The difference between the "Hypresso 18/24-1 (battery-operated)" and the "Hypresso 18/24 Li-Solo" lies mainly in the title suffix "Li-Solo". Both devices are members of the Power X-Change family, operate with an 18 V battery, have a maximum pressure of 24 bar and a delivery rate of 240 l/h. The technical specifications and accessories are identical, including a 5 m suction hose, adjustable nozzle, foam spray bottle and splash water protection. The addition "Li-Solo" indicates that the device is supplied without a battery and charger, which is also the case with the other model. The price difference of 20 francs is therefore presumably a pricing without technical differences.
