HORRIBLE CUSTOMER SERVICE!
Bought 3 year warranty for new Dyson vacuum for $76. On day 2 the battery for vacuum would not lock into place. In order to have a functioning vacuum as quickly as possible, I purchased a second battery from Amazon. That resolved the problem, proving the battery was the problem, not the vacuum. I filed a claim with Assurion, which included sending photos, receipts, etc. The claim was still "processing" for a week. I got on a chat with Assurion, and for nearly an hour I tried to explain why it was unnecessary for me to return the whole vacuum. I asked for a supervisor, but they advised me to call because no supervisor was available. I called, and after finally getting through the computer system, I got the same run around. Finally a supervisor came on the line to tell me that this was actually an Amazon or a Dyson problem, and that I would need to return the entire vacuum. Also they would not "reimburse" for the battery I purchased. I never wanted reimbursement, I only wanted a functional battery - which is what I paid for. The supervisor told me I could "contact" Amazon. Everyone knows there is no human to contact at Amazon. You can keep the product, or you can return the product. As previously stated, I do not want to return the vacuum. Finally, the supervisor connected my call to Dyson. They refused to help me because I purchased the vacuum through Amazon. After two wasted hours, I ended up just where I suspected I would...without any help at all. I am going to try to "return" the useless Assurion warranty.

Asurion protection - I approve
Asurion was able to keep me informed from the start of the return process to its conclusion. They were very courteous and understanding. They resolved the refund swiftly and I had no trouble at all redeeming.

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!
