As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You might be researching polaris era 842 smart robotic alternatives to find the right cleaner for your pool setup. The Polaris ERA 842 cleans inground pool floors and walls using dual scrubbing brushes, dual-traction motors, and cyclonic suction. Its smartphone app allows you to set schedules, view cycle timers, choose cleaning modes, and run the Easy Lift retrieval system. It also includes a transport caddy and cover. You might still want a different option if you prefer a cordless battery design instead of a corded connection. You may also want dedicated waterline scrubbing, different physical dimensions, or a different brand.
The 6 alternatives on this list were chosen because their specifications overlap with the original cleaner. Each model handles inground pool cleaning and provides motorized scrubbing with app or Wi-Fi connectivity. Options include cordless models from AIPER and Beatbot, as well as corded Wi-Fi units from Dolphin. These alternatives allow you to compare power sources, dimensions, and navigation features to match your exact pool maintenance needs.
Our top pick: Polaris ERA Corded Robotic Pool Cleaner.
Comparing Polaris ERA 842 Alternatives
Aiper Cordless AI Vision Robotic Pool Cleaner
The Aiper Cordless AI Vision pool cleaner operates without a cord, delivering up to four hours of run time. It cleans floors, walls, and waterlines using visual debris navigation and multi-layer filtration. In contrast, the Polaris ERA 842 uses a corded connection and cleans only pool floors and walls. Choosing the Aiper frees you from power cords and adds waterline cleaning. However, you give up the continuous runtime of corded power, along with the Polaris Easy Lift retrieval system, included transport caddy, and protective cover. Pick the Aiper if you prefer a cable-free cleaner with waterline coverage and visual navigation over a corded machine with bundled transport accessories.
Beatbot Sora Cordless Pool Cleaner
The Beatbot Sora Cordless Pool Cleaner operates untethered with multi-hour battery life and 6,800 GPH suction power. It targets pool surface and floor cleaning, eliminating floating power cords. Compared to the Polaris ERA 842, the Beatbot cleans the pool surface, which the Polaris does not support. However, you give up wall climbing, dual scrubbing brushes, and smartphone app control with features like Easy Lift retrieval and scheduling. You also lose the included transport caddy and protective cover that ship with the Polaris. Pick the Beatbot Sora if you prioritize high-suction cordless surface and floor clearing over app-controlled wall scrubbing and corded endurance.
Dolphin Nautilus CC Supreme Wi-Fi Pool Cleaner
The Dolphin Nautilus CC Supreme features Wi-Fi connectivity, Dual Drive steering, and an active brush designed for wall and waterline scrubbing in pools up to 50 feet. It cleans higher than the Polaris ERA 842 by scrubbing all the way to the waterline. However, at 24.6 pounds and measuring 20 inches in each dimension, it is larger and heavier than the 16 by 17-inch Polaris. You also miss out on the Polaris Easy Lift waterline retrieval system, along with the included transport caddy and protective cover. Choose the Nautilus CC Supreme if you want dedicated waterline scrubbing and Wi-Fi scheduling for a large pool basin.
Dolphin Proteus DX5i Wi-Fi Pool Cleaner
The Dolphin Proteus DX5i provides automated wall and waterline scrubbing with Wi-Fi connectivity and a top-access filter basket. It expands cleaning reach to the waterline, whereas the Polaris ERA 842 restricts its coverage to pool floors and walls. At 17.4 pounds, the Proteus DX5i is a manageable machine, but at 22.2 inches in length, it is longer than the 17-inch Polaris. Choosing the Proteus means giving up the Polaris Easy Lift retrieval feature, cyclonic suction canister, and the included transport caddy and protective cover. Pick the Dolphin Proteus DX5i if you want connected waterline maintenance and a top-loading basket rather than floor-and-wall cleaning with bundled transport accessories.
