Omg I remember the unboxing for this. I can’t believe it was 7 years ago

Brilliant Roger - I think I asked on one of your Christmas videos years ago when you were getting round to fixing this. I just sold my Diversey Ensign SM1 which this video fills me with slight regret. And yes they are sluggish to move up and down 😉

I recently experience a fault with a Sebo X4. After 10mins of use the machine would make a rumbling sound, you could feel the base vibrating. I replaced the speed detection unit (the intermediate belt pulley on the right). I also replaced the brush roll, although not worn the brissels can go soft causing adverse effects on the auto sensing. The PCB has two hall sensors, one monitoring the motor driven pulley and one monitoring the driven pulley to the brush roll. The computer measures the amount of lag between the two pulleys, the more lag the harder the brush drag. The speed detector is spring loaded between the pulleys, so it's a balance between brush drag and the spring tension of the pulley that sets the required height The board on the left is the power supply for the motherboard and height drive motor. Steps it down from 240VAC to 12VDC. Thanks for an interesting video.

The video is really great. I like it so much!

Great video Roger! Amazing that you are able to figure out how to swap electronic components in a cleaner with such a complex system. Indeed, simpler height adjustment systems are less prone to failure. I wonder if the simpler “floating” brush roll in the Miele S7 is less prone to failure.

Ahh, I have one like this, but it's blue & white and branded "Windsor Sensor XP12", the bags are a nightmare to get here in New Zealand, nice to know I should be able to get them under another brand name :)

Awesome Job👌👍👍👍👍👍👍👍👍👍👍👍

Roger i need some advice, my sebo automatic X1 , the motor head caught on my rug, it shut down.i waited switched it on, but unfortunately the motor works but the brush head doesnt move.

I've got two of these, and same fault I think. Got the one that you manually raise, much better.

I love Sebos!

The brush head doesnt rotate.i was wondering if you can give me any advice as to how i can remedy this please

I bought my x4 thinking that it would be good on the laminate flooring, but it just failed. I kept it upstairs for my carpets. I then bought an x4 pet version and although still not good on laminate, it did a good job until I stupidly lifted it up by the handle and it blew up. Now I have a Dyson for the carpet and laminate but the standard x4 still does the stairs with the the extension hose and attachment. Two hoovers to do one house? I know what you're thinking, but I am yet to find a hoover to deal with a stairlift rail and carpet.

Great video!! I can’t stand taking apart vacuums, it’s too difficult for me lol! What vacuum do you regularly use on your thick carpet??

Hi ibaisaic, when are you making the second review of the thomas aqua plus :)

Circuit board looks ok to me Roger.

If you think the ensign with a SEBO head looks strange try one of our grey Nuvac's at work that someone fitted with a red numatic face (and no it certinaly wasn't me in a fit of boredom ;))

I hope you got everything sorted with the instruction manual with your Vorwerk.

The gubbins on the left looks like an inverter that converts AC into DC for the fragile circuits, the servo looks like a DC motor aswell…

First

Couldn't you have just swapped the covers and the head button in 1 minute and be done?

This is actually a kenmore made vacuum

I had one at my old elementary school but the motor was rusted and it was in the janitors office just sitting there waiting for me to take it apart
