Polaris Alpha iQ+ · Polaris EPIC 8642 iQ

All robot pool cleaners. 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

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.

Not compared, because fewer than two of these robots carry a published figure: Suction, Runtime, Charge time, Noise, Weight, Height.

04 Ownership

What the numbers leave out.

The trade-off

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

Polaris Alpha iQ+

You are paying for mode coverage and a cycle that times itself, not for a machine that handles its own debris. The canister still comes out by hand after every run.

Mains power buys cycle length no battery matches, and costs you a cable in the water. The Easy Lift Removal System takes the worst of the retrieval friction out; the coiling and the outlet dependency remain.

Polaris EPIC 8642 iQ

The iAquaLink app is real convenience, but corded operation is tethered convenience, cable management creates logistics that offset the app’s hands-off promise.

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.

Polaris Alpha iQ+
Portable or temporary pool installations
Mains-fed operation needs a permanent GFCI-protected outlet within reach of the power supply's own cord. Extension cords are not used on a submerged appliance, so reach is a hard limit rather than something to work around.
Owners who want no involvement between cycles
The debris canister comes out by hand after a run and the cable is coiled for storage. The Easy Lift Removal System brings the cleaner to the waterline on its own, but lifting it out and clearing the canister are still manual steps.
Pools longer than the supplied cable will reach
Cable run, not pool volume, sets the working envelope. Measure the longest run from the outlet to the far end of the pool before purchase and confirm the supplied length with the dealer.
Polaris EPIC 8642 iQ
Above-ground pools and small in-ground pools.
Polaris rates the EPIC 8642 iQ for in-ground pools up to 50 feet, and the 60 foot cable, control box and transport caddy are sized for that installation. On a compact pool the handling routine is the same as on a large one, and that routine is most of the ownership effort.
Owners preferring cordless or minimal cable management.
The 60 foot cable is not optional on this model. It runs from the cleaner to a poolside control box, the swivel reduces tangling rather than removing the cord from the routine, and the cleaner and caddy need storage between uses. As with any mains-fed cleaner, it comes out of the pool before anyone swims.
Environments with heavy brush or concrete surface damage.
Brush wear on rough surfaces accelerates; brush replacement intervals will increase and consumable costs rise.

What stays your job

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

Polaris Alpha iQ+
  • After every use: Lift out the debris canister and empty it. Polaris describes the canister as cleared with a few shakes and a spray from a hose.
  • Weekly: Rinse the filter media and check the brushes for embedded debris, cost $0.
  • Monthly: Inspect the cable and the tangle-reducing swivel for wear or abrasion, cost $0.
  • Seasonally: Store the cleaner and its power supply indoors in freezing climates when the pool is closed.
  • As needed: Replace brushes or the cable assembly through a Polaris dealer. Polaris publishes no replacement interval or price for either.
Polaris EPIC 8642 iQ
  • After each run: Lift out the 4 L filter canister and rinse the debris (~10 min); check the cable swivel.
  • Every 2-4 weeks: Deep-clean the canister if debris load is heavy; wipe the brush cartridge.
  • Every 6-12 months: Replace brush cartridge (~$60-80 typical Polaris pricing).
  • Annually: Replace filter canister (~$120).
  • Seasonally: Store the cleaner, caddy and control box indoors and out of freezing conditions; inspect the cable and its connector for corrosion; check wall-climb wheels for algae film.
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.
