Operating time
Time of continuous operation of the battery sprayer (see "Type") on one battery charge. The actual operating time may differ slightly from the claimed one due to the specifics of a particular situation, however, these differences are usually not very large, and this indicator can be used to evaluate not only theoretical, but also practical indicators of battery life.
Spray lock
A device that allows you to fix the trigger (switch) of the sprayer in the pressed position. This is especially convenient for large volumes of work: holding the trigger manually for a long time is rather tiring, and
the continuous watering lock allows you to avoid unnecessary stress on your hands.
Note that this feature can be found in all types of sprayers (see above), including lever ones — many models with this type of action are equipped with both a pumping lever and a separate trigger that must be kept pressed during operation.
Wand holder
The presence
of a tube clamp in the design of the sprayer.
Such a latch is a set of special clips, usually installed directly on the tank. It greatly simplifies the storage and transportation of the device: the handset, usually, is placed as compactly as possible and at the same time securely. Yes, and during breaks in work, this feature can come in handy — fixing the tube in the retainer is more convenient and safer than putting it on the ground, holding it in your hands, etc.
Weight
The total weight of the sprayer. Specified without taking into account the liquid or powder in the working tank; at the same time, for battery models (see “Type”), usually, the weight is given with a complete battery, and for gasoline models, on the contrary, “dry” weight, without fuel in the tank.
