Autonomy Ladder

Why Level II.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyHandles new obstacles and re-plans in real time; rare in consumer products.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Pentair Warrior SE runs preset routines on its own, and the owner is its recovery system.

Navigation and control
Random floor search pattern; dual brush contact navigation.
Why this level
- The robot follows a predetermined random search pattern without environmental mapping or obstacle detection.
- Dual brush motors provide consistent contact; no adaptive pathfinding qualifies this as Level II.
Autonomy dimension 40 / 100 · 2 sources reviewed
IManual AutomationOne action on command; no independent operation.

Human Readiness

Ready Now.

The Warrior SE (360494) is discontinued. Pentair's current equivalent is the Prowler 920, which shares its manual and replacement-parts sheet, so remaining retail listings are closeout stock rather than a live product line. Setup is short but electrical: a GFCI-protected receptacle at least 12 feet from the pool edge, connected without an extension cord, then the unit goes in the water and runs on demand or on the power supply's weekly timer. Routine upkeep is rinsing the filter basket after each cycle.

Where this sits on the readiness scale

Ready NowThis robotProven autonomous performance, reliable, and available for purchase.
Promising ProgressReal advancement, but the ownership experience is still maturing.
OverhypedMarketing is outpacing actual capability.
WaitTechnology exists but better options are coming soon.

Robovations Score

Why the score is withheld

Not scored

The Robovations Score is withheld on this record. It is not a low score, and it is not an oversight.

Why

Our assessment did not establish an independent source for 5 of the nine inputs: task completion, coverage and navigation, edge-case recovery, operating envelope, software stability.

The full assessment note

Those inputs carry 54% of the composite between them, so a number published here would be reporting the state of the record rather than the state of the machine. The unevidenced anchor is a reference point for one input, not a foundation for a whole score.

What would change it

An independent account of its task completion that we have verified.
An independent account of its coverage and navigation that we have verified.
An independent account of its edge-case recovery that we have verified.
An independent account of its operating envelope that we have verified.
An independent account of its software stability that we have verified.

Five-year cost$1,049

lower-middle for robotic pool cleaners; the record carries no MSRP and the machine is closeout, currently listed near $899 without the caddy and around $1,350 bundled with it, so roughly $150 is assumed over five years for brushes and a spare screen set, with no subscription and no scheduled filter purchase

Common questions

What people actually ask.

5 answered

OperationDoes the Warrior SE reach the pool walls and waterline?

Yes. Pentair’s guide describes the unit as scrubbing, vacuuming and filtering the pool including the waterline, and it is sold as covering floor, cove, walls and waterline with high-speed rotary scrubbing.

OwnershipWhat does filtration cost to maintain, and how often?

Filtration runs through a top-loading basket carrying reusable screens, and the unit ships with two sets, ultra-fine and spring. Pentair’s instruction is to rinse the basket after each cleaning cycle. No Pentair document sets a replacement interval or a price for the screens.

OperationHow long does a typical cleaning cycle take?

Most floor coverage occurs within 1.5 to 2.5 hours. Random search means no guaranteed complete coverage; longer cycles may be required for heavy debris.

OperationCan I use the Warrior SE in saltwater pools?

Pentair models are typically chlorine-designed. Saltwater requires corrosion-resistant materials; confirm with Pentair support before use in saltwater systems.

OperationWhat happens if the power cord gets caught on a pool edge?

The cable is not motorized or retractable, so a snag needs attention. Unplug the power supply before handling the cable, and do not reach into the water for it while the unit is running. Remove the cleaner from the pool before anyone swims.
