The electric vacuums are cool but, IMO
, a bit of a maintenance redundancy because using a traditional vac cleans the substrate and drains the tank for a PWC
in one fell swoop. Considering that you already need a traditional vac to drain your water, an electronic vac just becomes yet another piece of gear and an additional expense. I get the appeal of the bells and whistles; I was intrigued by the Fluval electrovac at my LFS
the other day. But I can't justify spending the $50 when the purchase saves me zero time or effort. Most of us should be changing our water more anyway. Why add an extra step when you can drain and vac at the same time? Plus, a traditional vac leaves you no filter sock to clean and dry after; just toss out the old water which you have to do anyway when draining.
Pardon the pun but those new fangled electric vacs are for suckers! Stick to the $8 old school vac and a bucket and save the extra money for a cannister filter.
