Query: No longevity, ni-cad battery won't last.

I was looking for a powerful dustbuster and this vac filled my needs when I got it. The problem is the battery eventually will not hold a charge and it seems that every-time I go and get it to clean a small spill, the battery is almost dead and the power is dismal. Too expensive for what you get and should have been a lithium ion, not ni-cad. Really not a recommended buy.
