Renting or Buying Pressure Washer

One problem that almost all of us have despite what kind of environment we are currently living in has to be cleaning. As humans prefer to live in a clean and comfortable place, you will need to deal with lots of cleaning processes from taking a shower, doing laundry, till removing those grimes and dirt on your house’s deck or walkaway. It sounds tiring but needs to be done and for those who want to be convenient, especially when dealing with lots of surface, a pressure washer will be an amazing investment.

Not only buying them yourselves, many of us can rent one as well depending on how often and how much we spend for cleaning. Of course the more often we do it the better it is to have the tool in the house but, consider the price or rent fee first before deciding. For those who will be using the washer about three times a year will probably better to have their own washer as single day rent can cost from $40 to $100 in which many electric washers are as affordable from $100 to $200.

Pressure Washer Types

Talking about the type of pressure washers, there are two types we can choose depending on what you want or need from the unit; electric pressure washer and gas pressure washer. The reason why gas pressure washers are more expensive than the other type is because this one has better advantages over the electric type. First is from the power rating since electric models have an upper limit of about 2000 PSI due to the low capability of 15-amp electric motors which commonly range from 1500 to 1800 PSI.

On the other hand, gas pressure washers can easily go over this number or at least 2000 PSI to 2500 PSI even those on the entry level and the higher-end units can deliver 4000 PSI or higher especially the commercial grade that can deliver a massive 7000 PSI usually used by professionals. The second is water flow rating and here gas pressure washers also have the upper hand. In general an electric power washer gives about 1.4 to 1.5 GPM in which you can find the gas type above the rating easily.

Another consideration is probably the components or engines that are often more durable and reliable in a gas pressure washer as the unit can deliver higher power. However, while most electric pressure washers are made from plastic, quality is subjective to the manufacturer and how they decide to build their products.

About Sun Joe SPX300 and SPX3500

Just like everything else, it is best to buy something based on what you need since not all of us will have the same preference or opinion on what works best in their application. If you are here then it means having a pressure washer at home will be much more convenient and cost efficient for the prolonged time but for a regular homeowner who is doing routine cleaning and does not plan to reach for a heavy-duty washer, the electric type will be the most affordable option.

Many $100-$200 pressure washers are already amazing for this type of application and one brand you may want to consider is Sun Joe. We are sure most people are familiar already with this popular brand because many are loving their performance especially for light to medium and in customer level products. They do carry various models to consider based on what you need and want from the washers yet the price point is so attractive to let people have reliable tools without spending too much.

Two powerful but affordable models from this company are Sun Joe SPX300 and SPX3500 which are very close to each other in terms of capabilities and price point. As the name suggests, they are direct brothers and chances are you can find the same capabilities or features from both washers but, being a higher model makes the latter also carry some advantages over the little sibling. What we love from these washers is how good they are to deal with dirt and leaf stain or mildew.

They are very reliable and in fact you can transform a dirty and seemingly abandoned patio or deck due to the lack of previous maintenance clean and looks fairly new in minutes depending on how large the area and how severe the buildup is. However, we don’t think Sun Joe SPX300 and SPX3500 are for serious usage and nowhere near enough if you want those same results and efficacy like what experienced contractors have since none of them are powerful enough for pavement or those dealing with lots of moss.

Sun Joe SPX300 and SPX3500 Design

These washers are looking almost like any washers you can find out there and side by side are very much similar to each other but, we can also distinguish them easily based on the design alone especially with the SPX3500 has this dominant black face plate compared to the little brother which is prominently green. They have a high handle clearance and a pair of huge wheels which is very convenient when you try transporting the unit as they are 31 and 46 pounds respectively.

As you can see, these washers are mainly build from plastic material and while some may worried about how long they can last being used often, we do think Sun Joe SPX300 and SPX3500 are very well made and the plastic doesn’t feel flimsy or cheap as well, in fact they are thick and sturdy. What you may want to note is that they will come in parts so there will be some assembly process needed to put all of them together.

Sun Joe SPX300 and SPX3500 Pressure and Water Volume

When shopping for a pressure washer, of course we want to know how powerful it is and the first thing you may want to know is how useful Sun Joe SPX300 and SPX3500 are. The prominent difference between both of them is on the water weight or pressure itself because respectively they are able to deliver up to 2030 and 2300 PSI. These electric washers are not very powerful when compared to professional models but performance wise you can clean various surfaces like patio or washing car with them.

We do think they are very similar and while there is difference in the water pressure, the difference doesn’t make much of a result gap; probably because their motors are also almost identical at 1800 and 2000 watts respectively. To aid different cleaning needs, you can use these washers with 5 quick connect nozzles. What’s surprising is that the SPX3000 actually has a higher water volume at 1.76 gallons per minute compared to 1.48 GPM which may affect the cleansing performance as well.

Sun Joe SPX300 and SPX3500 Performance 

When it comes to how good Sun Joe SPX300 and SPX3500 in real-life performance, you can clean almost anything with them but still, we do think they are more ideal for light to medium usage for example routine maintenance in which they are best at. For restoring old houses with poor maintenance and very thick buildup especially moss, you will probably need to put more effort to get the best result from both washers yet the slightly higher pressure in SPX3500 seems to aid the cleansing a bit faster.

The additional 5 different nozzles to use including for soap is great to make sure you can match the mode with the kind of application we are currently dealing with but, pay attention to what type of soap being used. Sun Joe has their own soap for cleansing and make sure to use a light or liquid soap with very low viscosity since thicker soap will be very difficult to use with the black soap nozzle.

Sun Joe SPX300 and SPX3500 Feature

The last thing we want to mention is their features and this is specifically on the soap tank available on both models. If you look closely there are two soap bottles placed at the top front of the SPX300 washer and this model can use both soaps at the same time or only one adjusted through the dial. On SPX3500, this soap bottle is put at the back of the unit and there is only one tank to contain the liquid with the adjustment knob on front to dial how much liquid is used.

Sun Joe SPX3000 vs SPX3500

You can pick any of them as they are equally reliable but Sun Joe SPX3000 and SPX3500 are different. The SPX3500 has brushless motor which is not only meant to last longer but also effective and efficient especially when combined with the lower GPM to save water. This model is also slightly stronger in pressure and runs quieter but only has one soap bottle instead of two that can be combined in SPX3000.

There is no bad option between the two as they are very reliable but if you are willing to spend a little more, we highly recommend SPX3500 as it may last longer and be more efficient in water consumption without reducing its performance.
