RM900 for motor change? It is just because Dyson stuff are expensive. Internally, the electronics are simple only. Some higher end one use expensive coating to protect boards from moisture. The motor is probably not even RM100. They are sourced from China.

My factory made many PCB assemblies fro Dyson before it is sent to a plastic company in Johor for complete assembly. I'm responsible to estimate cost to produce the PCBAs. I think it is not difficult to replace the motor yourself if you can observe the right sequence. I only dismantle bladeless fan long time ago when Dyson first start its product. It took me about 10 minutes to assemble it together.

To be honest I do not own any Dyson product because for me it is too overpriced. Not saying the quality is bad too expensive for practical consumer product for me.

Majority of articles in Internet are telling that the lithium battery life does not really depend on how long it has been used but rather how many time it has been recharge. Most articles said the lifetime is at 500 time recharging, but I think nowadays the number is more than that due to advancement in technology.

I worked in factory. I can know how much it cost to make one. The R&D cost maybe high during development time but then reduced over time because basic circuitry design is the same. However, Dyson has many engineers to pay salary for each different models and groups of product but many share the same basic design. The circuitry is not complex like product from other customers of us. We are also involved in giving feedback to Dyson on maneuverability (DFM) during design stage.

I'm not saying those buy Dyson is stupid or anything but for me it is just not good for price/value for me.

Manufacturing plant cost, Raw Material Cost, Labor Cost, Licensing Cost, etc are not under Dyson costs already because they outsource the PCBA and complete assembly. These are under the contract manufacturer. Logistic, Marketing, etc are generally the same like other manufacturer with similar products. Main cost for Dyson is basically R&D.

I used to work in a US company with staff around 100 person only, producing telecommunication product. The PCBA and other mechanical parts are being outsource. Final assembly and testing is done in company factory. We were making like USD30 mil. I would say huge margin compare to cost because product is not end consumer product but communication industry players. Provide 2 years warranty. Unlike end consumer products, you do not need to come up with new model every year like smartphone

I'd say Dyson has established to put its name as luxury item like Apple. Marketing is good so the consumer are willing to pay to its price.

Yes. For this purpose buy cheap wet dry type

Any vacuum that suctions air into fine bubbles though water as filtering agent instead of fiber? I think this will keep constant suction power?
