I'll be adding specs to this entry as they become available.  I recently measured the current of my CMM1000 and am looking for a chance to measure the motor RPM as well.  Opportunities to measure specs of the other models will be rather rare, unfortunately.


Battery-operated models

CMM1000
Voltage: 24V, DC
Current: 12A
RPM: ?
Cutting width: 19"

CMM1200
Voltage: 24V, DC
Current: ?
RPM: ?
Weight: 76 lbs
Cutting width: 19"

CM1836
Voltage: 36V, DC
Current: ?
RPM: ?
Weight: 62 lbs
Cutting width: 18"

CM1936 
Voltage: 36V, DC
Current: ?
RPM: ?
Weight: 72 lbs
Cutting width: 19"


120Vac Plug-in models


These all have a Black and Decker 12A motor, according to the product info at Black and Decker.  I suspect there is a step-down transformer involved, otherwise these would consume much more power than the 12V battery-operated CMM1000.  As such, the wall-outlet-current is unknown until I can find a model and measure it.

MM575
Motor current: 12A
Wall outlet current: ?
Weight: 41 lbs
Cutting width: 18"

MM675
Motor current: 12A
Wall outlet current: ?
Weight: 46 lbs
Cutting width: 18"

MM875
Motor current: 12A
Wall outlet current: ?
Weight: 52 lbs
Cutting width: 19"

MM1800
Motor current: 12A
Wall outlet current: ?
Weight: 42 lbs
Cutting width: 18"

I just saw that Black and Decker is coming out with three new electric mower models -- two cordless and one corded.  Amazon has them available for pre-order, with a release date of March 1, 2010.  The new battery powered models are the CM1836 and CM1936, which have 18" and 19" cutting widths, respectively, and use a 36V battery.  Compare this to 19" and 24V for the CMM1000 and CMM1200.  

The new corded model is the MM1800, with an 18" cutting width.

Here is the info from Black and Decker on these new models:
CM1836
CM1936
MM1800

I can see reasons why the CM1936 could be better than the CMM1000 and CMM1200.  For one, the 36V battery is easily removable, so it would be easy to swap in a second battery and cut larger lawns.  Second, the 36V battery would require less current than a 24V battery, for the same amount of power.  The lower current would mean smaller guage wiring is necessary.  The cutting width of 19" is the same as in previous models.

On the other hand, the CM1836 appears to take a step backward, with it's narrower 18" cutting width.  The battery is not easily removable, so in that respect it is no more convenient than the CMM1000 and 1200.

Of course, I am quite attached to my trusty CMM1000 and wouldn't dream of trading it in.  Yet.
