Checkrate/Likes I spent my afternoon with a friend going to a couple resale shops in town. We ended up at this place called Tom's Treasure Chest and he has a pretty large warehouse in back and that's where I found my latest (old) toy. A Hoover Concept One. Powerdrive model. It was covered in some filth, tested it and it runs fine. Brushroll belt was broken, and the Powerdrive belt was stretched and cracked. Fortunately I had time to run to the vacuum shop and get some new belts for this sucker. I cleaned it all up and it really does look brand spanking new now. I think it was very lightly used in it's past. The brushroll didn't have anything more then some carpet strands stuck in it. The brushroll bearings need some maintenance though. Even the power cord is sparkling white with no dirt on it. Could anyone tell me how old this thing is? I assume it's somewhere in the serial number.

Checkrate/Likes Looks like it's in awesome shape! I love the green. What year was this? I see the shag setting, so I'm assuming maybe 70's? The power drive looks virtually the same.

Checkrate/Likes Haha, I have no clue as to it's age. I think the Concept One was introduced in 1979(???) My suspection is this could be an earlier model, judging from the little design emblem in the center, and maybe the fact that it has a shag setting??? Hopefully someone that knows these machines can step in and tell me.

Checkrate/Likes 1 That's really a beautiful model.. I think it's from around 1980.. maybe 82. One of my favorite color combinations... And it does appear to have been used very little! Congrats! Because that cleaner is from pre-1987, one can't tell date of manufacture.

Checkrate/Likes *Thanks Fred* After I took the photo's I disassembled the machine to maybe find a clump of dirt or something that could have been the cause to it smelling "old" when I ran it, but to my surprise everything inside the motor housing was SPOTLESS. I even checked the carbon brushes and they looked brand new. So I wiped it up, greased the bearings, and put it back together. It clearly was very very lightly used. I greased the brushroll bearings too, they were very dry and making a terrible racket. Now everything sounds very smooth, and it's making that very nice growly "solid" sound that Concepts do. and it's not ear splitting either, despite being fairly loud.

Checkrate/Likes *U3105* I have a U3105 in my collection, which I've had since about 1996. I asked how old it was to a Hoover expert on this site, and the reply I got back was 1982. - Karl

Checkrate/Likes I have a Hoover print out sheet on the whole Concept line sent to me by another member (Thanks Alex) and it said the model 3105 ran from 1979-1986 and also had a matching non power drive sister model 4205 running the same time.

Checkrate/Likes *Transmission* Can anyone tell me how the transmission's in these Concept One's are for reliability? Mine seems to have developed this very annoying racket when you make a quick pass, in forward and reverse, even when you push it fast across with the drive release button held down (no assistance). It sounds very similar to grinding gears in a manual transmission car, which obviously would be very bad. But when it's doing that it has no effect to the performance of the Powerdrive. Overall the transmission assists very well, just as eager and jerky to try and rip my arm out as the last Windtunnel S/P I had in my possession. So would anyone happen to know anything about this? Thanks.

Checkrate/Likes good question, I would like to know that as well. A lot of mine have a kind of sreaming noise mostly in the pull back but they still work great.

Checkrate/Likes *@ vintagecanister* your first model is 4203 and ran from 1978-86 and the powerdrive one is 3341-900 and was a K-mart model that ran from 1991-92. This is however what the spred sheet said. I would love to know if there is a way to copy and post the whole thing for us on this site. It's very detailed as to the years and colors on all of the Concepts. Did anyone know there is like 30 models?

Checkrate/Likes Nice to see your list of the Concept models, and perfect timing to post it with my having just gotten one and digging for every bit of info I can get. I guess my vacuum could be anywhere from 25-32 years old huh. The more I play with and test my Concept the more I fall in love with it. I didn't think Concept's cleaned all that great just by watching people's video's of them. So I was quite surprised to see how good this thing is at cleaning when I first ran it. I ran it over some corn meal, and oat meal this evening and it picked it up completely in just one pass, better then a few of my vacuums. The headlight on this machine is very nice and does a great job lighting the cleaning path, even several feet ahead. Only two things driving me absolutely nuts at the moment are: The transmissions annoying grinding noise that makes me wonder if this thing is gonna hold up any longer. and I'm going on a mission tomorrow to find replacement bristles for the brushroll (one's on this one look brand new still, but i really don't want to be stuck with a useless vacuum years down the road cuz of no replacement bristles)

Checkrate/Likes *CONGRATULATIONS =)* I had 2 of the green ones like yours John, one was an 81 the other an 80. One I sold the other one I have no idea where it went. That happend to alot of my vacs as dad dint like "junk" lying around and even though I had my own vacuum room/workshop things still dissapeared when id go away for a weekend =( Brian I love the blue one, but I also like the beige non p/d. I olny came across one beige non drive and I could not get the horrible smell out of it and it was pretty beat up so it got tossed.

