To begin--yes, this product has excellent suction. Great for corners, couches, bare floors, curtains and stairs.
However, it is designed for low surfaces. Since it DOES say this in the product description, I shouldn't complain. It's just hard not to, because I have children who leave pretzle/chip/cereal crumbs around---and a son who, when he cleans the fish tank, drops pieces of the gravel on the floor.
This vacuum will NOT pick this stuff up at all. So, you will need to bend down and hand pick any "larger" items like this up yourself (unless you detach the vacuum head and suck it up with the wand. It's frustrating.
Great for some things......but for normal "daily living" stuff--it's not very functional (especially if you have kids). The only other problem I have is that the debris collects in just one small area of the canister, which prevents the "swirling" and leads me to believe the vacuum isn't doing as good of a job as it should be doing. This results in a LOT of canister dumping before it's actually anywhere near full.
I don't know, I'm thinking of returning it for another Dyson which is better for my needs.
