Pros: Powerful and lasts a long time.
Cons: Does not actually trap dust.
I purchased this dust buster after we got a pet bird who kept flicking seed all over the tile floor. The price was right, the power was right and the size was right.
I used this everyday to clean up after the bird. It did a great job! It was almost fun switching the speeds from high to low and sucking up that crazy bird seed (I know, I need to get out more). Well, after a few months, it started spraying dust out of the vents when I turned it on. I took the filter out and cleaned it but it happened again. It still works great on bird seed, cat food, dirt, rocks, cheerios.....okay it works great on little things on the floor. What I discovered is that the filter that holds all the stuff does not actually hold dust or fine particles. Instead it blows right through the filter and back into the air. I have gotten a few "face fuls" of dust when I turn it on!
I like the fact that it is affordable, its powerful, it works for a long time before needing a recharge, it has 2 speeds and its convenient.
I don't like the fact that it gives my dust back to me. Poo! Needs a finer filter! Works great on cleaning up after pets and kids but it regurgitates dust from the vents. We only use ours in the garage to clean up kitty litter tracks for this reason. I would recommend this to people with kids and pets but don't actually expect it to bust your dust.
