Overall, I enjoy using my DC44. I have a house full of laminate flooring and hated sweeping, so this was a welcome change. I love that it's cordless so I can take it up and down the stairs with ease. I love the different attachments, especially the dusting brush. I love that it can clean my entire home in one pass. However, there are some cons:
1. It's a bit on the heavy side. With the motor in your hand, you support most of its weight and, while it's not substantial, it gets heavy after a while.
2. I wish it had a larger vacuum head. I feel like I have to make a million passes to do the whole room.
3. It needs an option for continuous suction (on). Right now you have to squeeze and hold a trigger to make the vacuum go, and my hand gets tired after about half of my square footage.
I haven't had it long enough to comment about cleaning filters, but the rotator brush cleans easily and the collection bowl empties easily as well.
So, great idea that could be improved upon, but overall 4 stars.
