A Kirby shampoo tank that has cracked, clouded or started dumping solution instead of foaming turns a carpet clean into a soaking. This genuine Kirby tank assembly is the molded solution tank that snaps onto the shampooer head, holding the water and shampoo mix and metering it through the suds screen and sponge to produce the dry foam the system depends on.
Foam consistency is the whole point. Correct foam puts very little water into the pad, so carpets dry in hours rather than days. A tank with a stretched valve or split housing floods one area and leaves the rest untouched. The part also carries forward across generations, covering G3 through the Avalir, which means one tank suits a household or a shop that has more than one era of Kirby on hand.
Use cases
- Tank is cracked, crazed or permanently clouded and drips onto the carpet
- Solution empties in a single pass instead of metering into foam
- Replacing a tank that has clogged beyond recovery from never being rinsed
- Restoring the shampoo system on a Kirby that is otherwise complete
- Carpet care operators and repair shops servicing Kirby shampoo systems
Field notes
When a Kirby shampooer stops foaming, the tank is often not the culprit. The suds screen must face the shampooer rather than the tank; installed backwards it produces no suds and drains the tank rapidly, which is exactly what a failed tank looks like from the outside. A screen crusted with dried shampoo usually revives after a few hours soaking in vinegar and water.
Care determines how long a tank lasts. Rinse it after every use with warm water, never hot, and leave it open to air dry. Do not wipe the inside with paper towel or tissue, because the fibers stay behind and eventually clog the valve and suds screen. Tanks that are never rinsed clog beyond recovery and are the ones that end up being replaced.

Frequently asked questions
Does it fit my G4?
Yes. This tank covers G3 through G6 and continues through the Ultimate G, Sentria and Avalir machines.
Is part 306714 the same tank?
Yes. 306714 is the current Kirby number that supersedes 306799 and 306799S. It is the same tank.
Are the suds screen and sponge included?
Not always, and both must be present for the system to foam. Check the contents before ordering, and add them separately if your originals are damaged or clogged.
Why will my shampooer not foam?
Most often the suds screen is installed backwards or is clogged, or the valve under the sponge is blocked. The screen must face the shampooer, not the tank. A crusted screen usually revives after a few hours soaking in vinegar and water.
How should I care for the tank?
Rinse it after every use with warm water, never hot, and leave it open to air dry. Do not wipe the inside with paper towel or tissue, because the fibers stay behind and clog the valve and suds screen.
