Purobot Max Pro 2 2台セットと単体どっちを買う？

Quick Answer

If you have two or more cats or want one box per floor, the Purobot Max Pro 2 Double Bundle is the stronger buy because it pairs a full litter, feeding, and hydration setup with a second automatic box. If you have one cat and limited floor space, a single unit is simpler and cheaper to maintain. The Purobot Max 3 Double Bundle is the alternative when you want two of PETKIT's third-generation box rather than the mixed bundle.

Shopping for an automatic litter box gets confusing fast once bundles enter the picture. PETKIT sells a Purobot Max Pro 2 Double Bundle that combines an AI litter box with a dual-hopper feeder and a water fountain, and it also sells a Purobot Max 3 Double Bundle built around two third-generation boxes. Both look like 'two boxes for less,' but they solve different problems.

This comparison uses only the supplied catalog facts, so you can see exactly what each bundle includes, what it does not, and which one matches your household. The goal is not to crown a winner, but to help you pick the setup you will still be happy with six months from now.

What the Purobot Max Pro 2 Double Bundle Actually Includes

The Purobot Max Pro 2 Double Bundle is not two of the same litter box. It bundles the Purobot Max Pro 2 AI Smart Litter Box with the YumShare Dual-Hopper 2 feeder and the EverSweet Ultra fountain. PETKIT describes the trio as smart care for every part of the pet's day: personalized meals, fresh water, and automated litter management in one purchase.

That matters because the bundle covers three chores, not one. If you are currently juggling a separate feeder, a fountain, and a litter box from different brands, this is the bundle that consolidates them. The trade-off is that only one of the three devices is a litter box, so a two-cat home still needs a plan for the second box.

• Best value if you are upgrading feeding, hydration, and litter care at the same time.
• Check whether you already own a feeder or fountain you like before paying for replacements.

What the Purobot Max 3 Double Bundle Changes

The Purobot Max 3 Double Bundle takes the opposite approach: two of the same third-generation automatic litter box. PETKIT lists a low, wide entry, a 7L side waste bin rated for up to 15 days of hands-free use, a 4-part OdorVoid Defense System, and a patented 360° ShieldBase Leak-Guard against edge leaks.

For a multi-cat home, two identical boxes mean two waste bins and two separate litter stations, which is often the real bottleneck. The trade-off is that this bundle does not include a feeder or fountain, so you would buy those separately if you want the full routine covered.

• Two boxes reduce queueing when cats refuse to share a litter station.
• Budget separately for a feeder and fountain if you want the same coverage as the mixed bundle.

Single Unit vs Double: The Real Trade-Off

A single automatic litter box is easier to place, easier to clean around, and cheaper to keep in consumables. The Purobot Max 3's 7L side waste bin is rated for up to 15 days, so one box can genuinely carry a small household. The downside shows up with two or more cats: one box means one waste path, one odor source, and more frequent emptying.

A double setup spreads that load, but it also doubles the footprint and the accessory spend. PETKIT's own accessories make the ongoing cost visible: the Automatic Litter Box Trash Bag fits PuraX, PuraMax, PuraMax 2, and Purobot Max 3, and the Refill Ring is built for the Purobot Ultra. Neither accessory is listed as compatible with the Purobot Max Pro 2 in the supplied facts, so confirm consumables for your exact model before buying two of anything.

• Count cats first, then count floors: two cats on two floors usually need two boxes.
• Add up bags, pads, and refills for two units before comparing bundle prices.

Accessories and Consumables to Plan For

Bundles lower the entry price, but consumables decide the long-run cost. The High Performance Cat Litter Pad Max 3.0 is designed to work with the upgraded cylinder to prevent urine leakage inside the automatic litter box, with a waterproof surface and an anti-stick finish. If you run two boxes, you are buying two of these on the same schedule.

The Automatic Litter Box Trash Bag comes five rolls per pack with a tear-resistant drawstring design, and the Refill Ring uses leak-proof PE material with NFC recognition and visible warning marks. Both are practical, but each is tied to specific models. Treat accessory compatibility as a checklist item, not an afterthought.

• Match every accessory to the exact model name before checkout.
• Buy consumables in the same order as the bundle so you are not caught short in week one.

Trade-Offs at a Glance

• Coverage vs. duplication: The Purobot Max Pro 2 bundle covers litter, feeding, and hydration but includes only one litter box. The Purobot Max 3 Double Bundle covers litter twice but leaves feeding and water to you. Pick based on which chore hurts most right now.
• Footprint vs. convenience: Two boxes mean two stations to place, power, and clean around. One box is easier to fit but concentrates waste and odor in a single spot. Measure your floor space before choosing the double setup.
• Upfront bundle price vs. ongoing consumables: Both bundles lower the entry cost versus buying separately, but pads, bags, and refills scale with the number of boxes you run. Estimate monthly consumables for the whole household, not per unit.
• Model-specific accessories: The Automatic Litter Box Trash Bag lists PuraX, PuraMax, PuraMax 2, and Purobot Max 3, while the Refill Ring is built for the Purobot Ultra. The supplied facts do not list the Purobot Max Pro 2 for either. Confirm compatibility with PETKIT before buying accessories in bulk.

Product Facts Behind This Comparison

• Purobot Max Pro 2 + YumShare Dual-Hopper 2 + EverSweet Ultra: PETKIT describes this bundle as smart care for every part of the pet's day, combining the Purobot Max Pro 2 AI Smart Litter Box with the YumShare Dual-Hopper 2 feeder and the EverSweet Ultra fountain for personalized meals, fresh water, and automated litter management. It is the only option here that covers feeding, hydration, and litter in one purchase, which suits owners replacing three separate devices.
• Purobot Max 3 Double Bundle: The PUROBOT MAX 3 is PETKIT's third-generation automated litter box built for all breeds and ages, with a low, wide entry, a 7L side waste bin for up to 15 days of hands-free convenience, a 4-part OdorVoid Defense System, and a patented 360° ShieldBase Leak-Guard. Two of these give multi-cat homes two full-size waste bins and two entry points, which reduces queueing and odor concentration.
• High Performance Cat Litter Pad Max 3.0: This pad works with the upgraded cylinder to prevent urine leakage inside the automatic litter box, with a waterproof surface, an anti-stick feature, and scratch resistance. It is a recurring consumable, so running two boxes means buying and changing twice as many pads.
• Automatic Litter Box Trash Bag: Fits PETKIT automatic litter boxes PuraX, PuraMax, PuraMax 2, and Purobot Max 3, with a tear-resistant drawstring design and five rolls per pack. The compatibility list is model-specific, so verify it against whichever box you choose before stocking up.

Which Setup Fits Your Home

Best for

• Two or more cats, or one cat with a second litter station on another floor
• Owners replacing a feeder, fountain, and litter box at the same time
• Households that want two full-size waste bins and two entry points

Not for

• Single-cat homes with limited floor space, where one box is enough
• Shoppers who already own a feeder and fountain they are happy with
• Anyone unwilling to budget for double the pads, bags, and refills

Choose the Purobot Max Pro 2 Double Bundle if you want one purchase to cover meals, water, and litter, and a single box genuinely serves your cats. Choose the Purobot Max 3 Double Bundle if the bottleneck is litter capacity and you want two third-generation boxes instead. Either way, confirm accessory compatibility for your exact model before you stock up.
