WD 2-18

The cordless vac is great for small messes but it's not great for any level of deep cleaning. I use it daily more like a carpet compatible broom than a vacuum. Notice I said I use it daily, that's where it comes in handy, because it's easy to grab and go. If you have strictly hard floors it would be a good replacement. With carpet, no way will it replace a proper vac, but it might be a nice addition for daily maintenance. As for brands. I had a Dyson v11 and I would NEVER buy it again. It was complete crap and lasted just over a year before it stopped running consistently, and that's after I had to make a new wheel mount for the beater bar because the wheels are held on with like 1mm of plastic. For reference I design and 3d print a lot of things and I would NEVER design a product with the shit support that wheel was held on with. I have had pretty good luck with the Karcher that replaced it but the battery life is.... ok. I tend to find it dead a lot more than I would like when I go to use it. Partly because it doesn't really have dock, you have to plug it in and sometimes it doesn't get plugged in. That's more a me problem, with a full charge it has pretty good battery life, more than enough to do any apartment I have lived in. The Karcher also is pretty easy to fully disassemble for cleaning (although it's kind of a hidden feature that so many parts just unscrew/unclip).
