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!

A subject often discussed in uk.d-i-y. You should get a lot of answers
if you repost there.

I'll try adding it - hopefully it will work.

I have a Karcher TRacer head for mine... it makes the job quite a bit
easier since you are not carrying the weight of the jet or trying to
control it - it becomes more like toting an upright vacuum cleaner
about. A nice bonus is you end up wearing slightly somewhat less of the
crud you wash off!

Good timing for me, I was just thinking about investigating / shopping.
Presumably they are a bit more benign towards pointing than a standard
lance? Also, I'm interested in opinions about using bleach or other
cleaning products. Have grown quite a lot of algae on the new (cheap
Indian sandstone) slabs this winter, especially in the areas which don't
see so much direct sun.

I wouldn't use bleach. When our concrete back steps get slippery with
algae I use Jeyes fluid, elbow greas, a scrubbing brush, and rince with
hose.

Years ago I borrowed a neighbour's karcher pressure cleaner to clean
the concrete and it did no end of damage to the surface. Never again.
