Welcome to round one in the Wagner FLEXiO 590 vs 890 bout.

So, a manufacturer launches two separate units, and it feels like you need a degree in decorating to identify the difference between them.

At first glance, the only blatantly obvious variation is that the 590 is a handheld unit, and the 890 has a separate standalone turbine — plus a slight difference in cost.

Both HVLP units are designed with DIYers and home improvers in mind. Simplicity is another similar trait when it comes to operating the two devices — and the burdensome task of cleaning has also been streamlined.

But, some determining factors do set these sprayers apart.

In a nutshell, the 590 sits mid-range in the FLEXiO series. It’s a unit that can handle a diverse range of home improvement projects — from medium size to the finishing touches.

The FLEXiO 890 is one model up from the 590 — its capability matches like for like tasks, but provides higher rates of coverage and a fatigue-busting design.

Take a ringside seat and join me to find out if there is a clear champion — and why.

Wall painting with HVLP Spray gun

Included Nozzles

The split gun technology in the FLEXiO 590 is like having two guns for the price of one. Firstly — the iSpray nozzle. It copes with all your heavier mediums and larger jobs — without the need to thin your chosen paint. This makes for a more efficient machine — allowing you to crack on with the task at hand. Secondly — the Detail Finish nozzle. This is ideal for when you need to add finishing touches or complete more intricate work — helping you accomplish those smaller jobs, such as door frames. Both nozzles are painless to change over, due to the Lock-N-Go technology — a simple twist on the front end, and you’re done. This uncomplicated design also allows for easier cleaning. And, the unit can also be adjusted to either spray horizontally and vertically — making it extremely versatile for different projects.

X-Boost Technology

When it comes to having complete control and achieving the finish you were intending, the X-Boost technology comes into play. The X-Boost turbine drives an operating pressure of three PSI, allowing a spray rate of up to 8 gallons per hour — which (as Wagner says) equates to painting a wall 10 times faster than going old-school with a brush. However, with the FLEXiO 590 being a handheld design, the turbine is integrated into the sprayer body. This does make the actual unit weight in your hand heavier than the FLEXiO 890. The X-Boost technology continues in the form of a power dial — enabling you to control the air pressure generated by the turbine. With nine settings, it allows you to tailor the spray gun to different coatings — from thinner stains through to thicker latex — so you accomplish optimal results for your project. To achieve better control and your desired finish with less overspray, simply turn the power down for less viscous paints and crank the power up for denser materials.


Putting away at the end of the day is a convenient affair — the FLEXiO 590 has it’s very own toughened storage case. Not only does this protect it from dust and detritus gathering, but also knocks and bumps when transporting the unit.

Paint Cup

Each nozzle is accompanied by its own paint cup, and both paint cups are a different size. The iSpray nozzle has a capacity of 1.5-quart (1419 ml), which is adequate to cover the size of a small shed in one go. The Detail nozzle has a smaller 0.63-quart (600 ml) container. This is ideal for completing more complex tasks — it makes the entire unit more compact, ideal for accessing tight spaces.

Who Should Use the Wagner FLEXiO 590?

Capable of completing a range of projects on the strength of the Detail and iSpray nozzles. This is an excellent sprayer for DIYers with a desire to cover midsize and small surfaces — from garden decking to cabinet doors. However, when loaded with paint, plus the weight of the unit, some may find the 590 on the heavy side for larger, lengthy tasks.

Pros of the FLEXiO 590

  • Spray rate of 8 gallons per hour.
  • Suited for small and midsize projects.
  • Copes with stains through to latex — without thinning.
  • Durable storage case.
  • Includes two nozzles — for detail work and larger surfaces.

Cons of the FLEXiO 590

  • May prove too heavy for longer duration tasks.
  • Is being replaced by the FLEXiO 3000.

Included Nozzles

Just the same as the FLEXiO 590, the 890 also includes two separate nozzles — the Detail Finish and the iSpray. Consequently, it’s also ideal for a multitude of jobs and uses — with stains, sealers, lacquers, oil-based primers, and latex — without thinning. The settings may also be adjusted to provide horizontal, vertical as well as wide and narrow patterns.

X-Boost Technology

The power dial and turbine are once again connected by X-Boost technology. Although, in this unit, the turbine is a separate entity. Integrated into the storage housing, the turbine is based on the ground. As the bulk of the weight is on the floor, the business end of the machine has an overall lighter feel. This reduces the chance of tired hands and arms. However, you can still achieve sufficient reach with this sprayer, thanks to the 11.5-foot air hose, which connects the X-Boost base and spray gun. This turbine also offers a bit more bang for its buck. It yields an operating flow rate of 8.4 gallons per hour — meaning that you can complete projects somewhat faster than with the FLEXiO 590. The power dial takes a minimalistic approach, with no series of numbers displayed (unlike some of the other models in the FLEXiO range). To adjust the power level, turn the dial to the thinnest part of the marking — and you guessed it, as you turn the dial to where the marking widens, the power goes up.


This is where the difference clearly becomes apparent between the Wagner FLEXiO 890 vs 590. As I mentioned earlier in this review, the turbine is housed separately in a floor-standing box, which cleverly doubles as a storage case. It’s large enough to fit all the components of the 890 in one convenient place — protecting from the elements and preserving your machine.

Paint Cup

Once again, the FLEXiO 890 also includes two cups — owing to the split gun feature. A smaller 0.63-quart (600 ml) container with the Detail nozzle and 1.5-quart (1419 ml) to partner the iSpray. Between the two, you can handle large and small projects without the need to refill the cup too often. The cups are also opaque, allowing you to keep track of exactly how much paint you have remaining.

Who Should Use the Wagner FLEXiO 890?

As we’ve established, the FLEXiO 890 is a next level sprayer when compared to the 590. If you’re content with the 590 but want a slightly faster spray, the 890 is a great choice. Because of the separate turbine lightening the load, the 890 is also a fantastic option if you’re in your golden years — or intend to take on time-heavy tasks where fatigue could rear its head.

Pros of the FLEXiO 890

  • Delivers 8.4 gallons per hour.
  • Separate spray gun from the turbine.
  • Horizontal and vertical spray patterns.
  • 11.5-foot hose.
  • Includes two paint cups.
  • Sprays unthinned coatings from stains through to latex.

Cons of the FLEXiO 890

  • Louder than some other sprayers.
  • Being replaced by the FLEXiO 5000.
  • Many similar features when compared to the lower cost of the FLEXiO 590.

With so many shared features — number of nozzles, job size, and medium usage — a clear knockout blow hasn’t materialized. So, the FLEXiO 590 and the FLEXiO 890 need to go to the cards.

In my estimation, the 890 sneaks in front to claim the win.

The separate turbine combined with the 11.5-foot hose makes spraying sizable projects less tiresome in the arm department. Furthermore, the enhanced delivery rate of 8.4 gallons is ideal if you’re seeking rapid coverage.

However, the 590 isn’t inadequate by any stretch of the imagination and could appeal to DIYers with occasional use in mind. It still takes care of a wide range of mediums without thinning and delivers different spray patterns over intricate and vaster projects — on account of the split gun technology.
