ABSTRACT:
An apparatusdelete-start id="DEL-S-00001" date="20070424" ?for use ondelete-end id="DEL-S-00001" ?insert-start id="INS-S-00001" date="20070424" ?comprising a vehicle adapted to move acrossinsert-end id="INS-S-00001" ?a surface and responsive to an operator. A head assemblyinsert-start id="INS-S-00002" date="20070424" ?connected to a support on the vehicleinsert-end id="INS-S-00002" ?is adapted to carry a device for engaging the surface. An actuatorinsert-start id="INS-S-00003" date="20070424" ?on the vehicleinsert-end id="INS-S-00003" ?raises and lowers thedelete-start id="DEL-S-00002" date="20070424" ?head assemblydelete-end id="DEL-S-00002" ?insert-start id="INS-S-00004" date="20070424" ?supportinsert-end id="INS-S-00004" ?relative to the surface.

As a result, a repeatable positiondelete-start id="DEL-S-00011" date="20070424" ?or range of positionsdelete-end id="DEL-S-00011" ?of thedelete-start id="DEL-S-00012" date="20070424" ?brushdelete-end id="DEL-S-00012" ?headinsert-start id="INS-S-00008" date="20070424" ?assemblyinsert-end id="INS-S-00008" ?is obtained, the relative engagement between the head assembly and surface is controlled and the treatment of the surface by the head assembly is controlled. Position control may be used in combination with torque control of motors driving brushes for engaging the surface. Position control may also be used in combination with a pressure control measuring the pressuredelete-start id="DEL-S-00013" date="20070424" ?betweendelete-end id="DEL-S-00013" ?insert-start id="INS-S-00009" date="20070424" ?ofinsert-end id="INS-S-00009" ?thedelete-start id="DEL-S-00014" date="20070424" ?brushdelete-end id="DEL-S-00014" ?headdelete-start id="DEL-S-00015" date="20070424" ?anddelete-end id="DEL-S-00015" ?insert-start id="INS-S-00010" date="20070424" ?assembly oninsert-end id="INS-S-00010" ?the surface.
