This is an incredible deal. Groupon has this Dyson DC40 Animal Upright Vacuum Cleaner, which normally sells for $599, on sale for just $249.99!
I LOVE that it has a self-adjusting cleaner head which makes it easy to go from carpet to hard floors without the need to change the settings. It comes with three tools: mini turbine head (for cleaning pet hair and dirt from tight spaces and upholstery), combination tool (with soft bristles for spot cleaning and dusting), and stair tool (great for the corners of stairs and the vertical edges).
As always, Groupon has free shipping on orders over $19.99!
This vacuum is refurbished, but does include a 6 month warranty with parts and labor guaranteed by Dyson.
