Electrolux PN floating feature question

[kloveland]

I’ve wondered for a long time why some L shaped Electrolux power nozzles have fixed rear wheels. I have three in my collection. One goes to a Regency series and the others go to the second or third version of the 2100 series. All my other L shaped nozzles have movable rare wheels. 2100 with PN 5, both LEs, epic 6000, Legacy, Marquis, diamond jubilee . Etc

If you put one of the new generic brushrolls in a PN with fixed wheels. The motor slows down and then gets hot. I have not tried one of my green brushrolls yet. It’ll probably do the same thing.

Was this a cost saving measure by Electrolux? to not include the movable axel? Or an experiment in performance like the green brushrolls?.

Cost saving, most likely...

I can't say for sure what was going though the minds of the engineers at Electrolux but it's a common practice in manufacturing, especially when updating a mature product line, to simplify the design with an eye toward reducing the part count and production cost along with it.

I've wondered why they had those in the past, when I had nearly all the "L" nozzles.

I've never actually seen them move. It seems to take quite a bit of pressure to get them to flex.

Let's face it, they WAY overbuilt their vacs back then.

Nice collection and display.

Hmm

I'd modify it make wheels. You have a few machines and I imagine some wheels. If they did cost cutting to the machine. If you modify the wheels to cost cutting mods.

I agree.

They only did that for a short time. Then Electrolux moved back to the pivoting rear wheel assembly. It was probably also for a deeper clean. I feel the fixed wheels dig into the carpet better. I’m just guessing. We used to have a few long time elux salesmen on here.

 

[lesinutah]

Hmm

We still do they just post very rarely. I wouldn't bother waiting as disagreement or proving someone wrong is usually the reason they post. They probably been in vacuum collector scene and don't like or not similar generation of users. They talk to who they know and that's it.

Loosen the belt

Mine did this and the normal power nozzle motor whine was loud and deep, like it was straining. When I put the brushroll in, I tighten the belt a little, but the cogged belts are designed to have a little slack in them. When I put the slack back in the belt it stopped---go figure

 

[lesinutah]

Motor

The motor got hot. If vacuum is having to drag the wheels it strains the motor. If you loosen the belt it may hear motor up more.
With the wheels dragging has nothing to do with the belt.
I can see your point on carpet types. If you have your wheels in any vehicle drag it's a weight issue.
Idk I say modify it to save money.

I wonder if Aerus still has traveling sales people.

 

[lesinutah]

Yes

I imagine every vacuum cleaner company has traveling salesman. It would probably be corporate nor commercial based . It's likely same title slightly different job description.

[gregvacs28]

Just to clarify Les

i'm talking about residential sales.
Not the wholesale sales from corporate to merchants.

It turns out, after doing a short bit of research, that Aerus does have some traveling sales people but it's not an easy job. Most of the clients are older and naive, the sales people need to be slimey liars, and it's all commision sales. Plus Aerus is priced in the Thousands for their stuff.

As I stated in another post, I doubt these small niche market vacuums have much of a future.

 

[lesinutah]

Yes

I agree on that. TTI will gobble them up and then Kirby and Rexair remain.

What do the wheels dragging have anything to do with the motor getting hot?

 

[lesinutah]

Hmm

Do you think the drag. You can't loosen a vacuum belt there not car belts so no tensioner. They have one fixed position.
If you have a load it drags in the rear. The drag is putting the strain on the motor.
I can see if you change the ratio the belt rotates would help. It's what they do to tow help with drag.
The belt might be on the pulley.
Explain to me how a loose belt helps. There seems to be logic. I guess the added belt tension helps lessen the drag.
I can see that but with motor fixed location spindle in fixed location you should throw a belt or it would come off.
If it works great but the motor is not running at full potential. If you don't run motor and coil for designed specs motors don't last as long.
I'm giving reasons for my logic.
You just say loosen the belt.
If you say jump off a cliff it's great. I'm not jumping until reasoning is provided.
I could spout off just pick up nozzle only drag vacuum head towards you I do it all the time.
Reasoning is human nature.
Reasoning?

Original Topic

The spring-loaded rear wheels were introduced on the Omni-Flo Automatic PN5 during the Silverado Deluxe 1505 production era. Shortly after the Canadian and American Electrolux companies merged in 1985 the Canadian plastic tanks were introduced in the American market—including the Hi-Tech 2100 and the L-E 1623. Both had the grid labels along with the Omni-Flo Automatic models 6B and 7B. The 6B's rear wheels are spring-loaded while the 7B's are fixed; also, the air channels on the bases are slightly different. Other cleaners that were paired with the 6B or 7B were the Special Edition & Regency Series. The CB2000 had the 3-wired 6BC or 7BC 3-wire iterations. Those hoods and labels, too, were identical in each model name.

Possibilities for the differences:

1) The spring-loaded rear wheel models (e.g. 6B, 1692, 1693 1750, 1751) were factory paired with the automatics (e.g. Hi-Tech 2100, Special Edition 2100, Regency Series 2000 2100) or the full-featured Renaissance-style tanks, and the fixed rear wheel models (e.g. 7B, 1722, 1723, 1724, 1725, N106M) were matched with the non-automatics (e.g. L-E 1623, Special Edition 1623, Regency Series 1000 1623) or the mid-featured Epic 6500SR-style tanks.

2) A customer option based on preference

3) A salesperson's selection based on the type of carpeting in the home

4) A regional distribution based on the type of contaminants in an area

Btw, my Epic 8000 has the matching N106M with fixed rear wheels, along with other Epic 8000s I've seen.

power nozzle

The holes in the motor are slotted for tensioning the belt. Im just going by what fixed my power nozzle. I have had them apart a lot for I have about 30 of them. Not sure why wheels dragging would affect the motor since it isnt connected to the wheels. This may or may not be his problem, just worked for me. If you over tighten a belt it causes a load on the bearing of the motor and brushroll. Like over tightening a alternator belt can burn the alternator bearings up. The belts have teeth on these which means they dont have to be tight like one without.
