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

The AR591+ isnt your average enthusiast pressure washer – its 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 its 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 thats 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 arent 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 doesnt 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 washersin 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.
