I must say that the tracker bar pump I received today via an eBay
seller beats the vacuum cleaner hands down.  I had sucked out "some"
of the debris in the tracker bar hoses with a vacuum cleaner, but there
was still quite a bit in there.

This afternoon I tried the tracker bar pump.  Boy oh boy did that pump
get the dirt out of those hoses!  I was amazed at how effective the
tool was.  Several notes became more responsive immediately after the
process.  As far as I'm concerned, I won't be using a vacuum cleaner
for that job anymore.

 [ The tracker bar suction pump is a positive displacement pump much

 [ in a household vacuum cleaner.  -- Robbie