AIPER Cordless Pool Cleaner and Solar Skimmer Duo
The AIPER Cordless Cleaner and Solar Skimmer Duo pairs a cordless floor vacuum with an autonomous solar skimmer to filter debris down to 3 microns across both the bottom and the water surface. This setup removes surface debris and eliminates power cables entirely, unlike the corded Polaris ERA 842. However, the AIPER duo does not provide the wall-scrubbing capabilities found on the Polaris, nor does it include the caddy, protective cover, or app-driven Easy Lift water evacuation system. Pick this AIPER duo if you need simultaneous surface skimming and fine 3-micron floor filtration without managing a power cable in your pool.
Dolphin Explorer Wi-Fi Pool Cleaner
The Dolphin Explorer E40 delivers Wi-Fi scheduling, Dual Drive steering, and active waterline scrubbing for in-ground pools up to 50 feet. It climbs all the way up to clean the waterline, exceeding the floor and wall coverage of the Polaris ERA 842. However, the Dolphin Explorer weighs 40.2 pounds, making it significantly heavier to lift out of the water than the compact Polaris. It also lacks the Polaris Easy Lift system that drives the cleaner up and drains water automatically, and it does not come with a caddy or storage cover. Pick the Explorer E40 if you want dedicated waterline scrubbing and do not mind lifting a heavier unit.

Frequently asked questions
Which Polaris ERA 842 alternative provides surface skimming in addition to floor cleaning?
The AIPER Cordless Pool Cleaner and Solar Skimmer Duo provides surface skimming alongside bottom cleaning. This setup pairs an autonomous solar skimmer with a vision-guided floor unit to collect floating waste and bottom sediment. It filters particles down to 3 microns without requiring power cords across your deck.
Are there lighter robotic pool cleaners than the Dolphin Explorer E40?
Yes, several alternatives weigh significantly less than the 40.2-pound Dolphin Explorer E40. The Dolphin Proteus DX5i weighs 17.4 pounds, making it easier to lift out of the water. Another option is the Beatbot Sora Cordless Pool Cleaner, which weighs 22.9 pounds, while the Dolphin Nautilus CC Supreme weighs 24.6 pounds.
Which alternatives offer Wi-Fi connectivity for scheduling cleaning sessions?
The Dolphin Nautilus CC Supreme, Dolphin Proteus DX5i, and Dolphin Explorer E40 all include Wi-Fi connectivity. This feature lets you program cleaning schedules remotely from your smart device. Each of these three models is designed for in-ground pools and targets wall climbing and dedicated waterline scrubbing during automated cycles.
What suction rate does the Beatbot Sora cordless pool cleaner deliver?
The Beatbot Sora Cordless Pool Cleaner delivers a suction rating of 6,800 GPH. This untethered cleaner runs on multi-hour battery life to maintain large pool basins. Its design addresses both pool surfaces and floor areas without managing a floating power cord, measuring 11.2 inches wide, 17.1 inches high, and 16.9 inches long.
Which alternative includes an easy-access filter basket for quick maintenance?
The Dolphin Proteus DX5i features a top-access filter basket that simplifies routine maintenance. You can remove and empty collected debris directly from the top lid rather than turning the machine upside down. This multi-colored robot also incorporates wall-climbing capability and Wi-Fi scheduling for standard in-ground pool basins.
How large of a pool can the Dolphin Nautilus CC Supreme clean?
The Dolphin Nautilus CC Supreme is rated for in-ground pools up to 50 feet. It utilizes Dual Drive steering and active brushes to clean walls and waterlines effectively. The unit measures 20 inches in width, height, and length, providing scheduled maintenance cycles through its built-in Wi-Fi connection.
What should you consider when choosing between corded and cordless pool robots?
Corded models like the Polaris ERA and Dolphin units draw continuous power from an outlet, avoiding battery recharges during deep cleaning sessions. Cordless models like the AIPER N31 Azure and Beatbot Sora rely on internal battery packs, eliminating floating cables around your deck but requiring recharging between cleaning cycles.
