I've owned a couple of Bissels (proheat) over the years. Both are sitting in some landfill somewhere. Not that durable, and found replacement parts almost impossible to acquire. The factory won't sell you the parts, they tell you to send it to the nearest Bissel repair center.
By the time they'll get through with you ($$$), you will have probably concluded as I have, just chuck it and buy another.
I then went with the Hoover, still have it. It may not offer as many features, but IMO has proven to be a little bit more robust, and seems a much greater availability of parts should you ever need one down the road.
