PETKIT Purobot Crystal Duo (automatic litter box with an open tray for cats): our review

A cat can have firm opinions about bathroom arrangements. The Purobot Crystal Duo has an open tray, making it worth considering if an enclosed toilet seems an awkward proposition for your household. We like that straightforward layout: the buying decision starts with somewhere your cat will willingly go.

Does your older cat hesitate before stepping over the edge of the tray? The entrance threshold is 18 cm, a low step that may make each visit easier to manage. That matters when the tray sits beside the washing machine and your cat wanders in while you sort the laundry.

The manufacturer sets a minimum cat weight of 1.5 kg, so a growing kitten needs particular care. Manufacturer instructions require kittens below that limit to stay out of automatic mode. An open entrance does not remove that restriction.

Silica is the verified compatible litter here. That is the decision to settle before choosing the appliance: if you prefer clumping litter, this model does not fit your routine. The litter matters as much as the mechanism.

Waste management uses a disposable waste bin, while the litter tray is replaceable. These are practical details for the cupboard where you keep cat supplies: replacement bins and trays belong in your ongoing shopping routine. Automatic cleaning still leaves you responsible for checking the tray and dealing with waste. Your cat is unlikely to volunteer.

Before ordering, check that compatible silica and replacement consumables are readily available. For a neighbour looking after the cat during a holiday, leave clear instructions and the necessary supplies together. A simpler handover starts with an organised cupboard.

The Purobot Crystal Duo includes a visit counter and visit duration tracking. Those records give you something more concrete than wondering whether the cat spent longer in the tray while you were busy putting the kettle on. They describe visits; they do not explain the reason behind a change.

Would a record of those comings and goings help you keep track of an otherwise busy day? We see a useful role for it, provided unusual habits lead to a conversation with your vet rather than reassurance from a counter.

PETKIT also states that the appliance has presence detection and automatically shuts off when a cat is present. These are manufacturer descriptions, not a promise of safety. Follow the manufacturer's gradual introduction guidance, initially leaving the appliance switched off or in manual mode with the familiar tray alongside.

Our preference here rests on the combination of an open tray, a low entrance and an appliance weight of 5.65 kg. That weight should make moving it by yourself straightforward when you need to clean the bathroom floor or reorganise the utility room. Being able to shift the appliance matters beyond delivery day.

For a cat accustomed to an open toilet, this is a coherent option to consider. If your cat prefers an enclosed space, we would let that preference guide the choice instead. Familiar habits deserve more influence than enthusiasm for another appliance.

The practical appeal is quite specific: accessible entry, visit records and replaceable tray components. Choose it because those details suit the household you have. The cat already has enough influence over the furniture without an unsuitable toilet joining the negotiations.
