Packed with the Push 'N' Go filter, the debris in your robotic cleaner is easy to remove, and the filter easy to replace. While other robotics have you unscrew the underside, or retrieving an awkward filter, the P825 makes it easy with a clear view port, and a push button ejector. The handle means you won't have to get your hand in a bunch of wet leaves, and it makes replacing the filter easy. Of course the unit still has the same power you would expect from Polaris, both in suction, and drive. The tank treads, combined with a single front brush, means the P825 can more than handle steps, coves, seats, and tiles. This feature rich robot also comes with a free caddy and attached power supply unit, and a generous manufacturer's warranty!
