Sebo vacuum cleaners extreme heat

I think that's the reason as to why they don't have an auto sensor ET-1. As far as I can remember the ET-H has an unusual function whereby the dial at the back click locks into a height adjustment but when actually activated onto carpet, the dial doesn't really make much of a difference. If you look at Roger's video for the Sebo K3 Premium, he shows this off to good effect.

The ET-1 was developed purely for manual height adjustment and for a time for domestic owners who wanted something newer - apparently. I don't think I would like an auto sensing ET-H. The Felix is so much better at cleaning around the home because it takes a far shorter time to get around than the slow and progressive X1. I like both as you know, but most of the time my Felix gets used far more often than the X series. I do like the wand and short hose on the X though.

The best I can determine is that the Sebo belt sensor seems to operate by sensing differential rpm between the output shaft of the motor and the brush roll. The sensor is between the motor and the brush roll and can measure the rpm of each independently. I say this because the owners manual for the Sebo Automatic X1 shows the belt sensor in the electrical diagram as two back to back hall sensors. Hall sensors are the normal means to measure rpm or road speed in automotive and motorcycle applications today, so this is a clever application of this technology. It is also easy to make hall sensors small and the signal processing the pcb has to do is trivial.

If the rpm difference between the motor and the brush is below a set value, meaning the brush is spinning about as fast as the motor output shaft, it tells the vacuum to lower the brush roll, or if it has a manual height adjustment it flashes the belt light telling you to turn adjust the height adjuster to the next lower setting. If brush roll rpm is lower than motor rpm by a set value the sensor interprets this as a belt jam, shutting the vacuum down and showing a solid red light on the belt indicator. That sensor is looking for a set rpm difference indicating just the right amount of drag on the brush.

It would also complicate what is an already great power head with manual height adjustment which works beautifully. You've jogged my memory I remember watching Roger's video with the ET-H on the SEBO K3 Premium. I will take another look so I can see that dial you mention on the ET-H thank you.

I know what you about the Felix it does make for quick and easy cleaning and very agile around objects like furniture. That's what I like about the Felix too. I do miss a hose and wand setup which is why I would like an X series for though hard to reach areas both floor and above. Suppose a cylinder would do for that!

Just out of interest have you ever used sebo_fan your Felix or X series with the Duo-P to brush it into the carpet for dry cleaning?

Regarding DuoP powder, I have tried the SEBO trick of unlocking the hose and using the vacuum to brush roll the powder in. It kind of works but I prefer to use the SEBO daisy wheel brush broom - mine is a Rug Renovator that I ordered from a seller in the U.S many years ago and constantly emailed SEBO about it in the UK to stock it in. They eventually relented - the Rug Renovator or SEBO Daisy Wheel brush is perfect for putting the powder down though either way you'll have to clean off the power when you are finished.

On the Felix the bottom of the hose must be kept in place for the brush roll to keep spinning, otherwise when taken out the brush roll will stop.

On the X series the hose can either be unlocked from the top of the machine leading to the bag OR just taken out of the top of the wand hoister since the X doesn't have brush roll on/off.

Thereafter once the powder has been put in and after half an hour when it is time to brush out the powder, I find the entire brush roller does take up all the powder, but the cavity in which it sits in can get a little clogged up. It doesn't affect normal dry vacuuming performance but over time if you leave the powder clogged up in there, it will gradually build up.

Once the hose is added back in, then the powder naturally can be sucked up.

I really like the Sebo Felix and I find it quieter than the X4 machine. It has a pleasent sound. The X4 is more 'deeper' in sound. Plus I think the X4 looks a bit dated.

I've used the the Felix with the Duo P. I removed the top of the hose and pushed the machine over the top of the powder to brush it into the pile. Left it there for 3 hours to ensure fully dried and vacuumed over. I didn't really notice much difference after 2x applications but the powder did change colour, so I assume it 'soaked' up some dirt in the pile.

X versus Felix

The thing about the X versus the Felix in my experience is that the Felix is not a lightweight vacuum cleaner. It isn't designed to be as light as an Oreck but it was designed to offer something different when it came along. More like a small to medium flat and home vacuum compared to the X.

The X series, as we all know is pretty old but for a company who are still private and independent, SEBO have just allowed the old design to soldier on with only a few basic upgrades. Only buy an X1.1 or X4 is you want longer lasting dust bags and a lighter weight to push around. Whilst the X can cope, they're good if you want progressive slow cleaning around your home - I find the Felix is far quicker and dependent on the carpet height setting I have it on, can be lighter to push.

Rather than pay out massively for an X1.1 or X4, my best opinion however would be to find or seek out a refurbished X1 Automatic - the dark grey and light grey contrasting models are powerful enough, even if suction is a lot stronger from the Felix.

It's still the model of choice given their cheap prices second hand. In time the X1.1 will take over but I suspect even with the newer models coming in for the EU Law, it may take a long time for the original X1 Automatic to slowly disappear. At least if you try an X1 Automatic, you can either keep that for the long haul or sell it on cheaply and then finally buy an updated X rather than going full hog and spending some £150 or so on a new model.
