I like the idea of the Lupe. However, it's really difficult to see when the dust bin is full. I would suggest, make it clear. There's just no way at a glance to tell it's full. You have to stop, and kneel down to see that it's full. And the latch do open the dust bin to empty it -- needs to be redesigned. I have to constantly fiddle with it to open. Other's like the Dyson, open easily. Also, there's no motorized attachment for rugs. Dyson, Miele (all in the same price) offer a motorized attachment that allows you to work on rugs. Trying the Lupe on rugs is a nightmare. Doesn't work at all. Also, I read reviews on it's power to suck up items from carpet. Even on high, it just doesn't seem to hold fast to the carpet. With the Dyson or Miele, If I put it on high, I can barely move it across the carpet because the suction is so strong. On the Lupe, doesn't really feel like the suction is doing all that much. Fix all of these items and I think you'd have a great unit. Right now, great idea -- just poor execution.
