Open One vs Pro vs QClean: Which Petbuds Litter Box Is Right for You?

Three models, three very different households. Here's how to tell which one is actually right for yours.

The Three Models at a Glance

Specs current as of 2026. Check each product page for the latest pricing and full spec sheet.

Open One: The Easy Starting Point

Open One is the open-top, low-entry model in the lineup, and it's deliberately built that way. An open top with a low step keeps the box feeling familiar to a cat who's used to a standard tray, which is exactly why it tends to suit nervous or first-time automatic litter box users best. It's the most accessible entry point into automatic cleaning, both on price and on how little adjustment your cat has to make.

Best for: single-cat households, apartments with limited floor space, owners who want to trial an automatic litter box without the highest upfront cost, and cats who are likely to be hesitant about an enclosed unit.

Worth knowing: because it's open-top, odour containment relies entirely on the sealed waste bin rather than an enclosed hood, so bag changes should be kept on a regular schedule, especially in smaller rooms.

Pro: The All-Rounder Most Households Choose

Pro is the model most Petbuds customers land on, and for good reason — it's built to handle a typical Australian household without asking you to compromise. Two things set it apart from cheaper enclosed units on the market: a built-in odour elimination port that actively breaks down smell rather than just sealing it away, and a noticeably quieter motor than older-generation enclosed boxes, which matters if the unit sits in a living area or near a bedroom.

Best for: most homes, including 2-3 cat households, anyone who's previously been put off automatic litter boxes by smell or noise complaints, and households wanting the strongest balance of price, features, and reliability.

Worth knowing: Pro runs on the Smart Life app rather than Tuya, and auto-clean is disabled below 1kg cat weight as a safety measure, so it's not the right choice for very young kittens until they're past that threshold.

QClean: Built for Bigger, Busier Households

QClean is the flagship model, built around a more efficient motor and a smart odour deodoriser. The more efficient motor cycles faster and more quietly under heavy daily use, which matters most in households where the box is getting used constantly by more than one or two cats, while the smart deodoriser actively manages odour rather than relying on the sealed bin alone.

Best for: multi-cat households, larger-breed cats, and owners who want the most advanced motor and odour management available without sacrificing reliability under heavy daily use.

Worth knowing: it's the largest footprint of the three, so measure your space before buying, particularly if it's going into a bathroom or laundry rather than an open living area.

Match It to Your Situation

One cat, small apartment, first automatic litter box: Open One. Lowest barrier to entry, easiest adaptation, smallest footprint.

One to three cats, typical home, want it to "just work": Pro. The odour port and quieter motor solve the two most common complaints people have about automatic litter boxes generally.

Three or more cats, or a larger-breed cat: QClean. The more efficient motor and smart deodoriser are built to handle constant heavy use without the odour or noise trade-offs of cheaper enclosed units.

Tight budget, just want to stop scooping daily: Open One gets you the core benefit, daily hands-off cleaning, at the lowest cost of entry.

Who Shouldn't Buy Each Model

Skip Open One if: you have more than one cat sharing the box regularly, or you're in a small, poorly ventilated room where open-top odour exposure would bother you between bag changes.

Skip Pro if: you have three or more cats sharing one unit under constant heavy use, in which case QClean's more efficient motor and smart deodoriser are built to handle that load better.

Skip QClean if: you have limited floor space or only one cat, since you'd be paying for a feature set built for heavier use than you need. Pro covers most single and dual-cat homes at a lower price point.

Frequently Asked Questions

What's the real difference between Pro and QClean?
The two biggest differences are motor efficiency and odour control approach. QClean uses a more efficient motor built for heavier, more frequent multi-cat use, plus a smart odour deodoriser, while Pro uses a built-in odour elimination port and a quieter standard motor suited to most single and dual-cat households.

Is Open One suitable for kittens?
Open One's auto-clean cycle requires a minimum cat weight of 1.2kg and is not recommended for kittens under six months old, regardless of weight, as a safety precaution.

Which model is quietest?
Pro is built around a noticeably quieter motor than older-generation enclosed units, making it the best pick for placement near a bedroom or open living space.

Can I run two cats on one Open One unit?
It's possible for two cats to share an Open One, but Pro or QClean's enclosed design and stronger odour control are better suited to consistent multi-cat use.

Do all three use the same app?
No. Open One runs on the Tuya app, while Pro and QClean both run on Smart Life. They are not interchangeable, so check which app applies before setup.
