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
I
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.

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.
Dreame L60 Ultra PE
Priced below the L60 Pro Ultra sibling, but ships without ProLeap’s leg-lift mechanism, capping threshold crossing at roughly 22mm versus the sibling’s 88mm two-step rating.
Uses notably less water during mopping than the category average, which independent testing linked to below-average stain removal despite strong real-world carpet and pet-hair results.
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.
Dreame L60 Ultra PE
- Homes with thresholds above roughly 22mm
- Independent testing found it fails to cross a 25mm threshold; it has no leg-lift mechanism like the L60 Pro Ultra sibling.
- Buyers prioritizing stain removal
- Independent testing measured stain-removal scores below the category average, linked to low water usage during mopping.
- Buyers needing a confirmed multi-year reliability record
- The model launched around April 2026; independent field and failure data remain limited to one initial review.
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.
Dreame L60 Ultra PE
- Weekly: Check the Detangling DuoBrush and side brush for wrapped hair and debris; standard robot-vacuum practice, since Dreame publishes no public maintenance schedule for this SKU.
- Monthly: Wipe the AI camera window, 3D time-of-flight sensor, cliff sensors, and charging contacts with a dry cloth; likewise on no published interval.
- As needed: Refill the dock’s water tank and detergent; automatic detergent dispensing and the 212F hot-water mop wash stop without them.
- As needed: Replace the dock’s 3.2 L dust bag; no capacity-in-days rating was found for this SKU.
- As needed: Empty the 250 ml onboard dustbin between dock visits; independent testing notes it is smaller than category norms and may need more frequent attention.
- As needed: Replace the mop pads, dust box filter, and brushes as they wear; Dreame’s official accessory kit ($149.99) bundles a DuoBrush, two side brushes, two dust bags, two filters, cleaning solution, and six mop pads.
- As needed: Revisit no-go zones, multi-floor maps, and schedules in the DreameHome app after floor-plan changes.
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.
