iRobot Verro 500 Product Manual - Page 4

 Tips Tip Clean the filter bag regularly. Verro uses the force of the water pumped through its filter bag to maintain traction, particularly on the walls of the pool. If the filter bag is not kept clean, Verro will not clean properly and will not be able to climb the walls of the pool. Tip Change the direction of the handle before each cleaning run to prevent the floating power cord from becoming twisted and to improve coverage of the entire pool. (p. 8) Tip Store Verro in a dry place out of direct sunlight at a temperature between 50 and 104 degrees Fahrenheit. The Power Supply is water resistant, but not waterproof and may be damaged by rain. Important: Failure to properly store Verro will result in loss of warranty. Tip iRobot recommends using the mesh filter bag (available separately at www.irobot.com) when the pool contains a significant quantity of large debris (leaves, etc.), such as when the pool is opened for the season. The fine filter bag is ideal for filtering small debris (algae, sand, etc.) and for regular maintenance. Tip Periodically straighten the floating power cord with the Detangler.  iRobot Verro Owner's Manual
