  • Extremely powerful cleaner
  • Large debris bag
  • 4 wheel drive improves stability
  • Great pool coverage in short time

Things We Didn't Like

  • Requires booster pump - purchased separately
  • Doesn't clean step areas of pool



It comes with a big, two-chambered zipper bag that collects a significantly larger amount of waste and debris, making clean-up a lot faster and more efficient.

One reason why this cleaner is so highly rated is for its stable four-wheel base and the stainless steel drive chain. If your pool has large debris that could benefit from being filtered, this might be the ideal solution for you.

The Polaris Vac-Sweep 3900 has a 3-jet cleaner through its filtration bag that circulates at 40 GPM reducing the amount of wear and tear that could have occurred as well as supporting your skimmer in keeping the pool free of bacteria.

It is sold with other accessories to make your cleaning experience pleasant such as an all-purpose zipper superbag for collecting a larger amount of debris, sweep hose scrubber, WideTrax tires and a black silt bag.


The Polaris 3900 Sport is a pressure-side cleaner with three venturi jets that help maximize its vacuum power

It is designed to work in all in-ground pool surfaces. It features a detachable dual-chambered zippered super bag that collects and filters both large sized debris and a greater percentage of waste and debris.

The 3900 pool cleaner features a PosiDrive system that generates 50% more torque which significantly increases the performance and speed of the cleaner.

Polaris Sport Profile

The 3900 features an advanced sweep hose called the TailSweep Pro that thoroughly cleans out debris from hidden corners of the pool and prevents water from splashing outside the pool while cleaning.

The pressure-side cleaner includes a new auto-reverse technology that prevents it from getting stuck and allows it to back out of tight corners; it also changes the cleaners direction and cleaning pattern a little better than the Kreepy Krauly Racer.

The Pressure cleaner has four wheel which gives it traction and stability as its cut through the pool and climbs the wall surfaces of the pool unlike the Vacsweep 65.

The Polaris 3900 Pool Cleaner requires a booster pump to function, which is not a big deal if you have ever used a pressure side cleaner before. We recommend the PB4-60 booster pump which if combined with the3900 Sport would result in maximum performance and efficiency.

It is a powerful unit that has a lot of praises for its dependability and speed of cleaning. This cleaner circulates an additional 40 gallons per minute through its filter bag to aid the circulation and filtration system of the pool.

A significant improvement with the Polaris 3900 Sport Pool Cleaner to its predecessor is the TailSweep Pro. This is the tail that wags back and forth behind the cleaner sweeping the floor and walls as the machine moves by.

What we had in the past was a tail that did more splashing than cleaning, but the new ones won't spray water out of the pool even when it comes to the surface of the water, and it can fit any pressure-side Polaris cleaner.

Ease of Use

The Polaris 3900 Sport Pool Cleaner is easy to use, easy to operate and to install. To install the Polaris, follow the instructions stated in the manual to trim the hose to the length you require, to regulate the water pressure to get optimal suction, vac pattern, speed, and tailsweep.

Polaris Sport Close Up

It comes with just one debris bag, if you need an extra one, you will have to purchase it. The cleaning cycle of the pressure cleaner is quite fast, and it cleans effectively.

There are a lot of interesting things about the Polaris Vac 3900.

First, it requires a booster pump to power it up so you can't run it on your existing backup line.

Second, due to the strength of the Venturi Jets, the filtration bag might fill up quicker than normal which means you would have to empty it frequently than you would have loved to.

Having this pressure cleaner work with a bag that is too heavy is not ideal, and it could prevent it from working or moving as fast as it should.

Who is this meant for?

This pressure side cleaner is suitable for inground pool owners who don't mind sparing the cost of getting their pools cleaned as quickly as possible without having to spend time monitoring the cleaner as it goes by.

It's a very powerful cleaner, and its selling points are the speed of movement and cleaning due to the WideTrax tires and the TailSweep Pro as well as the power which it uses to circulate and filter additional water during its cycle.

Polaris 3900 Sport Pool Cleaner Review: Conclusion

The Polaris 3900 Sport Pool Cleaner is an exceptional product that delivers maximum performance. Despite its high price tag, it is a quality unit, and it is worth every penny.

While it has its advantages, keep in mind that it requires a booster pump every time you need to use (sold separately) and it won't clean your step areas. We don't consider these as deal breakers for a product as dependable and robust as the Polaris Sweep 3900 and we recommend this here at Ultimate Pool Guide
