I bought this for my husband who wanted a more powerful cordless vacuum cleaner. The good thing about this one is that it uses the same battery packs as the B&D tools it has. So if he runs out of power, he can just swap in another battery pack. The suction power isn't bad for a small vacuum, but the tank is very small and needs to be emptied frequently. He says the weight is ok, I would have preferred a lighter weight, but it's still not that bad. I would give five stars if the canister was better or if the suction was a little more.
