The Boss 4111 (An Electrolux in drag)

This little fellow came by way of a cousin of mine, who had upgraded. It looks a nice little thing, it found it's way into the back of my car at a family party a month or so ago

It looks tidy. Only had one tool though

and a horrible re-useable cloth bag, with some tears in it as I later find out

I wondered what to do with it at first, until someone at work asked me if I had anything for a 1 bedroom flat with floorboards throughout and one rug. Perfect!

 So let's have it apart!

 The extension tubes have a stiff rubber bush in the end, which pops out very easily

 The parking bracket unscrews from the pole it sits on

Floortool now, and I do like the design of these. Simple but quite effective

 Cover off

 The pedal unclips from the mechanism

 The elbow unpops from the assembly

 and the 2 rubber squeegee's slide out of their holder

This random cover unclips from inside the floor tool

 the 2 rear wheels pop out easily

 And now onto the machine. The tool cover door unclips from it's 2 locating pegs

 poor lonely crevice tool!

Bag door now, which is held on with 2 more locating lugs

 The hose entry gubbins unscrews, and the 1 rubber seal pulls off

 The release clip for the bag door unclips

 The bag full indicator (which doesnt work very well) is held in with these 2 screws

 and comes apart like so

The horrible cloth bag comes out

 and the bag holder slides out of the lower chassis

 This orange part ensures the bag door cannot be closed without a bag fitted, and pulls out

 Post motor filter

 and the post motor filter

 Switch assembly now, which is a pain to get at, with 4 clips needing to be popped out

 to reveal this

 The speed control board unscrews and unplugs from underneath, and the slider pops out with a gentle prod

The pedals are held down with this bracket

 Once removed the pedals lift off

 The wiring to the speed control is held in place with a little rubber grommit

 The 3 Phillips and 1 security torx screw that hold the top cover down are removed

 and the switch unplugged

 The switch unscrews from above, and this small random plastic peg pops out of the top grille

 Switch out

 Identical to a Dyson switch!

 We can see the main bits now!

The motor lifts out

 and the rear mount lifts off

 The cord rewind mechanism holds the PCB
 Once unscrewed the 2 pink wires can be removed from the cord reel

 The back plate of the cord reel unscrews, and the brake mechanism can be removed. As long as the reel is reeled up, the plug will hold the tension in the mechanism. The contact reel between the cord reel and fixed plate lifts out at this point too

Now comes the hard part. The plug won't actually withdraw from the chassis, you either have to cut it off and fit a new plug, or remove the cord from the reel. If cutting the plug off, leave the back plate and brake mechanism on to stop the cord unreeling itself.

 I chose to remove the cord from the reel. The easiest way to do this is to NOT remove the cover on the spring

Which pings the spring everywhere and takes 2 hours to put right. CUT THE PLUG OFF! However, once you have doinged the spring everywhere, you can remove the 3 screws that hold the 2 parts of the reel together (this is probably possible with the bracket fitted, the reel will un-tension itself alarmingly fast though) and seperate the reel. You will then need to cut the wires from the reel contacts and re-solder them on. Great innit (this is why I said just keep the reel whole and lop the plug off...)

I'll come back to that. The top half of the front carry handle unscrews

 The front wheel unscrews

 and comes apart

 The bag chamber seal lifts out

 The hubcaps come off the rear wheels, but I can't see a way of removing the rear wheels easily, so left them alone.

 I dismantled the bag (didn't know it was torn at this stage), The bag holder unscrews with tiny little nuts and bolts

 But is sewn together in the middle for reasons I can't work out...

Done, she is apart! All the bits were washed, dried and polished, and then re-assembly commenced!
Starting with some soldering, I used a PC I pulled out of a skip as a solder station. IMPORTANT, MAKE SURE THE CABLE IS FED THE CORRECT WAY THROUGH THE CHASSIS PRIOR TO THIS STEP! I nearly got it very wrong...

 Refit a reel contact, solder the correct wire on, tuck the wire into the cord grips to hold it, and repeat on the other contact

 Make sure the cable is routed correctly and close the reel up and do the screws up

 Drop the contact plate into the main housing

 It only fits one way

 Re-fit the brake

 I cleaned the rubber wheel up which makes it grip much better

 Fit the brake and screw it up

 Ensure the guide roller is fitted

 Fit the wiring and PCB to the housing

 The easiest way to re-tension it I found was to manually wind the cord onto the reel, fit the reel, pull a foot or 2 of cord out, wind it manually back on and then check the operation. Fine tune it so the action is nice and sharp

 Once happy, fit the reel properly, and refit the motor

 Then the switch and top housing

 Then the very top housing, pedals, pedal holding bracket, speed control knob and PCB and snap that onto the top assembly

 Front wheel refitted

 Rear wheel hubcaps fitted

 Front handle cover fitted

 Bag door safety latch fitted with its spring

The filters washed up well and were refitted

 Bag door clip refitted

 Bag full indicator re-assembled and refitted, then the bag door can be fitted to the machine

 The floor tool and extension wands are reassembled

I found some tools in the shed that fit enough for the tool door to close (and their electrolux tools too, from a Lite/Chic

 Massive bonus was finding this pack of paper bags for it in the shed, which was excellent as the cloth bag was ruined, and I hate re-useable cloth bags anyway, messy to empty and they kill performance

 The hose was re-assembled

 Each end is held in place with removable clip rings

 And it is done!

A tidy little machine, which will go on to give years of service to my work colleague! (hopefully, I sit next to her so if it doesn't I'll know about it!)

Hope you enjoyed reading this!
