Hence the "" quotes surrounding "power".

(or an auxiliary pump for some) but the
robots do not have any plumbing.

That's got to make it tough to locate where to hook up "via the hose".

The robots are powered by a DC power
source via a cable.

The robots do a much better job of cleaning, especially for sand and
dirt. When I had a Polaris cleaner it picked up leaves just fine, but
finer pieces of debris like sand when right through the collection bag.

You ought to start a pool cleaning robot college, require Eng 101,
then take it.
