Purobot Max Pro 2 Double Bundle Setup: Two Litter Boxes, One Household

Quick answer

Set up each Purobot Max Pro 2 in a separate, quiet spot with its own power outlet and at least a few inches of clearance around it. Unbox and test one unit at a time, then add accessories like the PETKIT Fence 2.0 to reduce scatter. Two automatic litter boxes work best when they are not side by side, so cats can choose a box without meeting a housemate on the way in.

Two automatic litter boxes are not just double the hardware. They change how cats move through your home, how often you empty waste, and how quickly you notice a problem. The Purobot Max Pro 2 double bundle setup works well when you treat each unit as its own station rather than a pair.

This guide walks through placement, power, onboarding, and the accessories that keep a two-box home cleaner. It also covers the small mistakes that make a double setup feel like more work instead of less.

Plan placement before you unbox

Pick two locations that are quiet, low-traffic, and easy to reach for cleaning. Avoid putting both boxes in the same corner, because a cat using one box should not have to pass the other to get in or out. A separate room, hallway, or opposite end of a large room usually works better than side-by-side placement.

Leave clearance around each unit for the lid, waste drawer, and any accessories. If you plan to add a ramp or fence, account for that space now rather than moving a heavy box later. Also confirm each spot has a nearby outlet, since extension cords across walkways are a trip hazard and a common reason setups get rearranged.

• Checkpoint: each box should have a clear entry path and no shared chokepoint.
• Mistake to avoid: placing both boxes against the same wall where one cat can guard the area.

Set up one Purobot Max Pro 2 at a time

Unbox and power on the first unit, complete its initial cycle, and let it run for a day before adding the second. This makes it obvious which unit needs attention if something behaves oddly. It also gives your cats a chance to investigate one new object instead of two at once.

Once the first box is stable, repeat the same process for the second. Keep the same litter type in both boxes so cats do not develop a preference based on texture. If you change litter, change it in both boxes at the same time to avoid one box becoming the favorite for the wrong reason.

• Checkpoint: both units complete a full cycle without errors before you rely on them.
• Mistake to avoid: introducing both boxes on the same day and losing track of which one has an issue.

Reduce tracking and odor at each station

Two boxes mean two exit paths, so tracking control matters more, not less. A ramp or mat at each entrance catches granules before they reach the rest of the room. Odor control also scales with the number of boxes, because each waste drawer produces its own smell over time.

Keep a simple routine: check both drawers on the same schedule, replace odor control on a set day, and wipe the entry area weekly. If one box is used far more than the other, that is useful information. It can mean placement, litter, or access needs adjusting, not that the second box is unnecessary.

• Checkpoint: both boxes get checked on the same day so neither is neglected.
• Mistake to avoid: treating the second box as a backup and only cleaning the busier one.

Introduce cats to both boxes gradually

Cats often accept a new box faster when the old routine still exists. Keep the previous setup available during the transition, then remove it once both new boxes are used regularly. Place a box near the old location if a cat is reluctant to travel to a new room.

Watch for signs that one cat is avoiding a box: hovering, eliminating just outside the entrance, or waiting until another cat leaves. These are placement and access problems more often than hardware problems. Adjusting location or adding an entry accessory usually helps more than changing the box itself.

• Checkpoint: each cat uses at least one box without hesitation within the first two weeks.
• Mistake to avoid: removing the old litter box before both new boxes are established.

Double bundle setup steps

1. Choose two separate locations: Pick quiet spots with clear entry paths, nearby outlets, and enough clearance for the lid and waste drawer. Avoid placing both boxes in the same corner. Checkpoint: neither box blocks the other's entry or exit.
2. Set up and test one box first: Power on the first Purobot Max Pro 2, run a full cycle, and let it settle for a day before unboxing the second. Checkpoint: the first unit cycles cleanly before the second is introduced.
3. Repeat for the second box: Set up the second unit in its own location using the same litter type, then confirm both complete cycles without errors. Mistake to avoid: introducing both on the same day and losing track of which unit has an issue.
4. Add entry and odor accessories: Fit the PETKIT Fence 2.0 or a washable ramp at each entrance, and place odor control in both waste bins on a monthly schedule. Checkpoint: both stations have tracking control and odor control, not just the busier one.
5. Transition cats and monitor use: Keep the old litter box available until both new boxes are used regularly, then watch for avoidance, hovering, or accidents outside the entrance. Next step: if one box is ignored, adjust its placement before changing hardware.

Accessories that make a double setup easier

• PETKIT Fence 2.0: A 2.8-inch elevated entrance accessory tailored for the PUROBOT MAX PRO 2 litter box, made from durable, non-toxic PP material that is odorless and easy to clean. Raising the entry point reduces litter scatter and helps minimize accidental urination outside the box, which matters more when two boxes create two exit paths.
• Cat Litter Ramp (Not suitable for Purobot Ultra): Made from washable ABS with a non-slip backing, it gives cats a stable step when exiting and helps reduce litter tracking. A stable exit step keeps floors cleaner at each station and is easier on cats that prefer a gradual step down.
• 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 5 rolls per pack. Having bags that fit properly makes emptying two waste drawers faster and more hygienic, so the routine is easier to keep.
• Pet Odor Eliminator N50 2.0: Controls odor in the waste bin, with one piece usable for 30 days and three pieces per pack. With two boxes, odor control doubles; a monthly replacement schedule keeps both waste bins from becoming the source of household smell.

A two-box Purobot Max Pro 2 setup works best when each unit gets its own quiet location, its own accessories, and its own place in your cleaning routine. Set them up one at a time, watch how your cats use them, and adjust placement before assuming the hardware is the problem.
