Vacuum Cleaners Discussions

The vacuum manufacturers are jumping on the Dyson free-ride big time this year.  I just visited my local Target and it looks like their Bissell's and Hoover's are almost fully converted to single and multi-cyclonic's.  And lookie, lookie... the mighty Electrolux (heavy as a tank upright) has almost caught up with the Fantom vacuum (Dyson dual cyclone technologies), I doubt it filters better than the Fantom's.

Nick,

This is one of the best questions posted here.  Non-Dyson multi-cyclonic’s will ultimately make billions for competing corporations. IMO, Dyson too narrowly defined his cluster (multi) cyclone patent/s, which is claimed to be [stuffed] inside the clear bin and fine dust collector - Bissell’s and TTI’s clusters are not.  They skirted the Dyson patent/s easily by plopping 'their' clusters on top of the clear bin (pulled them out of bin and dust collector) resulting in...  big, easy money to be made.

It's actually inside the assembly that holds the clear bin in place. It's located right above the shroud, lying horizontally, pointing left towards the dust tube. It's a rather stubby, short length tapered cyclonic apparatus.

Interesting.  Thanks.

Thanks DIB. Given the importance of patents, it seems strange that they effectively left a loophole open.

It'll be interesting to see how Dyson will deal with that as, as far as I'm aware, they havn't made any major advances in their cyclone technology since the multi-cyclone so there won't be much to differentiate between them and the much cheaper machines. Fortunately for them they've established themselves well in the marketplace and they have several other novel features which will probably enable them to maintain most of the premium they charge.

You're welcome.  IMO, they should begin obtaining one or two more obvious patents to prevent or make knocking-off more difficult (expensive to build).  Dyson's Core + Root separators paired with his Digital Motor (DC22) is deadly...nothing can touch this filtration (around 4 years of no pre-filter cleaning maintenance).  Only and for some reason he is not advertising this as so.  FYI, the guy who invented the Core + Root is also the fellow who invented the Dyson Ball.  Below is the Dyson multi-cyclone patent drawing.  If you want to read of some future Dyson products, the poster Motorhead put up a short list within this last months worth of posting (search Motorhead).

I'd have thought Bissel, Hoover and co would have taken the opportunity to patent their slight variations of the design themselves if they thought there was a loophole? Can they do that?

I keep an eye on patents filed by Dyson so I know what they're up to but I was about to write something about them on the unofficial Dyson forum so I'll have a look at those posts before I do - thanks.

Have you used the lighter Dyson Ball vacuums?  They will be the next big thing to be knocked-off (attempted).

I think it is Samsung that has more low efficiency (clear bin) w/ conical multi-cyclonic patents than anyone including Dyson.  IMO - Sir James’ team has the most efficient, most consumer friendly, most cost effective in the industry - best separation, low mfg costs, easiest to inspect, easiest to clean, least likely to clog, lightest as possible, lowest handle height as possible (carrying handle on separator unit)…that is the DC14 type (first used on the DC14).  I would of thought Dyson LTD could of obtained some obvious patents to prevent the Hoover/Dirt Devil Synergy-type and the Bissell Healthy Home v.2 and perhaps the Airvolution too (anything but a revolution).

It takes 1 ˝ years on average to have a patent app published.  The Bissell Healthy Home v.1 pat app has been published.

Hello DiB:

I happen to see your comment in parens and thought I'd do some research on this Electrolux Versatility and here it is below.  Tho you say it is as heavy as tank, at  22 pounds 6 ounces it's on par with the latest of your fave brand which weighs in at 21 pounds and most other TOL brand full size uprights.  In fact the user reviews are extremely positive for the Electrolux Versatility.
