It is getting to the time of year when the flagstones will be washed of
the winter grime and slime.

In the past I've used n ordinary pressure washer with a 'fanned' jet to
go over the paving (taking care to avoid the pointing between). As there
is c85sq m of paving to front, sides and rear I'm toying with the idea of
getting a washer with a 'patio' attachment (basically two spinning jets
enclosed within a bowl).

They *seem* to be more efficient in giving a more uniform clean and also
*seem* to offer a quicker option to clean such larger areas.

Can anyone offer any views on them from practical experience please?
Also any preference on makes/models from practical experience.

I've had Karcher in the past but had not been too happy with them so I'm
wondering about Nilfisk?

Google may be my friend but it does get very confusing!

TIA
