Abstract
A hose puller that includes puller wheels that are motorized and configured to grip, among other things, a high pressure water hose. The hose puller further includes an idler wheel that is positioned to oppose the puller wheels. The idler wheel is spring loaded to help ensure that the hose maintains frictional relation with the puller wheels. Alternatively, the hose puller may have puller wheels shaped to grip a high pressure water hose. The hose puller also includes a camera that is configured to show images that enable the operator to control the hose puller from a remote location.
