Quick Repair - Hoover Whirlwind WR71

Hello my Vacuum Cleaner Chums!

One of my girlfriends friends asked her if I still repaired vacuum cleaners. Of course, the answer was yes, and I found myself coming home tonight via her house and collecting this



A Hoover Whirlwind WR71.

She said she had had it about 4 months, and it wasn't picking up. A quick browse of google confirm it is indeed current and being sold in Tesco for £50. Hoover want a frankly eye watering £120 for it!

So, I had my suspicions as to what it might be, and a quick test when I got home confirmed the relief valve was opening, and there was sod all suction.

So, I had the cyclone off

 I hate little filters like this. Totally ineffective, infact I threw this away and cut up an random better bit of filter to fill it's gap. So much fluff and debris gets through these things, and clogs the motor fan up
 I undid the cyclone
 undid the filter, and immediatly my suspicions were confirmed
 I'd be amazed if she even knew it had a filter, let alone that she needs to clean and bang it out with every bin empty!
 A brief whack out/vacuum off had it looking like this
 and a more thorough vacuum and brushing had it as good as it was going to get
 I admired the comical dual purpose tool
 A for Energy, Z for actual cleaning/longetivity!
 I flipped it over to give it a check over. The sealing strips for the baseplate haven't fared too well (although I don't know what type of flooring she has, probably something unsuitable like hard flooring)
 I had the baseplate off, and cut the threads off the very stiff brushroll
 The side sealing felt strips were ok on this side
But filthy on this side!

So, it was now working ok again, and can go back to it's owner!

Top Facts!

Cost - £30 - £50
Filter Cost - £7.50 excluding postage
Filters Washable - Yes according to the instruction manual
Wattage - 750w
Energy Label -
Suitable for hard floors - NO! There is no brush control, so you cannot turn the brush off. The brushes are also VERY stiff, so it grooms well, but could damage lino flooring


My Score - 3/10
It's a cheap cleaner, but it shows! This type of cyclonic machine is always awful, the filter will clog VERY quickly, and it will need constant maintenance. I would be surprised if it lasted 2 years of normal use! Spare parts will be almost impossible to get hold of if anything structural breaks, and Hoover will probably not even acknowledge it exists after the guarantee expires

Thanks for reading! I was a nice, easy way of making £15 though...

A Dyson DC24 complete strip down video

Hello my Vacuum Cleaner chums!

Recently, I filmed myself fully componentising a Dyson DC24, in preparation for a refurb.

I do go on a bit, but explain everything in detail.

If you are of the pictures and text persuasion, then I wrote a guide a few years ago here which does miss some of the detail (I really must write an updated version one day) but covers 98% of the detail.

The DC24 is fairly simple once you get used to it. I break it down as:

Main chassis
Motor/Ball/Yolk unit
Brushroll Housing
Cyclone

The only tricky parts I find is the grey pedal spring, and the chassis to ball wiring, which is very fiddly, and I would suggest you make good notes of the fitment of each wire, either by drawing a pretty picture, or taking photographs along the way.

The DC24 is a very finicky machine, which is unsuitable for large or even medium sized homes. The main issues you will have (not if, WHEN!) will be:

Main motor failure - There is a guide to change the motor (written my myself) here
Brushroll failure, caused by either Motor or PCB failure, or a combination of both! Repair guide here

Other DC24 oddities are:

Small ball cog failure - covered here
Cyclone gasket failure - Not covered in a guide, you just buy a new one from here and fit it
Brushroll rattle - Normally cured by a new brushroll and End Cap

If you have any specific DC24 questions, please do comment below and I will try and help! I've had so many apart and back together now, I know them quite well!

DC39 - Stripdown and Refurb

So, a slight change, my Vacuum Cleaner chums, as I realise I cannot write comprehensive stripdown and refurb threads twice.

So, from now on, I shall be linking you to them!

To start, the DC39. I bought this for £15 from facebook, and sold it for £80. It went very well.

Full story here: http://manchestervacs.co.uk/DysonForum/index.php/topic,2313.0.html

and the after video here: Dyson DC39 - After Refurbishment

I hope you enjoy!

