Mac allister Jet Nozzle for High Pressure Washer 13 mm

Product Information

Motor noise is typically less intrusive with these machines but they can be a little overpowered for many domestic cleaning jobs. Make sure you know how to use them properly to avoid damaging your surfaces. Nilfisk's entry level models tend to have more powerful motors and come with an aluminium pump head rather than a plastic one for durability. The first thing you need to consider when investing in a pressure washer is which area or outdoor items you’re looking to clean. This will determine how much pressure – measured in bars – you need your washer to have. Electric pressure washers are more suited to domestic cleaning, while petrol pressure washers are designed for professional, large-scale jobs. Best for: Cleaning extensive areas of paving, grimy 4-wheel drive vehicles, commercial vehicles and caravans

Pressure washers (also known as jet washers and power washers) deliver a powerful concentrated jet of water to remove dirt more efficiently than a brush, and using less water than you would with a garden hose. Basic machines come with one lance – a long tube with a nozzle at the end. A fixed lance can’t be adjusted, though you can move it nearer or further away from the area you’re trying to clean. You can also buy models with a variable pressure lance, where you can twist the nozzle at the end to alter the power of the spray – rather like a hosepipe attachment. This lets you create either a powerful narrow jet of water or a gentler, broad spray. 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. Hoses lengths vary from three metres, which is too short to wash a car; to five metres, which is an adequate length for car cleaning. Some of the cheaper pressure washers come with fixed nozzles that don't allow you to vary the water pressure. For the money, the Mac Allister 1,800W is undeniably a powerful machine. Having also tried out the more-expensive Kärcher K4 Full Control, I’d say the two machines blast away dirt with similar gusto.Although you have to be near a power outlet to use an electric washer, they are typically lighter, better for the environment, less noisy and will be powerful enough for the usual home and garden cleaning jobs.

Buying a new pressure washer can be confusing. There are usually several models in each manufacturer's range, with different types of motors and impenetrable model numbers which mean that useful accessories are either included in the price, or have to be bought as an extra. Best for: Cleaning small areas of lightly soiled paving, bicycles, small cars and garden furniture. Toolstation has electric and petrol pressure washers, some of which are bundled with a patio cleaner. For fences, dirty cars and cleaning grime off paving slabs, look for a model with 120 bars of pressure. Anything above this is best reserved for complete garden overhauls and other industrial outdoor tasks. Flow rate The shorter hose and low power can make cleaning slow and difficult, and the motors tend to be noisy. The parts also tend to be flimsy and prone to frost damage. Medium dutyThanks to their concentrated water jets, pressure washers will save you valuable hours on the most heavy-duty tasks, as well as being incredibly satisfying to use on dirt and grime. Patio cleaner attachment: circular plastic hoods with a brush around the bottom edge. Stops you having to stoop and helps ensure dirty water doesn't spray everywhere. If you just need a pressure washer for light cleaning, then most no-frills machines come with just one lance, which is a long tube with a nozzle on the end. The nozzle will usually provide variable pressure – when you twist the nozzle, you can adjust the spray from a powerful narrow jet to a more broad gentle fan. Nilfisk models are typically more lightweight compared to Karcher models. They are constructed with light materials to make them easier to move around. In the end, I abandoned the brushes in favour of the vario nozzle, twisting it to the high-powered pencil jet spray (it also offers a wider, gentler spray). The impact was immediate, and within moments all the ingrained mud, oil and bird poo was nowhere to be seen.
