Pressure washer - Clarke Hot Harry or Nilfisk 200 or ??

I’m needing to get a new pressure washer, something to clean the cars, driveway/yard etc and occasionally the drains.

I have always liked the idea of hot water pressure washer but they are big and expensive, machine mart have got an offer on at the minute with a hot Harry going for £600 inc vat. It’s not a true hot water pressure washer because it heats to around 70c rather than 130c+ like an industrial version.

The other option is a Nilfisk 200 premium, around the same money but more pressure (200bar vs 145bar). Does the addition of heat make up for the lack of ultimate pressure?

I’m wanting something decent that will last, my dad’s karcher k4 is on its 3rd rebuild so I don’t fancy one of them.

I’m open to other suggestions, I know kranzle seem decent but it looks more like it’s for car detailers rather than general use and I don’t know how good they are for driveway cleaning.

Petrol is an option too but it would have to have a half decent engine on it, I got fed up with the poorly made motor on my garden multi tool so I don’t want hassle every time I go to use it.

Thank you!
