I've spoken to a couple of vacuum store owners and they've told me that most of the canister vacuums you find in the big box store companies are not good such as shark and Dyson.
He said the reason everyone believes they're so great is because they spend so much on marketing and advertising
It's possible that they just don't make commissions on those and that's why they've told me this but I've heard it from a few different places
That's his opinion.
I've used multiple vaacums over the years, from canisters, old clunky and new lg stick vaacums, as well as in home Kenmore vaacums systems, I have yet to find something comparable to the basic Shark vaacum you can find at Costco.
I have referred over 10 people to try the Shark vaacum you can find on sale at Costco and they were all amazed. It actually works and does an amazing job. Try it for yourself and come back here to thank me. Lol.
But hands down best one I've tried. Not saying there's none other. But this Shark is just amazing. Does a great job.
Here's the exact one I'm referring to. Even on sale now at $149.99
