So I got a dyson when I bought my house...but I also got a shop vac and them shop vac will work way better...but also blow stuff around too.
Then afterwards use the dyson to finish after the shop vac. Nothing beats a shop vac, nothing.
Isn't Shark made by Dyson or something like that?
If allergy or pollen is a problem then get an air purifier, but remember to change filter often.
