New Advance Advenger X2805C-C EcoFlex Four 312 Ah maint-free AGM batteries, onboard charger and brushes
Our Take (from the SES Sales Team)
“For a cylindrical rider that asks very little of the people who maintain it, this X2805C-C package is the one. Four 312 Ah AGM batteries are sealed and maintenance-free, and the charger is onboard, so the daily routine is just scrub, dump, rinse and plug in. That is a big plus for hospitals, schools, hotels and stores where several operators share one machine. The deck uses red polypropylene cylindrical brushes at 900 rpm across a 28 in path, with three scrub pressure settings from 60 to 100 lb. The 28 gal solution and 29 gal recovery tanks give up to 85 minutes of scrubbing per tankful, at up to 39,424 sq ft per hour. EcoFlex is standard, so the operator can run water only for light soil, add detergent from the cartridge when it is needed, and use burst of power on entryways or spills. It is 27.5 in wide, turns in a 63 in aisle and runs at 63.7 dB A, quiet enough for daytime cleaning.”
