I have not heard this rumor. I expect that it's likely though. Since vacuums were first invented, engineers have tried, repeatedly and without success, to make a portable vacuum that doesn't clog with dirt, doesn't loge airflow (suction), and cleans with 100% suction always.
It had been done with Central Vacuums since the 1913 cyclonic Spencer Turbine was launched, but that's not a portable vacuum. Rexair tried, the Series A had no water and only cyclonic action aided by a rotating separator. It let too much fine dust through, clogging the exhaust filter. Water was added, the exhaust filter was eliminated, but it still didn't trap all the dirt. Dust triumphantly escaped. When asked about this, then President of Rexair was reported to say "It's clean dirt...it's been through the water". Electrolux would realize they could never have the ideal, so they made their cleaners Automatic. The user could select who 'clogged' they wanted the bag to get, and the machine shut off at that moment. But that's not the ideal. Dyson tried. He really did. His problem is the varying amount of air that goes INTO the machine as someone cleans. Imagine the air flow when using attachments like the crevice tool. Use that crevice tool to pick up fine dust (as people do), and the separation efficiency of ALL the cyclones is reduced dramatically. Cinetic was a good idea, an 'ideal' that doesn't and cannot ever work with 100% efficiency. Not in the average home. Maybe in a testing lab, but not in the home. It seems there is no other way for a vacuum to have 100% efficiency with regards to airflow and dirt separation, other than the design of the 1913 Spencer, which today is the cyclonic Vacuflo. |

The upright model has been consistently and quite heavily discounted here in the U.K. lately. I've seen it at £250 in my local Euronics store which is half price. Maybe a further sign they are being discontinued. |

I was worried about the lack of a pre motor filter on this model. It reminds me of Fantom machines. A simple pre motor filter solves fine dust issues and its easy to wash so why not have one? I guess they just wanted people to get excited about the "No Filter to Wash" Idea. Even the Original Cyclon/G Force claimed to have no filters to wash or replace. Their motors must have suffered much like the Fantom machines.
