Tornado Tempest Hopper K50321860

The Tornado Tempest hopper (part# K50321860) is the debris container of the TV400-W26-U cordless wide-area sweeper. Tacony lists it as Hopper, Tempest and the parts book as the Sweep Tank. It is the moulding the brush throws debris into, the part the operator lifts out to empty, and the part a disposable bin liner (part# K28843580) sits inside.

It leads a harder life than its simple shape suggests. Grit is thrown into it at speed all day, it is lifted and knocked out over a bin repeatedly, and it has to keep sealing against the machine each time it goes back in. A cracked or distorted hopper does not just risk spilling — it breaks the air path, and the machine loses suction across the full sweeping width.

Compatible Models for the Hopper

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

Symptoms that point to the hopper

• Cracks, splits or impact damage, particularly around the lifting points.
• Debris escaping around the hopper while sweeping.
• The hopper no longer seats squarely or is hard to latch home.
• Reduced pickup with a clean filter, good brush and sound cover gasket.
• Distortion that stops a bin liner sitting properly inside.

Fitting notes

Remove the battery pack before starting. The hopper works with its release lever (part# K50321830) and spring (part# K53321850), and the debris bag clamp assembly (part# K50978040 with its sleeve, screw and nut) retains the liner. Transfer those parts to the new hopper, checking the release lever operates cleanly before refitting. Seat the hopper and confirm it latches squarely and seals before returning the machine to service.

Frequently Asked Questions

What does the hopper do on the Tornado Tempest?

It is the debris container. The brushroll throws sweepings into it, it holds the disposable bin liner, and it forms part of the machine’s sealed air path — so it affects suction as well as capacity.

How do I know if my hopper needs replacing?

Cracks or splits, especially at the lifting points; debris escaping while sweeping; a hopper that no longer seats squarely; or reduced pickup when the filter, brush and cover gasket are all sound.

What models is the hopper (part# K50321860) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone.

Do I need bin liners for the hopper?

They are optional but recommended — the disposable bin liner bags (part# K28843580, ten per pack) keep the hopper clean and make emptying quicker and less dusty. The bag clamp assembly holds them in place.
