I can imagine why these things are expensive, as someone who occasionally cleans the local Olympic pool using an underwater vacuum cleaner (just a side gig to get free diving time). Salty or chlorinated water (and public pools usually use heavily chlorinated water) will dissolve almost anything over time - I've seen chlorinated water eat through plastic or neoprene in 2-3 years of use. Account to that mentioned vacuum cleaner is used practically every day, through the whole year, now you have to imagine that these things must be designed for heavy-duty things.
$4100 is peanuts compared to how expensive are (professional) underwater jobs.

This is why in marine environments, special grades of stainless are used. Most commonly SAE 316 alloy (often marked with "A4", vs "A2" for regular stainless). Another approach is the use of sacrificial anodes. Where practical, it helps to rinse equipment with fresh water after use.
- amelius 3y agoYes, and it's not just the chlorinated water, but also the atmosphere in a swimming pool that causes problems. https://www.hse.gov.uk/foi/internalops/sims/cactus/5_02_18.htm https://www.hse.gov.uk/foi/internalops/sims/cactus/5_02_18.h...
