For instance do you want a hot or cold water pressure washer. In most situations a cold water version is adequate but a hot water washer with an integral boiler will remove stubborn residue more easily (just think about doing the washing up – hot water is much more effective). For even more cleaning power a hot water jet washer can have a facility to make steam which is achieved by a valve reducing the water flow into the boiler causing steam to be formed when leaving the lance. Steam is useful for cleaning very stubborn deposits as well as killing bacteria.
Floor Buffers and Polishers Floor buffers are typically used for cleaning hard floors such as hardwood marble tile or linoleum. The rotary brushes move over flat surfaces to dislodge dirt and dust. Floor buffers are also known as a floor polishers burnishers or buffing machines and are available in a range of sizes with different brush speeds to cater for a variety of flooring types and cleaning needs.
If an independent power source is needed which is not constrained by the electrical supply then a diesel or petrol engine model is the answer. This type of pressure washer can be more powerful than electric machines and is ideal for off site work. These machines are often mounted in a tubular steel frame for robustness.
