Dyson DC31 Handheld cleaner

In the press today:- http://www.thisislondon.co.uk/standard/article-23711862-details/Dyson+with+more+revs+than+F1+racer/article.doProduct details:- - Motor goes at 106,000rpm 'three times faster than any other motor'
- 200 watt motor
- 65/38 air watts (switchable power??)
- £129.99 GBP RRP, powered brush version £149.99
I think the devil will be in the other details, as we learn them. Presumably it's using the Dyson Digital motor? From the photo, the collection bin looks slightly deeper and has a more prominent release switch. It has improved max suction (DC16 has 36 air watts) so I'm presuming (nay hoping) that it can run in standard mode for more than 5mins and switch to a 'turbo' mode as needed? I have prefectly good DC16, but I could be tempted by something with a longer run time and twice the already impresive suction for car cleaning. |

I suppose you have proof to validate this story. I mean proof that you can show us. If not there is no reason to belive it coming from you.

HS:
Ye of little faith. What part of the story would you like me to prove? Carmine D. You could start with proof of anyone who would claim to be your relative.

Well, HS I have that proof. Tho Dr. Lerner has passed as you can see. The relative is still alive and doing well. I'm sure that relative would like as much to recount the story to you as me once again. Your call.  BTW, AAPT stands for American Association of Physics Teachers. My illustrious science career did not end with HS. In college, my Professor was Dr. Charles Pine, also deceased, and equally as reknown as Dr. Lerner. Believe it or not, before the vacuum business, I had plans to be a scientist, thanks to the likes of Dr.'s Lerner and Pine. Dr. Lerner said and wrote about me: The "world hath need of thee." Little did we both know at the time it would be the vacuum world. Carmine D.

Hello Severus: Looks like DIB by his lack of responses here is conspicuosly MIA and absent. In concert with your reservations about the cyclones on dyson's handheld, the Popular Meachanics test complicates the clean-up scenario further with the "wet" kitty litter. Water is tabu for dyson dirt cyclones. Speeds up the clogging process in the cyclones. Hence dyson's warnings about never ever using water and washing the cyclones. Moral of the story, if you want a handheld that looks innovative but only works for 5 minutes on limited clean up jobs, and you have $150-$200 to flush down the toilet, DC16 id the one. If you are looking to buy a real hand held cordless with a 30 year history of product performance and only $50, Black & Decker is the one. Carmine D.
HI CARMNE
$200 for a cordless 5 min hand vac.....thats the price of a brand new oreck upr that will last many years to come....oustanding reliability. 1-2 min use per charge hr for $200..seriously? you have time to clean up one spilled ashtray..then its dormant for another 5 hrs..not practical nor is it money well spent .....reguardless of what it can do 'its not going to do it for more than 5 min . its place is on the shelf of a collector.... it will remain in a cordless/class all its own.....winner....the best $200 5 min hand vac ...category. or wait till this time next year and get them at big lots 2 or 3 for the cost of one now ...thats 10-15min combined use and this way you can have time to properly clean up the whole mess....not half now half later. turtle1

Talking about science DIB, one of my favorite topics. Have you ever heard of the High School course called INtegrated Science? 2 years. It combines the disciplines of physics and chemistry together into one study. The instructor who invented the course and taught is Dr. Morris Lerner [now deceased but the course goes on and advanced into some of the most prestigious universities in the USA.] Twenty five years after I had his course, he met a relative of mine with the same last name as me. He asked if there was a relation to me. The relative said yes and queried how would you remember Carmine's name after 25 years? Dr. Lerner said: I remember the names of all the students who I gave A's in IS. They were a very small number. Nice thing about the story is that it is 100 percent true [I threw that in for HS who hates half truths]. Carmine D. Oh, I get it now... a frustrated science student, going “postal” on those who know how to get things done. DIB

Hello 'turtle1'
I understand from collectors that 3 or more of an item is considered a 'collection' and the owner a 'collector.' Surely a 5 minute charge, requiring 3-5 hours to achieve, is reason enough not to pull a DC16 out for any clean up job. So anyone with 3 or more dyson DC16's MUST be a collector with a collection.

Wrong again. But a good laugh.
A love and thirst for science that was transferred and imputed to a love and knowledge of vacuum cleaners [and I will add a vacuum business and consulting profession in the industry]. The latter is getting things done. If you don't apply the advancements in science to business and technology, it is worthless. If you haven't read already, and I'd bet you didn't, read the link that Severus posted on the dustbuster. Then compare to James' DC16. After 30 years the dustbuster is still going stron and sold over 100 MILLION units. The DC16 is DOA. Carmine D.

You can also overwhelm the cyclonic separation by taking in too much dirt at once. I suspect that most of the dirt that goes into the pre-motor filters is from start up and/or overwhelming the cyclones with too much dirt at once.
Dyson users have reported dirt and sand getting into the pre-motor filters. This is why. With a much lower powered hand vac and users cycling them on and off, I suspect it will be much worse. Hello Severus: I agree. During start up and shut down bagless cyclones have fine dust/dirt lodging in the openings w/o passing into the dirt bin. Especially if users start right into cleanup after startup. Tho, I have not seen the warnings, it would behoove cyclonic bagless brand makers to advise users to allow a brief run time after start up and before cleanup begins. Conversely the same is true with shut down. Allow a brief run time to get all the dust and dirt through the cyclones before shut down. Carmine D.
