Bar and PSI matter, but they are only part of the buying decision. Flow rate, lance choice, patio cleaner heads, hoses and bundled accessories can make one pressure washer better value than another for the same household jobs.

Which kärcher pressure washer should you buy?
Choosing between Kärcher models is easiest when you compare the cleaning job, series, pressure, water flow, hose reach and bundled accessories rather than simply picking the biggest number on the box.
Best compact pressure washers for small sheds and garages
Small outdoor storage changes what “best” means. For a compact pressure washer, the right choice is usually the one that fits your shelf, keeps its hose and accessories tidy, and still gives you enough reach for the patio, bins, bikes or car without dragging everything out of the shed.
Bosch vs Kärcher pressure washers: which should you buy?
Choosing between Bosch and Kärcher is less about picking a famous name and more about matching pressure, water flow, power, weight and accessories to the jobs you actually do. Here’s how to compare the listings without being distracted by headline discounts or oversized bundles.
Best pressure washers for bikes and garden furniture
Bikes, benches and outdoor chairs need controlled cleaning rather than maximum force. The right pressure washer should give you gentle spray options, easy handling and useful accessories, without pushing you towards a heavy-duty machine you rarely need.
Pressure washers and power washers can look very similar at first glance, but the right choice depends on what you want to clean. A compact cordless washer for rinsing bikes is a very different buy from a high-pressure petrol model intended for heavier outdoor cleaning.
The key specification is often shown as bar or PSI. Bar is the pressure rating used widely in UK listings, while PSI is more common in some product descriptions. As a rough conversion, 1 bar is about 14.5 PSI. Higher pressure can shift tougher dirt, but it is not automatically better for every surface. Flow rate, nozzle type, hose length and accessories can matter just as much.
When comparing Pressure Washers & Power Washers, use the pressure rating as a starting point, then look at what comes in the box. A patio cleaner, rotary brush, snow foam lance, spray gun or extra hose can change the value of an offer, especially if you would otherwise buy those Pressure Washer Accessories separately.
For light rinsing jobs such as muddy bikes, garden tools, bins and small balconies, you usually do not need the highest pressure rating. A lower-powered or cordless power washer can be convenient if portability matters more than deep cleaning. Models such as the JML Starlyf Pressure Cordless Power Washer and Flymo EasiClean Li Plus sit in this kind of shopping conversation because their appeal is often mobility and quick set-up rather than maximum pressure.
For cars, motorbikes and general outdoor furniture, look for controlled pressure, suitable Nozzles and the option to use detergent or foam if that is part of your routine. A snow foam lance, such as the Draper Pressure Washer Snow Foam Lance for compatible Draper machines, may be more relevant than simply chasing the largest bar figure. Always use a suitable setting and attachment for painted or delicate surfaces.
For patios, paving, brickwork and heavily marked paths, pressure and water flow become more important. A higher bar rating helps, but a Patio Cleaner attachment can make a big difference to coverage and consistency. The Nilfisk Patio Cleaner 128500724 is a good example of why accessory compatibility should be checked alongside the washer itself.
For frequent, larger or more demanding jobs, you may want to compare more powerful electric or petrol pressure washers. The Kärcher HD 9/25 G Classic Professional Petrol Pressure Washer states 250 bar in its product title, putting it in a very different class from compact domestic-style options. That does not mean it is the right choice for every home; it means you should consider storage, fuel type, noise, handling and whether you genuinely need that level of pressure.
Bar and PSI both describe pressure. If a listing gives one but not the other, you can still compare broadly: multiply bar by about 14.5 to estimate PSI, or divide PSI by about 14.5 to estimate bar. A 100 bar washer is roughly 1,450 PSI, while 140 bar is roughly 2,030 PSI.
Be careful with product names. For example, the Einhell TE-HP 140 includes 140 in the model name, but you should still confirm the stated working pressure and maximum pressure in the retailer’s specification. Some brands highlight maximum pressure, while others make working pressure easier to find. Working pressure is often more useful for real-world comparison because it better reflects sustained cleaning performance.
If PSI is not listed, do not assume the model is weaker or stronger. Some UK listings focus on bar, while others prioritise wattage, flow rate or accessory bundles. Compare the full specification rather than one headline number.
Pressure helps loosen dirt; flow rate helps move it away. A pressure washer with a stronger flow rate can rinse a larger area more quickly, while a lower-flow model may feel slower even if the pressure figure looks respectable.
Flow rate is commonly shown in litres per hour. When comparing models, check whether this figure is listed and consider the size of the jobs you actually do. Cleaning a small bike after a ride is not the same as washing a long driveway or several large patio sections.
If two pressure washers have similar bar ratings, the one with the better flow rate, longer hose or more useful lance may be the more practical buy. This is where comparing products and offers is more valuable than sorting by pressure alone.
