The Equalizer Raptor has eliminated the need for manual-pumping vacuum cups forever by designing the AirForce Constant Vacuum technology into the Raptor.
Simply power-on the Raptor, touch the vacuum cup to the glass and it will automatically secure itself in seconds. By the time you attach the ratchet to the Raptor, the vacuum cup has already created a completely secure seal to the glass and the Raptor will remain secure throughout the cut.
Under normal environmental and fully charged operating conditions, the Raptor can remove up to 15 windshields before its battery system will need to be recharged.
