I bought this unit against the advice of a pool store employee, but I am sure he would rather sell me one of the more expensive robotic units.After charging it for 12 hours over night, I took it out in the pool this morning and was pleasantly surprised as I emptied basket after basket of grass clippings. At times it clogged, but on anything less than a pile of grass at the bottom of the pool it worked very well.Much better than busting out all the hoses, and backwashing the filter once you are done - and you can use the fine silt filter to remove and sediment.The only thing I am going to different next time is buy the commercial grade version!
