Buying Guide: Key Purchase Considerations
- Power and motor type: Brushless motors offer longer runtime and maintenance-free operation, while brushed motors can be simpler and cost-effective.
- Speed range and control: Look for models with multiple adjustable speeds (often 6–8) to match waxes, sealants, and paints. Check for LED displays showing RPM and battery status.
- Battery configuration: Dual batteries provide longer runtime; ensure you have compatible chargers and consider recharge time.
- Orbital throw and vibration: A typical dual-action polisher uses 8 mm to 15 mm throws. Smaller throws offer precise control; larger throws cover more area but require steadier hands.
- Accessories and kit contents: Pads, backing plates, wool and foam pads, and a carry case add value. A broader kit saves separate purchases.
- Ergonomics and weight: Side handles, top handles, and overall weight influence fatigue during extended sessions.
- Overheat protection: Automatic cool-down features protect both device and paint during long sessions.
Frequently Asked Questions
