Why it helps a lawn renovation
Long renovation spray days (lawn kill, broadleaf, fungicide) are easier when pressure stays steady without pumping. Same tank math as other 4 gal setups on this site.
How to use it
Charge before a big job; runtime is typically several hours depending on pressure and nozzle. Use the coverage-per-tank setting under My lawn. Rinse thoroughly — battery units still hold chemical residue in hose and wand.
