replace the auto-empty dust bag (2.5L capacity, rated up to 120 days of use).
  • Monthly: Wipe the hidden dToF LiDAR turret and structured-light sensors to maintain mapping accuracy.
  • Monthly: Descale the dock’s wash chamber to prevent mineral buildup from the water refill cycle.
  • Weekly: Check and refill the dock’s clean-water reservoir if not on a plumbed-in setup.
  • Weekly: Inspect the FlowWash track mop for debris caught at the 4.8cm edge-extension mechanism.
  • As needed: Clear hair or debris from the main brush and side brush.
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.
