Many of us do the same thing everyday without even thinking of a better way to do it. A good example is when we bought our home we went overboard and of course had no money left over. After being in our home for only a few months our dishwasher broke. Because we had no money we went for the cheapest dishwasher we could find. Now this dishwasher was no better or worse then the one that we had before so I thought we did good. Well exactly two years and one month after getting the dishwasher it broke. It needed a major repair. We then looked into new dishwashers. We looked into a Miele dishwasher since we sell the Miele vacuum cleaners and we know how well they perform. We decided on the Miele dishwasher. In the past, even when I was growing up, we always cleaned the dishes and then put them in the dishwasher because if we did not the dishes would not get clean. (I guess they should have been called dish rinsers, since that is all they really did). Well when we got the new dishwasher I was told it would be able to actually clean the dishes. So I put in dirty dishes and I did not rinse them off. Guess what they came out clean. All these years I had been rinsing off the dishes before putting them in the dishwasher and all I had to do was get a better dishwasher. I now know that and I would never go back to dish rinsing again. Vacuums work the same way. Do you have problems with your vacuum not working? Does your vacuum perform inefficiently or do you have to vacuum sections over and over again for anything to happen? If this the case then a new more expensive vacuum would actually perform and last much longer than you current vacuum cleaner. Imagine a vacuum that when you turn it on it performs for you all the time. So yes a more expensive vacuum would be worth it.
