Which handheld vacuum cleaner is good?

clatronic hs2631 Runs on our boat for years, costs around 25,-, really sucks, you can even use it for work, like vacuuming before painting work for example. It has a very long cable and runs on mains voltage. Therefore very powerful. Still small and very handy. Open, shake out, clean.

We have purchased one from aeg. Model Eco hx6 35tm. Bought via a-z online. Good performance and long runtime.

From AEG... X7 or so. Bought regionally from MediaMarkt to keep them around for us. Two years ago I checked which one has the best price-performance ratio after Dyson presented theirs. Has. Then I bought attachments from Amazon so it also works with the car

dyson v6. do not have upright vacuum cleaners, only the one with a tube and a vacuum mop and a robot, although the latter is actually just standing around at the moment...

there is one from Bosch that takes the interchangeable batteries in 18v. green or blue, Amazon will help you find it. it is supposed to be good. you just have to see if it fits into the battery infrastructure.

here in the new development area, basically everyone only has a dyson v6-10 and a robot...

This battery stuff produces, in my opinion, only hazardous waste. It lasts through the 2-year warranty, then the battery is dead. It is so expensive that you might as well throw everything away and buy new. My corded vacuum cleaner has been running and running for over 10 years and is still built unchanged by clatronic.
