Don't bother with vacuums. They are expensive to buy, expensive to operate,
and waste a lot of water. The pond is balanced with some accumulation of
debris on the bottom for aquatic life, and the koi, as true bottom feeders,
like to root around in it. The debris is healthy. If you have a proper and
sizable filter, it should keep the pond crystal clear with leaves and
decaying grass on the bottom. I have a thirty-foot oval pond with a flat
three-foot bottom covering 1/3 of the pond area. There is a two-foot flat
level where I can walk and I walk it once a year in the fall with a
heavy-duty wire mesh on a long pole and I clean out all the debris. Takes
only a few hours and it is not necessary to get it spotless. The fish are
out of sight in the muddy water for about two days and then dthe water
clears up for the rest of the year. Good luck Linnette.....

Can anyone tell me if the one's operated by mains water pressure are
any
good. i.e. Do the job of clearing out the accumulation of muck and
leaves.
I am in the U.K. and these are on offer for £23.49 pp. I would be
grateful
for any views on these.
Thank you.

IMHO, they are a waste of time. I have very high water pressure and
found
that they pick up the leaves OK but not the muck. And keep in mind that
while you are using it, it's adding water to your pond. I use a wet-vac
now
instead.

I have a very basic hand operated pond vac that works just fine. It
does
remove water at the same time but that goes onto the garden so nothing is
wasted. A change of about a third of the pond water in the Spring if the
pump has been idle over winter is a good thing anyway.
