Dyson CameraJet electric toothbrush

Water flossers with handheld tanks are already unwieldy. I can't imagine using one with the head vibrating, water coming out of my mouth, and I'm trying to view the inside of my mouth in an app. Replaceable battery though. $20 Sonicare can't do that!

I've had this issue a few times. Took it apart and soaked/scrubbed anything without a pcb or wires coming out of it, and it worked fine after. Eventually the filter on the motor crumbled into dust (not suitable for picking up the dust from sanding paint off indoor walls). I tried to get the right one from Dyson but I ended up just grabbing something that looked like a distant cousin of the right filter off eBay and cut it into the right shape. It stopped working again after a few months, I was going to do the cleansing ceremony again, but then I dropped it and it started working fine again.

Going on 13 years now I think.

Dyson seem to be the champion of turning a cheap effective device that's well understood into the same device but an order of magnitude more expensive. Are people still buying it?

I borrowed a dyson vacuum once from a neighbour. Despite using it to vacuum my apartment after already having used my own vacuum, it filled up almost instantly with stuff my personal vacuum left in the carpet.

My current vacuum is a V15, and I like it a lot. It was expensive (and a gift), but it's very effective, has a lot of attachments to make it easier to clean upholstery/the carpet/a computer/drawers/hardwood/the window frames/whatever, comes with a wall mount that the cable connects to so you can just put it in the mount and it charges. The one issue I had seems to be a relatively well-understood issue with the electronics, which resulted in me having to spend another $100+ on a new housing - the electronics + motor + LCD screen + etc., basically the whole 'vacuum' part of the vacuum. Given how well it's treated my so far, though, I'm not too miffed.

Our last vacuum (which we still have) was a Miele, and while it was also fantastic it was far more of a pain in the ass since it's a plug-in with a bag vs. a cordless canister. The quality is similar, I think the Dyson is a bit better, but I use it exclusively because it's far easier to go get it, vacuum up a spill, and put it back. I know that's more of a comparison between canister and bag vaccums, but the fact that they're around as effective despite the dyson being a canister is I think a point in its favor.

Whether all of their stuff is as good, or only the more expensive stuff, I can't say.

I highly recommend this technical analysis of the advantages of the smart toothbrush, it should help the sceptics.
