It's annoying when your cord doesn't quite reach where you need it to. You can pull and jig as much as you want, but the only outcome will be the loosening of the plug from its socket. And it seems that no matter how long the cable is for whatever you're using, it's precisely 10cm short of what you need it to be. This is especially true when it comes to cleaning your car.
Pressure washers and vacuum cleaners are a perfect way of cleaning your car, but unless you're prepared to risk a cordless, battery-operated example for your cleaning duties you'll be bound to the operating radius offered by the manufacturer. There's little point risking it with a normal extension lead (especially in the case of the pressure washer) because of how temperamental British weather can be. What you need for your pressure washer and vacuum cleaner is a proper, IP-certified waterproof extension lead.
What is IP?
IP stands for ingress protection and is a way of measuring how protected an electrical item is from solids (the first number) and liquids (the second number), so it's important to understand what to look for when you're after a waterproof extension lead.
As a rule of thumb, we say look for an IP54 rating for a domestic waterproof extension cord which means it's protected against dust that could damage other electronics and is watertight against any water splashes. In short, as long as you don't shoot it with the nozzle of your pressure water you'll be fine. Anything rated higher is better still, but will cost a bit more.
