So John, Since I believe you have a "Hoovrah" or two in your collection, can you answer me question #1 below? 1) Has anyone ever seen felt washers on the lower bearing And if you wouldn't mind, please post (or refer me to a link) on proper lower bearing greasing pictography. I have watched...

Will, Are you sure you read my entire first post? Andy never told me to oil the bearing, I had no choice but to do so because of the top and bottom felt washers. So far, the oiling hasn't had any detrimental affect. Later on it may, but in order to completely loosen up a partially stuck...

William, Really? 3-4 times the power? I have a Kirby Sentria II that does 137 CFM at the nozzle. So your central vacs do 411-548 CFM at the power nozzle? I wonder how that pushes over medium pile carpet... Oh, and my machine only uses 840 watts (7 Amps) to achieve that nifty 137 CFM. I have...

Edgar, What's the story on your $5 Filter Queen? Was it too much hassle to restore it? Bill

Andy, Thanks for checking into this for me... Bill

Please chime in on this... A few weeks ago, I nabbed a U4007 at a thrift shop and proceeded to restore it as best as possible. I did discover that the upper motor bearing was significantly worn so with the help of Andy R. (vacuumlad1650), I replaced that part. I also discovered that the lower...

To clean the bumpers I use 90% isopropyl alcohol. To help recondition and protect them I use Armor All. Bill

Adin, Well, I did get a mini turbine tool, just not the "tangle free" turbine tool. Here's a pic of the tools that were affixed to the machine. The mini turbine was stuck on the aluminum wand. Bill

I Use a GM8901 Anemometer For my precision measurements and a Baird meter for quick readings. The GM8901 can be purchased on eBay for about $25 USD. BTW, here's another ridiculous pic of the hair clogged filter. Bill

Shae, Can you tell me what models your Mother had? Also, what types of issues did you experience? I now have a 2004 DC14 and a 2008 DC25. Both are in great shape and needed minimal parts. The DC14 works OK, but can't deep clean. The DC25 deep cleans VERY well as my tests now prove. From...

Absolutely, Power usage wise, bag-less machines are the least efficient of the bunch. Most of the airflow gets "used up" in the cyclones. The only reason the DC25 can deep clean so well is that Dyson realized that about 60 CFM was going to be about it for this design. By shrinking the nozzle...

crazykirbydude, Yes, I got all three attachments. They were affixed to the machine, so it was complete. Bill

The first two measurements were easy to get, the last one (CFM at the nozzle) required me to build an airflow box. I think this pic should easily illustrate where and by how much CFM is lost in this machine. I think this is typical performance from a cyclonic bag less cleaner. From the base of...

John, Love the RED one. While this "goldenrod" or whatever the true Hoover color name is, is OK, your red one is very sharp! I looked at getting the F&G bags, but I have a question: Since this machine is used to being "bottom filled", how much airflow is lost by running the air up a paper...

Found the issue... It is indeed just the post motor filter seal. What happens is that over many years, the seal loses its "springy-ness" and no longer creates a seal with the outer motor housing. My seal isn't cracked or damaged in any way, so this is a wear failure. After Googling, I found...

So here's my review after using it for a few hours... 1) Sound quality = A For once, not a high pitched screamer. I could listen to this machine for hours. 2) Maneuverability = B A little hard to push back and forth only due to the tremendous airflow drawing nozzle down to the carpet. 3) Power...

Just scored a curb find of my first Dyson ball vac. After a thorough clean up, the machine emits a very loud howling sound when the post motor filter (in the ball) is installed. I meticulously cleaned and dried both filters, so I'm wondering if this sound is normal. When powering down the...
