Dyson CameraJet

The 68-comment corpus is noisier than it looks: the top-voted HackerNews threads revolve largely around Dyson vacuums — glowing V15 reports ('it filled up almost instantly with stuff my personal vacuum left in the carpet') alongside sharp reliability complaints (a V8 owner reports persistent smells filter changes don't fix; two users call the vacuum trigger a 'deliberate defect' that fails just past warranty, one repaired his with an AliExpress metal trigger). That matters as brand-perception context: admiration for Dyson engineering coexists with distrust of Dyson hardware longevity. On the CameraJet itself, user signals are thin but pointed. Genuine interest exists: 'Absolutely crazy concept. But looks like they actually threw something decent together… the bulk of problems people face with teeth come from poor flossing, this makes it effortless to avoid that.' A long-time water-flosser user flags capacity: CameraJet's tank 'seems to be a tenth vs the 200ml the Panasonic packs,' questioning whether it covers a full 2-minute clean. Another warns water-flosser reservoirs can grow biofilm and 'actively distribute bacteria to my gums' without strict maintenance. Evidence-minded users cite meta-analyses finding 'basically no difference' between electric and manual brushing, arguing the 2-minute timer matters more than mechanism, and scrutinize Dyson's plaque-removal claim as possibly a Dyson-funded or internal lab comparison rather than independent. Privacy jokes recur on ProductHunt: 'Creepy. I might buy it' and 'now you have a camera in your bathroom.' The ProductHunt description (reads as maker copy) details the mechanism: camera watches for gaps between teeth, fires a conical jet of mouthrinse into them, tank works with the handle sideways, dock refills in ~3 seconds, camera streams to MyDyson. Critically, no comment in this sample reports actually owning or using a CameraJet.
