The present invention provides a simple debris removal apparatus (200) for use in a wellbore. In one aspect of the invention a modular, interchangeable venturi (210) is provided which can be retrofit into an existing debris bailer having a filter and a debris collection container (225). In another aspect of the invention, a venturi is utilised to create a negative pressure in a wellbore sufficient to actuate a retrieval tool for a downhole device. In yet another aspect of the invention, a combination tool is provided which can evacuate debris in a wellbore, thereby uncovering a downhole device which can then be removed in a single trip. In yet another aspect of the invention, a debris removal apparatus is provided with a method for utilising the apparatus in a wellbore on coiled tubing.
