Ar Annovi Reverberi AR630-HOT Pressure Washer

This little guy can reach temperatures of 180°F which will be enough to deep clean grease, grime, and other dirt.
It has a maximum PSI of 1900. So it’s actually one of the only options on our list that is more suited to home use than commercial. However, you can definitely still take it to work and see remarkable results.
Keep In Mind
What We Like
Serious Safety Features
Safety comes first with this pressure washer. The trigger gun helps you determine when it’s definitely switched off, giving you peace of mind. You can also lock the trigger to avoid accidental sprays.
Lastly, it automatically shuts down when it detects an electrical ground failure.

Choose your own PSI with the adjustable pressure gauge. This is ideal since different surfaces require a different PSI. For instance, you may want a different PSI when washing a bike versus a driveway.
Mesh Water Filter
This comes with a mesh-designed water filter, making the device easy to clean. Overall, this extends the pump’s life so you can get years out of the product.
Suitable for Home and Professional Use
I mentioned earlier that hot water pressure washers are more suitable for commercial use rather than home use. But with a maximum PSI of 1900 and a 2.1 GPM, this is an excellent choice for home and professional use.
What We Don't Like
Not on Wheels
One of the most significant drawbacks of this appliance is that it’s not on wheels. This makes it very difficult to maneuver and takes some of the practicality away from this option.
No Attachments Included
Due to the adjustable pressure gauge, this doesn’t come with nozzles or the option to attach any nozzles. If you’re used to this, this machine may require a bit of a learning curve. A few customers were put off by this.
You Need To Preheat Water
Make sure you have a hot water source before buying this. The machine itself will not heat the water for you. Instead, you must connect it to a hot water source like a tap to utilize hot water.

Clean Various Surfaces
You can use this for a variety of jobs. This includes parking lots, decks, patios, sidewalks, driveways, pool tiles & decks, and much more. It’s best for commercial work due to the high power, but it can still tackle a range of duties.
59 Pounds Lightweight
Compared to some of our other recommendations, which are often up to 600 pounds heavy, this is a lovely little lightweight option. It only weighs 59 pounds due to the plastic frame, so it’s easy to maneuver (though maybe not as durable).
Generous Range of PSI
While this has a maximum PSI of 4000, it has a minimum PSI of 1250, making this a super duper versatile product. You can use it for home use or commercial. The lighter pressure allows you to use this on house siding and cars without causing any damage.

This is on wheels, but there’s more to it than that. It has two 10-inch rubber tires on the rear with two non-marking casters at the front. This lets you easily maneuver it in various directions while protecting your flooring.
What We Don't Like
Plastic Housing
Most of our other recommendations have a sturdy steel frame that is durable and rust-resistant. However, this plastic one is slightly cheaper, less durable, and more subject to damage.

What We Don't Like
1500 PSI
The PSI is quite low for a commercial, gas-powered pressure washer. At 1500, this matches the average electric pressure washers used for the house. We don’t recommend it for home use since the manufacturer hasn’t specified that. However, it may not be strong enough for some commercial tasks.

