This is an excellent cord free vacuum with the most suction and the longest battery life of any cordless vacuum I have ever used, which includes both high level Dyson and Shark vacuums. The Lupe is a bit heavier and as a consequence slightly less maneuverable than some of the competition, but the differences on that score are marginal and more than made up for by the Lupe's vacuuming power and long battery life. It is still much, much easier to use than any corded vacuum. I have not owned the vacuum long enough to judge its long term reliability or the longevity of the (ability to hold a charge) of its battery, but I am optimistic. For now I judge this vacuum a worthwhile investment.
