system
You are a helpful assistant. The assistant first thinks about the reasoning process in the mind by using Belief-Desire-Intention (BDI) framework and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively. 
Below is an instruction that describes a task. After thinking, when you finally reach a conclusion based on the customer's intention, desire and belief, clearly state the BDI thinking process within <think> </think> and then the answer within <answer> </answer> tags.

User Review: Some aspects of this vacuum seem flimsy, but it has some really well thought out features and replaceable parts. I love the long hose and the little collar that adjusts the air flow. If you're vacuuming curtains or lightweight rugs, you can turn it to decrease the suction so it doesn't try to vacuum up the fabric. It has really good suction this is definitely a good thing to have. The hose is made of thinner plastic than I'm used to so you have to keep that in mind as you use the vacuum as it can and will kink.  There's a replacement hose that you can eventually get, though, and its reviews indicated it has better quality than the original.  I like the idea of being able to readily find replacement parts and the simplicity of the design of this vacuum. Changing the bag is super easy, I like that it doesn't have a cord rewind cuz those never really work very well (or at least for very long), and it's nice and small for storage. The crevice tool fits in the handle and the brush/upholstery tool fits on the end opposite of where the hose attaches. I like how that tool has two separate tube attachment points (so basically, like an eight shape) to direct suction to the brush side or the side without the brush. Most tools like this twist on the end to redirect suction from one side to the other, but I find it just as easy and a little less confusing to just pop the tool off of the one side and onto the other side. The tool also attaches to the body of the vacuum for storage using the double tube design. I've been using a different floor tool with my vacuum for the most part, but I really liked the design of the floor tool that came with the vacuum. It worked better than I imagined on my low pile rugs. It has a little foot lever to push a little row of bristles down in the front and then step on it again and they go away again to switch to hard floors.  I mostly have hard floors and I personally prefer a different type of floor tool, but this one seemed pretty nice to the extent that I used it.  As far as other comments people have made, the vacuum is a little loud and gets warm, but it's still in the range of average I think. Nothing too major. For the price, it's tough to beat. At some point I'm planning on ordering a 2nd one to use in my basement and garage :)
