## Abstract

A double tentacle pump system for a liquid sprayer includes first and second tentacle pumps positioned serially within a flow path that extends between a liquid container and the outlet of the sprayer. A motor is configured to actuate the first and second tentacle motors in response to a user directed trigger, thereby causing fluid to be moved from the container and expelled from the sprayer.

## Claims

### Claim 1

A method for moving fluid through a singular fluid flow path extending from a container and through a sprayer for dispensing out of an outlet of the sprayer, comprising:
a. providing a first tentacle pump in the singular fluid flow path that is positioned to move fluid from the container into the sprayer;
b. providing a second tentacle pump in the singular fluid flow path at a position downstream of the first tentacle pump to move fluid towards the outlet; and
c. actuating the first and second tentacle pumps.

### Claim 2 (depends on 1)

The method according to claim 1 further comprising:
d. providing a shut-off valve positioned within the singular flow path.

### Claim 3 (depends on 2)

The method of claim 2 wherein the shut-off valve comprises a trigger configured to move the shutoff valve between open and closed positions.

### Claim 4 (depends on 3)

The method of claim 3 wherein the sprayer comprises a contact switch to which the shut-off valve moves into and out of electrical contact in response to the trigger moving the shut-off valve between its open and closed positions, respectively.

### Claim 5 (depends on 1)

The method of claim 1 wherein the first tentacle pump and the second tentacle pump each include at least one tentacle.
