home depot website canada carries both these models. the newer wd4070 does not use the diffuser/muffler, has a different ball float, and includes wheels, extension wand and utility nozzle that were not included in the wd4050. they are selling for the same price, $100.00. has anyone had a chance to compare these two for noise and suction. i could only find a parts list for the wd4070 on the ridgid website, nothing about changes or improvements.
No announcement yet.
