Annovi Reverberi AR591+ | "Pro-Grade" Enthusiast AR Pressure Washer

The AR591+ isn’t your average enthusiast pressure washer - it’s a custom-tuned, quality built unit with pro-level features, serious performance, and durability. Unheard of at this price point... 

Our custom tuned, Annovi Reverberi 591+ is truly an exceptional pressure washer, and its surprised us in every way. Its “supposed” to be an enthusiast-level unit, but it’s packed with pro-level features, that rival even some of the professional pressure washers that are priced well over $1,000. 

Lets start with the heart of the unit, and that’s the brass pump - and yes, this is a genuine brass pump head, with 3-axial pistons and a wobble plate drive. Why is this a big deal? Well, pressure washers around this price point are plagued with aluminium pumps. Although these pumps are lightweight, they are much less durable & resistant - and are prone to cracks, leaks & seizing. Brass pumps on the other hand are the complete opposite, and have a far better heat tolerance, preventing warping & cracking. Aluminium pumps are really “throwaway units”, they aren’t worth fixing if they break, meaning they are, in a way, setup for failure. Brass pumps on the other hand are made to last, and can be serviced or re-built - replacing any seals, pistons, valves, whatever. They are built with long term durability in mind, and they deliver a much better performance when compared to the aluminium pumps.

But it doesn’t just stop there, not only does the AR591+ feature a premium, professional grade brass pump - its also equipped with high quality stainless steel pistons. Those comparable units that feature aluminium pumps are notorious for utilising aluminium pistons, or an even cheaper mixed metal composites. These pistons are moving back and forth thousands of times per minute. Making sure your machine is equipped with proper stainless steel pistons means they will be much more resistant to warping, corrosion and degradation - even under high PSI compared to any aluminium/coated/composite pistons (which are even found in many units more expensive than the AR591+). 

Now, putting this all to the test is the output of the AR591. This is where we get to see the real performance of the unit, and where this machine really separates itself. While most pressure washers in this range inflate their numbers at higher power outputs, the AR591 delivers a tested 8.2L/min of water flow (Max 9L/min) and 1200 PSI (Max 1950 PSI) at the nozzle using a standard 10 amp plug - which is exactly what you want for detailing specific applications. Higher water flow means faster, more effective rinsing and thicker, more consistent foam when using a foam cannon.

The reason we have an AR591+ version (which can’t be found anywhere else in the world), is that we have been working with the Annovi Reverberi engineering team in Italy for the past 8-10 months (most of 2024 & early 2025). Specifically working on optimising this machine for the detailing market. We have fine tuned the working pressure and maxed out the water flow to give us a unit that is tailored for the detailing market & prioritise the metrics that mean the most for detailing.

Combine this with the brushless induction motor and a True Total Stop System (TSS) and you’ve easily got one of the highest spec’d, pro-level “enthusiast” units on the market. But what makes true TSS so important? Most machines in this range have a basic motor cut-off - the pump stops when the trigger is released, but the pressure stays loaded in the system. That means heat builds, seals wear faster, and your machine strains even while it’s “off.” True TSS, like what’s in the AR591+, completely unloads pressure inside the pump. This extends the lifespan of seals and pistons, reduces energy draw, and prevents the annoying kick or pressure surge when you re-engage the trigger. It’s a premium feature that’s almost unheard of at this price point - and it’s one of the clearest signs (if you weren’t already convinced…) that you’re dealing with a professional grade pressure washer that is built to last.

Packed with all these premium features, the AR591+ brings it all together in a compact, all-in-one system - complete with an integrated trolley, hose reel, inspectable inlet filter, pressure gauge, adjustable pressure, and more. It’s built to be portable, practical, and ready to use straight out of the box. But if you are looking to push performance even further, and upgrade your wash, we offer a AR591+ Essentials Kit upgrading your gun, lances, nozzles & more, customising your pressure washer exactly how you like it. 

Top this all off with our exclusive, Waxit Enthusiast+ AR Warranty which features a 3-year manufacturer warranty (protecting against any defects in material & workmanship), along with our unique 1-year Waxit accessory warranty to give you complete peace of mind & confidence with our AR591+. 

Overall, the Annovi Reverberi 591+ isn’t just a great value pressure washer - it’s truly in a class of it’s own. With a genuine brass pump, quality stainless steel pistons, impressive 8.2L/min of tested real water flow & a long list of premium features throughout - this unit punches so far above it’s weight it’s hard to believe it still falls in the “enthusiast” category & is available at this price point. It’s built like a professional grade machine, pumps out incredible performance & with an upgrade kit available to further improve & customize this incredible unit you can see why we're excited to bring you a pro-grade pressure washer without the pro-grade price!

If you are sick of warranty claims, cheap aluminium pumps & just looking for a pressure washer that's going to offer incredible performance without breaking the bank - the AR591+ is almost impossible to look past.
