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

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.
Dreame L50s Pro Ultra
100°C mop washing and a 4 cm climb are the headline, and no independent test has yet measured either.
The dock handles dust for up to 100 days; water still means tanks unless you buy the hookup kit.
iRobot Roomba Plus 415 Combo
Water-only pad washing skips a chemical cartridge to refill, and skips the deeper stain-lift a detergent wash cycle adds elsewhere in iRobot’s lineup.
No published per-charge runtime: buyers get a 330-minute charge time and no way to know how long one cleaning session actually lasts.
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.
Dreame L50s Pro Ultra
- Buyers in the United States
- Dreame sells it in India and a Benelux retailer lists it; no US sale is announced.
- Owners who never want to handle water tanks
- The 4.5 L clean and 4.0 L used tanks are filled and emptied by hand unless the separately sold water hookup kit is fitted.
- Buyers who want independent cleaning results first
- Smartprix has published only first impressions, with a full review still to come; no outlet has published test results.
- Low furniture under 11 cm
- Dreame lists the robot at 103.8 mm tall.
iRobot Roomba Plus 415 Combo
- Households needing a documented per-charge runtime figure
- iRobot has not published a per-charge runtime figure for this model, only a 330-minute charge time for the 5200mAh battery, leaving coverage-per-charge unconfirmed for buyers who need that number before deciding.
- Owners wanting automatic detergent dispensing at the dock
- The AutoWash Dock washes and heat-dries the DualClean mop pads with water only; buyers wanting an automatic cleaning-solution cycle for dried-on messes need a different dock tier.
- Buyers prioritizing the strongest suction in iRobot's combo lineup
- At 20,000 Pa, this model is the entry point among iRobot's current AutoWash Dock combos; buyers wanting the strongest suction in that lineup should compare other current models.
- Thick, deep-pile carpet homes
- No independent test of thick-pile performance was found, and 20,000 Pa is the lowest published suction figure among iRobot's current wash-dock combo models, so performance on heavy shag or high-pile rugs remains unverified.
- Buyers requiring a multi-year ownership track record
- The Plus 415 Combo launched summer 2026 with no independent hands-on reviews published yet; owners wanting years of documented field reliability should wait or choose a longer-tenured model.
What stays your job

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.
