The Wagan Tech OneVolt Cordless Polisher 6 Pro is a 6 inch dual action polisher with a 250W brushless motor, six digital speed settings from 2,300 to 4,800 RPM and a detachable U handle. It runs on 21V Max 3Ah lithium-ion batteries. Two batteries, a charger, four pads and a storage bag come in the kit.
It's made for detailing cars, boats and RVs and for finish work on furniture, when you want both hands on the tool.
An eccentric mechanism adds a 0.6 inch orbit to the pad's rotation for a dual action effect. Wagan designed this combined motion to create an even finish while helping prevent uneven heat buildup and swirl marks.
Press the + and - buttons to step through speeds 1 to 6, from 2,300 to 4,800 RPM. The panel shows the selected speed and the remaining battery level. The polisher always starts at speed 1, so you begin gently every time.
Engage the lock button to hold the ON/OFF trigger on for continuous operation. Press the trigger again to release the lock and stop.
The included U handle bolts on at the angle you prefer with the supplied Allen screws. Hold the rear grip with one hand and the U handle with the other, or use the front grip if you leave the handle off. Two hands help you keep pressure light and even.
Each 21V Max 3Ah (63Wh) battery gives more than 30 minutes of working time per full charge, and two come in the kit. Wagan describes them as UL-certified. The system protects against over-voltage, overcharging, overload, short circuit and reverse polarity, and charging pauses if a battery overheats.
Fine sandpaper, a sponge waxing pad, a microfiber wax-removing pad and a fluffy buffing pad press onto the hook and loop disc.
Automotive paint. Apply wax with the sponge pad, remove it with the microfiber pad and buff with the fluffy pad.
Boats and RVs. Polish exterior surfaces with no cord to manage.
Furniture and home surfaces. Refresh wood finishes and other surfaces, or use the fine sandpaper for light sanding.
Polishing by hand takes many passes and steady arm pressure. The Polisher 6 Pro's dual action pad does that work while you guide it slowly in vertical and horizontal passes.
A corded polisher ties you to an outlet. The 6 Pro moves freely around a vehicle or workspace, and you can switch to the second battery when the first runs low.
Wagan's manual says this polisher is intended only for dry polishing. Don't use it in the rain or with wet hands. Read your polishing compound's label to make sure it's suitable for machine use, and start with a small amount, since over-applying compound is the common mistake. Drawstring bonnets aren't recommended.
The manual says the included charger is designed only for this polisher's battery, and the battery shouldn't be charged on other chargers. A full charge takes 2 to 3 hours. Charge after each use and at least once a month in storage.
Wagan's manual rates each fully charged battery at more than 30 minutes of working time. Two batteries are included.
No. You can hold the rear grip and the front grip instead. The U handle gives you a secure two-handed grip if you want it.
Store the polisher with the backing pad facing up, and take the pads off when you're not using it. Hand wash the sponge and let it dry. Wipe the body with a damp cloth and mild detergent, and keep the ventilation louvers clear.
Wagan's manual lists a one-year limited warranty for the original purchaser against defects in material and workmanship.
The Wagan Tech OneVolt Cordless Polisher 6 Pro combines a brushless dual action drive, digital speed control, a U handle and two 21V batteries in one kit. If you'd like help choosing pads or planning a polishing project, the Outbound Power team is happy to help.
