Helio LX holds 5.8 gallons in a collapsible ground-standing reservoir and uses a foot pump to maintain seven to ten minutes of steady spray. NEMO explicitly lists washing a dog and muddy paws among its uses, and the seven-foot hose reaches around a medium or large dog without hanging the tank. It provides more water than the electric pumps without battery dependence, but a filled reservoir is heavy, the current official page has conflicting stock controls, and the purchase path relies on a low-stock authorized retailer.
