Can I use hot water with Karcher pressure washers?

Karcher pressure washers are designed for specific applications, and their ability to handle hot water depends on the model. Generally, most residential Karcher models are intended for use with cold water only, while some commercial and industrial models are designed to accommodate hot water. Using hot water in pressure washers not specifically rated for it can potentially damage the internal components, void the warranty, and reduce the unit's effectiveness. For optimal performance, it is important to refer to the user manual for the specific Karcher model in question to understand its temperature limitations. If you are unsure or have further questions, it might be helpful to look on the Karcher website, where additional information and specifications can be found.
