If you just want to clean bare floors, choose the Hoover Linx BH50010, it’s much cheaper than the Hoover Air Cordless. It works great on bare floors and also works on carpet, but don’t expect it to deep clean carpets.
If you need cleaning attachments and longer battery life then you should buy the Hoover Air Cordless BH50140. The Linx does not come with any attachments while the Hoover Air Cordless BH50140 includes cleaning wand, dusting/crevice 2-in-1 tool, hard floor brush roll, and pivoting dusting tool. Besides the accessories, the Hoover Hoover Air Cordless series 3.0 provides a much longer battery life, an average of 50 minutes versus about 15 minutes on Hoover Linx.