Miele S716 - Stripdown and Refurb

I traded this with a DC04 Constant Max I had, and set about refurbishing it



 The small tools were first






 They were certainly used, but not beyond use.

Hose next

 This style of floor tool is horrible to get apart and then back together again. My S5510 had one that I tried with. So this got left alone, apart from removing the litter pickers for washing


Done, onto the main machine


Lift the tool door
 and lift it off it's plastic hinges
 This spring is what makes it lift up when you release it, it just pulls off each end of the clip
 Next, we need to remove the filter
This machine has an Active Air Filter fitted, which was spotless so I kept it

 Time to remove the bag door now. It is held either side by these black pegs
 The one by the power button lifts out and slides off the locating peg on the bag door
 The side by the cord rewind however does still lift out, but contains the plug and wiring for the electro brush connection.
 With that plug removed, the bag door is seperate from the main machine
 On the top of the bag door is a black cover, which hides the wires
 We now need to remove the hinge bracket
 This is done by rotating the backet until the locating lug lines up with the cut out in the bracket

 Once it is lined up you can remove the end where the wires exit from it's molding on the bag door

 I could not figure out how to remove the wires from the plug, so left them alone
and attached it all from the other end, and removed the hose entry assembly, which revealed a plug
 This is the end that the turbo brush wiring plugs into
 The plug splits apart this end, and the wires can be removed and fed through and out of the machine.
 This is the hose entry assembly. The black vanity ring pops off the top, and the rest of the housing unscrews from behind
 Removing the hose entry gubbins also releases the bag indicator.
 as well as the bag door opening latch.
 There was a pattern bag fitted
 but the Pre Motor filter was not too dirty
The bag holder pulls out of the front of the machine
and the pre filter cage pops off from it's lugs

The control panel is released with a screw
and then lifts off, unplugging itself as it goes

The PCB is removed with 2 screws, and the switch pulls easily out of it's housing

Once the electronics are removed, the pedals and power knob pop off the main unit
The first layer is off
6 screws hold the middle layer on
This reveals the motor and cord rewind
The motor and cord rewind are 'modular', so just lift out
The best way to see the history of a vacuum is to look at the motor fan. This was very clean, and doesn't need washing
On the back of the motor sits the thermal cutout module. Dust this off/clean with contact cleaner to ensure it won't make a false reading 
The motor housing seal lifts out 
As does the bag door assembly 
The cord rewind assembly lifts out, and the cable need's plucking from it's holding places 

This pipe forms part of the release valve assembly, and connects to the main chassis and cord rewind assembly 
The release valve sits here, and slides up and out 
and splits apart easily 
The furniture bumper pulls off the lower chassis 
The 3 wheels pop off their pegs, and the wheels pop out of the housings 
 The wheel holding brackets can unscrew now
All the screws on the machine, right here! Everything was washed, dried and polished, the red plastics buffed to a very good shine with the machine polisher

 I put the motor back in first
Then the cord rewind 
Motor compartment seal 
 Bag compartment seal
Bumper on 
Release valve went back together 
and slotted into place 
 The side parking slot was popped into place under the bumper and screwed down
 Release valve pipe fitted
 And the middle housing fitted
Much shine! 
Turned over now, and the wheel brackets are screwed in 
 The wheel holders fitted
Wheels fitted
Time for the control panel assembly to go back together 
Wiring screwed up 
 and screwed down

 The bag door is wired up and the wiring cover fitted, as well as the hinges
 Bag full indicator and hose inlet fitted and screwed down
 Cover plate fitted

 Fitted!
 Tools back together now

And fitted to the machine 
 Post motor filter fitted
 And the tool compartment lid fitted
 I gave the floor tool a little polish

Comsumables time! 
 Pre motor filter
 Bag holder
 Nice new bag
 Air Freshener




And she is done! It came up lovely. Sadly, once it sold, Parcelforce decided to not deliver it, but loose it. After 3 months of conversation I got all the money back that it sold for, so did not end up out of pocket, but it's a damn shame, as the new owner was looking forward to it.

Hey ho, you win some, you loose some!
