You’ve just spent a sunny afternoon staring at a dull film of pollen and grass clippings floating on your pool’s surface. The thought of dragging out the old pressure-side cleaner, untangling hoses, and wrestling with the pump’s filter basket feels like a chore you’d rather avoid. That’s exactly why robotic pool cleaners have become the go‑to solution for pool owners who want more swim time and less maintenance time. In this guide, we’re focusing on two standout models from Polaris: the Polaris ERA 842 Smart Robotic Pool Cleaner, Corded and the Polaris ERA 820 Robotic Pool Cleaner, Corded. Whether you’re upgrading from an older model or buying your first robotic cleaner, this review will help you decide which one matches your pool size, cleaning habits, and budget. We’ll also share a few insights from our Polaris pool cleaner guides to give you a broader perspective.
Both the ERA 820 and ERA 842 are corded, meaning they plug into a standard outlet and run on a long cable, which is ideal for pools up to 50 feet. They share the same core DNA: powerful cyclonic suction, dual scrubbing brushes, and a large debris canister. But the ERA 842 adds a layer of convenience with its smart app control and an automatic lift‑and‑drain system. Let’s break down what each model brings to the table so you can pick the one that fits your lifestyle.
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: What to Look for in a Polaris ERA Series Cleaner
Choosing between the ERA 820 and ERA 842 isn’t just about price. It’s about matching the cleaner’s features to your pool’s specific needs. Here are the key factors we evaluated in our Polaris cleaner comparisons to help you decide.
Pool Size and Cable Length
The cable length determines how far the cleaner can travel from the outlet. Both models come with a 60‑foot cable, which is perfect for pools up to 50 feet long. If your pool is larger, you might need an additional extension or a different model. Measure your pool’s length and the distance from the nearest outlet to the water’s edge before purchasing.
For most residential inground pools, the 60‑foot cable offers plenty of reach. The low‑torque swivel on both models reduces tangling, so the cleaner won’t get stuck in a knot mid‑cycle. This is a huge time‑saver, especially if you have a complex pool shape with steps or a sun shelf.
Cleaning Modes and App Control
If you love the idea of starting your pool cleaner from the couch or while you’re at work, the ERA 842’s smart app control is a game‑changer. You can schedule cleanings, choose between floor‑only or floor‑and‑wall modes, and even trigger the Easy Lift removal system remotely. The ERA 820, on the other hand, is strictly plug‑and‑play: press start, and it runs a full 2.5‑hour cycle covering both floor and walls.
For tech‑savvy pool owners, the app adds a layer of convenience that justifies the higher price of the ERA 842. But if you prefer a no‑fuss, set‑and‑forget approach, the ERA 820’s simplicity is equally effective. Consider how much you value remote control and scheduling before making your choice.
Ease of Maintenance and Removal
Nobody wants to wrestle a dripping, heavy cleaner out of the pool after every session. The ERA 842 features an Easy Lift Removal System that drives the cleaner to the waterline, drains the water, and makes lifting it out a one‑handed task. The ERA 820 requires you to pull it out manually, which is fine but less convenient.
Both models have a large 4‑liter debris canister that you can empty quickly by simply removing, shaking, and spraying it. This design minimizes contact with dirt and debris, keeping your hands clean. If you have a large pool or lots of leaves, the bigger canister means fewer emptying sessions.
Wall Climbing and Scrubbing Power
Both the ERA 820 and ERA 842 use Polaris’s Cyclonic Vacuum Technology to maintain strong suction and climb walls effectively. The dual‑traction motors in the ERA 842 provide extra grip on slippery surfaces, making it a better choice for pools with textured or tiled walls. The front and back scrubbing brushes work together to dislodge stubborn algae and grime.
If your pool walls tend to develop a slippery film, the ERA 842’s enhanced climbing ability is worth the extra investment. For pools with smooth plaster or vinyl, the ERA 820’s suction is more than adequate. Think about the surface material of your pool and how much scrubbing action you need.
Final Thoughts
Choosing between the Polaris ERA 820 and ERA 842 ultimately comes down to your priorities: if you value smart features, remote scheduling, and effortless removal, the Polaris ERA 842 Smart Robotic Pool Cleaner, Corded is the upgrade that makes pool maintenance feel like a luxury, while the Polaris ERA 820 Robotic Pool Cleaner, Corded delivers reliable, powerful cleaning for those who prefer simplicity and value. Both are built with Polaris’s legendary durability and come with the peace of mind of a trusted brand, so you can’t go wrong either way.
