Bissell Water Spinwave Tank Assembly

Water tank assembly for the Bissell SpinWave hard floor spin mop, part 1611570. This is the complete tank with its fittings, the reservoir the cleaning solution sits in, rather than a bare bottle.

Tanks come to grief in two places. A hairline crack, usually near a corner or around the neck, quietly empties the tank onto the floor while the machine is parked. Or the seal at the outlet hardens, at which point the pump draws air and the spray comes out in spits instead of a fan. Either way you find damp under the machine and dry patches on the floor behind it.

It fits the SpinWave 2039, 20391, 2039A, 2039T and 2039W. Empty and rinse it rather than leaving solution standing in it, because dried formula is what stiffens the seals in the first place.
