Tornado Tempest Main Skirt Plate K50979670

The Tornado Tempest main skirt plate (part# K50979670) is the clamping plate that holds the main skirt (part# K50321810) to the sweeping chamber on the TV400-W26-U cordless sweeper. Tacony lists it as Plate, Main Skirt. It is secured with five M5 x 16 screws (part# K73031070).

A skirt only works if it is clamped evenly along its whole length, and that is entirely the plate’s job. If the plate is bent, the clamping pressure varies from one screw to the next; the skirt is pinched in some places and loose in others, and it wears into a scalloped edge that stops sealing long before the rubber itself is worn out. A new skirt fitted under a bent plate will do the same thing again.

Compatible Models for the Main Skirt Plate

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

Symptoms that point to the skirt plate

• The skirt wears unevenly, scalloped rather than straight.
• The skirt works loose at one end while staying tight at the other.
• The plate is visibly bent, twisted or has elongated screw holes.
• A new skirt lost its seal unusually quickly.
• Screws in the plate will not stay tight.

Uneven skirt wear is the signature. If a skirt is worn to a wave rather than a straight line, look at the plate before fitting another one.

Fitting notes

Remove the battery pack before starting. Lay the plate on a flat surface before refitting and check it sits without rocking — a plate that has been overtightened at one end takes a permanent twist. Fit the skirt and plate together, running all five screws (part# K73031070) down finger-tight first, then tightening evenly from the centre outwards so the clamping pressure is uniform. Confirm the skirt contacts the floor along its full width afterwards.

Frequently Asked Questions

What does the main skirt plate do on the Tornado Tempest?

It clamps the main skirt evenly along its whole length against the sweeping chamber, which is what lets the skirt seal consistently to the floor.

How do I know if my skirt plate needs replacing?

Uneven or scalloped skirt wear is the classic sign, along with a skirt that works loose at one end, a visibly bent or twisted plate, or a new skirt that lost its seal quickly.

What models is the main skirt plate (part# K50979670) compatible with?

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

Should I replace the skirt and plate together?

If the skirt has worn unevenly, yes. A new skirt under a bent plate repeats the same wear pattern, and the plate is the part that caused it.
