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.

Design and build quality reflect Polaris's 50-year reputation. The unit is heavy at 38.8 pounds but feels rugged. The Easy Lift Removal system is a smart touch: with a button press on the control unit or app, the cleaner climbs to the waterline, evacuates water, and becomes lightweight for easy retrieval. This is a major convenience for users who don't want to strain lifting a wet, heavy cleaner.
Potential drawbacks include the lack of customer reviews, so long-term reliability is unproven. The price is premium, and it requires a stable home WiFi connection for full app functionality.

Buying Guide
Pool Size and Compatibility
Not all pool cleaners are designed to handle a 40-foot inground pool. Robotic models with long cables (70 feet or more) are ideal because they can reach the far end without straining. Pressure-side cleaners like the Polaris Quattro T2 rely on a dedicated booster pump and are built for larger pools, while suction-side units such as the Polaris MAXX work with your existing filtration system. Always check the manufacturer’s recommended maximum pool length before purchasing. For pools with unusual shapes, a robotic cleaner with smart navigation is often the most reliable choice.
Cleaner Type: Pressure-Side vs. Robotic vs. Suction-Side
Each type has strengths. Pressure-side cleaners (e.g., Polaris Vac-Sweep 280) use a booster pump to create powerful suction and can handle large debris like acorns and leaves. Robotic cleaners (e.g., Polaris 9650iQ Sport) are self-contained, energy-efficient, and often include smart features like Wi-Fi scheduling and waterline scrubbing. Suction-side cleaners (e.g., Polaris MAXX) are simpler and cost less but may not climb walls as effectively. For a 40-foot pool, robotic models offer the best balance of coverage and convenience, while pressure-side units excel at heavy-duty debris removal.

Debris Handling and Filtration
A 40-foot pool can accumulate a wide range of debris, from fine silt to large leaves. Look for cleaners with large inlets (2.25 inches or more) and dual-stage filtration that captures both coarse and fine particles. Models like the Polaris Quattro T2 feature a 2.75-inch intake and reinforced canister seals, while robotic cleaners such as the Polaris VRXIQ+ have a large, illuminated canister with a transparent window for easy monitoring. If your pool is surrounded by trees, a pressure-side cleaner with a filter bag may be the best option. For flat-bottom pools, see our best polaris cleaner for flat bottom pools guide.
Navigation and Wall Climbing
To clean a 40-foot pool thoroughly, the cleaner must navigate efficiently and climb walls without getting stuck. Polaris robotic models use four-wheel drive and tangle-reducing swivels to move smoothly across floors and up walls. Pressure-side cleaners like the Quattro T2 employ TankTrax technology for superior traction on steps and slopes. Suction-side cleaners rely on water flow and may struggle with steep inclines. If your pool has a vinyl liner or irregular shape, a robotic cleaner with smart mapping is a safer bet.

Final Thoughts
After evaluating the top contenders, we believe the Polaris Quattro T2 Pressure Side Pool Cleaner is the best choice for owners who want unmatched debris pickup and wall-climbing power in a 40-foot inground pool. Its TankTrax technology and large intake make it a workhorse for heavy debris. For those who prefer a hands-off, smart cleaning experience, the Polaris VRXIQ+ Smart Robotic Pool Cleaner offers Wi-Fi control, multiple cleaning modes, and a large illuminated canister.
