This thread is old, but people still have pools :) So, I decided to share my experience. If someone is looking for a good pool cleaner, I recommend to read the reviews on the Internet like that one on
https://intexpoolpumps.org/best-vacuum-for-intex-pools. It is very convenient as you can compare several cleaners and find out the answers to the frequently asked questions on one page. Having read it, I chose Pentair Kreepy Krauley cleaner and I haven't regretted my choice. I hope this info will be useful for someone!
