Patent number: 9587410Abstract: A pool cleaner debris bag is provided having an open end adapted to receive debris from the pool and a closable end defining at least one discharge passage for the bag. The pool cleaner further comprises a securing apparatus disposed along at least a portion of the closable end. For example, the securing apparatus can have at least two separable members selectively movable between an unsecured position to permit opening of the discharge passage, and a secured position having at least a portion of the first end is disposed between the at least two separable members to permit closing of the discharge passage. In addition or alternatively, the debris bag can comprise a seam disposed at a location spaced apart from the open end for defining at least one discharge passage for the bag. In addition or alternatively, the securing apparatus can comprise a clasp.Type: GrantFiled: July 28, 2009Date of Patent: March 7, 2017Assignee: Pentair Water Pool and Spa, Inc.Inventor: Suresh Cherulassery Gopalan

Patent number: 7721370Abstract: An adjustable hose clip is provided for use with a pool cleaner debris bag, including a first member having a retaining arm and a second member having a retaining arm. The hose clip also includes means for connecting the hose clip to a pool cleaner debris bag and resilient means for resiliently biasing the retaining arms towards each other such that at least a portion of a pool hose can be retained between the retaining arms. In one example, the resilient means is adapted to automatically adjust the distance between the retaining arms to accommodate various pool hoses having various diameters within the range of a minimum diameter to a maximum diameter at least 50% larger than the minimum diameter. In addition or alternatively, an arrangement for cleaning a swimming pool can include an automatic pool cleaner, a debris bag, a hose and an adjustable hose clip.Type: GrantFiled: June 19, 2006Date of Patent: May 25, 2010Assignee: Pentair Water Pool and Spa, Inc.Inventor: Suresh Cherulassery Gopalan
