Tornado Tempest Main Cover K55170140

The Tornado Tempest main cover (part# K55170140) is the hinged top housing of the TV400-W26-U cordless wide-area sweeper. Tacony lists it as Main Cover, Tempest. It encloses the debris container and the filter chamber, seals against the machine body through its gasket (part# K53650830), and is what the operator lifts every time the hopper is emptied.

On a vacuum sweeper the cover is not just a lid. The machine develops its airflow by pulling through the filter and out of the blower, and that only works if the cover seals. A cover that is cracked, warped or no longer closing square lets air in at the wrong place, and the first symptom is not a visible gap — it is a machine that has quietly stopped picking up as well as it used to across the whole 26-inch path.

Compatible Models for the Main Cover

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

Symptoms that point to the main cover

• Pickup has fallen off across the full width with a clean filter and a good brush.
• The cover does not sit square, or one corner stands proud when latched.
• Visible cracks, especially around the hinge points or the strap anchor.
• The cover rattles or lifts at the front while the machine is running.
• Impact damage from the machine being knocked or dropped.

Before ordering a cover, check the gasket (part# K53650830) and the strap (part# K50200110). A perished gasket or a slack strap produces the same loss of suction at a small fraction of the cost.

Fitting notes

Remove the battery pack before starting. The cover pivots on two swivel-arm hinges (part# K50356100) secured with M5 x 35 screws (part# K73031100) and their washers (part# K73122820), and is held closed by the strap (part# K50200110) anchored through its fixing plate (part# K50074610). Transfer the gasket to the new cover, or fit a new one while the machine is open. Check the cover closes square and seals all round before returning the machine to service.

Frequently Asked Questions

What does the main cover do on the Tornado Tempest?

It encloses the debris container and filter chamber and seals the airflow path. The machine can only develop suction across its full cleaning width if the cover seals properly against its gasket.

How do I know if my main cover needs replacing?

Reduced pickup across the whole width with a clean filter and good brush, a cover that does not sit square or stands proud at one corner, or visible cracks around the hinges or strap anchor. Check the gasket and strap first — they are far cheaper and cause the same symptom.

What models is the main cover (part# K55170140) compatible with?

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

Should I replace the gasket at the same time?

Yes, if the machine has any age on it. The gasket (part# K53650830) is inexpensive, it is what actually makes the seal, and fitting a new cover onto a tired gasket wastes most of the benefit.
