the S by S tests and dirtmeter tests have been used by other DTD vacuum companies besides Kirby.Lets see---TriStar,(I have the transparent lid-dirtmeter for a TriStar)Filter Queen(I have a dirtmeter for a FQ in a training kit I bought from the former FQ dealer)Rainbow(Use the water bin as a dirtmeter)and just about any of the others--the factor is--let the prospect use his old,worn out belted vacuum against the brand new out of the box DTD machine.right off we can only guess which machine will do better---BINGO!!!the prospect buys the new DTD machine.If the belt,rollerbrush, bag,and filters were replaced in the prospects old cleaner-then the results would be different.
Fair Test?

no question. But don't forget, if going against a canister machine, all the suction seals and the hose would need to be replaced as well. The direct-air machine with rug-lifting capability is far more easily and quickly restored to a level of dirt-removing prowess more like brand-new than any clean-air machine, whether one or two motor, canister or upright, but as the belt heats up and stretches, it loses it quickly. One absolutely HUGE factor in the dirt meter test is that the challenger with the dirt meter is used in 5 second bursts, and the belt never gets hot and stretches. Even when the incumbent's belt is changed before the challenge, it is used continuously and heats up, with resultant stretch and loss of RPM. Even a small about of brush wear and loss of RPM off of peak is huge. It would be interesting to pit a NIB Kirby against a new Kirby that had seen 15 demonstrations. Enough curve on the bristles and stretch of the belt would have set in to make a difference, I'll bet

The strange irony here is---most DTD vacuums are canisters.Kirby is the only current DTD vacuum now.And the salesman tries the new vacuum in an area where KNOWS there is dirt.and of course the disgusting-but effective dark pad in the dirtmeter test-vacuuming the prospects bed.while selling TriStars a few years ago--did the matteress test---and besides the white "skin ash" there were DUST MITES-the mass on the test pad was MOVING-did work in selling the vacuum!Yes in TYriStars did have to change brush belts on occasion.Bet same with Kirbys-if it had been in too many demos-the belt would have to be replaced.The roller brushes don't get enough wear here.-but you do have to clean the brush of hair,threads and such.A tipoff to the prospect the machine was used.He will INSIST on a lower price for it!Don't blame him!

At the end of the day it comes down to convincing the customer and most times the customer is convinced. Whether they keep there new expensive vacuum is a different story.
I can only speak for my country , I just looked through our a few of our local on-line classifieds, 35 Kirby sentria's for sale 12 other older kirby models, 14 of the sentrias claim to be hardly used bought with in the past 6 months with slips to prove it.( I checked not the same customers ) This tells me one thing , That customers are easily wowed by the sales ticks but like many of my customers who have traded in one find it to cumber sum to use day to day. I have a commercial twin motor tank vacuum with a PN on it, It will not only out clean the kirby but suck it up too, I tried to make a separator tank for it using a 55g oil drum and it crushed it with its suction. Best yet I could by 4 of them for the price of One Kirby but its impossible to use and inconvenient.
At the end of the day it doesn't matter how well it cleans when it is to much effort to use it, remember some people just don't enjoy vacuuming ( shocker )
One thing is did see aswell, you will battle to find any one selling there Rainbow, Miele, Dyson, Sebo or thermax. There was one of each for sale, all old models
