I will start off by saying that I am a huge fan of the shark vacuum products. In fact I have had the canister pet shark vacuum for about five years and absolutely love it. The only reason why I decided to branch out and purchase a new vacuum was because of the new technology of the Fin. This was a huge incentive for me because my hair gets tangled up in the brush and every so often I spend a lot of time cutting my hair out of it. That said I am very disappointed with the new technology. Instead of sucking up debris it tends to spread it around at times it even spits it out the back which causes even more work. Very disappointing because I had such high hopes and love their other products. That said,  I do not recommend this cordless vac.
