The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The RYOBI 5133004845 stands out in the cordless polisher category for its 7500 RPM top speed, the highest among the battery-powered options reviewed here. Running on RYOBI's 18V ONE+ platform, it keeps battery costs manageable for anyone already invested in that ecosystem. The tool weighs 2.2 kilograms (approximately 4.85 pounds), which is relatively light for the RPM class and helps reduce arm fatigue during extended polishing sessions.
At $211.40 it occupies the mid-to-high range of the cordless polisher market, positioned well below the DEWALT DCM848B but above entry-level picks like the CRAFTSMAN CMCE100B. The 4.6-star average from 344 reviews supports the performance claims the specs suggest.
Buyers who need aggressive paint correction capability in a cordless format will find the 7500 RPM ceiling genuinely useful. The trade-off, as with all battery polishers at this speed, is that high-RPM work drains battery packs faster, so having a spare battery on hand for longer jobs is a practical consideration.
Pros
- 7500 RPM top speed is the highest of the cordless polishers in this category grouping
- 4.6-star rating from 344 reviews confirms solid owner satisfaction

- Runs on RYOBI ONE+ 18V platform, compatible with a broad range of existing tools
Cons
- At $211.40 (tool only), total cost rises with battery and charger if not already owned
- High RPM at 7500 means faster battery drain on aggressive passes
- Spec sheet does not publish pad size or orbit diameter

Performance notes
Powered by an 18V RYOBI battery, the 5133004845 reaches 7500 RPM, enabling both finishing and more demanding correction work. At 2.2 kilograms it is lightweight relative to its speed class, which helps on larger vehicles or overhead panels. The battery platform caps total runtime per charge, so tasks covering full vehicles may need battery swaps.
What buyers say
Owners reporting across 344 reviews at 4.6 stars tend to highlight the speed and versatility for automotive detailing use. The combination of high RPM and light body weight is frequently noted as a positive. Criticisms focus on battery life management during extended sessions rather than tool build quality or performance consistency.
