Great protection plan service
My vacuum stopped holding a full charge after a little over a year, so I submitted a claim to Asurion. They immediately emailed me back with a gift card to cover the cost of replacing the vacuum. I was able to find an even more expensive vacuum that was on sale, so I'm very pleased with Asurion's protection plan.

Refunding/giftcards. Thank you
They were nice enough to replace my vacuum even though the battery was defective. They usually don't cover batteries. So it was a great. But they were nice enough to give me a gift card for the whole amount. Thanks

Great Vacuum for Pet Households
Color: Nordic Blue/Space Grey, Style: Miele Guard L1
Excellent vacuum for houses with pets and carpet. It’s outrageously powerful and is light and easy to maneuver around. The color is a perk too, looks great.

Great vacuum
Color: Nordic Blue/Space Grey, Style: Miele Guard L1
Bought this to replace a Dyson, and I love it! Strong suction and super quiet. I was especially interested in this vacuum because of allergies and wanted better filtration to keep dust down, and this succeeded. I got no dust blowing around and the house doesn’t smell like dog after vacuuming. I did buy the Miele hepa filter since that does not come with this vacuum. Great purchase for allergies - Worth the money!
