New NSS CHARGER 2022DB Sulky 20" Walk-Behind Burnisher - 235Ah AGM Battery
Our Take (from the SES Sales Team)
“This is the Charger 2022 DB set up for long runs, with the ride-behind sulky included. It suits big schools, grocery stores, hospitals and retail floors where walking behind a burnisher for an entire shift wears people out. The machine spins a 20 in pad at 2,200 rpm with 70 lb of pad pressure, and NSS rates it at 24,000 sq ft per hour. A twist-grip throttle runs the wheel drive, so the operator steers instead of pushing, and the sulky flips up and stores on the handle when they need to walk it through a tight spot. This package runs on six 235 Ah AGM batteries, sealed with no watering, and the charger is on board so it plugs into any outlet. As a battery machine it has no fumes, no oil changes and no propane tanks to swap, and the Vac-Trac dust control captures the finish powder burnishing creates. At 68 dBA it is quiet enough to run while people are in the building.”
A 20 in wheel-drive battery burnisher with a ride-behind sulky
The NSS Charger 2022 DB is a 20 in battery burnisher that restores the wet-look gloss of floor finish without propane fumes or exhaust. A 2.5 hp, 36 V pad motor spins the pad at 2,200 rpm with 70 lb of pad pressure, a wheel drive with a twist-grip throttle moves the machine, and NSS rates it at 24,000 sq ft per hour.
This package adds the ride-behind sulky, so the operator can stand and ride on long runs instead of walking. It runs on six 6 V, 235 Ah AGM batteries with an onboard charger, so it plugs in at any standard outlet.

Questions
NSS Charger 2022 DB: common questions
How long does it run on a charge?
NSS publishes up to 2.7 hours for the Charger 2022 DB on 220 Ah AGM batteries and up to 3.0 hours on 235 Ah batteries. Actual runtime depends on the floor and how long the pad is down.
Do the AGM batteries need watering?
No. AGM batteries are sealed and maintenance free, with no cell caps to remove.
How does the sulky work?
The sulky is a platform behind the machine that the operator stands on and rides. When you need to walk the machine through tight spaces, it flips up and stores on the handle.
How much floor can it burnish in an hour?
NSS rates the Charger 2022 DB at 24,000 sq ft per hour.
Can it polish concrete?
Yes. NSS says the Charger 2022 motor is powerful enough for concrete polishing with diamond pads, as well as restoring the luster of floor finish after scrubbing.
