What do Dyson owners wish they'd known before buying?
They wish they'd known the battery and filters are the real cost.
The machine is great, but replacements add up, and the battery fades faster than you'd expect. It comes down to how often you'll actually use it.

What's your main use?
Why?
Batteries fade Cordless vacuums lose runtime noticeably after a couple years, and replacement batteries aren't cheap.
Filters add up Purifier and vacuum filters need replacing every few months, and the genuine ones cost more than you'd think.
Attachments are pricey Hair tool attachments and accessories are individually expensive, so the full set is a big upfront commitment.
Specific model reliability varies, and newer generations may have improved battery life.
If your situation is different
What's your main use: Hair tools. Hair tools are worth it if you style often. The Airwrap and Supersonic shine for frequent styling, but the attachments and filters are pricey to replace.
What's your main use: Vacuums. Vacuums are great for quick cleans, not deep ones. Cordless models are handy but the battery fades, and you'll want a corded one for big jobs.
What's your main use: Fans/purifiers. Fans and purifiers are quiet but pricey to run. Filters need regular replacing, and the cost adds up over a few years.

What's the biggest Dyson mistake?
The biggest mistake is buying a Dyson for the brand without checking the running costs. People see the upfront price and ignore that filters and batteries will cost hundreds over the machine's life. Instead, add up the replacement costs for five years before you buy, and compare that to a cheaper model with cheaper parts.
How do you decide if a Dyson is worth it?
- Write down how many times a week you'll actually use it.
- Add up the cost of filters and a battery replacement over five years.
- Compare that total to a cheaper alternative with the same features.
- If the Dyson total is more than double, skip it and buy the cheaper one.
