1. Winner of the Test #1 Best Vacuum not to Clog: KIRBY VACUUM
The Kirby vacuum had almost twice the size of suction piping (see pictures
in test #1). The Dyson tubing at its smallest point measures right at 1 3/8
inches, the Kirby tubing at its smallest point measured 2 1/4 inches nearly
a inch larger.
2. The winner Test #2 The most Airflow and Vacuum Power is: KIRBY
The Kirby had over 3 times the power and airflow as the Dyson when testing
it with the airflow meter.
3. Winner of Test #3 - Most Power full of dirt = KIRBY
Full of dirt on the dirt meter the Dyson pulled a 2.8 and the Kirby pulled a
5.9 with a bag full of dirt. The Kirby did lose power when full of dirt (
pulled a 7 with a empty bag) but was still almost twice as powerful when
full. The Dyson pulled a 2.8 empty and a 2.8 full so Dyson was right it did
not lose any power as it filled with dirt.
4. Winner of Test #4 - Best Cleaner = KIRBY
In our dirt test Kirby dominated. It pulled up almost double the dirt that
the Dyson did. The Dyson pulled up 40% of its dirt in this test and the
Kirby pulled up 75% of its dirt in the same test.
5. Winner of Test #5 - Reliability = KIRBY
The Dyson is made of plastic and the Kirby is made of metal. We don't know
how long Dysons will last on average but we have personally seen a 25 year
average lifespan with a Kirby. We have to pack the Dysons with much more
bubble than Kirbys when shipping to avoid breakage. According to "a leading
consumer products magazine" the Kirby ranked #1 in reliability and with the
least number of repairs needed. They ranked it based upon 134,000 reader
responses and ranked it based upon a point system. The lower the points the
more reliable. The Kirby was #1 with only 4 points while the average vacuum
they tested got a 10.25 So the Kirby was not only #1 but much more reliable
than the average vacuum tested.
6. Winner of Test #6 - Weight & Ease of Vacuuming = Dyson
The Dyson was a little over 5 lbs lighter than the Kirby when we weighed
them on our shipping scales. Ease of vacuum the Kirby was better but with on
board tools and lower carrying weight the Dyson won this contest. When we
tested how long it took to use the tools it took the Dyson 19 seconds and
the Kirby 25 seconds.
7. Winner of Test #7 - Tools and Accessories = KIRBY
The Kirby won this contest because it had about 3 times the tools and
accessories as the Dyson.
8. Winner of Test #8 - Filtration = KIRBY
Test #8 was very close. They actually said they had the same filtration .1
of a micron. However the concern we had with the Dyson is it had 7 different
seals (they were not very tight seals) that air and dirt could possibly
leak out. Kirby had 2 seals but were very tight. When "a leading Consumer
Products Magazine" tested emissions (filtration) they gave each the same
rating.
9. Test # 9 Marketing and Cool Factor = DYSON
The Dyson dominated this test. IMHO Dyson is genius when it comes to
marketing. I personally feel that Dyson did not create the best vacuum but
they created a vacuum that would lead us to believe it was the best vacuum.
Visually it seems to do a very good job and looks very cool.
10. Winner of Test #10 - Suction and Vacuum Seal = KIRBY
The Kirby dominated the Suction test. The Dyson only had 1.5 lbs of pull
before the seal was broken and the Kirby had 12 lbs of pull before the seal
was broken. The air coming into the vacuum on the Dyson appeared to come
from on top of the carpet. Where on the Kirby the air coming to the vacuum
appeared to be coming from under the carpet. Also the Dyson had great
suction on one side of the power nozzle and no suction on the other side (
see picture) while the Kirby had suction all the way across. To see more on
this check out my guide called "Picking the Right Vacuum", by Clicking Here.
