The Shark PowerDetect IP1251 is a cordless, bagless stick vacuum with HEPA filtration, designed for multi-surface cleaning on both carpets and hard floors. It features a DuoClean Detect nozzle that captures dirt, dust, and debris in both forward and reverse strokes, which reviewers note helps in cleaning faster. The vacuum includes PowerDetect technology that automatically adjusts suction power based on the amount of debris and floor type detected. It offers up to 70 minutes of runtime in ECO mode and utilizes MultiFLEX technology, which allows the wand to bend for easy cleaning under furniture or fold over for compact storage. This model is designed for pet hair removal and includes an Odor Neutralizer Technology feature to guard against bad odors. Note that some variants (like IP3251) come with an auto-empty dock, but the IP1251 is a standard manually-emptied model
