Dyson has a sale going on. They’re offering the v8 absolute for $349 and the v10 cyclone absolute for $399. Are these worth it even if they’re older models?

Or am I better off just getting a Shark Wandvac for half the price ($180) or the Dyson Omni glide (even though it has much less battery life at $320)?

Hi everyone. I’ve purchased one vacuum in my life and it was the Dyson V7. Now, 6 years later and a dying battery, I need to get something new. Here’s what I’m in between:

The Dyson V15

The Shark Duo Clean

Price is a factor, but if I love something I will pay the extra amount. My hold back on the Shark is that it has a cord and I find myself not wanting to revert to that, however it’s significantly cheaper and well-loved based on reviews.

The Dyson I’m more inclined to because I’ve had one before, plus it’s light and easy to start vacuuming as you’re not restricted by the cord.

Anyone have insight? Is there another vacuum that you recommend that’s better than both of these but under $700?

Thanks in advance.
