New Advance Advenger X2805C-C EcoFlex Four 310 Ah wet batteries, onboard charger and brushes
Our Take (from the SES Sales Team)
“Want a cylindrical rider without dedicating floor space to a separate charger? The Advenger X2805C-C is worth a look. The -C means the charger is built in, so the operator parks it near an outlet and plugs in. This package runs on four 310 Ah wet batteries, a good everyday fit for schools, healthcare facilities, retail stores and light industrial floors. Its red polypropylene cylindrical brushes turn at 900 rpm across a 28 in path, and three scrub pressure settings (60, 80 and 100 lb) let the operator match pressure to the job. With 28 gal solution and 29 gal recovery tanks, it gets up to 85 minutes of scrubbing per tankful and up to 39,424 sq ft per hour. EcoFlex is standard: water only for routine cleaning, a detergent level from the onboard cartridge for heavier soil, and a burst of power button for spots that need more. At 27.5 in wide with a 63 in aisle turn, it gets around tight buildings easily. Remember that the wet batteries need regular watering.”

Questions
Advance Advenger X2805C-C: common questions
What do the X and -C mean?
The X means the EcoFlex detergent system is installed. The -C means the charger is onboard.
Cylindrical or disc?
The X2805C uses cylindrical brushes at 900 rpm with 60 to 100 lb of scrub pressure. The disc X2805D uses two 14 in pad holders at 260 rpm with 90 to 220 lb. Both clean a 28 in path with the same tanks.
Do the batteries need maintenance?
Yes. Wet (flooded) batteries need their water level checked and topped up regularly. The 56601638 package uses maintenance-free AGM batteries instead.
How much floor can it clean in an hour?
Advance rates it at up to 39,424 sq ft per hour at its 3.12 mph maximum cleaning speed, with up to 85 minutes of scrubbing per tankful.
