Should do no problem using the dirtblaster lance. My ageing Karcher 520M does the job great and is only a little more powerful than this one. You'll have to get close for tough spots.

Nothing more satisfying than pressure washing a patio. I need to get out more.

The price is good but karcher pressure washers do not last,I know this from personal experience,the pumps are plastic and fail/start to leak very quickly,they are all show and not much go.

Better off buying a nilfisk,they don't look as pretty as a karcher but they last !

is it national deal ?

Are these strong enough to clean down patio flagstones?

It's instore only. My local still has a few but I imagine at that price some stores may have sold out??

This is also available from B&Q for £48. But based upon the pictures, looks like you get more accessories with the Morrisons one.

The one in B&Q is a compact machine, the one in Morrison's looks a bit sturdier. Also you don't get the patio tool which saves so much time!

Same one at B&Q is £98

I've got one of these, paid the same price for a refurb direct from Karcher last year. excellent price for a brand new one.
