I was wondering if anyone besides myself have ever been able to find online the reason Circuit Boards were added to Vacuum Cleaners.

I mean I have searched using all kinds of wording and find, NOTHING.

I imagine there are members who run Vacuum Repair Shops that may know the real reason, and that this subject has been speculated on, but I would like to know why they were added.

I suspect they may have been designed for safety, but I also suspect they are there to shorten the life of a motor so a new motor would have to be replaced or a new vacuum cleaner would be purchased.

I have had some experience with Vacuum Shops to know there is a need to sell new vacuums, I totally understand that. But to tell a customer their motor is shot when all that needs to be done is the brushes need replacing. I personally have experience with this situation, 2 times. The 3rd. instance was, the was sold a very nice Royal Canister because the owner was told the motor is not available any more. Turns out, I replaced it with a Lamb spare and afterwards found the original needed new brushes. (Silly me for not checking that first).

Your thoughts, comments or truth?

I think the number one reason you see a circuit board in a vacuum is it cuts down on costs and increase reliability over having separate individual components.

Circuit boards and power nozzles off and have an overload on them that keeps the motor from burning out.

Some circuit boards also keep the lifetime belt system from burning if it gets stalled.

Speed controls and soft start motors are most reliably done with circuitry.

I used to be very skeptical of circuitry. But really I've replaced very little circuit boards on quality machines over the years. Hoover Kenmore Panasonic and Miele have used circuit boards for 30+ years

It's the key to planned obsolescence...

I hate circuit boards in appliances and am convinced they're intentionally designed as weak links to keep modern appliances from lasting for decades on end like they used to--and should. It's a cheap and easy way for manufacturers to try and force consumers to regularly replace their appliances--and brainwash them into believing the appliances are only supposed to last a short time. Rapidly discontinuing the circuit boards for older models makes it easy for dealers to say "Sorry, that part is no longer available from the manufacturer, and thus your (otherwise perfectly serviceable) appliance cannot be repaired. But since you're here, let me show you our newest line." Honestly, I have had too many circuit boards fail in modern appliances to believe otherwise.
