There are some unique features that Vorwerk offer with their uprights in general but versus the SEBO Felix there are some similarities. Variable suction control, swivel neck, brush roll on/off (with previous Vorwerk PN heads such as the EB350 & EB351), the ability to lie flat to clean under low furniture, long manual cord on board, even changing over to hand held design where in the U.S you can buy a shoulder strap for a similar Vorwerk like shaped cleaning function. The dust bag capacities are also similarly low with 3 litres, 3.5 litres and then there's also SEBO's DuoP dry cleaning powder. 

It is true that Vorwerk offer some unique features such as an electric PN Polsterboy small turbo brush and the new auto adjusting sensor PN that automatically adds hard brushes down on hard floors and auto retracts the stiff bristles when carpet comes into contact. I'm pleased that those floor heads and other accessories can also be used on my old VK130. I'm also pleased that Vorwerk have retained their low wattage motors as they have always done. Those additional accessories don't come cheap to buy though. The current UK price for the PN head alone is around £150 to £200 which could buy you a complete vacuum cleaner!

However, between the older VK130 I own and my old Felix, I find I'm in a bit of a conundrum. I have a full tool kit with the old Vorwerk but I seldom use it. It just takes too much time to detach and unlock everything just to use the hose and associated tools alone. At least there is a hose on the Felix that I can use, even if it might be short length. I have managed to push my SEBO extension hose onto the mouth of the Vorwerk VK130 when going hand held - far more flexible and longer than the non-electric Vorwerk hose and SEBO's standard cleaning tools aren't so large or as cumbersome.

A few days ago I also treated my carpets with the Kobosan dry powder treatment. My Vorwerk tool kit also includes brush cartridges for that purpose alone. Despite the snow like feel of the powder, there was far more clean up involved than the SEBO Felix after the powder had been rolled into the carpet. Granted my Vorwerk is old but in use, the PN was impossible to keep to a straight line with those dry powder brush bars fitted. At least with the ET-1 on the Felix, the standard brush roll doesn't have to be changed over and the far better control can be had guiding the Felix through the dry powder cleaning stages.

Kobosan powder does seem to work; but I'm impatient sometimes and find rubbing some of the powder manually into the carpet by hand takes a stain out as opposed to trying to keep control of an upright that feels like a hover lawnmower.

What the Felix does offer is a trade off; a far heavier vacuum cleaner by its design, far more substantial build quality, slightly more motor noise, but still low energy rated, better value dust bags, hose on board with cleaning tools, manual height adjustment and simpler filtration. The Vorwerk VK200 is far more high end, not just judged by the price. 

Currently in the UK you could buy yourself three or four SEBO Felix uprights for the price of one Vorwerk VK200 with its PN head.
