Shark NV652 versus NV752

There is no difference between Shark NV752 and NV652, according to the Shark Customer Service.
However, users say that the included True Pet tool on NV752 has been redesigned, it is smaller and its suction is weaker.

As far as I know, the Euro-Pro recalled certain Shark Rotator Powered Lift Away vacuum cleaners including model NV660, NV650W, NV651 and NV652 on April 22, 2015. This voluntary recall was made because there is potential risk of electric shock caused by the wand.
“The potentially affected vacuum cleaners have a part in the wand that can break, possibly leading to a risk of electric shock under certain circumstances.”

Well, I think they replace the wand, then rebrand the NV650 series, give it a new name – NV750 series. But the vacuum body is still the same.
