Vacuum Cleaners Discussions

Consumer Reports has tested the DC28, and it has earned a "Very Good" score on the carpet cleaning test. They also noted the pet hair performance, as well as tool airflow performance. However, they made a note of how the DC28 may be difficult to push and pull on carpets....which can be the case only if you don't have the brush dropped low enough; like trying to vacuum deep pile carpets with the "short pile" setting.

As usual for dyson his inventions mean nothing to the vacuum cleaner buying public, no benefits at all to the buyer,just an  excuse to keep the r@d money flowing,

You guys talk about everything that means nothing to the consumer,sounds like research lab mumbo jumbo, when is dyson going to learn that a vacuum cleaner is a device for picking up dirt and filth from carpets and flooring? And that as long as the dirt comes out of the carpet the public really doesnt care how,

How much does this piece of artwork cost ? 3 or 4 thousand?

I see the famous dyson cyclone system cant keep up with an industry standard brush system,Oh no what do we do now,retards

Hi,

To be exact CR scored the DC28 as "very good" for carpet, "very good" re tool airflow, "excellent" re emissions, "very good" re pet hair, "excellent" on bare floors, "good" regarding noise but only "fair" in regard to handling.

Though I will never rush out to bring one home, these are the best scores I have ever seen for any single Dyson model by way of CR.

What I also wonder about is how long all this lasts. I feel it's easy to put a new machine through it paces for a short time but the true assessment can't be established until a couple of years or so down the line. How long will the electronic and pneumatic systems endure and are they easily repairable or replaceable by users?

iMacDaddy,

Thank you for the review, pics and video!

Viewing your movie in slow-mo (@ counter 00:42 - 00:46) it looks like the floating head actually raised up (not pushed down) from the carpeting.  Although this could be do to the brushroll tuffs pushing against the mid/high pile carpeting when the vac is set to a low-pile setting.

Q:  Is the “Airmuscle” pushing (downward) or pulling the nozzle upward when vacuuming your mid/deep pile carpeting?

Thanks,

DIB

Hi DIB,

I view the nozzle lifting up as a result of the brush roller pushing down on the carpet, lifting up the floor nozzle as a result.  I like using the "Deep pile" lowest brush roll setting because I feel it delivers the best results for deep cleaning, even though I should probably be using the medium, and even low pile settings for some of the carpets in my household (actually my parents household until I go to college this fall).  Despite the visible lifting, the Airmuscle piston is actually pulling the nozzle inward, which in effect tightens the nozzles contact with the surface.  At first I was curious to see if the piston was actually working at first, since I could not feel the nozzle being pushed into the floor, so I place the maching on a table with the floor nozzle off the edge as I turned the machine on.  As I had it running, I gently kept the nozzle lifted, and as I went from the Bare floor to the Low, Medium, and Deep pile settings, the piston actually did pull in the floor nozzle with considerable amounts of tension.  So now I know that it does indeed function.  I also tried the same test without the clear bin attached (meaning no airflow carried to the floor nozzle), and the air piston did not work, concluding that it draws the pressure from the main airflow, and not from some internal air compressor like I originally theorized.

I also had a little accidental run-in with a sock today that allowed me to see how the clutch would function during an obstruction, and it is not loud and irate like the clutch in a DC07 or DC14.  I didn't even know I ran over the sock until I had noticed the brushroll stopped rotating.  Then I looked over and saw a bright LED flashing from within the translucent red power button.  After that, I turned off the machine for a few seconds, removed the sock, and then turned it back on, and the brush roll was rotating as normal.  Shortly after that, I ran into some loose thick carpeting that was not propertly tacked down into the floor (think of trying to vacuum a bathroom rug), and once again, the clutch activated, with the light flashing again.  Doing what I did before, I turned off the machine, and turned it back on, with the brush roll running again.  The main observation that I gathered from these little mishaps is that the clutch does not emit any loud clicking/ratcheting noises that can be intensely irritating (for me anyway), like with the old DC07 and DC14.  It just stops the brush as an electric motor would with a shut off function.