Is a Hot Water Pressure Washer Worth It?
What are the main benefits of choosing a hot water pressure washer, especially one that also works with cold water?
- Deeper cleaning: Hot water can more easily blast away dirt and keep it away. It’s quicker at cleaning surfaces than cold water is.
- Good match for detergent: Hot water works better with pressure washer detergent, particularly on greasy build-up. This makes it great for cleaning driveways and garage floors.
- Easier to clean: Hot water takes the elbow grease out of many jobs, making it much easier to blast away dirt.
How To Choose the Best Hot Water Pressure Washer
Before we get into the nitty-gritty details you should consider when buying a hot water pressure washer, please note that these are designed for commercial use.
These appliances are expensive, super high power, and very hot — so they’re not ideal for pressure washing around the house. Plus, your home driveway, garage floor, and other surfaces probably don’t need scalding hot water. Normal pressure washers will work just fine.
These pressure washers are mostly aimed at people getting paid to pressure wash. A hot water pressure washer will get you through jobs quicker. Just know you’ll need health and safety training for using one.
Cost
Firstly, it is essential to carefully consider the cost before deciding. These power tools are not cheap. However they come in various prices, but we’re talking in the thousands.
Portability
Consider how easy it is to maneuver. Is it on wheels? Easy to push around? How heavy is it?
We’ll let you know all the details of each pressure washer that aids its portability.
Type
You’ll find both gas and electric hot water pressure washers. Electric ones are more eco-friendly and don’t require the use of gasoline. But gas pressure washers are more powerful, so if you need a high PSI, you may want to consider a gas pressure washer.
Heating System
Consider how the power tool heats up the water. This is usually either done via a burner or a heating coil.
A burner supplies heat and is very common in gas pressure washers. It can raise temperatures of the incoming water bringing it up to 250°F. Some can even provide steam cleaning.
Heating coils work a bit differently. They are made of pipes or tubing and are visible on your appliance. These work to heat your water up, too, but they may not always have the same power as burners.
Can You Use Cold Water in a Hot Water Pressure Washer?
Many hot water pressures allow you to use both cold and hot water. Some have a dial that lets you control the temperature. If that sounds like something you’d like, definitely look for one with this feature.
Water Pressure
Check the PSI of the appliance. This measures the amount of pressure per square inch. The higher this number, the more powerful the pressure washer is. My recommendations range from 1,500 to 4,000.
Also, consider GPM — gallons per minute. The higher this is, the more water can go through the machine at a time. This gives you more force when cleaning. My recommendations range between two and 21 PSI.
Some may advertise their pressure on cleaning power — CP. This is achieved by multiplying the PSI with the GPM.
If a machine has 4000 PSI and four GPM, then the CP is 16,000.
Safety
Because these are powerful machines, choosing one with some helpful safety features is a good idea. This could include a shut-off switch on the trigger gun, a safety valve for using low pressure, a safety lock to prevent accidental uses and much more.
Extra Features
What extra features does the pressure washer come with? These could be wands, spray guns, hoses, nozzles, and other attachments. These features could help you have more control over your pressure washer.
Tips for Maintaining Your Hot Water Pressure Washer
You’re about to spend a lot of money on a hot water pressure washer, so taking care of it is important. Here are our top maintenance tips:
- Turn the machine off when not in use: Don’t leave your pressure washer turned on for more than three minutes when you’re not spraying it. This can damage the pump, and you may require a replacement. Always turn off the machine if you are going to step away from it.
- Check pump and oil: Always check the pump and engine oil levels before each use.
- Drain moisture: Drain moisture from the heating coil regularly. There should be a drain valve on the boiler. Leave it open for a while, at least once a week, to remove any moisture residue.
- Switch off the heater when finished: Always remember to turn off the heater before you stop spraying water. This ensures that only cool water flows out at the end. It also protects the metal part of your sprayer wand and allows the heating coils inside the cool down before you store the pressure washer.
- Storage tips: If you plan to store your pressure washer away for a couple of weeks or longer, drain the water and chemical systems. Fill the machine with anti-freeze. Next time you go to use it, it will be in mint condition.
- Check the air filter: Once a month, check the air filter to make sure it isn’t clogged with dust or dirt. You will likely need to replace the filter every six months.
- Change engine oil regularly: Change the engine oil every 100 hours of work or every three months. Only use oil that the manufacturer recommends.
- Change pump oil regularly: Change the pump oil when you get the machine and replace the pump oil every 250 hours of work or every three months.
- Change burner fuel filter regularly: Replace the burner fuel filter every three to six months.
- Deal with condensation: If you find condensation or water in the fuel tank, drain the tank and leave it open for a little while.
Bonus Tip
FAQs
How Does a Hot Water Pressure Washer Work?
A hot water pressure washer works by heating the water to a high temperature and blasting it out using extreme pressure. The heated water gives the pressure washer increased cleaning power.
Do Hot Water Pressure Washers Heat the Water?
Hot water pressure washers do heat the water. They contain a small boiler that warms the water before it blasts out through the nozzle.
Can You Run Hot Tap Water Through a Regular Pressure Washer?
Running hot tap water through a regular pressure washer could damage the pump and inner casing. This could lead to leaks and, ultimately, pressure washer failure.
Which Is Better: An Electric or Gas Pressure Washer?
Deciding which is better between an electric and gas pressure washer comes down to several factors. Electric pressure washers are cheaper, easier to use and maintain, and lighter, whereas gas models are more powerful but cost more and require higher maintenance.
What Temperature Should the Water in the Pressure Washer Be?
The water temperature in a pressure washer should be 140 degrees Fahrenheit. However, some hot water pressure washers offer a steam option, which heats the water to 280 degrees Fahrenheit.
Fire the Hot Shot
With these hot water pressure washers, you can fire hot shots — literally. Remember, hot water pressure washers do a better job than cold water at busting out grease, grime, and all kinds of other dirt.
Always consider the type of pressure washer, the PSI and GPM, the portability and the heating system. Never miss a detail before you buy, and you will end up with one that brings no surprises (other than how awesome it is).
My roundup of the seven best on the market will surely match you with one that will serve you and your projects for a long time.
