CLEARRAY® Plus 4-stage filtration

CLEARRAY® utilizes the same UV-C technology that beverage manufacturers, municipal waste water plants, hospitals and other health care environments use without producing or adding gas, chemicals, or other by-products to the water as a result. Learn More. And, a 4-stage water filtration system keeps water clean and free of debris quickly using four stages: ProClear™ Filter, ProCatch™ Filter Bag, surface skimmer and a pleated filter.


Jacuzzi® Brand PowerPro® Jets deliver a high volume, low pressure hydromassage through Aqualibrium™: the perfect mix of air and water. As the first company to pioneer jetted water technology, only Jacuzzi® can deliver a massage experience that a legacy that spans nearly 60 years can bring.


PowerPro® FX Jets (19)

Jacuzzi Hot Tubs introduced these jets, with their unique directional rifling action that creates a spiral stream of air and water – perfect for stimulating small muscle groups. Fully adjustable for high or low pressure, exclusive PowerPro FX Jets have a rejuvenating effect and can help overworked, overstressed muscles and joints.


PowerPro® FX Large Rotational Jets (3)

Patent-pending jets that deliver intense hydrotherapy without moving parts, the jets are the larger, more powerful version of the original Jacuzzi FX jets. Their distinct spiral action produces a surging stream of air and water that provides a vigorous massage to larger muscles in the back and shoulder areas.


PowerPro® FX Small Jets (8)

Based in the FX technology, the FX Small Jets are perfect for a focused massage on key pressure point areas, such as your feet. The jets are adjustable, making it easy for a spot-on foot massage.


PowerPro® FX Large Jets (2)

The PowerPro® FX Large Jets focuses on the middle of the back relieving tension and muscle strain, typically caused by poor posture. The FX Large Jet gives a spiral action massage to the back promoting better circulation.


PowerPro® FX Rotational Jets (4)

Using the same FX technology, the PowerPro® FX Rotational Jet focuses on smaller muscle groups with a kneading effect to stimulate surrounding tissue.


PowerPro® MX Jets (3)

This is the original Jacuzzi jet, perfected. Virtually every jet manufactured today is based on this unique and innovative design. Jacuzzi’s PowerPro® MX Jets deliver the maximum volume of water per minute – more than any other jets available today. The big, bold massage action of the MX Jet feels comforting as it works deeply to soothe tired and sore muscles.

Rated 4 out of 5 by from Great but Hot tubs are great but why no wi- fi connectivity to control tub pumps or temperature. Also no WAY this thing costs 15-16 bucks a month to run. Installed in July and my first electric bill DOUBLED!!! Plan on 70-80 bucks a month to run and good luck in the dead of winter- oh yeah - I have the foil insulation package installed too

Rated 4 out of 5 by from great hot tub! unfortunately mine leaked in some great hot tub, but unfortunately mine leaked in some hidden internal spot. i really appreciate the fact that you immediately honored the warranty and replaced the tub. in fact you even went beyond the requirements of the warranty and paid for shipping and installation.

Rated 1 out of 5 by from Leaking We bought our first tub about 5 weeks ago. One week after delivery, the waterfall and manifold were leaking. It sat unusable for 3 weeks until another one came. Luckily the store we bought it from, understood our feelings about wanting a new one and even sent an electrician to do the wiring during the exchange. We thought we were crazy, when after one day....it was leaking!!! This time, inside the cabinet! We regret ever buying a jacuzzi product, in fact we will probably be returning this one too!

Rated 5 out of 5 by from Our daily sweet moment! August 26th I start our new Jacuzzi j-345 and since then we're in it almost every day, what a wonderful pleasure!!!

Rated 4 out of 5 by from Seems to work Great! Have been enjoying the spa now for about a month. Works well, different seats give a completely different sensation. Had one of the nozzle cover come off, and the pillows seem to come off too easily, but that could be because it was a demo at the fair. Will have to notify the dealer to see how well they take care of it.

Rated 5 out of 5 by from my english is not so good but my hot tub is perfec .8 hours of cleaning keep de water very clear and neet
Date published: 2015-08-27
Rated 2 out of 5 by from Poorly designed control system New j435 hot tub. The filtration system does not run unless the heater is heating. In hot weather, the filtration rarely runs even though filtration is set to 24 hour mode. The filtration controls need to run separately from the heat controls. A second problem is that the corner pillows will not stay in their brackets. Annoying, for sure.
