This version is comparable in suction power / capability to a V6 series Dyson cordless vacuum. I’ve owned one for years and its excellent suction, performance, and versatility make it my favorite handheld vacuum. But, there are now newer series (the V8, V10, V11 series) which cost even more and offer even more suction power. For that weight class though, you need to look at the Tineco S series.
Where it beats Dyson is the remove-able battery packs so you can get about an hour of run time right out of the package.
