POLARIS Vac-Sweep® 3900 Sport
1-year Polaris warranty
The cleaner; its frame is covered for 5 years. From the date of retail purchase. Frame: 5 years.
Polaris’s warranty termsProduct Overview
A proven choice for pools with heavy leaf loads, the Polaris 3900 Sport utilizes a stainless steel drive chain and triple-jet suction to handle debris that stalls standard cleaners.
The Polaris Vac-Sweep® 3900 Sport is a high-performance pressure-side cleaner featuring an all-wheel PosiDrive system and a wide 2.5-inch vacuum inlet. In our experience, the dual-chamber SuperBag and TailSweep Pro attachment make this model the standard specification for large in-ground pools requiring consistent wall climbing and heavy debris removal. It requires a dedicated booster pump to power its triple-jet Venturi system, ensuring high-torque movement across plaster, pebble, and vinyl surfaces.

The Polaris 3900 Sport pressure-side pool cleaner delivers powerful vacuum performance, efficient cleaning, and reliable operation for in-ground pools. Featuring an all-wheel PosiDrive system with a durable stainless steel drive chain, it provides enhanced torque for faster, more effective debris removal. Its dual-chamber zippered SuperBag captures more leaves, acorns, and small debris, reducing the need for frequent emptying while helping to protect the pool’s filtration system. Powered by a booster pump, the 3900 Sport connects to a dedicated return line for hassle-free cleaning. The in-line auto-reverse technology ensures continuous movement by freeing the cleaner if it gets stuck. Equipped with the TailSweep PRO®, it effectively clears debris from corners and hard-to-reach areas while preventing water from spraying outside the pool.

Most vacuum power of any 3-jet Polaris cleaner, with 40 GPM of additional pool filtration through the filter bag.
All-Wheel PosiDrive System
Enjoy a quicker clean and fewer hang-ups with 50% more torque and the All-Wheel PosiDrive system featuring a durable stainless-steel drive chain.
Hassle-Free Operation

The pressure-side cleaner we pick for heavy leaves.
The Polaris Vac-Sweep 3900 Sport (F6) is driven by a booster pump. Polaris gives it three venturi jets, a 2½-inch vacuum inlet and a dual-chamber SuperBag, and says it circulates an additional 40 gallons of filtered water a minute — for all in-ground pools.
3-Jet Vacuum
Polaris’s three-jet system and a 2½-inch vacuum inlet for large debris.
All-Wheel PosiDrive
A stainless-steel drive chain that Polaris says delivers 50% more torque, on WideTrax tires.
Dual-Chamber SuperBag
Collects and stores debris in its own bag, so it stays out of your pool’s filter. Polaris does not publish the bag’s fineness.
Auto Back-Up and TailSweep PRO
Auto-reverse for fewer hang-ups, and the TailSweep PRO sweep-hose tip (included) to clear corners without spraying water out of the pool, per Polaris.
What you’ll need
A booster pump (sold separately) — Polaris pairs the 3900 Sport with the PB4SQ. When you submit the purchase-assistance form we’ll check what is on your equipment pad; adding a booster where there is none is plumbing work.

Benefits & What Makes It Different
Triple-Jet Venturi Suction
Three powerful jets create a high-velocity vacuum that pulls in large leaves and acorns through a wide 2.5-inch inlet.
PosiDrive System
The stainless steel drive chain delivers 50% more torque than previous models, allowing the cleaner to navigate steep walls and deep ends without slipping.
Dual-Chamber SuperBag
The zippered 5-liter debris bag holds significantly more volume than standard bags, reducing the frequency of manual cleanouts during peak leaf season.
Compatibility
- Requires a dedicated booster pump
- Compatible with all in-ground pool surfaces
- Works with standard 1.5-inch threaded return lines
When To Use This
Pro Tip
Check the wheel RPMs regularly; if the cleaner is moving too slow or too fast, adjust the pressure at the wall fitting to ensure the drive chain maintains optimal torque for wall climbing.
Common Questions & Instructions
Does the Polaris 3900 Sport require a booster pump for operation?
Yes, this pressure-side cleaner requires a dedicated booster pump, such as the PB4-60, to provide the necessary water pressure for the Venturi jets and the PosiDrive system.
What types of pool surfaces is the Polaris 3900 Sport compatible with?
The 3900 Sport is designed for all in-ground pool surfaces, including plaster, pebble, quartz, vinyl, and fiberglass, providing safe and effective cleaning without scuffing.
How does the TailSweep Pro attachment improve pool cleaning?
The TailSweep Pro prevents the sweep hose from spraying water outside the pool or onto windows while increasing the sweeping action to move debris out of tight corners.
