This model only works well for light, everyday vacuuming. I purchased it expecting it to be effective on pet hair. If there is any accumulation of pet hair (more than light shedding from 1-2 days), it repeatedly clogs and turns off. You have to stop and clean out the blockage, then start again. (Note that I only have 1 dog, and the shedding is not excessive.) It is lightweight, cordless, and the freestanding docking station are all excellent features - and it works well for daily, light vacuuming. However, it is useless for heavy duty cleaning. It is definitely not worth the high price.
