Pros
- LiFi remote control for precise underwater navigation and retrieval
- iAquaLink app integration for remote monitoring and mode selection
- Cordless design with outdoor-rated charging caddy for easy transport and storage
- Three retrieval methods for flexibility and convenience
- Trusted Polaris brand with a reputation for durable, high-performance cleaners
Cons
- Premium price point may be a barrier for budget-conscious buyers
- Requires WiFi for full app functionality, which may be a limitation in areas with poor connectivity
- No built-in skimmer or leaf canister for heavy debris, making it less suitable for pools with large leaves
The Polaris Freedom Plus Cordless Robotic Pool Cleaner is a top-tier solution for in-ground pool owners seeking a hands-free, intelligent cleaning experience. It combines the convenience of cordless operation with advanced connectivity, making it ideal for those who want to automate pool maintenance without being tethered to a power outlet.
Standout features include the LiFi hand-held remote that communicates with the cleaner underwater, allowing you to direct it to the waterline for easy retrieval. The iAquaLink app adds another layer of control, letting you check charging status, select specialized cleaning modes, and receive push notifications when a cycle ends. This means you can manage your pool cleaner from anywhere, whether you are at home or away.
Design and build quality reflect Polaris's 50-year heritage: the cleaner is rugged, weather-resistant, and the outdoor-rated charging caddy simplifies transport and storage. The unit charges fully in five hours or less, and the cordless design eliminates tangles and tripping hazards. However, at 40.8 pounds, it is sturdy but not overly heavy, and the quick water release feature makes lifting it out of the pool manageable.
Potential drawbacks include the premium price, which may deter budget-focused buyers, and the reliance on WiFi for full app functionality. Additionally, while it handles standard dirt and debris well, it lacks a dedicated leaf canister, so owners of pools with heavy leaf accumulation might need supplemental cleaning. The three retrieval methods do offer flexibility, but the manual retrieval hook requires a standard pole, which is not included.
Overall, the Polaris Freedom Plus is a high-quality robotic cleaner that delivers on its promises of convenience, control, and cleaning power. It is best suited for pool owners who value smart home integration and are willing to invest in a premium, cordless solution. For those with simpler needs or tighter budgets, alternatives may exist, but for a seamless, app-driven cleaning experience, this model stands out.

Buying Guide
Cleaning Performance and Coverage
The Polaris 9650iQ Sport (closely related to the Polaris 9550 Sport Robotic Pool Cleaner) uses 4WD and Vortex Vacuum technology to suspend debris while scrubbing floors, walls, and the waterline. It offers five cleaning modes, including a fast clean cycle for quick touch-ups. The Zodiac VRX iQ Plus relies on a similar dual-brush system but adds a dedicated filter canister that traps larger leaves before they reach the pump. For pools with heavy leaf loads, the VRX iQ Plus may require less frequent filter emptying.
Both models climb walls effectively, but the Polaris 9650iQ Sport includes a motion-sensing remote that lets you steer the robot to missed spots. The VRX iQ Plus uses a standard remote and relies on its onboard computer for path planning. If wall-climbing brush quality matters, see our best pool cleaner wall climbing brush guide for upgrade options.
Navigation and Smart Features
Smart navigation separates premium robots from basic ones. The Polaris 9650iQ Sport uses a gyroscopic sensor to map your pool and avoid obstacles. It also features a tangle-reducing swivel cable (compatible with the Polaris Replacement Swivel Floating Cable Assembly) to prevent cord snags. The Zodiac VRX iQ Plus employs a similar gyro system but relies on a simpler algorithm that may leave some areas uncovered on the first pass. However, the VRX iQ Plus can be controlled via a smartphone app (iAquaLink) for remote start and cycle monitoring, a feature the Polaris lacks unless you upgrade to the Freedom Plus cordless model.
For pools with complex shapes, the Polaris often finishes faster because of its adaptive cleaning patterns. If you prioritize app control, the VRX iQ Plus is the better choice. Compare other smart cleaners in our dolphin liberty 300 vs liberty 400 article.
Ease of Maintenance and Parts Availability
Both robots require regular filter cleaning and occasional part replacements. The Polaris 9650iQ Sport uses a large 5-liter canister that is easy to rinse. The Zodiac VRX iQ Plus uses a similar canister but adds an inlet housing filter (the Zodiac Polaris Filter Canister Inlet Housing) that catches debris before it reaches the main pump, reducing clogs. For motor issues, the VRX iQ Plus has a dedicated replacement part: the Zodiac R0865400 Polaris Motor Block Type 2, which simplifies repairs. The Polaris 9650iQ Sport shares many parts with the 9550 Sport, including the swivel cable assembly, making replacements easy to find.
If you plan to keep your cleaner for years, check what spare parts are available. The VRX iQ Plus has strong support from Zodiac, while Polaris parts are widely sold online. Our best pool robot traction brush guide can help you maintain grip performance over time.
Pool Size and Compatibility
The Polaris 9650iQ Sport (and its sibling 9550 Sport) handles pools up to 60 feet in length, thanks to a 70-foot cable. The Zodiac VRX iQ Plus is rated for pools up to 50 feet with a 60-foot cable. For larger pools, the Polaris provides better reach without needing an extension. Both robots work with in-ground pools only. If you have an above-ground pool, see our Above Ground Pool Cleaners category for alternatives.
Final Thoughts
Choosing between these two premium robots comes down to your priorities. If you want faster cleaning cycles, a longer cable, and a proven track record of floor-to-wall coverage, the Polaris 9550 Sport Robotic Pool Cleaner (the closest available model to the 9650iQ Sport) is a reliable workhorse. If you prefer app control, a dedicated leaf-trapping filter, and easy motor replacement, the Zodiac Polaris Filter Canister Inlet Housing (a key part of the VRX iQ Plus system) points to a cleaner that simplifies long-term ownership. Both deliver sparkling results, so let your pool size and maintenance preferences guide your decision.
