Shark Stratos Cordless IZ862H vs PowerDetect Speed Clean & Empty IA3241

The Shark PowerDetect Speed Clean & Empty IA3241 and the Shark Stratos Cordless IZ862H are both cordless stick vacuums from Shark, but the Stratos Cordless is the better overall pick. It offers better cleaning performance across the board due to its higher suction power, which enables it to lift dirt from cracks and high-pile carpets. The Stratos also keeps noticeably more dust contained in the air while you're actively cleaning, though both vacuums kick up a cloud of dust when it's time to empty them. The PowerDetect Speed's primary advantage is that it comes with a dock that empties its dustbin and keeps it charged automatically between cleaning sessions, so you'll rarely need to handle the bin yourself.
