The Proteus DX3 holds 66% five-star ratings as a corded pool robot that climbs walls and traps fine sand for hundreds less than a Polaris. First-year motor failures and a pokey cleaning pattern are the gambles you take at this price.

Best for: In-ground pools up to 33 feet where you want plug-in robotic scrubbing without installing a booster pump, not buyers who expect multi-year reliability without warranty shipping headaches.

Loved by buyers

  • Top-access filter basket catches oak tassels, sand grit, and sweet-gum balls without mid-run clogging
  • Wall-scrubbing climb reduces how often you need to brush plaster and vinyl by hand
  • Corded plug-in means zero battery downtime between back-to-back cleaning cycles
  • Drains fast and weighs less than older Polaris bots when hauling it out of the water

Buyer concerns

  • Constant stop-and-reverse makes it look lost, even when the pool ends up clean by the end
  • Stairs get no coverage at all; bench seats get a partial pass at best
  • Several owners had the controller or motor die within the first year and faced steep return shipping
  • One full cycle runs noticeably longer than a Polaris on the same size pool
