Some differences between Shark ZU632, NV752, LA502 and AZ2002:
- Brushroll Design
The NV752 has a traditional brushroll,
the ZU632 has a self-cleaning brushroll,
whereas the LA502 and AZ2002 have one soft roller and one Powerfin roller with self-cleaning feature. - Brushroll On/Off Control
The LA502, AZ2002 and ZU632 do not have a brush off setting, the rollers keep spinning in all floor settings.
While the NV752 is the only one that you can turn off the brushroll when setting to Hard Floor.
So, if you want one with a brush on/off button that will not make you worry about scratching your hard floor, have a look at the NV752. - Lift Away Type
The NV752, AZ2002 and ZU632 feature Powered Lift Away whereas the LA502 features Lift-Away.
The difference between Powered Lift-Away and Lift-Away:
Powered Lift-Away allows you to lift the pod and use the handle/wand with a motorized nozzle/tool whereas the Lift-Away only allows you to use non motorized nozzles/tools when detaching the pod.
Obviously, the Powered Lift-Away models are more versatile. Especially when you want to use the powered nozzle to clean under furniture or use motorized tool to clean upholstered surface. - Power Control Location
The NV752, AZ2002 and ZU632 have the power control and surface selector on the handle for easy reach whereas the LA502 has the control on the top of the pod.
Control on the handle is more convenient when you want to turn on/off the vacuum and switch between surface settings. - Headlights
The LA502, AZ2002 and ZU632 have headlights on the floor nozzle whereas the NV752 is the only one that has lights on both floor nozzle and handle.
Headlight on the handle can help you clean low light spots such as nooks and crannies with handle and tools. - Cord Length
The LA502, NV752 and ZU632 have a 25-foot cord whereas the AZ632 has a longer power cable which is 30-foot in length. - Suction Control Slider
The NV752, AZ2002 and ZU632 do not have a Suction Control Slider to allow you to adjust suction to clean different surfaces.
Whereas the LA502 has the suction control.
If you are one of those who want to adjust the suction little by little, you may want to consider the LA502. - Dust Cup Capacity
The AZ2002 has a dust cup that holds more then the other models.
