This machine worked well for the first year we owned it. After the first year I noticed that the power brush was not working well and at times it would stop working. I replaced the belt but it was no better. I removed to covering plate over the motor assembly and found that the holding cradle for the motor that runs the powerbrush was warren enough to allow the motor to shift forward and create slack in the drive belt. I created so plastic shims to correct the problem and we are working well again. This cradle should be reinforced to take more strain. If not for this problem, I am happy with this product.
