The Smart Spider from Picote Solutions is for pipes where the base or other sections are missing. It cleans all types of pipes, including PVC. It navigates 90-degree bends, and when combined with the Maxi Miller drive unit, technicians can clean and descale damaged pipes and install a liner in the remaining host pipe. The cable machine can clean 4- or 6-inch pipes and be rebuilt for either size when necessary. 219/440-1404; www.picotesolutions.com.
