Ecosystem

42078-1 Mack Anthem — 42078-1 Mack Anthem is one of those sets the reviewer wishes they got while still in production, as the price has gone up significantly in recent years

6693-1 Refuse Collection Truck — First Technic version of a garbage truck; garbage trucks are not new to LEGO, with the first appearing in 1987

Automated garbage truck LEGO Ideas submission from 2019 — The concept of the side-loader garbage truck and grabbing mechanism looks similar, but it's not the same design. The reviewer suggests this is coincidental rather than copying, as experienced designers would naturally arrive at similar mechanisms for the same task.

Minifigures & Standout Parts

Standout parts (per reviewers)

red and blue one by one tiles
represent refuse/garbage/recycling material that can be picked up and placed in the bin as part of play function
5405 Technic Knob Wheel 45° Offset
New mold, a variation of 32072 with the axle hole rotated 45 degrees, allowing for 2 knob gears to be lined up next to each other with connecting axles in the same orientation, enabling certain functions not possible before
2391 Technic Beam 1 x 7 Thick with Alternating Holes
In White, a new color for this part
New knob gear
Cross axle hole is rotated 45 degrees, which simplifies many mechanisms and is needed to keep the gripper arms in a symmetrical position. Reviewer hopes to see similarly offset versions for other gears used in steering systems.
Axle and pin connector in reddish brown
This is the first time this color has appeared in a Technic set.
Cross-block piece for steering
Relatively new piece that could become common on vehicles of this scale.
