Every cleaning session requires at least one press of this latch — over time the plastic tab fatigues and snaps, leaving the canister unable to lock back onto the vacuum body. Shark does not sell this latch button as a standalone part. The only official replacement is the entire dust canister assembly at $30–40. This printed latch restores full function at a fraction of that cost.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatible Models\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eShark FLEX DuoClean HV390\u003c\/li\u003e\n\u003cli\u003eShark FLEX DuoClean HV391\u003c\/li\u003e\n\u003cli\u003eShark Rocket DuoClean Ultralight (HV390 series)\u003c\/li\u003e\n\u003cli\u003eCross-Reference OEM Part Numbers\u003c\/li\u003e\n\u003cli\u003eShark HV390 \/ HV391 dust canister latch (no published standalone OEM part number)\u003c\/li\u003e\n\u003cli\u003eShark, FLEX, DuoClean, and Rocket are trademarks of SharkNinja Operating LLC.
