Jugglenaut is bugged and sometimes behavior is counter intuitive....
1) Sometimes it's impossible to move the target even with both beams as it appears to be totally glued to the ground...
There is a workaround - push the target somehow first either by jumping on it with sumo or by pushing it with some other units
The cause here is NOT the weight. As the same target on a different time of day, standing on bit different terrain under different angle, will be pulled in/pushed off perfectly fine.
2) In other cases when you try to pull in com and com is walking away, it actually walks away as if it had turbo reactive legs producing much more traction than jugg beams...
3) There are weird cases where jugg produces insane, unmeasurable acceleration over short distance which leads to almost instantaneous unit explosion. Looks like you just started pulling in but something went wrong, target accelerated too fast and exploded after first minor terrain bump because it was moving at near light speed...
Those cases are rare though, from my experience
4) Jugg vs Jugg fights are bugged. Outcome is extremely hard to predict, seems to be heavy rng driven
I often find my jugg unable to pull in enemy's closer while his is pulling mine at a light speed... No idea why
Overall the mechanic and experience is EXTREMELY funny, and the unit role is totally unique
I would be very sad if this mechanic left the game
However it definitely needs some polishing work to do
