How we picked the Best Simpson Pressure Washers
It might be challenging to select from the several gas and electric Simpson pressure washers available today. Based on the various sorts of tasks needed around the house, we examined and ranked some of the finest solutions.
We selected gas-powered heavy and medium-duty versions with greater combined psi and GPM capacities. For light-to medium-duty cleaning activities where more potent gas machines risk damaging delicate surfaces, electric pressure washers thrive. A cost-effective, lightweight, small-footprint electric variant appropriate for storage areas and modest jobs was also offered. These models illustrate each category’s usefulness and worth.
What are the things to consider when choosing the best Simpson pressure washer?
It’s useful to have a way to focus the search when there are several models to pick from. When buying, the major features of pressure washers listed below might be useful.
Gas vs. Electric
Compared to electric pressure washers, gas pressure washers provide more water pressure at a higher flow rate. Gas pressure washers are ideal for bigger, messier chores like washing fences, driveways, and house siding because of the fact that they don’t need to be connected to a power line.
At around half the gas flow rate, electric pressure washers usually provide somewhat less water pressure. Compared to their gas-powered predecessors, they are often more compact, lighter, quieter, and simpler to store. For cleaning common home items like vehicles, lawn mowers, patio furniture, driveways, or patios, electric pressure washers are a wonderful option.
Targeted Purpose
Think about the Simpson pressure washers intended application before purchasing. Use the psi rating as a tool for evaluating a model’s capability to carry out the required duties.
It is reasonable to use a more powerful Simpson pressure washer for a simpler job, but caution must be exercised to protect the material’s finish and surface. The most suitable pressure washer psi rating for each of the common household cleaning tasks includes:
- Cars, bikes, and grills: up to 1,500 psi
- Decks and fences: 2,500 psi
- House siding and driveway pavement: 3,000 psi
- Industrial cleaning and paint stripping: 4,000 psi
Flow Rate and PSI
The flow rate and water pressure of a simpson pressure washer are used to determine how effective it is in cleaning.
Flow Rate: The volume of water that flows through the machine at any particular moment is known as the flow rate and is measured in gallons per minute (GPM). A pressure washer’s power may be determined by looking at its GPM rating. Soil is removed from a surface twice as quickly when the flow is increased from 1.0 to 2.0 GPM.
Water pressure: it is the force of the water stream the washer produces, is expressed in pounds per square inch (psi). The PSI rating of a pressure washer reflects its capacity to remove debris that has become attached to a surface. The distance the operator can hold the spray tip from a surface increases as the water pressure is increased from 2,000 to 3,000 psi.
Spray Wand
Spray wands for Simpson pressure washers are not all the same. Typically, the trigger is either moulded or lever-style, and the spray gun’s body is made of plastic. The connections between the spray gun and pressure hose and between the spray gun and the wand can also be made of heavy-duty metal quick connectors or light-duty plastic parts.
Plastic parts found in light-duty electric washers would not withstand the high pressure generated by heavy-duty machines. Entry-level devices frequently come with a plastic wand and an adjustable plastic spray tip. Premium pressure washers have spray wands made of stainless steel with brass fast connections for changing the spray tip.
Portability
There are several varieties of portable simpson pressure washers. The washer’s overall size and weight, frame design, handle arrangement, and wheel type and size are important characteristics to look for. The smallest, lightest models resemble a large lunchbox or a small cooler in size. Since they are lightweight, small, and without wheels, they are simple to pick up and store.
The majority of Simpson pressure washers feature a frame similar to a hand truck or wheelbarrow. Although a vertical hand-truck layout removes the majority of the user’s weight, it can be a little top-heavy. Although the wheelbarrow configuration can be quite stable because of its low centre of gravity, it also places greater weight on the person being transported.
Wheel size & type
The unit’s movement on varied surfaces is influenced by the wheel type and size. On firm, flat surfaces, rotating wheels make it simple to move in any direction. Large wheels with a diameter of 8 inches or more run smoothly across uneven ground. For navigating grassy, muddy, and other natural conditions, pneumatic tyres perform well. Moving a big, heavy model is made simpler and safer with a suitable handle height.
Accessories
Accessories have an impact on the washer’s cleaning performance and ease in addition to the main unit, pressure hose, and spray wand. Changeable spray tips vary the spray pattern from a powerful narrow jet to a dispersed broad fan to accomplish different jobs. Cleaning with a turbo nozzle is up to 50% quicker than using a standard spray tip since it produces a narrow rotating stream.
Cleansers are applied to surfaces using foam cannons and foam cannon soap tips so that they stick to the surface , soak in and remove debris. Surface cleaners, power brushes, a chemical nozzle kit, and more are just a few of the additional Simpson pressure washer accessories that are available for separate purchase.
