Stihl RE 142 PLUS
Best OverallPros
- Honda engine is bulletproof and easy to service
- Excellent build quality from Stihl
- Low vibration and quiet operation
Cons
- Heavy at 28 kg
- Premium price point
The Stihl RE 142 PLUS is the petrol pressure washer that Bosch would build if they made them. It uses the legendary Honda GX160 engine, known for its reliability and long life. Owner reviews consistently praise its consistent pressure output and easy starting, even after long storage periods.
With 140 bar pressure and 500 L/h flow, it handles everything from car washing to patio cleaning. The frame is sturdy with large wheels for mobility. While the price is higher than budget options, the build quality and engine reliability justify the investment for frequent users.
Karcher G 2500 KH
Best Heavy-DutyPros
- Very high pressure for tough grime
- Karcher brand reliability
- Good parts availability
Cons
- Very heavy and bulky
- Engine can be hard to start in cold weather
The Karcher G 2500 KH is a commercial-grade machine aimed at heavy tasks like stripping paint or cleaning concrete. Its 250 bar pressure is among the highest in its class. Owner reviews highlight its cleaning speed but note the weight makes it a two-person job to load into a vehicle.
The pump is Karcher's own design, which means replacement parts are widely available. However, the engine is not a Honda, and some users report starting issues in cold conditions. It is best suited for professional landscapers or homeowners with large, heavily soiled areas.
Hyundai HY5100
Best BudgetPros
- Very high pressure for the price
- Reliable 212cc engine
- Good warranty support
Cons
- Pump is not as durable as Honda units
- Plastic components feel less premium
The Hyundai HY5100 offers exceptional value for money. It produces 5100 PSI, which is more than enough for any domestic task. The 212cc engine is a generic but reliable OHV design used in many budget machines. Owner reviews on Amazon and retailer sites give it 4.4 stars, with most complaints being about plastic fittings.
For the price, it is hard to beat. It comes with a 2-year warranty and Hyundai's UK-based support. However, the pump is not serviceable like the Stihl's, so if it fails, a replacement unit is needed. It is ideal for occasional heavy use where budget is the main concern.
Einhell TC-PW 2100
Best Light DIYPros
- Lightweight and easy to move
- Low price point
- Good for occasional patio cleaning
Cons
- Lower pressure than competitors
- Plastic pump housing is fragile
The Einhell TC-PW 2100 is a budget-friendly petrol washer for light DIY tasks. It is significantly lighter than the Stihl or Karcher, making it easy to transport. The 196cc engine starts reliably and is simple to maintain. Owner reviews rate it 4.2 stars, with praise for its value but criticism of the plastic pump housing.
It is not designed for heavy daily use. The pressure is adequate for cleaning cars, patios, and garden furniture, but it struggles with stubborn oil stains or old paint. For occasional users who want petrol freedom without the premium price, it is a solid choice.
Sealey 2100PSI
Best CompactPros
- Compact and relatively light
- Good build quality for the price
- Easy to store
Cons
- Lower flow rate
- Not as powerful as larger models
The Sealey 2100PSI is a compact petrol pressure washer designed for easy transport and storage. It features a 6.5HP engine and a lightweight frame at just 20 kg. Owner reviews highlight its portability and reliable starting, making it a good choice for mobile cleaning or small workshops.
It is not as powerful as the Stihl or Karcher, but for most domestic tasks it is sufficient. The lower flow rate means it takes longer to clean large areas. Sealey is a known brand in the UK tool market, and parts are available. It is a practical middle-ground option.
What to check before buying a petrol pressure washer
Pressure (bar/PSI) determines cleaning power. For cars and light patios, 100-150 bar is enough. For stripping paint or concrete, look for 200 bar or more. Flow rate (L/h) affects cleaning speed. Higher flow means faster rinsing but uses more water. Engine quality matters. Honda engines are the gold standard for reliability and serviceability. Cheaper engines may save money upfront but often fail sooner. Weight and portability are important if you need to move the machine around a property or load it into a vehicle. Look for large wheels and a sturdy frame. Pump type is critical. Wobble plate pumps are cheaper but less durable. Axial cam pumps (like those on Stihl and Karcher) last longer and are serviceable.
Mistakes to avoid when choosing a petrol pressure washer
Buying too much pressure for your needs. High-pressure machines can damage car paint, wood, and soft surfaces if used incorrectly. Ignoring pump quality. A cheap pump will fail long before the engine does. Always check if the pump is serviceable. Forgetting about noise. Petrol washers are loud. Check the decibel rating if you have close neighbours. Not considering fuel type. Most use unleaded petrol. Some require mixed oil. Check the specifications. Overlooking warranty and parts availability. Brands like Stihl and Karcher have extensive dealer networks. Budget brands may have limited support.

Our verdict
The Stihl RE 142 PLUS is the best Bosch alternative for a petrol pressure washer, offering German engineering and a Honda engine. For those on a budget, the Hyundai HY5100 provides excellent pressure at a low cost. If you need maximum power for heavy-duty work, the Karcher G 2500 KH is the top choice.
