The air compressor works just like a traditional air compressor that would be used to blow up a bicycle tire. When the air is pumped into the tank, it forces the liquid out of the lawn sprayer.

Since an air compressor-style pump is used, rather than the traditional manual hand-pump style, the air is mechanically forced down from above, without touching the liquid. This allows the user to use the same uncontaminated pump with several different tanks of chemicals (lawn fertilizer, weed killer, insect killer, etc.).

The Air Compressor Pump from the WG829 Cordless Lawn Sprayer also works with the WA4028 (5L) and WA4029 (2gal) WORX tank models that are sold separately to be used as spare tanks. In addition, the pump shares a common thread within the lawn sprayer market. As a result, this pump will work on many tanks from competitive manual-pump lawn and yard sprayers, including various Round Up®, Smith®, Husqvarna®, and Scotts® models.

No. The pump will initially run to pressurize the tank; once the tank is pressurized and the user starts spraying, the pump will kick back on for several seconds to ensure the pressure stays at a high enough level to maintain a steady spraying stream.

Length of sprayer wand without the nozzle is approximately 19.21 inches. 

Length of sprayer wand with the nozzle is approximately 21.65 inches 

The length of the hose is approximately 49.21 inches.

Hose material is PVC.
