I only buy cordless vacuum's, 1 bc I have a very bad back and they are easier to manage and 2 it's all I need since I don't have carpet, kids or pets in my home! I have been using the Shark Freestyle Navigator for many years and was very happy with it. However, my mom has been using the Linx for years and recently had to replace her battery which was pretty pricey but she felt it was well worth it so I decided to give it a try.... WOW, this little lightweight beauty is so powerful it makes the Shark look wimpy! The design is sleek and it feels as if it propels itself. I absolutely love it and HIGHLY recommend the mighty powerful Linx! The price was incredible as well and evening about it appears brand new. Thank you for making me so happy ☺!
