Massive Top-Loading NanoFilter™ MaxBin™

The Quantum includes the largest MaxBin™ Ever. In addition to the included standard fine filter, Quantum introduces the next generation NanoFilter™ in a massive 400 square foot easy to clean basket configuration. This micro-pore spun-bonded polyester creates a tight structure that traps even the smallest micron particles. Quantum’s next gen filtration has a much larger surface area, capturing more waterborne particles while maintaining low resistance. Most filters capture leaves and large particles but Quantum stops pollen, algae, bacteria, pet dander, and other microscopic debris in their tracks. The increased pleated surface area keeps cleaning for up to a week, handling a higher volume of contaminants.

NanoFilters™ capture fine dirt and debris that passes through the standard filters

The NanoFilter™ Difference

The Nanofilter high-efficiency particulate filter prevents contaminants from recirculating in water you swim in. Nanofilters are the only filter capable of removing oil. When oil is caught in Nanofilter, it forms a transparent sheath over the trapped debris. This mixture is removed at cleaning, providing a valuable method to improve turbidity and improve the transparency of the water. Pleated Nanofilters deliver a higher level of filtration for crystal clear and polished water. The common cloudy appearance of pool water caused by small suspended particles is no match for Nanofiltration. Try Quantum for 30 days and you’ll see the difference.

Powered by PowerJet 3D Mobility™

Long suggested to be part of the ultimate in underwater robot mobility, Power Jet 3D™ Mobility is now available in a pool-cleaning robot. Patent-Pending multi-direction water flow provides constant grip on vertical surface for superior wall and tile line cleaning. The Quantum employs three jet nozzles capable of creating vectored thrust to deliver a range of motion that is impossible with ordinary pool robots. As the robot climbs the wall, the three jet nozzles create a powerful force as a stream of fast-moving water is expelled in up to three directions.

PowerJet Mobility provides the robot with precise control that allows it to move at extreme angles and even laterally on the wall. Water-jet drive provides a major advantage when compared to conventional pool cleaners. Jet drive steers the robot with vectored thrust, providing unmatched maneuverability , including the ability to precisely hold a robot in a fixed position against the effects of gravity. The Quantum is the world’s first pool robot propelled by three jet drives with thrust vector control for ultimate maneuverability. Power Jet 3D Mobility also improves navigation accuracy and enables the robot to escape and avoid any obstacle.

Oversized Filter MaxBin

Easy-to-clean SnapLoc™ Filtration

Stop wasting valuable time cleaning your robot. Cartridge filters have been around for years, but early adopters found it difficult to scrape out dirt and debris. Consider this problem solved. All four sides of the Quantum filter are removable for quick and easy cleaning. In addition, the bottom panel is hinged to allow released debris to simply fall out.

SmartNav 2.0 Robotic Scanning

SmartNav 2.0™ Scanning Software

Overall Rating: 4.7

Lance Hansman - 5 Stars

Was the best thing you can buy for your pool. Drop in pool and watch clean. Pool in is brushed and vacuumed to perfection.

Jack Faessler - 5 Stars

The cleanliness of my pool has been greatly improved, and the amount of time that I must expend to maintain a clean pool has been minimized. Yours is an outstanding product: works as is demonstrated. It is in daily use here. Its ONLY detractor is the tendency for its power cord to tangle/kink with repeated use —which requires periodic manual detachment from the control unit, straightening it's cord and reattachment. A retrofit for that would be appreciated!

Miquel Abramowicz - 5 Stars

From the moment I unwrapped it I knew I'd love it. What impressed me the most was the filter baskets, with its removable sides. Compared to my old Dolphin, that used a bag, the I had to empty, wash and scrub, what a laborious pain it was. If I had to mention a deficiency, I'd list the fact that the clean cycle is too short, perhaps there's a longer cycle, that I'm unaware of. I did experience a problem with the filter panels, that started disintegrating about a year after I got, When I contacted Maytronics, they offered to replace them as a one time courtesy Kudos to them!

Pat J. - 5 Stars

I've had my Dolphin Quantum for a year now and absolutely love it. I run it year-round since I live in Florida. It performs beautifully and keeps the pool sparking clean. The only problem I have is that the cord attached to the robot doesn't swivel and you get a knotted, tangled mess. Otherwise it is a great investment.

Allan L - 5 Stars

Let leaves pileup for a week, amazing, picked up 95% very satisfied. Dolphin Quantum is a amazing bot.
