Annovi Reverberi AR591+ Pressure Washer | Essentials Upgrade Kit

The AR591+ Essentials Kit combines serious performance with upgraded ergonomics, giving you pro-level control and durability in one complete kit.

The AR591+ isnt your average pressure washer – its a custom-tuned, quality-built unit with pro-level features, serious performance, and durability thats unheard of at this price point, and our Essentials Upgrade Kit only pushes this even further.

Our custom-tuned Annovi Reverberi 591+ has surprised us in every way. Its supposed to be an enthusiast unit, but its packed with pro-level features that rival even some professional pressure washers.

Lets start with the heart of the machine – the brass pump. Yes, this is a genuine brass pump head with 3-axial pistons and a wobble plate drive. Why is this such a big deal? Because most pressure washers at this price point are plagued with aluminium pumps – lighter, sure, but much less durable. Theyre prone to cracks, leaks, seizing, and heat damage. Brass pumps are the complete opposite: stronger, serviceable, rebuildable, and designed to last long-term.

And it doesnt stop there. The AR591+ also features high-quality stainless steel pistons, whereas many comparable units settle for aluminium pistons or mixed-metal composites – even on more expensive machines. These pistons move back and forth thousands of times per minute, so having stainless steel means better resistance to warping, corrosion, and degradation, even under high PSI.

Now, putting this to the test – this is where the AR591+ really separates itself. While most machines in this range inflate their specs, the AR591+ delivers a tested 8.2 L/min of water flow at a working pressure of 1200 PSI, using a standard 10 amp plug. Thats exactly what you want for detailing – higher water flow means faster rinsing and thicker, more consistent foam. Pair this with one of our foam cannons for unbeatable performance.

The Essentials Kit transforms the AR591+ – delivering a serious upgrade in ergonomics, durability, and efficiency. It replaces the standard long gun and fittings with a compact MTM SG35 short gun featuring a built-in swivel to eliminate hose tangling, a ventilated insulated lance for improved comfort and heat resistance, and a full set of Tecomec Ceramic 1/4″ QC Nozzle Set. These enhancements dont just make the machine easier to handle – they offer a more refined, durable, and professional-grade setup, allowing faste
