Polaris 3900 Sport pool cleaner integrated with advanced features compared to Polaris P39; hence, I strongly recommend this cleaner. Also, for your consideration, I’ve described the details here.

Why do I recommend Polaris 3900?

  • Polaris 3900 Sport has a PB4-60 Booster Pump that increases the suction power to clean more prominently. But P39 doesn’t include the pump; if you want to use it, you must purchase it separately.
  • All-Wheel PosiDrive with Stainless Steel Chain of Polaris 3900 creates 50% more torque to help the machine get itself out of anything if it gets stuck. In contrast, Polaris P39 doesn’t support it.
  • It provides a dual-chamber debris bag, including a scrubber bag. The filter bag will capture everything and won’t get stuck in the wheels. Simultaneously, Polaris P39’s bag keeps getting stuck in the wheels and stops running. That’s why you have to pull out the machine every hour to remove the bag from the wheels.
  • The machine ensures you scrub, vacuuming everything in between, but P39’s foam scrubber doesn’t scrub the pool properly.
  • Polaris 3900 Sport will clean the steps effectively while P39 cannot clean the steps, which is a downside.

Hopefully, now you get all your answers to why Polaris 3900 Sport is a better choice. If you have a large pool plus want to clean it effectively, the 3900 Sport should be your choice.

Features and Benefits of Polaris P39 and 3900

Suction Power 

Polaris pool cleaners beat all machines in terms of suction power since they use advanced technology. The P39 and 3900 Sport are powered by three jets that provide the most vacuum power. Also, they produce the maximum vacuum power with their stainless steel drive chain mechanism system. It maximizes the speed plus offers the best performance compared to other pool cleaners on the market.

Filter Bag 

The machines include TailSweep Pro, an advanced hose enhancement to blow the debris out of the hard places in the pool that reaches tough. Furthermore, Polaris P39 and 3900 Sport come with a dual-chamber debris bag, including a scrubbing bag. So during the filtration process or cleaning the pool, they will effectively pick the largest debris.

But the P39 cannot properly do the debris cleaning job because the debris bag of the P39 tends to get stuck with the wheels. And the machine cannot pull out the bag from the wheels, so you need to remove the machine from the pool every hour to remove the bag. That’s why the 3900 Sport would be the best option, since the bag won’t get stucks to the wheels and it will take less than three hours to clean.


As I mentioned earlier, Polaris P39 and the 3900 Sport are the same in terms of design; only their size and weight are different. Both of them are built with the latest cleaning technology. They feature 3-jets. They are compatible with the TailSweep Pro, which offers the ultimate sweeping action by reducing the water spray.

Drive Mechanism 

They combine with the all-wheel PosiDrive system that is built with a stainless steel chain. The mechanism creates 50 percent torque to maximize the cleaning performance and ensure fewer hang-ups. The drive mechanism of the Polaris pool cleaners ensures durability and reliability.

Pool Surface 

Polaris will effectively clean every surface if you have a vinyl pool surface, tile, concrete, or whatever the surface is. They are designed to clean any surface; also, the machines can clean and scrub saltwater. So, don’t worry about the pool surface until you have an in-ground pool. But don’t use them for the above-ground pools, or the machine will tear your pool.


Polaris P39 and 3900 have the same goodies in the box; provide them to ensure you can start using the machine once you get it at home. However, you will get the Pool cleaner itself, a 31-foot hose, a backup valve, and the operating instructions.


Polaris P39 and 3900 Sport have a fantastic deal; generally, they offer a two-year warranty on their products. But you can also extend it up to three years, and you’ve to pay some extra bucks. Furthermore, the Polaris gives you a two-year warranty on the booster pump and three years on the pool pumps; the pool filter comes with three years of convenient warranty. You can claim the warranty if you have a defective product or the product shows any mechanical issue. Contact the Polaris website, or you can call or send them a mail.


Polaris 3900 Sport features advanced cleaning technology to help you up to your cleaning game. This is a fantastic pool cleaner since it is equipped with the best suction power and will scrub and vacuum the steps to everything to ensure you are better clean.

On the other hand, the Polaris P39 cannot do those things for you. Also, the 3900 Sport will take less than 3 hours to clean the pool entirely, but the P39 will take more than 3 hours. I highly recommend you to go with the Polaris 3900 Sport if you are serious about a pool cleaner.
