Vacuum Cleaners Discussions

Hi All,

I have always wondered, why is it so important to empty Dyson when the dirt reaches the Max line?  If the machine does't have any loss of suction then surely this won't harm it at all.  I have had Dysons since 1999 and most of the time always go over the max line without any problems.

My DC04 which is 7rs old always gets the dirt going over the mark line and I continue to use it until I can be bothered to empty it,  this has not caused any problems with it.

Occasionally I have had the odd long bit of hair go onto the Pre motor filter but this happens even if the machine isn't full.   Had this quite bad on the DC05 cylinder which would have literally chunks of hair on the pre motor filter by the time it came to emptying it.

Because contrary to popular belief, the Dyson DOES lose suction. I am not an expert, nor a physics professor, but I know from owning two different models as well as cleaning two other people's Dysons, after about a year or so, they tend to slack off. With regular filter maintenance, which by the way was performed, my DC21 performed well. However, at about month 16, I noticed the hair pickup and dust pickup from the hardwoods was suffering. I took the dust bin assembly apart to find almost 3/4 of the tiny separator holes in the shroud clogged full of fine dust and animal dander. The dirty, nasty job of cleaning it was putrid. I cleaned it up and put it back together. It definitely worked better afterwards. I also had to do the same to my DC07 Animal and my neighbor's DC07 All Floors. None of these machines showed any matter of fine dust clogging the filter, it was all in the separator. When I started incurring problems with the cann model again this last year, I took it to the repair shop locally who services Dyson and his exact words were.... "Dysons require a tremendous amount of dirty maintenance" and "because fo the manner of plastic used inside of a Dyson, the only way to truly get rid of dog smell inside one is to replace it". I did the sheet of paper test on my neighbor's DC07 before and after cleaning the cyclones and the difference was astounding. I thought it would rip the paper out of my hand, post cleaning. This just goes to show, you have to take care of your vac if you want it to work. There is no vac that says, no maintenance, no service, but there are those that require more than others.

That is an excellent explanation.  It does prove that Dyson loses suction when not properly maintained.  It does not take science to prove many things. Contrary to what I responded to it can be proven with a mechanical tool if suction can be measured.

Hi Venson,

I would not neglect the maintenance of the car because wll, the car has so much more to go wrong, thers engine oil, cam belt, air filter, steerting wheel liquid, coolant etc etc.         It is not possible to compare the two.  With regards to Dyson bin emptying I do not worry, this is the same with regards to cleaning the filter, I don't always clean according to the schedule as the filter in my vacuum cleaner filter doesn't get too clogged, my house isn't very dirty - it would be different if there were smokers in the house, the filter would get coated in fine dust quicker,  only think I have on my filter mainly is the odd fine hair that has escaped the cyclone.

With regards to buying another filter, again I do not see this has neccessary,  the whole 7 years I have had my Dyson it has been fine with the original filter that has been washed at least twice a year.

There was a guy that I used to vacuum clean his house after school in 1998 - 99, he has a DC02 which still works today,  he NEVER changed the filter on this machine, just used to vacuum the dust off the filter with another vacuum cleaner sometimes,  the filter must have become less effective and fine dust seeped into the motor but his machine worked perfectly, the only think is the I had to fix the power cord as it became damaged from pulling out the cord too hard, it broke internally, this was quickly fixed and the machine was back working again.  The only thing I noticed is that the Dyson DC02 would run quite hot, this was normal across the board with early Dyson cylinders.  The Dyson cyclone system causes a natural resistance which you can hear when the cyclone is disconnected and then when you connect it the motor pitch increases.

Hardsell,

I'm a little confused.  lazaruspup DID FOLLOW THE DIRECTIONS.  He cleaned the filters regularly.  He said that the obstruction came from dirt build up in the cyclones. It sounds like Dyson needs to be designed so that the cyclone assembly can go through the dishwasher once a year or so.  It's kind of like the cholesterol in your arteries building up and reducing flow.

Excellent idea.  Same cleaning technique performed by many users for Rainbows' separators.

Hi bucks03,

I feel there is a real comparison and the issue becomes more a matter of whomever' personal comfort zones. In short, if you spend money to buy anything but don't do maintenance regarding the look of it, its potential to provided continued and good service then the item's ability to endure and provide satisfactory results while in use may not be taken as a given.

I have a car and it has needs that do not need tending to all at once or all the time. I love the car but hate having to fiddle with it so O try to sstay on top of things. As well, I cannot afford to have a sudden necessity for the management of a number of maintenance needs all at crop up at one time. Though I find it annoying, as you've correctly stated there are dozens of things to keep tabs on, I try to get things done before they become an absolute must. The same applies for my vacuums. Just because I hit the switch and it turns on does not mean all's well. Thus, I make an effort to keep bags and filters on hand so that I needn't worry about over-filling and also make regular checks in regard to brushrolls, belts, etc. (My standard is to only allow bags to get to three-fourths full.) Having gotten into the habit early on, my manner of maintenances helps lift my day a little by my knowing that I have at least one less thing to worry about. That's a good thing.

Hi Carmine, you hit the nail on the head with this. It all sounds well and good but in real life this is the biggist problems with rainbows and bagless machines in general.

Carmine,
Knock-off-manufacturing amongst others stole Dyson’s concise market phrase “No Loss Of Suction” and use it freely in their marketing.  Can you explain why Red is legal/can advertise such claims and Dyson is not legal/cannot or should not advertise such *claims.

Dyson and his team put in the work, Red’s getting a free ride (again).
