As a result, I left the patio roof looking like an unfinished job. Again, that’s not a problem that’s exclusive to the Mac Allister 1,800W, but if you’re looking to buy a pressure washer for the purpose of cleaning your conservatory roof, you might want to reconsider. Mac Allister 1,800W review: Verdict The hardworking 1800W motor is looked after by water-cooling, so you can enjoy enhanced performance and a longer life. This machine also has a water inlet filter to prevent dirt particles from damaging the pump. On average, five and a half years passed before those who bought their corded pressure washer between 2015-2021 experienced the first fault out of a sample size of 3,203 people. Of those that reported a faulty product, 39% carried on using it as normal and 19% had it repaired by someone they know. Before looking at the pressure washer nozzle chart, an important point about pressure washers in general is that we measure its cleaning power in terms of Gallons per Minute or GPM. Inspect for leaks, holes or tears in your garden hose. If you find any, plug the holes or replace the hose.
In short, it’s best used for medium-sized cleaning tasks such as cleaning your car, wheelie bin, garden furniture, patio and more. For comparison, the 2,100W model (19.2kg) – which B&Q says is suited to cleaning larger patios, paths and garden stone walls – offers a maximum pressure of 140 bar and a 450l/h flow rate. Meanwhile, the low-end 1,300W model (9.6kg) gives you a 100-bar maximum pressure and a 390l/h flow rate. All three machines work with water up to a maximum temperature of 50 °C.

Apart from the engine/motor, there is a spray gun with a trigger and a nozzle at the end. The engine or motor will drive a pump to increase the incoming water pressure by several hundred times. Nozzle at the end of the spray gun directs this high-pressure spray on the surface. A power pressure washer will spray water in a more powerful stream than any standard hose could hope to accomplish. That is since it employs vitality to push the water out, whereas your hose utilizes the town or city supplied water pressure to push out water. This pressure is excellent for practical utilizes within the household, but is just not really excellent in case you require a robust shot of water. Because of this some own the power washer. They want the water to clean issues which you could ordinarily really have to scrub for hours using a typical water provide like a hose. If you rely on one nozzle the most, it may be that it has worn out. Attach a nozzle you use the least to see if the pressure increases. If it does, it may just mean it's time to replace your other one. The main flat-headed lance is designed for the majority of jobs because the pressure can be adjusted on the lance itself. It comes with four main settings – Mix, Soft, Medium and Hard. The Mix setting is mostly just water that’s ejected in a wide-ish arc. This is a good setting for sweeping mud off the patio, gently washing windows and pre-soaking the car. The Soft, Medium and Hard settings eject water mist at different levels of fineness. The Hard setting on the flat-headed lance is a good one to use for light patio cleaning but only if the nozzle tip is a few inches away from the surface. Any closer and it will perform a much deeper clean, albeit by just an inch or two at a time.
On the contrary, if you select a larger nozzle size, then you will compromise the cleaning ability by reducing the pressure. So, it is important that follow some guidelines set by the manufacturer to select the correct pressure washer nozzle.
