Buying guide: how to choose your pressure washer

Choosing a pressure washer balances power and practicality. Pressure and flow rate determine cleaning effectiveness on different surfaces, while working range and noise level directly influence operating comfort.

What to check

Working pressure Maximum pressure, measured in bars, determines the washer’s ability to remove stubborn dirt. The higher this value, the more effectively the unit tackles heavily soiled surfaces like patios, facades or driveways. Across six recent market listings, pressure ranges from one hundred and forty bars for less powerful models to one hundred and seventy bars for top performers, with a median of one hundred and fifty-five bars. The score displayed on each product page immediately positions the pressure level against these market benchmarks. Market median: 155 bar

Water flow rate Maximum flow rate, expressed in litres per hour, directly influences how quickly you can clean large areas. High flow rates let you cover more ground in less time, which becomes decisive for extensive cleaning tasks. Market models show flow rates ranging from four hundred and twenty litres per hour for modest units to four hundred and fifty litres per hour for the most generous, with the median at four hundred and thirty-five litres per hour. This criterion combines with pressure to determine overall cleaning efficiency. Market median: 435 l/h

Working range Hose length determines your freedom of movement around the unit. The longer the hose, the less you need to interrupt work to reposition the machine. This matters particularly when cleaning vehicles, facades or areas far from the power supply. Hoses measure from five metres for compact models to ten metres for best-equipped units, with a median of seven metres. The score reflects this range and helps you choose according to your typical cleaning areas. Market median: 7 m

Noise level Sound power level, measured in decibels, affects your comfort and that of neighbours. The lower this value, the more bearable the unit remains during extended sessions. Market pressure washers range between eighty-nine and ninety decibels, with a median of eighty-nine point five decibels. These differences may seem minor, but every decibel counts for protecting your hearing and maintaining good neighbourly relations. The score rewards the quietest units. Market median: 89.5 dB

Power supply and storage Check the power cable length, which complements the working range offered by the hose. Too short a cable forces you to use multiple extension leads or frequently reposition the unit. Consider also accessory storage: nozzles, lances and hoses need dedicated space on the unit or in storage. Models with integrated hooks, holders and compartments simplify storage and prevent loss. Organised storage also extends accessory life by protecting them from impacts.
