Surface processing equipment (100, 400) comprising one or more sets of rotatable tool holders (110) for processing a concrete surface, the equipment (100, 400) comprising a protective cage structure (120) arranged to enclose the sets of tool holders (110), the equipment (100, 400) being arranged to cooperate with a dust extraction system (130) arranged to draw a particle-laden airflow (A) from an interior of the protective cage structure (120) via at least one aperture (250) formed in the protective cage structure (120), where at least one further aperture (250) is formed in the protective cage structure (120) to allow an amount of air to enter into the interior of the protective cage structure (120).

An orbital sander may include a housing defining a handle portion and a motor housing portion, a motor within the motor housing and including a motor shaft defining a motor axis, an eccentric drive unit coupled to the motor shaft and configured to convert rotation of the motor shaft to an orbit motion around the motor axis, a battery receptacle on the handle portion that is configured to receive a battery pack for providing electrical current to the motor, a backing pad coupled to the eccentric drive unit for orbital motion about the motor axis, and a dust collection assembly including a dust shroud into which an airflow containing dust created during a sanding operation is induced. The motor housing portion and the dust shroud are in fluid communication with each other.
