Shark Wz250 Stick Vacuum Review. The shark ix141 is a cordless stick vacuum that has some similar features to the wz240, such as suction control and a lightweight build. The shark cordless pro has just about everything you’d want in a vacuum.

The big issue plaguing cordless vacuums atm is that the batteries have a very limited lifespan compared to a similarly priced corded model. Measured at the hand vac in standard.
