Polaris VRX iQ+ review
Best dealer-serviced premium
8.8/10Editorial score · Updated 2026-07-03
A dealer-backed premium corded robot with app control, a huge filter canister, and Polaris' decades-deep service network.
Quick verdict
The premium pick for buyers who value a dealer service network over cordless convenience. It cleans everything, holds a lot of debris, and parts are easy to get.
Good fit if you want
- Large in-ground pools
- Owners who want local dealer service
- Heavy debris loads (big canister)
Skip it if you need
- Anyone set on cordless
- Budget buyers
The full picture
The VRX iQ+ is Polaris' answer to premium corded cleaning: four-wheel-drive traction, floor-wall-waterline coverage, a large easy-clean filter canister, app control with scheduling, and a caddy for storage. Because Polaris sells heavily through pool dealers, in-person service and parts are easier to come by than for import brands — a real consideration for a machine you expect to run for many seasons. The tradeoffs are the cable (long, but still a cable) and a price in flagship territory without being cordless.
