Pros
- Smart app gives full remote control, scheduling, and troubleshooting from your phone
- Powerful cyclonic suction and dual brushes clean both floor and walls effectively
- Easy Lift feature makes removal and draining simple and lightweight
- Large debris canister reduces emptying frequency and is easy to clean
- Included caddy and cover add value and protect the unit between uses
Cons
- Corded design limits range to the length of the cord, which may require repositioning for very large pools
- Higher price point compared to basic suction-side cleaners, though the smart features and performance justify it
- App setup and connectivity may be an extra step for users who prefer simple push-button operation
The Polaris ERA 842 is a premium corded robotic pool cleaner designed for inground pool owners who want hands-off maintenance and smart convenience. It pairs Polaris's proven cleaning power with modern app control, making it a strong choice for tech-savvy homeowners who value scheduling and remote monitoring.
Out of the box, the ERA 842 impresses with its robust build and thoughtful design. The dual-traction motors and cyclonic vacuum work in tandem to climb walls and capture debris from the floor to the waterline. Front and back scrubbing brushes loosen stuck-on grime, and the large canister holds plenty of dirt between empties, so longer cleaning sessions are practical.
The standout feature is the smart app control. You can start or stop a cycle, choose floor-only or floor-and-wall coverage, set a schedule, and even trigger the Easy Lift system from poolside. Easy Lift drives the unit to the surface and drains it, which makes removing the cleaner remarkably easy. The included transport caddy and protective cover are welcome extras that keep the unit organized and shielded when not in use.
Potential drawbacks are few but worth noting. The corded design means you are limited by the tether length, and very large pools may require moving the power unit to cover all areas. The price is on the higher end, though the feature set and Polaris reliability help justify the investment. App connectivity is an extra layer that some users may find unnecessary if they prefer direct controls.
Overall, the Polaris ERA 842 is a feature-rich, high-performance robotic cleaner that excels in convenience and cleaning quality. For pool owners who want app-based control, effortless removal, and dependable wall climbing, this is a top-tier option that should deliver years of service.
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.

The Polaris VRXIQ+ Smart Robotic Pool Cleaner is a premium automatic cleaner designed for large in-ground pools. It combines intelligent cleaning algorithms with robust hardware to deliver a thorough, hands-free experience. This model is best suited for pool owners who want app-based control and minimal manual intervention.
Its standout feature is the Smart Cycle Cleaning Mode, which analyzes your pool's shape, size, and surface to calculate the most efficient cleaning time. This means it does not run longer than necessary, saving energy and wear. The iAquaLink app adds another layer of convenience, allowing you to schedule cleanings, check water temperature, and receive alerts directly on your phone.
Performance is driven by Vortex Vacuum technology and four-wheel drive agility. The cleaner climbs walls and tackles waterline debris with ease. The 70-foot cable with a swivel connector reduces tangles, making it suitable for larger pools. The illuminated debris canister is a thoughtful touch: a transparent window and built-in light let you see when it is full without opening the unit.
On the downside, the Polaris VRXIQ+ carries a high price tag that may not fit every budget. It is also relatively heavy at 44 pounds, which can make lifting it out of the pool a two-person job. Additionally, the app features rely on a strong Wi-Fi signal; without it, some smart functions are limited.
Overall, the Polaris VRXIQ+ is a top-tier robotic cleaner that delivers on its promise of smart, efficient pool maintenance. If you have a large pool and value automation and remote control, this cleaner is an excellent investment. Its build quality and feature set justify the premium cost for serious pool owners.
Buying Guide
When choosing between the Polaris ERA 842 and ERA 820, consider these key factors to ensure you pick the right cleaner for your pool. Each criterion helps you match the cleaner’s capabilities to your specific pool size, shape, and debris load.
Smart Features and App Control
Smart connectivity transforms how you interact with your pool cleaner. The Polaris ERA 842 offers full app control via a smartphone, allowing you to schedule cleanings, start or stop cycles, select cleaning modes (Floor or Floor/Wall), and even initiate the Easy Lift removal system. You can also receive troubleshooting alerts and view the cycle timer, all from your phone.
In contrast, the ERA 820 operates with a simple plug-and-play design. You plug it in, press start, and it runs for 2.5 hours. While it lacks app integration, it’s incredibly straightforward for those who prefer a no-fuss approach. If you value convenience and remote control, the ERA 842 is the clear winner. If simplicity is your priority, the ERA 820 won’t disappoint.
Cleaning Power and Coverage
Both cleaners use Polaris’s Cyclonic Vacuum Technology to maintain strong suction and enhance wall climbing. The ERA 842 features front and back scrubbing brushes and dual-traction motors, which provide superior agitation to lift dirt and algae from pool surfaces. It’s designed to tackle any inground pool surface, from concrete to vinyl.
The ERA 820 also cleans floors and walls, but with a slightly less aggressive brush system. It’s still highly effective for regular maintenance and handles moderate debris well. For pools with heavy debris or stubborn grime, the ERA 842’s enhanced scrubbing action gives it an edge. For more on powerful cleaning, see our top Polaris EPIC 8520 alternatives.
Ease of Use and Maintenance
Removing the cleaner from the pool and emptying its debris canister should be hassle-free. The ERA 842 excels with its Easy Lift Removal System, which drives the cleaner to the waterline and drains water for lightweight lifting. Its large-capacity canister is easy to access, so you simply remove, shake, and spray it clean.
The ERA 820 also features a large 4-liter canister with a similar easy-access design. However, it lacks the automated lift feature, so you’ll need to manually pull it out, which is heavier when full. Both models include a premium caddy and cover for storage and transport, but the ERA 842’s automated removal is a significant convenience.
Cable Length and Maneuverability
The length of the power cable determines the range your cleaner can cover. The ERA 842 comes with a standard cable, but the exact length isn’t specified here; however, it’s designed for pools up to 50 feet. The ERA 820 includes a 60-foot cable with a tangle-reducing swivel, which is excellent for larger pools and prevents frustrating cord tangles.
Both cleaners are agile on pool surfaces, but the ERA 842’s dual-traction motors provide better climbing ability on steep walls and around obstacles. If your pool has a complex shape or a long distance from the outlet, the ERA 820’s longer cable is a practical advantage.

Final Thoughts
Choosing between the Polaris ERA 842 and ERA 820 ultimately comes down to your preference for smart technology versus simplicity. If you want app control, automated retrieval, and the most powerful cleaning action, the Polaris ERA 842 Smart Robotic Pool Cleaner, Corded is your best bet. For a more budget-friendly, plug-and-play option that still delivers excellent results, the Polaris ERA 820 Robotic Pool Cleaner, Corded is a reliable choice. Both are backed by Polaris’s 50-year legacy of quality, so you can trust either to keep your pool sparkling clean.
