Polaris' flagship corded robot runs a SMART cycle that sizes up the pool and sets its own cleaning time, reports to the iAquaLink app, and climbs to the waterline at the touch of a button so it can be lifted out already draining.

Best for: Large in-ground pools where the owner wants to press a button and lift, not fish

Dolphin Sigma: what it gives up

  • The most expensive corded robot in the catalog
  • Published weight, suction and dimensions match the $1,349 CC Supreme's; the gap is warranty and brushes
  • 24.6 lb, tied with the CC Supreme as the heaviest corded Dolphin
  • No filter-full light, which the cheaper Premier and Explorer E50 both have
  • No caddy is listed in the box at this price

Polaris VRX iQ+: what it gives up

  • Polaris publishes no weight, maximum pool size or micron figure for it
  • No per-model warranty term on Polaris' page
  • $1,499 in Polaris' rebate terms, $350 more than the EPIC 8642 iQ
  • In-ground only, like every Polaris in the catalog
