The Shark PowerDetect Pet Clean & Empty IP3251EUT makes cleaning easier with the automatic emptying station. After cleaning, you can place the vacuum in the station where it empties the dust cup itself. This way, the dust stays in a closed dust cup and doesn't get into the air again. During cleaning, the PowerDetect technology automatically adjusts the suction power. The power increases with up to 75% in case of a lot of dirt or carpet. Thanks to the Reverse Clean technology, the floor brush works in both directions: forward and backward. The anti-tangle brush prevents hair from getting stuck. Thanks to the flexible Flexology tube, you can easily clean underneath low furniture. With a battery life up to 70 minutes, you can clean for a long time without charging it.
