Tornado Tempest Roller Brush K47626420

The Tornado Tempest roller brush (part# K47626420) is the brushroll of the TV400-W26-U cordless wide-area sweeper — the part that actually does the cleaning. Tacony lists it as Roller Brush for Tornado Tempest Wide Area Carpet Sweeper. It is driven by the brush motor (part# K66135760) through the V-ribbed belt (part# K63480580) and pulley (part# K56250390), and runs in ball bearings (part# K44011980) at each end.

A sweeper brushroll does two jobs at once. Its bristles flex into the carpet pile and release the grit held down in it, and the rotation then throws that grit backward into the hopper. Both depend on bristle stiffness and length. As the bristles shorten and soften with use the brush stops reaching into the pile, and what the machine picks up quietly reduces to whatever was already loose on the surface — which looks like a suction problem and is not one.

Compatible Models for the Roller Brush

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

When to replace the roller brush

• Bristles are visibly shortened, splayed or bent over.
• Ground-in grit is being left behind while loose surface debris is picked up.
• Bristle rows are worn unevenly along the length of the roller.
• String, hair or carpet fibre is wound into the ends and cannot be cleared.
• The brush is out of balance, or its end fittings are damaged.

The second symptom is the diagnostic one. If the machine still picks up loose dirt but stopped lifting the ground-in soil it used to, the brush has lost its reach into the pile — and no amount of checking filters and seals will bring that back.

Fitting notes

Remove the battery pack before starting. The brush runs between the left and right plates (part# K50979430 and K50979420), on bearings in their flanges (part# K52530260), driven through the belt. Clear any wound fibre from the bearing housings while the brush is out and check the belt and bearings at the same time — a new brush on a glazed belt or a rough bearing will not deliver what it should. Check brush pressure at the height adjustment knob afterwards.

Frequently Asked Questions

What does the roller brush do on the Tornado Tempest?

It agitates the carpet pile to release ground-in grit and throws that debris backward into the hopper. It is the component that does the actual cleaning across the machine’s 26-inch path.

How do I know if my roller brush needs replacing?

The clearest sign is that the machine still picks up loose surface dirt but has stopped lifting ground-in soil — the bristles have lost their reach into the pile. Visibly shortened, splayed or unevenly worn bristles confirm it.

What models is the roller brush (part# K47626420) compatible with?

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

What else should I check when fitting a new brush?

The V-ribbed belt (part# K63480580) and the ball bearings (part# K44011980). A new brush on a glazed belt or a rough bearing will not perform, and both are far cheaper to do while the machine is already open.
