Be careful about the rumors you claim as fact

FYI -Bosch has no involvement in the VW scandal. They do NOT provide the software to VW. VW produces their own software in house. Bosch provides the hardware only. Bosch has made this clear in public statements on the VW scandal. No authorities have accused Bosch of any involvement in the VW Diesel emissions issues.

In regards to vacuum cleaners, there is no cheat code by Bosch contrary to your assertion. What the Bosch vacuum cleaner does is increase the power as needed. The energy tests currently show typical power not that of a vacuum with a full bag or a restriction that can increase power consumption. These power consumption tests like auto mpg tests do not always provide sufficient data for consumers.

In a petrol powered vehicle the mpg can vary as much as 30% just by how a person drives the vehicle. Authorities have tried to hone in the mpg tests to be more representative but it's impossible to account for a 30% variation and have any meaningful data. The goal is to find a realistic reference point to compare products but there is always a disclaimer that your results might and probably will vary. As an example I never had a problem equaling the EPA mpg ratings on various cars even though I tend to drive in a spirited manner. Other people get less than the EPA estimates and some get better than the EPA estimates.

That is exactly how it's suppose to be and why consumers should educate themselves on what a test does and does not do and how to use the information provided. In the vacuum tests they might want to have a normal operation test and a max power consumption test for when the bag is full or the plumbing obstructed. The question is how many people continue to run a vacuum in this mode vs. normal operation. Is there really a need to have a max power consumption mode test? When it comes to test data, people will misuse it to their benefit whenever possible. Understanding what the data means is often lost on journalists and the general public. That's how people reach completely false conclusions often by design.
