Another new Dyson cylinder - DC32

Another new cyclinder from Dyson. Looks exactly like the DC23T2. Does anyone have any more info on it?

Another question M00seUK since you seem to be in the know:  Are they in the USA other than the dyson web site?  I mentioned I was in Orange County, CA and thought due to the warm year round temps, it might be there.  But...No.  Nothing dyson in fact there.  Even here in the desert of LV, where we've had one of the 10 warmest Novembers in weather history, no new dyson fans anywhere.  So, until its here and available for sale, I can't really evaluate its success among retailers and buyers, as Ross Cameron was able to do.

Strangely they went on sale in the UK today via the Dyson website, despite it being the coldest day of the winter so far! I'm sure they'll still shift a few though...

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.

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.

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.

It's interesting to see other manufacturers using dual cyclone technology as I thought the patent ran out many years ago. I had assumed that they had been frightened to use it for fear of legal action by Dyson on any possible minor technical infringements after what happened to Hoover in the UK.

As for multi-cyclone technology, does anyone know if the patent for that is still valid? If not I wonder how Hoover and Bissell have managed to use them without infringing Dyson's patent?
