My dyson cordless vaccum (v7) was 399$ (CAD) so it was not insanely expensive and I would not go back.

Their tech can probably be imitated at a lower cost, but I won't take chances with the cheaper knockoffs, the tradeoff is not worth it.

Their tech probably can't be imitated at the moment because they've got it patented up the wazoo. Luckily patents have a sane lifetime and once they expire I'd expect many competitors to show up with similar designs at lower price points and possibly better engineering.

Is there a Dyson-equivalent cordless vacuum that goes for less than $200?
