Claim 9:
10. A method for removing debris in a wellbore, comprising:
running a downhole tool on a downhole conveyance into the wellbore formed from a terranean surface to a subterranean formation, the downhole tool comprising:
a top sub-assembly connected to the downhole conveyance,
a housing coupled at an uphole end to the top sub-assembly, the housing defining an interior volume,
a vacuum positioned in the interior volume,
a debris chamber fluidly coupled to the vacuum and positioned in the interior volume, and
a nozzle coupled at a downhole end of the housing, the nozzle comprising one or more openings;

positioning the downhole tool at a particular depth in the wellbore above a wellbore component mounted in the wellbore;
determining that the downhole tool is at the particular depth in the wellbore, the determining comprising:
determining, with a controller of the downhole tool, that the downhole tool is at the particular depth, or
determining, with a downhole conveyance unit, that the downhole tool is at the particular depth;

activating the vacuum to generate a fluid suction, the activating comprising automatically activating the vacuum by the controller when the downhole tool is at the particular depth;
determining that the automatic activation of the vacuum failed;
based on the determination, activating the vacuum by the downhole conveyance unit when the downhole tool is at the particular depth; and
circulating wellbore debris, with the fluid suction, through the vacuum and into the debris chamber.
