Its optimized pump‑to‑jet design ensures quieter, more energy‑efficient operation while giving you complete control over your spa experience.
Vector21’s V3 Controls give you industry-leading command over water flow and massage, letting you direct power and pressure to each seat exactly how you want for a fully personalized spa experience.
Designed for ultimate customization, the Vector21’s interchangeable Jetpods—Conal, Directional, and Orbital—let you target massage styles from deep‑tissue to Swedish or Shiatsu, and can be easily swapped or upgraded to create a spa experience tailored just for you.
In-Line Sanitation system features a mineral cartridge that treats water for up to four months and a sanitizer cartridge that gradually disperses bromine or SmartChlor over four to six weeks. This system keeps your water consistently clean and healthy with minimal maintenance.
With its advanced 9-stage water-management system, Marquis ConstantClean+ keeps your spa water sparkling clean and fresh through high-flow filtration, ozone purification, and in-line sanitation—minimizing maintenance and maximizing peace of mind.
The Marquis Whitewater‑4 jet features a striking red nozzle and delivers up to 100 gallons per minute (379 LPM) of high‑flow water in the footwell, creating an intense leg and foot massage that feels like a “thunderous volcano” of hydrotherapy.
Starlight LED lighting in the Vector21 Series creates a soothing, customizable ambiance, enhancing your spa experience with vibrant colors and dynamic effects.
The Marquis SmartClean software seamlessly automates your spa’s water care by scheduling deep‑filtration cycles after every use and twice a day when unused, so you can set it and nearly forget it.
Foam-over plumbing insulation in the Vector21 Series helps maintain water temperature efficiently while protecting pipes, ensuring optimal performance and energy savings.
The two pop up back-lit fountains softly illuminate the spa’s perimeter, creating a serene and stylish ambiance while highlighting its premium design.
The MicroSilk upgrade infuses the water with billions of ultra‑fine microbubbles that carry up to 70 % more dissolved oxygen than standard tap water, enabling deeper pore‑penetration, enhanced circulation, and improved skin‑cell hydration. It also creates a finer, suspended‑bubble “sauna effect” that helps retain heat, promote toxin release, and support skin‑health benefits such as reduced fine lines and improved collagen production.
The Cosmic Audio system turns your Vector21 hot tub into an immersive sound experience with Bluetooth streaming, FM radio, twin speakers, and a hidden subwoofer. With USB and auxiliary ports plus an RF remote, you can enjoy complete control of your music while relaxing in the spa.