Checkrate/Likes *BTW* My Concepts did make noise when the transmissions were at work. My Windtunnel and Pwermax PowerDrive does to, but I don't use the power drive. I don't care for it but sis and mom did when they were my daily drivers. The w/t is at the BF's and his mom likes the power drive also, but she is also older.

Checkrate/Likes *Concept One* At the convention, I won a blue Concept One Powerdrive in a raffle. It was my first experience with a Hoover upright, and I am very impressed. I love everything about it. The cord reel works well. The power drive is almost comical how fast it can go. And it really cleans well. I didn't know it was two speed at first, and I was impressed even on the lower setting! I plan to bring it back to the convention so that someone else might win it and have such a positive experience. Jay

Checkrate/Likes If the transmission is making a grinding noise, that may be the reason it doesn't have a lot of use on it. If the transmission went bad, that could have put it out of commission early on. It happened. I would definitely keep your eyes open for a Concept that could give you a 'donor' transmission. The transmissions were still available from Hoover in 2007, but they were close to $100, if I recall correctly. I kind of doubt they're still available. Again, though, older vac stores may still have one floating around. I also wouldn't really worry about the brush strips. They only wear down after years and years of use... I would be sure that they're still out there somewhere... you'll find a set eventually. Your brushroll/brush strips look almost factory-fresh. ~Fred

Checkrate/Likes *@Philip:* Thank you for that detailed list! I'm sure MANY will appreciate that. I just happened to find a U3105 today here by Chicago as well. However, it's in good shape, but I still think Johnathon's will take the cake! =0)

Checkrate/Likes 1 *Fred* It only makes that noise if I run full speed across the carpet, if I keep it slow it stays quiet. I can't really complain too much though, i got the machine for 5 dollars. and if this transmission craps out completely I'll just do what you said and find a donor machine. I already had the entire machine disassembled and the transmission will be easy to replace if need be. When I make my video of it for YT I will point out and demonstrate the noise it makes, might be normal for all I know (which is kinda what I'm hoping) Getting my first Concept has really sparked a love for this machine, I really do now get what everyone says about it, and so far has proven to be my favorite Hoover. I look forward to eventually picking up some more Concepts

Checkrate/Likes It's kind of hard to hear over the roar of the cleaner. I would say if it only makes that noise when you push it sort of fast and hard, then.. don't push it fast and hard. That's now how those were meant to be used, and the faster a cleaner gets pushed across a carpet, the less effective it becomes at removing the dirt from the carpet. Granted, that cleaner probably shouldn't make that noise at all ... so be on the lookout for a new transmission... In the meantime, it seems like you won't really have much of a problem with regular vacuuming. But otherwise, it sounds good! Nice video!

Checkrate/Likes I took it over to my grandma's house to give it a good workout and see how it holds up vacuuming a whole house full of carpet (we have barely any carpet in our own house) in order to keep it from making that noise I had to pace myself fairly slow, if I let the vacuum take off it starts making that irritating noise. So I'll just wait and see. I do love the strong solid feel of this machine, especially the way it sounds, powerful growly, like I'd think of a Hoover would sound (too bad they made them all screechy now)

One thing that's interesting is it does not have a Quadraflex Agitator, the one it has looks similar but only has 2 rows instead of 4. Also, it does not have cord hooks on the side of the handle, it has one at the top near the strain-relief for the cord and the other is at the bottom under the bag. Also interesting that it says "Self-Propelled" instead of "POWER DRIVE". I'd love any info that anyone has about it. Thanks!;)

Checkrate/Likes . Vintagevaclover I think it was one of the last Concept I models produced. I love Concepts and buy them pretty much whenever they turn up. I started vac collecting a few years ago and i have noticed how great vacs like these are fewer and futher between each year. Concerning the Concept I that started the thread, it may just be a wheel making the noise. It's a very old thread so no doubt he worked it out.
