If you've already decided on Reencle's Gravity line, the Prime vs. Gravity question is behind you — now it's Gravity ($699) vs. Gravity Pro ($749). The short answer: both run the identical living-microbial composting process and produce the same real, soil-ready compost. The $50 difference buys you a larger processing capacity and an upgraded finish, which matters if your household generates more food waste per day than a typical 1–3 person kitchen. Below is exactly what changes between the two, so you're not guessing.
The Core Process Is Identical
This is the most important thing to understand before comparing specs: Gravity and Gravity Pro are not different composting technologies. Both use the same maintained microbial culture, the same heated and aerated chamber design, and the same odor-control approach. Neither model "composts better" than the other — the biology is the same. What changes is how much the machine can handle and how it's finished.
Side-by-Side Comparison
| Dimension | Gravity | Gravity Pro |
|---|---|---|
| Price | $699 | $749 |
| Composting process | Living microbial culture | Living microbial culture (identical) |
| Best for | 1–3 person households, typical food waste | Larger households or heavier daily scraps |
| Finish | Standard | Upgraded |
| Ongoing cost | Filter replacement only | Filter replacement only |
Who Should Get Gravity (Not Pro)
If you're a household of one to three people with a typical amount of daily food scraps — the usual mix of cooking trimmings, plate scrapings, and coffee grounds — the standard Gravity handles that volume comfortably. There's no compost-quality benefit to paying more if your daily input doesn't require the extra capacity. Most households fall into this category.
Who Should Get Gravity Pro
Gravity Pro makes sense when your kitchen consistently produces more food waste than a standard household — larger families, people who cook in bulk, or households that batch-process scraps less frequently and want more headroom between empties. If you've read our guide on choosing between Prime and Gravity and landed on Gravity because of its larger footprint over Prime, Gravity Pro is the next step up in that same direction — more capacity for the same core technology.

It's worth being explicit about what stays the same, since the $50 gap can make it feel like a bigger decision than it is:
- Compost quality — identical microbial process, identical real compost output
- What you can put in — both handle meat, dairy, and cooked leftovers the same way
- Maintenance — both need only periodic filter replacement, no subscription
- Odor control — same sealed, filtered design
A Few Real-World Scenarios
Specs are easier to apply when you can picture your own kitchen against them:
- A couple who cooks most weeknights, with occasional takeout — daily food waste stays modest and predictable. Standard Gravity fits comfortably, with room to spare between empties.
- A family of four or five with a lot of home cooking — more trimmings, more plate scraps, more coffee grounds on a daily basis. This is the profile where Gravity Pro's extra capacity starts paying off, since you're not emptying or feeding the chamber more often just to keep up.
- Someone who batch-cooks on weekends and generates waste in bursts rather than steadily through the week — Pro's larger capacity gives more buffer between those high-volume days, even if the weekly average looks similar to a smaller household.
If none of these describe your kitchen, you're very likely in standard-Gravity territory, and the extra $50 wouldn't change how the machine performs for you day to day.
How to Decide in 30 Seconds
Ask yourself one question: does your kitchen regularly fill a standard-capacity bin faster than you'd like to empty it? If yes, Gravity Pro's extra capacity is worth the $50. If your household's food waste is unremarkable — a few meals a day, typical scraps — Gravity is the right call, and the $50 is better spent on replacement filters or a compost sifter for finishing your output.
Frequently Asked Questions
Does Gravity Pro make better compost than Gravity? No. Both use the identical living microbial process and produce the same quality of real, soil-ready compost. The difference is capacity and finish, not composting performance.
Is Gravity Pro worth the extra $50? Only if your household's daily food waste volume regularly exceeds what a standard-capacity unit comfortably handles. For typical 1–3 person households, the standard Gravity is sufficient and the extra cost wouldn't change your results.
Can I upgrade from Gravity to Gravity Pro later? The two are separate units rather than an upgradeable component, so the decision is really about matching current household size and food waste volume to the right unit from the start.
Do Gravity and Gravity Pro use the same filters and parts? Both rely on the same periodic filter replacement model with no subscription — see our filter replacement guide for the maintenance schedule that applies to both.
How is Gravity different from Reencle Prime? That's a separate decision covered in our Prime vs. Gravity comparison — Prime and Gravity differ more substantially in size and design than Gravity and Gravity Pro do.
The Bottom Line
Don't overthink this one: Gravity and Gravity Pro make identical real compost through the identical process. The only question is whether your household's food waste volume needs the extra capacity Pro provides. Most households don't — but if yours regularly runs hot, the $50 upgrade buys real headroom, not a better machine.
