Why Choose Our Pressure Washers for Trade and DIY Cleaning Tasks
Our customers trust us for reliable machines, fast delivery and expert advice. All pressure washers are backed by our UK-based support, and our product pages clearly indicate if a unit is more suited to trade use or home cleaning.
Pressure Washer vs Power Washer: Understanding Flow Rate, Pressure and Cleaning Power
People often mix up pressure washers with power washers. While they share a similar purpose—removing dirt and grime—there are some key differences. A power washer often heats the water, whereas most pressure washers rely on max pressure and flow rate to get the job done. For high pressure cleaning of stubborn dirt or tough surfaces like concrete or industrial floors, a higher flow rate combined with more pressure is essential.
At Promain, we offer both electric motor and petrol power washers, so you can match the power source and pressure setting to your cleaning tasks. Whether you're rinsing off garden tools or cleaning a workshop floor, choosing the right washer is a game changer.
Explore Our Best Pressure Washers for Heavy-Duty High Pressure Cleaning
For commercial and high pressure cleaning, we recommend looking at the Slip Stream Pro series:
Slip Stream Pro 12 with 18" patio cleaner head
-
Slip Stream Pro 20 with 20" surface cleaner
-
Slip Stream Pro 21GT with 24" cleaner and upgraded build quality
These machines are designed for professional-grade pressure washing—delivering high flow rates, durable components, and attachments like dirt blaster lance and turbo nozzle options. Ideal for removing dirt from large surfaces like car parks, stone patios or warehouse floors. They also offer compatibility with foam cannon accessories, making them powerful washers for a wide range of different jobs.
Cordless Pressure Washer and Portable Options for Outdoor Cleaning Tasks
Not all cleaning tasks need industrial strength. For garden paths, vehicles or washing down outdoor spaces like decking or garden furniture, a cordless pressure washer is the more practical choice. These lightweight units are easier to handle and often feature variable nozzle settings for tackling a variety of outdoor cleaning tasks.
Our portable and cordless pressure washer models don’t need a power cord or garden hose connection—some can even draw from a water butt or bucket. They're perfect for lower pressure washers use, and still deliver more pressure than you'd expect from smaller machines. A foam cannon or wash brush can be added to extend cleaning power on more delicate surfaces.
How to Choose the Best Pressure Washer for Cleaning Jobs Around Your Property
Finding the best pressure washer means thinking about how much cleaning power you actually need. For example:
-
Light work like washing garden furniture or spraying off dirt from fences? An electric pressure washer with around 150–200 bar and a decent flow rate should be fine.
-
Heavy-duty tasks like cleaning driveways, walls or prepping for paint? Go for a high pressure washer with 250 bar+ and large hose length for easier reach.
Other things to factor in include hose type, power source (battery, petrol, electric motor), and available accessories like spray lance, extendable lance or patio cleaner attachments. You can also look at detergent tanks, soapy water use, and pressure setting options for working in an inconspicuous area before moving on to hard surfaces.
Why High Pressure Washers Make Outdoor Cleaning Faster and More Effective
A high pressure washer gives you the cleaning power to remove dirt, algae, moss, oil stains and other debris quickly. The right pressure and flow rate can make short work of stubborn grime, where other washers would struggle. If you use too little power or the wrong nozzle, you’ll waste time and water. Machines that support a wide fan spray or turbo nozzle ensure faster results without damaging surfaces.
At Promain, all our units—from budget pressure washer options to our trade Slip Stream range—are selected for their ability to deliver max pressure safely and effectively.

Complete Your Outdoor Cleaning Kit with Painting Accessories and Garden Tools
Pressure washing is often the first step before applying paint, primer or sealants. After using a pressure washer to clean stone patios or render, you can then apply fillers or paint with confidence. This helps coatings last longer, especially on dirty water-prone areas or exposed surfaces.
Our painting accessories include more than just rollers and brushes—you’ll also find everything from wash brush sets to surface prep tools. This way, you’re getting a complete cleaning and painting solution, not just a machine.
Trade-Grade Pressure Washers for Tough Jobs and Larger Outdoor Spaces
Need a powerful washer for industrial jobs? Our Slip Stream Pro 30 with a 36" patio cleaner is built for commercial use, delivering up to 30 litres per minute. It’s designed for extended use on construction sites, warehouses and tough jobs where most pressure washers wouldn’t cope.
These machines also work well with turbo nozzle and dirt blaster lance attachments, helping to cut through layers of grime on concrete, tarmac or heavy-use surfaces.
Compact and Budget Pressure Washer Models for Smaller Outdoor Cleaning Jobs
For everyday cleaning tasks around the home, a budget pressure washer or compact electric unit offers more than enough power. Great for washing down a small patio, cleaning outdoor spaces, or prepping a surface before paint.
Lower pressure washers are lighter, easier to store and come with quick-change nozzles, hose attachments and sometimes built-in detergent tanks. They're a smart choice for homeowners who need reliability without the size and cost of bigger units.
Pressure Washer Maintenance and Safety Tips
To get the most from your pressure washer, regular maintenance is key. That includes checking the hose and power cord, cleaning filters, and inspecting the spray lance for blockages. Always wear safety glasses when operating and test in an inconspicuous area if you’re unsure about surface strength.
Use the correct pressure setting and pair with attachments like a patio cleaner head or variable nozzle for better results. Adding a foam cannon or using soapy water also improves cleaning efficiency on vehicles or painted walls.
Accessories That Boost Cleaning Power for All Pressure Washers
No matter how powerful the base unit is, the right accessories make a big difference. Use a turbo nozzle for stubborn dirt, a patio cleaner for flat surfaces, or a wash brush for garden furniture and cars. Other useful add-ons include:
-
Spray lance extensions
-
Dirt blaster lance
-
Detergent tanks
-
Wide fan attachments
-
Quick-connect hose fittings
At Promain, we stock extras that work with both electric and cordless pressure washer models—helping you finish faster and with less water.
