543 owner reviews, more than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The DEWALT DCE800B runs on a 20-volt battery platform, which separates it from every corded drywall sander in this category. On a job site with multiple rooms or high ceilings, the absence of a cord reduces setup time and tripping hazards. The trade-off is the battery dependency and the $499.00 tool-only price.
At 8.59 pounds, this sander is heavier than most corded disc sanders but that is expected for a long-reach drywall tool with the added weight of a brushless motor and battery receiver. The 20-amp draw spec reflects a high-current battery design suited for sustained drywall sanding cycles.
With 543 reviews at 4.4 stars, the DCE800B has a meaningful verified owner base for a premium-priced cordless specialty tool. The 100 units sold last month is consistent with a high-cost professional tool that buyers research carefully before purchasing.

Frequently asked questions
Does the DEWALT DCE800B come with a battery?
The listing is tool-only (indicated by the B suffix in the model number). A compatible DEWALT 20-volt MAX battery and charger must be purchased separately.
How does the DCE800B compare to corded drywall sanders at similar prices?
Corded options like the Drywall DWSR-2108 at $179.97 offer more sustained runtime without battery concerns. The DCE800B's $499.00 price premium pays for cordless mobility, which is the primary reason professionals choose it.
