Well, Indians have learned this technology from abroad--mostly Middle East, thats where many Indians work. Of course, now Indian companies make those sprayer bidets.
Squat toils + bidet attachment is better than squat toilet and a jug for water. No dispute about that. Sit down toilet + hand held bidet attachment is worse than sit down toilet + bidet inside in the toilet without using hand. My answer was about sit down toilet with hand held bidet attachments; how Indians discovered these hand held bidet attachments.
