Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
Pressure Washer Help
To help determine the type of pressure washer required it is important to consider the size of your cleaning task and level of duty, i.e. how big is the cleaning object and how often will you need to clean it? Below is an explanation of the two main types of pressure washer. Whilst bar pressure is important the overriding factor in cleaning power is the water flow rate. More water = better cleaning.
Jargon Buster:
• Bar or PSI: Bar is the most common measure of pressure. PSI = bar x 14.5.
• Bar (max): This is the pressure achieved when the machine is first turned on
• Bar (rated) pressure: This is the operating water pressure of the machine.
• Motor size (kW): Motor size indicates power providing the machine runs efficiently.
• Flow Rate (l/h): Higher flow rates enable you to clean large areas or objects faster
Did You Know:
Pressure Washers use up to 80% less water than garden hosepipes.
Pressure Washers are not subject to hosepipe bans if used for safety reasons, or if a suction hose is used to pull water from a harvested source. i.e. not the water mains. They are also not subject to a ban if used for commercial reasons, for example to maintain cleanliness, hygiene or company image.
Important things to remember when using your pressure washer:
• Always use an RCD when using electrical products in connection with water.
• Never use a non-return valve at the pressure washer connection to a hose pipe.
• Never drive over or lay items on high pressure hoses to avoid damage.
• Your water supply hose should be a min of several meters long and unwound from its reel.
• If you are using an extension lead, check that it is rated at min of 13 amps and fully unwound from its reel.
