Query: Its sure sucks.....literally and figuratively

We got this for a decent price and initially it seemed pretty good for the price. The self-cleaning duster option was a novel idea but failed to work well. It wasnt that good at dusting, and when the switch was flipped to clean it off, it didnt. I was disappointed.The big bummer was that it doesnt do well with pet hair. We TRIED to vacuum out our floor heater, but all the dog hair kept getting caught in the upper filter. This was VERY aggrevating.The bagless cup is also not very big and requires frequent changing.Look at another vacuum, do not waste your money on this.
