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.
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.

Not compared, because fewer than two of these robots carry a published figure: Charge time, Height.
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.
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.
Automatic recognition of up to four levels removes the manual map step, but every level still shares one dock, so the robot has to be carried between them.
The roller mop is washed by the dock during the run rather than swapped by hand, which removes the pad-changing chore and adds a dock that needs a permanent level spot with mains power.
Cloud-enabled scheduling and remote starts tie operation to WiFi availability and account login for full feature set.
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.
- 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.
- Homes undergoing frequent renovations or furniture rearrangement
- LiDAR maps require updates after major layout changes. Not ideal for homes with items moving week-to-week.
- Homes that are wall-to-wall thick or high-pile carpeting
- The roller mop lifts up to 15mm automatically when carpet is detected, so carpeted rooms are vacuumed rather than mopped. Nothing has to be removed and no mode has to be selected, but a fully carpeted home uses little of what the mopping dock is for.
- Privacy-first users avoiding cloud account requirements
- Full app features require WiFi registration and account creation. Local-only operation models exist with less advanced mapping.
- Frequent-obstacle homes expecting minimal user intervention
- Level III autonomy handles pre-mapped spaces but temporary clutter requires app-based zone exclusion. Daily obstacle clearing still expected.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
- 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.
- After every use: Nothing. The dock empties the bin and washes and dries the roller mop.
- Weekly: Wipe the sensor windows on the top and underside, check the side brush for wound hair.
- Monthly: Wash or replace the filter, rinse the dock wash tray, check the clean and dirty water tanks.
- Every 3-6 months: Replace the dust bag as the app prompts, deep clean the wheels and brush head, inspect the dock water line for mineral buildup.
- Annually: Replace the main brush and the mop roller if not already done, drain the dock and clean the reservoir filter, run a descaling cycle in hard-water areas.
- As needed: Remap floors if the home layout changes, troubleshoot WiFi if the connection drops, clear any stuck debris.
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.
