Agitation: rug/carpet deep cleaning performance. Cordless Eufy HomeVac S11 vs Corded Nilfisk GS90 & Sebo ET1 powerhead. Not ideal rug for this test and I should have used sand instead of salt, but you can see the difference.
We enjoyed seeing the contrast between these two machines. As we know the ET1 has plenty agitation to get those particles dancing for us 🤸. We think the best product we've seen used for agitation demonstrations is old fashioned washing powder, cheaper the better. It has some variation in particle sizes, a lower density coupled with a bright white colour which tends to film well. With salt and sand the particles are mostly of a similar size, are more dense and not always so easy to see. Washing powder is however a poor analogue of real dirt with gritty bits - something salt and sand better simulate. Great video.
I am so glad you were able to get a 4k camera! Congrats! It made this video that much more enjoyable! Especially since I just got new glasses so I can actually appreciate the extra high resolution! I liked this test because I think that stick vacuum is very very similar to one I have, and while it does clean very well it has very soft bristles so it doesn't have good agitation as you said, but its really good on hard floors
Nice to hear your thoughts! I have had this OnePlus Nord CE 2 about 2-years now, but I have filmed mainly 1080p 60fps. Now I wanted to try 4K 30fps. It's max what this phone can do.
