Dolphin W20 or Aiper Scuba X1 — which wins?
Our Recommendations

Explained
Compare Features in Detail
Smartphone App Control
App connectivity can put scheduling, cycle selection and cleaner status on your phone, although the exact controls vary by model.
Dual Stabilizer
Essential for waterline cleaning, dual stabilizers let the unit cling to the walls for a more precise, deeper clean at the waterline — with increased agility and an easy pickup handle.
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 Aiper Scuba X1 is backed by a 2-year warranty, while the Dolphin W20 carries a 3-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.
