I purchased the 3 year plan for my robotic vacuum. It stopped working at about the 1 year point. Went to their site, printed the prepaid label, dropped it off at UPS store near me. The sent an email letting me know they received the vacuum, then another email that they were trying to repair it, then another email about two weeks after I mailed it letting me know that a gift card for the full amount would be issued via email to mail as they could not repair it. Took the gift card credit on amazon and purchased a different vacuum. I bought the insurance again, it is worth it!

No problem at all

I purchased a warranty on my vaccum cleaner and it was not picking up when I ran it like it always had. The head part was squeaking and hard to run. I filed a claim they sent me a label we boxed it up and sent it in. They sent emails letting me know when they got it and it was being worked on, Then we it was done they emailed me also, It runs like a new one I am very pleased and so glad I purchased the warranty. Well worth the price for the value!

IRobot Roomba 3 year warranty

My roomba stopped working as it should. It took two claims to get things taken care of but at the end, I was given a gift card for the original purchase price, which I used to buy a brand new roomba. 😁 so im satisfied and purchased another warranty for the new one.

Great insurance!

It worked wonders for me! I sent back my vacuum after a year of using it because a broken spinning wheel and they repaired it. Then, three weeks before the insurance cover expired, a lightning storm occurred in my area and my vacuum didn’t work anymore, they said they couldn’t fix it and they sent me a full refund. Of course I’ll recommend Asurion insurance!
