I've seen some portable pressure washers such as the V-Tuff been used but quite a few people.

I know this little machines pump out at around 12lpm, and that drops considerably when running at temperature.

So it would seem better to buy say a mazzoni hotbox that allows you to still use say 21lpm at temperature.

But my question Is we're and when would you need such a high flow with heat. With what I can see most only use heat when little pressure washing things like render, roofs, walls ect.

Is there ever a time people use heat on blockpaving ect then if yes then I would understand why the flow rate is needed.

Thanks

Flow is king

Why would you slow yourself down to 10 Litres per min when you can work at 21 litres per min and do the job over 2 times quicker - you maybe confusing flow with pressure

Block paving is simple and straightforward it can be done with cold - not so certain brick cleaning works
