VacuumDrill Pro Brushless
Brushless motors: more work per charge, fewer wear parts.

Why brushless matters
Brushless motors replace mechanical commutation with electronic control. They run cooler and more efficiently, which on a battery tool converts directly into runtime.
They also remove brushes as a wear item, which matters on a tool with two motor loads — the hammer and the pump.
Where it fits
High-duty-cycle use where runtime per charge and service intervals matter.
See the 20 V 6 Ah lithium-ion platform.

Questions about this
What is the practical benefit of brushless?
Higher efficiency, which on a battery tool means more work per charge, plus cooler running and no brushes as a wear item.
Does it matter more here than on an ordinary drill?
Arguably yes, because the battery is powering two loads — the hammer and the vacuum pump.
