Much difference between Nilfisk Core 150 vs Core 140 for removing fetilizer stains?

Hi, I am looking to get a pressure washer, mainly for cleaning the pavement and the patio areas, which has general muck on as well as staining from plant pots and I have also recently used miracle gro 4-1 on the grass, and some got on the pavement and has gone an orange colour in bits. That doesn't seem to be coming off with general cleaning, so seems like it might need something more, like a pressure washer?

I was looking at 2 washers, my general budget is around £200 don't mind paying a little more if it would be worth it.

The 2 I was looking at are:

Nilfisk Core 140 and Nilfisk Core 150

There is a 10 bar difference in pressure, and the Core 140 is about £190 and the Core 150 is £240.
For the type of cleaning I am doing, will I see much difference between the 2 in terms of cleaning?

Would both remove that Miracle gro staining, or would both likely not? And probably need chemicals?

The next Nilfisk up was the Excellent models, they started at 160 bar, I think these have a stronger water storage than the core models, not sure if that would make much difference to me, they are also over £300 to start.

Well Nilfisk are very good power washers, our old Nilfisk one failed after many years and now have a Core125 which does what we need.

However getting a pressure washer to remove subborn stains and old black algea marks is likely to give a disappointing result.

Suggest you power wash the area then treat those remaining stains with a suitable remover.
That can vary from things like various Vinergars, to Bleaches to commerical Algea and Stain removers, most of which need care when used next to a planted area as when its washed off it may damage or kill the plants and soil.

Don't forget using a washer too frequently results in the paving surface being deteriorated so it becomes dirty quicker, we only clean our paving a max of twice a year.

 

I think the main difference other than pressure is the 150 has a folding handle (to help storage, handy if space is tight) and a longer hose 10m vs 6m which is handy. I am looking at getting the 150 for these reasons.
