I don’t know whether it’s available in Germany but the Oreck XL is a reliable bagged upright. No fancy tubes or attachments. No adjusting for carpet height or bare floors. Just a simple straightforward light, reliable vacuum.
My folks have had one for years, they have a dog. My sibling got one that had been used daily in a small business for years, works great for their pets. I picked one up at an estate sale, replaced the brush roller and it works like new. We have a long haired cat that leaves tumbleweeds in its wake.
If it weren’t for the work of dedicated scientists I’d have assumed the knife would have just melded its the rest of the general subway ambiance.
