Vacuum Cleaners Discussions

It's true, no more clutch.  It uses a brushroll motor.

Hello DIB:

I excerpted this from the dyson link you provided on the DC27:

 "Auto carpet height adjustment:  Conventional cleaner heads have a limited number of height settings. Too low and the cleaner head plunges into the pile making it hard to push. Too high and suction just leaks away."

Based on the height adjustments on dyson's latest DC28, I have to conclude that dyson has mixed emotions and beliefs about the advantages and benefits of height adjustments.  Logically and realistically using a self adjusting dyson upright on a medium to high pile carpet leads to harder and heavier push/pull weight on the usres' arms and wrists.  Adding a adjustment [as in DC28] reduces the adverse affect on the users.

Carmine,

I have not used the DC28 as of yet.  With regards to push/pull weight...  I have never done any push/pull comparisons or measuring on differing carpets.  Logic suggests...  the wheels of a vac sink into the pile and this contributes a heavy/light feel when push/pulling a vacuum.  Logic suggests... measuring how much lift it takes to pull a floating nozzle off differing piles is a good starting point to determine if pile height (in general) makes any real difference to a push/pull feel (strength).  My guess is... the taller the pile, the less the nozzle grips the carpeting (air leaks thru the longer pile)...  and so, Dyson responded by inventing the DC28 nozzle assembly.

Hi DIB,

Sorry to say but your guess is wrong. There is no lift for the so-called floating nozzle. It is just an excuse for not going for the expense of a formal height adjustment as it is meant to "ride" atop both low and high level pile. The best way to achieve that is by use of broad wheels or rollers to better distribute its weight over carpet pile. It's all in the numbers. The example is similar to breaking one stick easily but then attempting to break a bunch of sticks as a group. Wheels that are narrow easily sink into carpet pile. Wide rollers or collection of wheels or simply a wider wheel set fare better on high pile. This is not a new discovery.

The old-fashioned way, the nozzle actually being raised or lifted above the wheel-base to accommodate height is the better thing. Floating nozzles call for other actions. My Miele S7 uses lesser suction delivery at the floorhead to ensure easier pushing san a height adjustment. (This is true and can be tested.) The point best proved is that an aggressive brushroll and some but not all a vacuums air power can take you a long way.

Needless to say, I am totally taken aback by your interest in the DC28 because it barely has a swivel to its name.

On deeper carpets, the vacuum's wheels sink lower into the rug pile.  In turn, the self-adjusting floatation nozzle sinks deeper into the carpets.  Result: The brush roll meets with more rug resistance making it more difficult to revolve.  In turn, the vacuum is harder to push and pull on deep carpets.  Result: The heavier/harder is the push pull weight on the users' arms and wrists during vacuum operations.  One likely solution employed by the vacuum industry for many years, and now even dyson on its latest DC28, is a rug height adjustment.  The general design and fuction of most adjustments is to rasie and lower the height of the rug nozzle to compensate for rug thicknesses.  In dyson's case, the rug adjustments raise and lower the brush roll inside the nozzle accordingly to allow easier push and pull on the users for deep carpets.  Either way, the effect of a rug adjustment is to maximize cleaning performance by the vacuum and minimize the efforts of the users to achieve it.

Hi DIB

I can see why Dyson may not have put the DC27 on the main part of the home page as it just an improved DC14, there is no brand new technology on it just improvements over the DC14. I've seen the base model in the shops it slightly less taller than the DC14 and the bin handle is lower and smaller in diameter to the DC14. I can say it has a 1400 watt motor not 1300 as some websites say as i checked the serial number plate on the display model! Although the airwatts are lower to the DC14! Air seals are better around the bin. Same brush bar\roll as the DC14 if not slightly bigger with slightly more turfs of brushes! I'm yet to test this machine to see what it is like.

Dyson's DC27, a Sams' Club exclusive, now has 5 reviews [wow].  Been on the market since October 2008, or 10 months.  It gets just a tad more than 4 stars, typical for dysons.  About 80 percent positive.  $479 for the Total Clean.

Hoover Fusion has been on the market at least 3 years and gets 8 reviews. It fell short of the "tad over the 4th star".  .

Fusion has 5 perfect stars = 67%.  Dyson had 4 perfect stars=80%.

If memory serves me correctly you tauted the Fusion at Sams as being the Dyson killer.  Wow 8 reviews for this slayer!!!!!!!!!!

Other Hoovers get 1 star of no review.  Your criterion shows that these are either pith poor or not selling.  Hard to believe huh?

Right HS:  HOOVER Fusion $100 dyson $500.  Good comparison!  If you insist on irrelevant comparisons try the HOOVER TEMPO for $80 for its stars/reviews.  Almost 1000 with 4.5 stars. 

Here's an excerpt my good dyson friend.  A meaningful review and analysis. I've owned several and still do.

Remember Carmine.  When Fusion came on the market you predicted that it would be the end of Dyson.  WM and Sam's alone would sell so these and Dyson would sink.  3 years later and Both sell Dyson. Did I mention that in 3 years the Fusion gets 8 reviews.  What a seller.  Now the Whisper is trying the same thing as Fusion.  No listing on Sam's for the Whisper.  If you do not want Dyson compared to you cheapos why do you constantly bring them up and then squak about ythe price difference.  In fact you predicted that the $119 Fusion would unseat Dyson.  Since it didn't you blame cost.  LOL.  What next?

The Tempo scores no better than Dyson on Amazon.  In fact Dyson has a fraction better score.  It seems that most Tempo users were wanting a cheap vac and are satisfied for the performance AT THE COST.  Most Tempo owners woukl be happy with any vac in their double wides.

It also looks like Tempo and Dyson scores superior to the Orecks on Amazon.  And to think those Orecks reach $800 or 5 times the cost of Tempo.

They are coming to take you away haha, haha.

The Hoover has lot's of reviews on HSN... 3.4 out of 5 stars

Fusion
