I've used a metal rod through that hole on occasion if the nut didn't want to loosen.  Especially if you have the metal separator rather than the newfangled plastic one I'd think you could safely put a lot of pressure without risking any damage.

There are also far better penetrating agents than WD40 - Kroil is considered excellent and PBlaster is also good.  The latter is more readily available.

Well, if they were clogged, wouldn't I have the problem vacuuming my tile floors, not just with the tools?

Before posting, I did blow out the cyclone assembly as best I could with a leafblower and with the appropriate nozzle from my air compressor. I suppose I could swish it in the bathtub for a half hour, as it's too big by far for my ultrasonic cleaner, but the question in the first paragraph still stands.

Well, if anyone cares: I found an older Kenmore unit, obviously a rebranded Panasonic, on CraigsList (for non-US folks, a popular localized online classified ad site),  It's a model 116.22612201.  It had apparently been offered at $75, and when it didn't fetch any buyers the owner marked it down to $25.  We drove over, checked it out, (and played with the owner's 22 pound Norwegian Forest Cat that looked like a small sheep.)  It's in fine shape, remarkably well-maintained, and a steal at that price.  The Dyson murders it in air flow, but it felt in the same ballpark as my Rainbow so I'm sure it will work out fine.  I appreciate VacManUK's Hoover recommendation - this one just happened to pop up at a good time and attractive price.

Does anyone know the vintage of that model?  I'd guess around 1999-2000.

Still pondering what to do on my Dyson, if anything.  I see that thermal sensor available from a seller on the British eBay, but am just a little apprehensive about the amount of work required to replace it and of course have no assurance that this is the root cause of the problem.

Haven't posted here in ages, but enjoy checking out the forum.

I have a Dyson DC07 which gets most of the use in my home, as it's easier to setup and use than my favorite Rainbow. The DC07 has always had the legendary thermal sensor problem when used with the hose and tools - after three or four minutes it shuts off for several minutes until that sensor decides to reset. I've never had the problem using it as a vacuum in my mostly-tiled home, so I haven't worried about the issue.

This weekend, a friend with no vacuum but new carpets borrowed the DC07. I warned her about the problem when using the hose. She rather angrily called me and said it was cutting out every few minutes on her floors. After she calmed down, we decided that perhaps the issue was that it's more of a workload to turn the brush roller on carpeting, causing the overheating issue that I don't see on my own home with only one carpeted room. Is that a valid hypothesis?

I really should deal with the issue, as it's been a bit of an annoyance. So my question: is replacement of the thermal sensor something a reasonably mechanical person can handle, or is it best left to a professional? Can I even get the part in question? I gather from a little bit of web research that there's quite a bit of disassembly involved, but don't have a feel for its difficulty.

Second question: this lady just lost her job, and funds are limited. She'd like to purchase a vacuum, most likely on the used market. Any advice on what she might consider? About the only requirement is that there be a hose and tools so she can vacuum the furniture; guess that cuts out brands like Simplicity. I'm thinking that even Kenmore seems to get reasonably high respect and might be a reasonable choice.

Hello.  Sporadic poster here.  I use a yellow DC07 as backup to the Rainbow.  Someone in the house must have lifted the whole unit by the curved cyclone handle, as an L-shaped piece of plastic that securely anchors the cyclone assembly to the body of the vac has broken off.  It isn't a show-stopper, as the cyclone sits appropriately on the body and is perfectly useable.

Email to Dyson customer service reveals that they only market the entire cyclone assembly.   This is rather silly, not to mention expensive, as the handle of the cylone trivially unbolts from the bin and cyclone mechanism for removal/replacement.

I see the top handle assembly available on eBay out of Britain in various colors (I assume that's purely cosmetic differentiation) but not here in the States.  In fact, I saw the precise "cyclone catch" I needed but it wasn't obvious how to disassemble the curved top handle in order to replace just that lttle grey piece of plastic.

Does anyone here sell just the cylone top (new or used) that I need?
