The Bubble Magic washing machine line is an entry point for ice water hash extraction: the 5-gallon model processes up to 225 grams of trim per run, while the 20-gallon handles up to 2 lbs per batch. Both run on a 110V motor with a 15-minute timer set in 3-minute increments and a built-in drain. Choosing between them comes down to batch size and how often you plan to run.
If you process personal harvests a few times per year, the 5-gallon saves counter space and money. If you run multiple strains per season or process for friends, the 20-gallon pays for itself in time saved within a few batches. Below is a breakdown of both sizes, kit options, and how they compare to commercial alternatives.
Which Size Bubble Hash Washing Machine Do I Need?
Batch capacity is the deciding factor. Here is how the two sizes compare across the specs that matter most:
Both machines work the same way. The difference is scale: the 20-gallon processes roughly 4x the material per run, which means fewer total washes to get through a harvest. For context on the full extraction process, see Bubble Hash: The Definitive Guide.
Best Bubble Hash Washing Machine for Personal Use
The 5-gallon Bubble Magic is the right starting point for home growers processing one to four plants per run. At 225 grams of trim per batch, you can work through a typical personal harvest in two to three washes across a single afternoon.
The machine-only option makes sense if you already have a set of bubble hash bags from a previous setup. Otherwise, the starter kit bundles the machine with a matching bag set in one order.
Best Bubble Hash Washing Machine for Larger Batches
The 20-gallon Bubble Magic is the larger machine in the lineup: it processes up to 2 lbs of trim per run, cutting the number of washes in half (or more) compared to the 5-gallon. If you grow more than four plants per cycle or process trim from multiple harvests, this is where the time savings become significant.
The 20-gallon machine takes up more floor space (roughly the size of a large cooler), so plan for a dedicated wash station. A garage, utility room, or outdoor area with a hose bib works well. Drain the machine between runs using the pump and built-in drain hose.
Machine Only vs. Starter Kit: Which Should I Buy?
Both the 5-gallon and 20-gallon machines are available as standalone units or bundled starter kits.
Buy the machine only if you already own a compatible bag set or prefer to choose your own micron sizes.
Buy the starter kit if this is your first extraction setup. The bundled bags are matched to the machine's drum size.
What Should I Look for in a Bubble Hash Washing Machine?
- Batch capacity: Match the machine's gallon rating to your typical harvest size. The 5-gallon handles up to 225g per run, the 20-gallon up to 2 lbs. Undersizing means more washes; oversizing wastes ice and water.
- Agitation method: Both Bubble Magic machines run a timed agitation: a 15-minute timer set in 3-minute increments.
- Drain system: Both sizes include a built-in drain hose that flows the water into your bags, and the 20-gallon adds a pump. No lifting and pouring a heavy bucket of ice water.
- Motor durability: Both machines have a 110 volt motor for use in North America. Both run on standard 110V household power.
- Kit compatibility: If you already own bags, confirm they match the machine's drum diameter. Bubble Magic bags are sized to their specific machines (5-gallon or 20-gallon).
What About Commercial Hash Washing Machines?
The Bubble Magic line covers home and small-batch extraction. If you're processing at commercial scale (tens of pounds per run), the category steps up significantly in price and capability. The Triminator The Maker ($9,925) handles high-volume runs with stainless steel construction, while commercial washing machines from Lowtemp Industries run up to the 75-gallon Osprey, which Lowtemp rates at 21,000 grams of fresh frozen material per batch. Triminator lists The Maker in a 20-gallon Standard and a 65-gallon XL.
For most home extractors and small operations, the Bubble Magic machines offer the best balance of price, capacity, and build quality.

Bubble Magic 20 Gallon or Aether Green V2?
There is a step between the home machines and the commercial ones. The Aether Green Automatic Hash Washer V2 is an 8 gallon washer with one-button Auto Wash, three saved presets and a real-time temperature monitor. It does not wash more material than the 20 gallon Bubble Magic. In practice, it is for the hashmaker who wants each wash to repeat the last: Auto Wash runs the pre-soak, the wash timing and a ramping agitation, and the false bottom and tri-clamp drain valve are 304 stainless steel. Aether Green says experienced hashmakers can finish a full 3-wash cycle plus cleanup in under an hour.
The two machines answer different questions. The Bubble Magic 20 Gallon takes up to 2 lbs of material per run on a 15-minute timer set in 3-minute increments, and it costs far less. The Aether Green V2 lets you set the agitation pattern, speed and time, save them as presets, and watch the wash through a lit viewing window. Pick the Bubble Magic when the limit is how much trim you can get through in a day. Pick the Aether Green when the batch is small and the goal is the same wash every time. The Aether Green Automatic Hash Washer V2 review goes through its modes, settings and specs in full.
The Aether Green also comes as a Combo Set with a portable rinse station that needs no plumbing and an eight bag filter set from 220 to 25 micron, which makes it a complete first setup in one order. Its warranty covers consumer use and excludes commercial-frequency use, so it is a home and small-batch machine like the Bubble Magic line, not a step into production.
How to Get the Best Results from Your Bubble Magic Washing Machine
The machine handles agitation, but yield and quality still depend on preparation:
- Freeze your material first. Frozen trim releases trichomes more cleanly. At minimum, freeze for 24 hours before washing. Fresh-frozen material (frozen immediately after harvest) produces the highest-quality hash.
- Use enough ice. Maintain water temperature at or below 40°F (4°C) throughout the wash. A good ratio is roughly 50% ice to 50% water by volume. Add more ice between runs if the water warms up.
- Don't overload the drum. Stay within the rated load: up to 225 grams in the 5-gallon and up to 2 lbs in the 20-gallon. Overpacking reduces agitation effectiveness and can increase plant contamination in the final product.
- Run multiple washes. The first wash produces the highest-grade hash (mostly full, intact trichome heads). Second and third washes pull smaller trichomes and fragments. Most extractors run 3-4 washes per load, keeping each grade separate.
- Dry thoroughly. Spread wet hash on cardboard or parchment in a thin layer and dry in a cool, dark space for 24-48 hours. Proper drying prevents mold and preserves terpenes.
