The Polaris F9550 is a robotic pool cleaner that combines all of the features you’d ever want and need. Backed by state-of-the-art artificial intelligence and mapping tech, virtually everything this robot can do can be programmed into its scheduler. But like all modern robotic pool cleaners, the F9550 isn’t perfect, as you’ll see as you read my full review.

4WD Technology

In most modern robotic pool cleaners, you’ll find that they come with tracks to help ease them along the slippery base and walls of your pool.

Not the F9500 – this compact robot sits atop four oversized tires, all of which spin, that move your robot to wherever its logarithm dictates. Tracks are arguably the better travel option, but tires, especially these anti-slip Aqua-Trax tires, are no reason to complain.

70-foot Non-Tangle Power Cord

Do you know what makes Maytronics robots so great? Other than unparalleled cleaning performance, the non-tangle power cord is what lends their robots – the F9550 included – maximum, hassle-free mobility underwater.

They’re free to move about the base and walls of your pool without risk of choking itself or wrecking the power cord in the process. The cord’s length makes the F9550 suitable for in-ground pools of up to 60 feet.

ActivMotion Sensor

The major reason why anyone would consider investing in a robotic pool cleaner is freedom. ActivMotion Sensor technology has surpassed previous navigation software by a wide margin, offering the best control and programmable features.

ActivMotion creates a digital layout of your pools home with the help of multiple sensors in order to create the most efficient cleaning path. Essentially, it spends less time underwater while still touching most areas of your pool.

Motion-Sensing RC

I’d love to tell you that the F9550 will be able to leave your pool absolutely spotless, but that’s not the case. Every robot has its faults, and in the case of this model, the navigation system may be the problem.

Luckily, you can manually control the robot to go to areas it may have missed. The controls are a bit clunky but it definitely beats manually moving the robot to dirt-filled areas.

Canister Indicator

Depending on how dirty your pools are, the top-loaded filter canister can reach maximum capacity in no time at all. Good thing the F9550 has a canister indicator that alerts its users when the filter is full.

To empty it out, simply open the latch on top of the robot, pull the canister out, and give it a few quick shakes to dump the contents. Reinstalling the canister is just as easy – just pop it in and you’re all set.

Vortex Vacuum

The F9550 doesn’t just scrape up pool gunk with its active brushroll – the vortex vacuum creates a miniature cyclone that agitates the water, knocking loose debris off the base and walls of your pool for the robot to suction up. Suspended debris is a lot easier for the robot to suction than trying to pull it off the lining of your pool.

Programmable up to 7 Days

Setting up and watching the F9550 can lose its fun over time, which is why I’m glad to see that this robot has a 7-day programmable scheduler.

All you need to do is set the cleaning schedule for every day of the week, leave the F9550 in the base of your pool, and you’re done. Even if you forget to clean your pool, the F9550 won’t. Ever.

Waterline Only Mode

One handy feature is the Waterline Only cleaning mode which, as the name suggests, sends the robot to clean the waterline of your pool.

It uses jets of water to propel itself vertically in order for the scrubs to reach the waterline and remove algae, leaves, and other pool gunk from view. Considering the waterline collects the most debris, you’ll definitely want to use this feature quite often.

Not the Best for Pool Stairs

The one area where robotic pool cleaners tend to miss the most is pool steps, and the F9550 is no exception. Indeed, it can propel itself vertically, but the sudden change of surface terrain on steps can cause the unit to topple over.

This means you’ll have to fish it out and put it right-side up every so often.


Many customers have praised the Polaris F9550 for its ease of use, cleaning performance, and unique waterline-only cleaning mode. Considering it has very few downsides, is worth every penny.

Cleaning 60-foot long pools is no mean task, but if you have the F9550 at your side, the only time you’ll need to whip out the pool scraper and net is when cleaning pool stairs. For everything else, just let the F9550 do its thing.
