I really like this Bissell Symphony to vacuum and steam mop my floor. I got it very fast with 4 mops inside the box. The machine is easy to assemble and light weight. The power cord is long enough to move around a large room. You don't need any solution, you just need water. When you use the mop with the scent disc, you room smell very nice for a long time but you don't really need to use it in case of allergy or asthma. The other positive thing, you don't need too much effort to use this machine because the machine is so light.
