Start pause button failed within 8 weeks of purchase. AO replaced the machine, but I think it is due to a design fault so will happen again. For some reason. Hoover have used a touch sensitive button rather than a mechanical one, and placed it on the thick plastic of the body of the machine rather than the thinner plastic of the control panel, where all the other touch sensitive buttons are. This is a standard panel that was used in the previous model, so I guess it was cheaper than redesigning it to incorporate the start/pause control.