Accessories can turn an average-looking pressure washer offer into a better fit for your home. Spray Guns and Pressure Washer Lances affect control and reach. Nozzles change the spray pattern. Hoses influence how far you can work without moving the machine. Brushes and Patio Cleaners help with specific surfaces.
For patios and paving, a dedicated patio cleaner can reduce splashback and cover flat areas more evenly than a narrow jet. If the washer you like does not include one, compare the price of adding a compatible patio cleaner before deciding.
For vehicles, a foam lance or detergent bottle may be more useful than a very high bar rating. The Draper Pressure Washer Snow Foam Lance is an example of an accessory that only makes sense if it fits your existing or chosen washer, so compatibility is essential.
For more awkward cleaning, such as garden furniture, conservatory frames or bins, a rotary brush or shorter lance can be handy. The Sealey PWA04 Rotary Brush is listed for specific Sealey models, which highlights an important point: accessories are often brand and model dependent, not universal.
Cordless pressure washers are worth considering when convenience, storage and portability are the priority. They can be useful away from an outdoor socket or tap depending on the model design, but you should check battery, water supply and pressure details carefully. They are usually bought for lighter cleaning rather than heavy-duty patio restoration.
Mains electric pressure washers are the common middle ground for many UK households. They are typically suited to cars, patios, decking, garden furniture and general exterior cleaning, provided the pressure, flow rate and accessories match the job.
Petrol pressure washers are more specialist. A product such as the Kärcher HD 9/25 G Classic Professional Petrol Pressure Washer, with 250 bar stated in the title, is aimed at a more demanding use case than quick home rinsing. Before choosing this type, consider handling, maintenance, storage and whether you need a machine of that scale.
A low headline price can be appealing, but it is only good value if the pressure washer suits the job and includes what you need. In the current Pressure Washers & Power Washers catalogue, some listings are complete machines while others are accessories such as trigger guns, hoses, brushes and patio cleaner heads. Compare like with like before judging value.
Check whether the listing is for the main pressure washer or a replacement part. The Draper Pressure Washer Trigger 83713, for instance, is not a complete washer. The Sealey GGH450 Rubber Delivery Hose is a hose rather than a pressure washer. These can be useful buys, but they should not be compared directly with full machines such as the Makita HW101, Draper 98674, Durhand High-Performance Portable Power Washer Jet Cleaner or Flymo EasiClean Li Plus.
Look beyond the discount label. A strong offer should have the right pressure range, adequate flow rate, compatible accessories, sensible storage needs and a retailer listing that clearly explains what is included. If the bundle lacks a patio cleaner, foam lance or extension hose you know you will need, factor that into the overall cost before choosing.
If you mainly clean bikes, tools and bins, prioritise portability, easy storage and simple set-up. A cordless or compact model may make more sense than a very powerful machine.
If you clean a car regularly, look for controllable pressure, suitable nozzles, detergent or foam options, and enough hose length to move around the vehicle comfortably.
If patios, paving and decking are the main jobs, compare bar, flow rate and patio cleaner compatibility together. The best match is often the model that covers ground efficiently rather than the one with the highest pressure number alone.
If you need frequent heavy-duty cleaning, compare higher-pressure machines carefully and make sure the power source, weight, maintenance needs and accessories match your expectations. A professional-style petrol pressure washer can be excessive for small domestic jobs, but appropriate for more demanding use cases.
They measure the same thing: pressure. UK listings often use bar, while some also show PSI. Use either to compare pressure, but also check flow rate, nozzle options, hose length and included accessories.
Patios usually benefit from a stronger pressure washer with a good flow rate, but a compatible patio cleaner attachment can be just as important. It helps cover flat surfaces more evenly and can reduce mess compared with a narrow jet.
Not usually. For cars, control and the right attachment matter more than maximum pressure. Look for suitable nozzles, detergent or foam options, and avoid using an aggressive jet too close to paintwork or trim.
Not always. Many lances, brushes, patio cleaners, spray guns and hoses are made for specific brands or models. Check compatibility carefully before buying an accessory separately.
First confirm whether the listing is a complete machine or an accessory. Then compare pressure, flow rate, power source, included tools, compatibility and overall value rather than relying only on the advertised discount.
The right pressure washer is the one that matches your cleaning jobs, not necessarily the one with the biggest bar or PSI figure. For light rinsing, portability may win. For cars, control and foam options matter. For patios, pressure, flow rate and a patio cleaner attachment are often the key combination.
When comparing Pressure Washers & Power Washers, check the complete offer: machine type, pressure rating, flow rate, hose length, lance, nozzles and accessories. That gives you a clearer view of value and helps you choose a model that will actually suit the way you clean.
