Electric vs petrol pressure washer: which is cheaper to own?
For driveways, patios and cars the two are worlds apart in both power and running cost. Most home jobs do not need the petrol machine — but where they do, nothing else will do. Here is the honest comparison.
- Only mains electricity to run — cheap per use
- Almost no servicing beyond cleaning and the odd seal
- Tied to a socket and a hose, and less powerful
- Plenty for cars, patios and most domestic cleaning
- Petrol and oil every use — an ongoing cost electric avoids
- Engine servicing: plugs, filters, oil, winter care
- Goes anywhere with no socket, and far more cleaning power
- Overkill and dearer to own for typical domestic jobs

For domestic cleaning — cars, patios, decking, driveways — an electric pressure washer is the clear lower true cost: cheap to buy, cheap to run and barely any servicing. A petrol machine is worth its higher cost only for large areas, off-grid use or heavy, professional-grade jobs where the extra power and portability genuinely earn their fuel and upkeep. For most homes, petrol is paying to own power you will rarely use.

Common questions
For home use, clearly — lower to buy, only electricity to run, and almost no servicing. A petrol washer costs more upfront and needs fuel, oil and engine care, so it is only cheaper to justify when you truly need its power and portability.
Rarely, for domestic jobs. Cars, patios and driveways are well within an electric machine’s power. Petrol earns its keep on large areas, off-grid work or professional-grade cleaning — otherwise you are paying to own and run power you will not use.
Petrol and oil for every use, plus engine servicing — spark plugs, filters, oil changes and winter care. These are the costs an electric model avoids, and they are why petrol is dearer to own for typical home cleaning.
