LEGO Vacuum MOCs: 10 Clever Builds That Suck—in the Best Way
From brick mess to brick bliss: tiny sweepers, city-scale shop-vacs, and even “Shark Tank” brick vac inspiration
If you build as much as we do, you know the cycle: creative whirlwind → parts everywhere → tiptoe through a minefield of plates, tiles, and 1×1 rounds. Enter the humble vacuum—both as a real cleanup helper (hello, LEGO brick vacuum / LEGO brick vac) and as a surprisingly fun subject for MOCs. This guide dives into LEGO vacuum models of every kind: minifigure-scale uprights for your City, compact desk props, and display pieces with cords, wheels, and working handles. We’ll also touch on “LEGO vacuum sort” setups (vac + sieve) and that buzzworthy LEGO vacuum Shark Tank product you may have seen, plus round things off with a curated list of 10 vacuum-themed MOCs you can build today.
Why build a vacuum at all? Because it instantly tells a story. A janitor pushing an upright through your modular hallway. A technician wheeling a bright shop-vac across a Speed Champions pit lane. A retro 60s cleaner parked in a living-room vignette beside a brick TV. Tiny objects like vacuums, irons, and brooms make city layouts feel lived-in—and they’re a perfect canvas for parts-usage creativity: flex tubes for hoses, minifig handlebars as nozzles, 2×2 radar dishes for canister ends, and macaroni bricks for that rounded body. Even the colorway becomes character—industrial yellow for a Technic garage, sand green for mid-century vibes, classic dark bluish gray for modern realism.
If you’re chasing function, you can add motion without going off the LEGO rails. Hinged handles give satisfying pose-ability; winch drums or pulley wheels can act as cord winders; a 20t gear and rubber band can fake a “brush roll.” Building larger? Try a tiled chassis with casters hidden under rounded skirts so the body glides like a real vacuum sweeper. For hoses, flex-tube + 3.2 mm bars + clip plates are your best friends; for tiny uprights, a 1×1 round with bar becomes an instant pivoting neck.
On the real-world cleanup side, many families use “vac + filter bag/stocking + sieve” rigs to scoop parts safely—what the internet often calls a LEGO vacuum sort. And yes, on TV there’s even a dedicated kids’ brick vacuum from Shark Tank—Pick-Up Bricks—a cordless vac designed to collect toy bricks and separate dust/debris so you keep the parts clean (the company showcases it as a “Shark Tank” product).
Below you’ll find practical tips to design your own, scene ideas to spark a story, and a hand-picked list of 10 vacuum MOCs—from bite-size builds to charming display pieces—each with image, designer, and a link to grab the instructions. Happy (clean) building!
Tips: how to design a great LEGO vacuum (MOC)
-
Pick a scale first.
-
Minifig scale: 3–6 studs long, 1–2 studs wide. Focus on silhouette: nozzle, neck, body, handle.
-
Display scale: 10–20+ studs long so you can include cord winders, removable “bag,” and caster wheels.
-
-
Nail the silhouette in 3 beats: nozzle → neck → body. Slope + cheese for the head, 1×1 round with bar (or droid arm) for the swivel, and a 2×2 or 2×3 rounded core for the body.
-
Hoses that behave. Use flex-tube or ribbed hose with clips at both ends. For micro hoses, chain links (stud-direction) curve nicely.
-
Cord & winder. A string reel or small winch hides inside a 4×4 round shell; 2×2 round tiles suggest cord wheels. A cheese-grater tile makes a perfect “vent” texture.
-
Rolling is believing. Two inverted round tiles underneath act like low-friction “glides.” For uprights, a tiny wheel hub (or rounded plate stack) suggests a brush roll.
-
Color tells era.
-
Retro: sand green, tan, nougat with chrome accents.
-
Industrial: yellow/black with hazard stripes.
-
Modern: DBG + bright highlights (lime, teal).
-
-
Add character. A printed gauge as suction control, a clip-on tool caddy, or a detachable floor head as an accessory pack.
Scene ideas to use your vacuum MOC
-
City janitor crew rolling through a modular hallway after a festival.
-
Pit-lane shop-vac in a Speed Champions garage (oil spill cleanup!).
-
Retro living room vignette—TV console, shag rug, avocado-green vacuum.
-
Mall maintenance with signage and a service closet diorama.
-
“Shark Tank” display: build a kiosk for a kids’ brick vac demo, with trans-clear parts “whirling” under a dome (a nod to Pick-Up Bricks).
-
Sorting station: build a mock “vac + sieve” rig with a couple of round meshes to dramatize your LEGO brick vac workflow.
