New Advance Advenger X2805D-C EcoFlex Four 310 Ah wet batteries, onboard charger and pad holders
Our Take (from the SES Sales Team)
“The X2805D-C is the Advenger for buildings that do not have a dedicated charging room. The -C means the charger is onboard, so the operator parks the machine near an outlet and plugs it in, with no separate shelf charger to store or move around. This package uses four 310 Ah wet batteries, a solid middle ground for daily scrubbing in schools, clinics, retail stores and office buildings. It cleans a 28 in path with two 14 in pad holders at up to 39,424 sq ft per hour, and the 28 gal solution tank gives up to 85 minutes of scrubbing per fill. EcoFlex comes standard, letting operators run water only for maintenance cleaning and add detergent from the onboard cartridge only where the floor needs it. The body is just 27.5 in wide and turns in a 63 in aisle, and at 63.7 dB A it is quiet enough for daytime work around people. Keep in mind that wet batteries need regular watering.”
