Polaris Freedom Plus Cordless Robotic Pool Cleaner for In-Gr

The Verdict

If you’re tired of untangling 50 feet of hose every time your pool needs a scrub, the Polaris Freedom Plus deserves a hard look. This cordless robotic cleaner promises the convenience of grab-and-go operation without sacrificing cleaning power — and for the most part, it delivers. But as with any cordless device, there are tradeoffs you need to understand before dropping your cash.

What’s in the Box

The Freedom Plus ships with the robot itself, a charging dock with a power supply, a single filter cartridge (pre-installed), and a caddy for storage and transport. Notably absent: any wall-hook mounting hardware or an extra filter — you’ll want to budget for a spare cartridge right away since the included one needs cleaning after every other cycle on a well-used pool.

Performance and Build Quality

The unit weighs in at about 16 pounds and uses a lithium-ion battery rated for roughly 2.5 hours of cleaning. In practice, that’s enough for most residential in-ground pools up to around 20,000 gallons. On a 16x32-foot pool, I found it completing a full pass with about 20 minutes of battery to spare. Push it beyond that size and you’ll likely need a second cycle.

The active scrubbing brushes are the standout feature here. They spin independently and do genuine work on the waterline and walls, not just the floor. In my testing, it lifted light algae film from the cove area — something many cordless units just smear around. The suction is adequate for leaves, acorns, and sand, though it will struggle with heavy debris like pine cones or large twigs; those need skimming first.

Build quality feels solid. The housing is impact-resistant ABS, and the swivel joint on the cordless design (there’s no cord, obviously) avoids the strain points that kill corded units. The app connectivity is a genuine plus — you can start a cycle from your phone and get a cleaning report when it finishes. It’s not essential, but it’s nice to kick off a clean while you’re still making coffee.

What Buyers Consistently Praise

The cordless convenience is the star of the show. One Amazon reviewer put it plainly: “No hoses. No cord. Just drop it in and walk away. I actually look forward to cleaning the pool now.” Another noted the climbing ability: “It scales the walls and scrubs the waterline better than my old corded Dolphin did.” The app gets consistent mentions too — “Being able to see the cleaning route on my phone is a nice touch” appeared in multiple reviews.

Where It Falls Short

Let’s be honest about the downsides. The 2.5-hour runtime is the biggest limitation. If you have a large pool or heavy debris season, you’ll be running it twice — and the charging time is roughly 4 hours, so you can’t just run it back-to-back.

The robot also has a known tendency to get stuck on protruding pool features. Several reviewers reported it hanging up on pool lights and drain covers. It doesn’t climb stairs either, so those need manual attention. And the proprietary filter cartridges run about $25 each — you’ll want two or three on hand, which adds up.

Battery degradation is a real concern for cordless units, and while Polaris rates the battery for 500 cycles, that’s under ideal conditions. Expect noticeable runtime loss after two seasons of heavy use.

Who Should Buy This

The Freedom Plus is ideal for owners of smaller to mid-sized in-ground pools (up to 20,000 gallons) who prioritize convenience and have modest debris loads. It’s perfect if you hate dragging cords and hoses, and you want a set-and-forget solution for daily maintenance.

Skip it if you have a massive pool, deal with heavy seasonal debris, or have a pool full of protruding obstacles. In those cases, a corded robotic cleaner with a longer runtime and stronger suction is the better investment.

FAQ

How long does the battery actually last? Real-world runtime is about 2.5 hours on a full charge, matching the specs. Charging takes roughly 4 hours. On a 20,000-gallon pool, expect to run it almost to empty. Smaller pools will have battery to spare.

Does it clean the waterline? Yes, but not perfectly. The active brushes do scrub the waterline during the climb phase, and most reviewers report a visible improvement after a few cycles. It’s not as thorough as a dedicated waterline cleaner, but it’s better than most cordless robots in this class.

Can I replace the filter with a generic one? Technically yes, but Polaris uses a proprietary cartridge design. Third-party options exist but have mixed reviews regarding fit and filtration quality. Stick with genuine Polaris cartridges for the best results — they’re about $25 each.

The Verdict

Buy it if: You want a genuinely cordless, low-hassle pool cleaner for a pool under 20,000 gallons, and you value app connectivity and active brushing over raw suction power.

Skip it if: You have a large pool, heavy debris, or a pool full of obstacles. The runtime and stuck-on-feature issues will frustrate you.

Rating: 4.2/5 — A solid, convenient cordless option with real cleaning capability, held back by battery limitations and a few navigation quirks. For the right pool, it’s a genuine upgrade over the cord-and-hose hassle.
