A petrol pressure washer cleans where there is no socket: farm yards, building sites, plant, horse boxes, long drives and the far end of a big garden. The engine powers the pump, so all you need is a water feed and a can of fuel.
We list 12 machines, from a compact 4HP Sealey for home use to Honda-engined Kärcher Professional models, two diesel pressure washers and a hot water unit. Just want a clean patio near the house? Our electric pressure washers are lighter and quieter. Every machine is sold by My Tool Shed.
Two reasons: no cable and more cleaning power. A petrol engine frees you from the extension lead, so you can wash a tractor in the field gateway, a digger on site or a caravan at the far end of a yard. And the pressure and flow are a step up. Most domestic electric machines give 100 to 150 bar and around 350 to 600 litres an hour. The petrol pressure washers on this page start at 150 bar and run up to 290 bar, with flow from 474 to 930 l/h.
Flow rate matters as much as pressure for cleaning speed. Bar breaks the dirt loose; litres per hour carry it away. That is why a petrol jet wash clears a mossy yard or caked mud far quicker than a mains machine with the same bar figure on the box.
The trade off: weight (20 to 175kg), noise, fumes and engine upkeep. A petrol power washer is an outdoor machine for big or remote jobs, not one to keep under the stairs.
Figures are the makers' maximums from our product pages. psi = bar x 14.5.

Prices move daily, but as a guide the Sealey and Draper machines sit between about £400 and £720, the Kärcher Classic range between £700 and £1,200, the Honda-engined Kärcher Professional models between £1,800 and £2,900, and the diesels from about £2,200 to £5,300.
For cars, vans and garden furniture, 150 bar is more than enough. For block paving, concrete yards and walls, 180 to 220 bar saves time. For plant, muck spreaders and dried concrete splash, 230 bar and up. A 4000psi petrol pressure washer means about 276 bar; two machines here go past that, the Sealey PWDM3600 at 290 bar and the Kärcher HD 9/25 G Classic at up to 300 bar. Our what bar pressure washer do I need guide matches bar to each job.
Read the flow rate in litres per hour, not just the bar or psi figure. The Draper's 474 l/h suits home jobs; the Kärcher HD 9/23 G's 930 l/h nearly doubles the rinsing speed on a big yard. More flow also means more water, so check your tap or tank can keep up.
Sealey and Draper use 141cc to 209cc four-stroke engines, fine for regular home and light trade use. Kärcher's Professional HD models use Honda GX engines and ceramic piston crankshaft pumps built for daily commercial and industrial hours. Low oil shutdown, which stops the engine before it seizes, comes on the Sealey PWM2500, PWM2500SP and PWDM3600.
Most start with a pull cord, like a lawnmower. The Sealey PWDM3600 has both electric and recoil start, and the Kärcher HD 9/23 DE and HDS 1000 BE have electric start, which helps with bigger engines.
A 5m hose means wheeling the machine around the job; 10m to 15m lets it stay put. The Sealey PWM2500 and PWDM3600 come with 0, 15, 25 and 40 degree fan nozzles plus a detergent nozzle. The Kärcher Professional models use the Easy!Force trigger gun, which cancels the recoil. Need more reach? See pressure washer extension hoses and turbo nozzles and dirt blasters.
The Sealey PWM1300 is the lightest at 20kg, with 150 bar and 576 l/h, and it suits a long drive, a patio far from the house or a vehicle on the yard. The Draper Expert PPW650 adds 186 bar, an 8m hose and a detergent tank. For patio work, pair either with one of our pressure washer patio cleaners.
220 bar from the Sealey or 200 bar and 700 l/h from the Kärcher. The Kärcher costs more, but its crankshaft pump is made for long hours, and at 36.2kg it fits in a van.
930 l/h and 230 bar from a Honda GX 390, or 250 bar working pressure from the Classic. Both shift caked mud and slurry, and the 15m hose on the HD 9/23 G keeps the machine clear of the spray.
A diesel pressure washer uses less fuel for the work and suits all-day running. The Sealey PWDM3600 burns 1.7 to 2.3 litres an hour from a 7 litre tank, and the Kärcher HD 9/23 DE uses a Yanmar engine. Both are 100kg plus, so they live on a trailer or in a yard. Since April 2022, most businesses can no longer run machines on red diesel; gov.uk sets out who still can, which includes agriculture.
The Kärcher HDS 1000 BE heats water up to 98°C with a burner, driven by a 13hp Honda petrol engine. Hot water cuts grease, oil and fat that cold water just smears, so it suits food yards, workshops and plant. See all of them on our hot water pressure washers page.
Not sure which way to go? What pressure washer should I buy walks through every type, and industrial and professional pressure washers lists the electric trade models too.
Kärcher lists the full Kärcher Professional pressure washer range, including spare parts and service kits. For the Kärcher models on this page, see our Kärcher Professional HD and HDS page; for the others, Sealey pressure washers and Draper pressure washers.
Every petrol pressure washer for sale on this page is sold by My Tool Shed. It sends most orders by courier, usually for next working day delivery, from £5.95, with a surcharge for the Highlands, the Islands and Northern Ireland. Unused items in their original packaging can go back within 30 days, with the buyer paying the return postage. Each machine carries its maker's warranty against manufacturing defects.
The Sealey PWM1300 for light jobs: 150 bar, 576 l/h and 20kg. For more power at home, the Draper Expert PPW650 at 186 bar with an 8m hose.
For daily trade use, yes. The Kärcher Professional HD models have ceramic piston crankshaft pumps and, on the HD 7/15 G and HD 9/23 G, Honda GX engines. For a few hours a month, a Sealey or Draper does the job for far less.
The Sealey PWM1300 uses 0.8 to 1 litre an hour from a 1 litre tank. The Sealey PWM2500 uses 2.1 to 2.6 litres an hour from a 4 litre tank. Bigger engines use more.
Some can. The Kärcher HD 7/15 G, HD 9/23 G and HD 9/23 DE self prime from ponds and tanks, and the Sealey PWM2500SP comes with a pick-up hose and filter. Others need a pressurised feed from a tap.
Yes, with care. Use a 25 or 40 degree fan, keep the lance 30cm or more from the paint and never use the 0 degree jet on panels or tyres. For cars alone, our pressure washers for cars are lighter and cheaper.
Yes. The Sealey PWDM3600 (diesel) reaches 290 bar, about 4,200psi, and the Karcher HD 9/25 G Classic gives up to 300 bar, about 4,350 psi.
