I only have cleaned one drain a very blocked line from my kitchen. The auger did very well after I broke through the blockage. It handled like a large rooter only having a probe to drag out hair and greese ect. I had to go in and out 6 times due to the large amount of blockage ,but it performed. I ran it out 25 feet then I flushed the line out. Its well worth the money I payed for it.
