Cleaning Performance

This cleaner is a match for in-ground swimming pools of up to 40 feet, made of anything: Vinyl, Fiberglass, Pebble, Tile, you name it. And the best part is, if you have a newly dried coat of paint, there will be no scuffing from this unit.
The P825 comes with 2 cleaning mode options, namely, a floor option and a floor-wall-waterline option. During a cleaning cycle, its automatic position calibrator comes into play, thus resulting in a periodic, but momentary 20-second stop. After that, it will resume its work.
To easily climb the pool walls, this robot has a Surface Control System to help adjust how the tracks adhere to the wall for precise, spotless cleaning. There are 4 setting options that you can choose from by pressing the SCS button. The 4 LEDs indicate the level you are at, from roughest to smoothest, and you can only go through them in a cycle:

  • Level 1 – Pebble
  • Level 2 – Concrete
  • Level 3 – Vinyl/Fiberglass
  • Level 4 – Tile

The scrubbing of the pool area is done with the help of front and rear pleated PVC brushes that have wear&tear PVC indicator grooves (when the grooves become smooth they indicate the wear). Even if the brushes don’t seem to be worn evenly, the recommended replacement time is every 2 years. All debris dislodged by the brushes gets suctioned by the patented Cyclonic Vacuum Technology, which doesn’t lose suction even with larger amounts of debris, and is sent into the waste canister.

Ease of Use

For easier handling, the cleaner comes with a control box and its own caddy (no tools for assembly required), which is easy to wheel around when putting the device to work. After plugging in the robot and spreading the cable accordingly – ensuring no kinks or tangles – patiently submerge it in your pool and when it reaches the bottom choose the cleaning mode you wish for it to perform. During its first run around the pool, check on its wall climbing performance and adjust the Surface Control System accordingly. If it doesn’t reach the waterline, level up, and if it goes above it and pulls air, level down.
After a completed cycle, check the filter canister through the transparent lid for the waste collection level. Emptying it is a breeze, thanks to the Push’N’Go locking mechanism, just shake the debris out and hose down the canister. Also, be a good sport and also give the robot some attention, using clean water with just a touch of suds and then rinsing it thoroughly. After cleaning, let it dry in a shady spot, avoiding direct sunlight as it might cause damage.
If at any point you might see a LED flashing on the device, your user manual’s troubleshooting guide might help with avoiding a service call:

  • One flash/second – disconnect and reconnect its cable from the power source
  • Two flashes/second – check tracks for jamming issues and brushes for debris*
  • Three flashes/second – check pump or propelled for dirt or clean the filter*

*Start a new cleaning cycle afterward.

Operating Costs

The P825 is extremely energy efficient, and except for the initial cost, it doesn’t require a large amount from your wallet. Being a 30W device with a $0.41 electricity bill a year means you’re looking at only $0.007 per cleaning cycle, should you choose to use it once every week. And it doesn’t make a noticeable difference even if you use it a few extra times either.
Bottom line is, no matter what pool shape and type you own, for around $1,000 you’ll have a sparkling clean pool for several good years.
