A floor grinder with a vacuum is a specialized tool for surface preparation, efficiently grinding concrete, epoxy, or stone while an integrated or attached vacuum system captures dust, creating a cleaner, safer, and compliant work environment for tasks like leveling floors, removing coatings, or polishing surfaces. These machines range from handheld to large walk-behind models, often featuring powerful motors, adjustable grinding depths, and dust skirts for edge work, making them essential for construction and renovation.
