I have a shark robot. Its only 5 months old n used it about 10 times. With all robots from shark the front brushes stop working . So i called n they told me its the motor. It will cost me 25 dollars for shipping. Now i gotten the shark from wallmart n will cost me nothing to rrturn it. Telling the shark operator that she still said to pay the 25 dollar shipping fee. I must tell everyone not to buy the shark robot cuz the front brushes not turning is a motor problem n that comming from the tech shark not to buy support User's recommendation: Not to buy the shark robot it will brake on the 10 time being used. N you have to pay to fix it.
