Dolphin Wave 90i or Niya Sonar Ray — which wins?

Our Recommendations

Hands-Off Weekly Timer

An automatic pool cleaner should be automatic. A true weekly timer runs a complete pool-cleaning cycle on schedule — every day, every other day, or a few times a week — without you retrieving or recharging the robot between cycles. An app schedule on a cordless robot is not hands-off if the cleaner still has to be removed and recharged between cycles, so Poolbots does not count that as a true weekly timer.

Smartphone App Control

App connectivity can put scheduling, cycle selection and cleaner status on your phone, although the exact controls vary by model.

Dolphin Wave 90i includes this

Anti-Tangle Cable Swivel

Say goodbye to tangled cords. An anti-tangle swivel lets the robot move 360° around your pool without the cord getting tangled, so you can sit back while it cleans. Learn more ›

Warranty Coverage

A robot is only as good as its warranty. The Niya Sonar Ray is backed by a 1-year warranty, while the Dolphin Wave 90i carries a 2-year warranty. Buying through an Authorized Dealer like Poolbots gets you the full manufacturer warranty — never pro-rated or limited by cleaning cycles — plus a 30-day in-pool trial with no restocking fees.
