There are tons of automatic pool cleaning devices out there, from the high-end Dolphin line to the affordable-yet-simple Hayward Poolvergnuegen. Today, we’re going to take a gander at the Polaris Vac-Sweep 3900 Sport—a pressure side pool cleaner that, if you go by reviews, doesn’t seem to be too promising.
However, we’re here to dispel any rumors you may have heard or read. The Polaris Vac-Sweep 3900 is a definite game-changer.
Reliable Cleaning Performance
The 3900 may be a simple robot, at least compared to the likes of the Maytronics Dolphin series, but when it comes to keeping your in-ground pools clean, it doesn’t miss a beat. This pressure side pool cleaner works by randomly navigating your pool and suctioning small, medium, and large debris.
This pool cleaner employs the use of three Venturi-style jets to take in, filter, and pass an astounding 40 gallons of water every minute. The 2-1/2-inch wide mouth takes in anything it comes across, from algae to fallen leaves to even large-sized acorns.
Among the numerous pressure pool side cleaner options, you’ll have a difficult time finding one more powerful than this.
Using this pressure side pool cleaner requires the use of a booster pump. Unless you have one on hand, you’ll be unable to operate this beast of a cleaner.
This, unfortunately, means shelling out a couple hundred bucks on an entirely different tool.
TailSweep PRO Technology
The awkward shape of the 3900 makes it unable to fit in corners. If you have a rounded or sloped pool, then it wouldn’t matter, but for most pool owners out there, corners are where the majority of the mess is located. However, despite its design, the 3900 is still capable of cleaning all four sides and corners thanks to the TailSweep PRO.
The snap-on feature is a scrubber/hose combo that shoots high-pressure jets of water at corners to push debris into a reachable spot for its suction vacuum. Best of all, this hose doesn’t blast water upward and out of your pool.
PostiTrain 3WD Movement System
The 3900 gets around on three wheels that are driven by hydraulics which take water from the booster pump to turn the wheels. Don’t be concerned about the chain linking the wheels and gearbox—its made out of stainless steel to withstand corrosion throughout the robot’s entire lifespan.
The wheels covered in Widetrax tires with to provide better traction for scaling walls and ramps. Eventually, you’ll need to swap the three tires out for a new set, and concrete pools will wear the tires out quicker.
Random yet Effective Navigation
The 3900 isn’t has high-tech as what you’d find in Maytronic’s line of Dolphins, but it definitely knows how to get around. The oversized wheels allow it to travel freely in all types of pool surfaces, and if/when it gets stuck in underwater obstacles, the 3900 is programmed to back up a few paces to free itself before continuing its cleaning job.
Polaris has thrown in a 1-1/2-inch feed hose that connects the 3900 to the pool’s return line. It’s essentially a connect-and-go sort of bot that requires no special tools or skills to operate.
The hose measures in at 31 feet long, providing complete freedom of movement underwater in in-ground pools of up to 25 feet or so. If your pools are shorter, feel free to snip off any unneeded length.
5-liter Double-Chamber Bag
One thing that customers rave about is the 3900’s humungous 5-liter debris collection bag. Unzip the bag and you’ll find twin chambers where different sized debris is stored. This setup extends the lifespan of the filter bag to an entire year, reducing the frequency of purchasing replacements.
The only trouble most people have with the dual-chamber bag is that when dirt gets caught in the zipper’ teeth, it can be an absolutely pain to open.
Verdict: Should I Get the Polaris Vac-Sweep 3900 Sport Pressure Side Pool Cleaner?
The Polaris Vac-Sweep 3900 Sport Pressure Side Pool Cleaner is somewhat a mixture between the basic Hayward Poolvergnuegen and most Dolphin robotic pool cleaners. So if you don’t have the budget for a Dolphin but you’re also in need of something a little more reliable than the Hayward, this is may be your best option.
Performance-wise, there are absolutely no complaints coming from us, but we can definitely understand why the need to purchase a booster pump can push people away. Overall, it’s a reliable pressure side pool cleaner that doesn’t disappoint in the slightest.
