I found that the kitchen is more of a horizontal-surface cleaning environment, while the bath is more of a vertical-surface environment. This is important, because a Trigger Sprayer(KEXON) interacts differently with the hand depending on the type of surface to be cleaned. And different trigger/grip configurations seem more conducive to each environment.

Some bottles feature a protruding flange in the back of the spray head that asks users to carry the weight on the back of the hand. Others expect the bulk of the weight to be carried in the grip, where the fingers and palm meet the bottle neck.

For instance, in spraying a horizontal surface like a kitchen counter, the nozzle must pivot down. To achieve this angle, the weight of the bottle must be swung like a pendulum, up and away. I found that weight on the back of the hand, via the flange, allows users’ fingers more freedom to pull the bottle back and point it down without straining the wrist.

In spraying a vertical surface like a shower stall in the bathroom, the opposite seems to be true. Pointing the nozzle upward requires pressure on the palm of the hand against the rear neck of the bottle. Deep contours in the forward neck seem to help consumers carry the weight on the gripping fingers best; a few users also appreciated the texture and contours on the back of some bottle necks.

But, it’s important to point out that this configuration makes spraying a horizontal surface more difficult, because fingers must not only carry and swing the weight but also activate the trigger. And, in the same way, asking the weight to be placed on the back of the hand when spraying a vertical surface appears less effective, since the palm is best suited to swing the bottle upward.

Why is any of this important? Because a key learning is that, as a trigger sprayer configuration takes on more locations, tasks and surfaces, it may not perform optimally in each. This awareness is compounded by a few other situational differences regarding the spray action itself.
