A pressure washer's usefulness comes down to its balance of pressure, flow rate and the attachments it ships with, not just the headline bar figure. This guide compares washers tested by Expert Reviews on assembly, ease of use, cleaning power and value for money.

Best for cars and bikes
Nilfisk Core 130 Bike & Auto
Expert Reviews found this well-built and high-performance, bundling a wide-angled bodywork nozzle, soft car brush, under-chassis nozzle and foam sprayer that would normally cost another £40-50 separately. There's quite a lot of assembly involved and the warranty is shorter than some rivals.

Best cheap
Bosch EasyAquatak 110
A compact, suitcase-style washer that Expert Reviews found surprisingly powerful for its size and specs, easily removing caked-on grime from car bodywork and clearing moss from concrete. It's simple to operate with a single on/off switch, though the flow rate isn't enough for really big jobs.

Cons
- Not enough power or flow rate for bigger jobs
Best cheap Kärcher
Kärcher K2 Horizontal
Kärcher's entry-level washer, smaller even than the Bosch EasyAquatak, with smart storage features including a wind-round cable space and lock points for the trigger gun. Expert Reviews found enough power for cars and patios, though the single non-variable spray and short 3m hose limit versatility.
- Weight
- 3.5kg
- Max pressure
- 110 bar
- Flow rate
- 360l/hr
- Hose length
- 3m
- Motor power
- 1,400W

Pros
- Compact design with smart storage
- Effective cleaning for its size
- Upgradeable with Kärcher's accessory range
Cons
- Short hose and power cable
- Limited pressure and only a single spray pattern
Best budget value
Halfords PW20
A tiny price tag that belies genuine quality, according to Expert Reviews, blasting brake dust from alloy wheels and clearing algae from a patio, with a snow foam bottle included even at this price. It's louder and heavier than similarly-priced rivals, and has the lowest flow rate on test.
- Weight
- 6.3kg
- Max pressure
- 115 bar
- Flow rate
- 300l/hr
- Hose length
- 5m
- Motor power
- 1,600W
- Warranty
- 1 year
Pros
- Reasonably powerful for the price
- Snow foam bottle included
- Easy metal hose fittings
Cons
- Louder than rivals
- Relatively heavy
- Lowest flow rate on test
Best for car cleaning value
Ryobi 130 Electric Pressure Washer
Unlike rivals that need a separate detergent bottle, this has a built-in 0.9l tank you activate by twisting the lance, making car shampooing quick and even. Expert Reviews found the steel-braided hose resists tangling well, with only a fiddly hose release catch as a real criticism.
- Weight
- 8.3kg
- Max pressure
- 130 bar
- Flow rate
- 420l/hr
- Hose length
- 5m
- Motor power
- 1,600W
- Warranty
- 3 years
Pros
- Built-in detergent tank for easy car shampooing
- Vario lance adjusts from spot spray to fan
- Steel-braided hose resists tangling
Cons
- Not vastly cheaper than the more powerful Nilfisk Core 130
Best smart
Kärcher K5 Premium Smart Control
The bigger, more powerful, Bluetooth-enabled version of the K4, with a genuinely useful smartphone app and even more adjustability on its lance. Expert Reviews was seriously impressed by the balance of grime-defeating power and all-round ease of use, at a premium price.
- Connectivity
- Bluetooth with smartphone app
- Compatibility
- All Kärcher accessories
Pros
- Genuinely useful smartphone app
- Impressive balance of power and ease of use
- Compatible with the full Kärcher accessory range
Cons
- Premium price
Buying guide
What pressure (bar) do I actually need?
For cars, bikes and general patio cleaning, 100-130 bar is plenty and less likely to damage paintwork or soft surfaces. Higher pressure mainly helps with larger areas or stubborn ground-in dirt, but flow rate (how much water is delivered) matters just as much as peak pressure for how quickly a job gets done.
Does flow rate matter as much as pressure?
Yes. A higher flow rate (measured in litres per hour) clears a given area faster, since it's moving more water rather than just hitting it harder. A washer with high pressure but low flow rate, common on cheaper models, can still take a long time on bigger jobs like driveways.
What accessories are actually useful?
A foam nozzle or detergent tank is useful for car shampooing, a rotating brush helps with wheels and bodywork without scratching, and a surface cleaner attachment (like Kärcher's T5) speeds up flat areas like patios and driveways significantly compared to a standard lance.
Is a smart, app-connected pressure washer worth it?
An app-connected model like the Kärcher K5 here adds convenience for monitoring and adjusting settings, but it's a nice-to-have rather than essential. A simpler manual model with a good adjustable lance, like the K4 Power Control, gives most of the practical benefit at a lower price.
