When Shark's warranty expires with a replacement I will add a review. I called 800-798-7398 to request warranty service as per the owner's manual. The Shark app told me that the naturally aspirated motor was no longer working. The Shark customer service rep charged me $28.48 to ship the replacement in 4-6 weeks. I liked the vacuum cleaner while it was working. I've set the scheduler in the app to run at 1pm every day. I have two small dogs and one large dog that lives in the house. This vacuum did an excellent job removing all the hair. Yes, I had to empty the vacuum cleaner every day. I wasn't interested. I no longer swept, vacuumed and swept every day. I hope the warranty claim works. I'll upgrade this rating to four stars if I get a working replacement.
