Test Results
Waste Management Function
8.0
Our observation: The Petkit Purobot Max Pro delivers a major upgrade in waste isolation and disposal compared to earlier models. Its rotating drum, sealed waste bin, and no-touch drawstring sealing system reduce manual cleanup and odor exposure. The automatic waste-covering feature also improves cleanliness, especially for cats that don't bury waste. Maintenance Mode allows easier access for deep cleaning. While the setup is thoughtfully engineered, the drawstring waste system offers convenience, though optimal performance may vary slightly depending on litter type and user settings. As with any new model, long-term consistency in hands-free operation is still being observed.User feedback: Many owners praised the improved waste bin, easier cleaning access, and touch-free disposal. The waste-covering system stood out as a practical upgrade that reduced residual litter and odor. However, some users reported false cat detections halting cleaning cycles, and occasional sticking with wet litter types. Others noted the need for frequent refills of branded consumables like odor cartridges and bags. Despite these points, the Max Pro was still seen as a major improvement over traditional litter boxes and prior Petkit models.
Odor & Mess Control
7.0
Our observation: The Purobot Max Pro uses a triple-layer odor control system, including a tightly sealed waste bin, the N60 odor eliminator, and timed deodorizer releases. In theory, this setup should significantly limit unpleasant smells, and the sealed design helps prevent litter dust and ammonia buildup. However, performance may vary depending on litter type and user diligence with cartridge replacement. The anti-leak base and optional litter mats reduce external mess, but some scatter or residue can still occur, especially with high-velocity usage or wet clumps.User feedback: Users overwhelmingly noted a drop in noticeable odors compared to previous models or standard boxes. The new sealed bin design and solid deodorizer were frequently praised, especially in multi-cat homes. However, a few reviews reported lingering smells if cartridges weren't changed frequently or if litter stuck to the drum. While some found the mess containment improved, others mentioned occasional tracking or pad sticking with certain litter types. The unit's success in odor control appears strong overall but requires consistent maintenance and proper settings.
Cleaning & Maintenance Ease
7.0
Our observation: The Purobot Max Pro improves day-to-day upkeep with thoughtful features like Maintenance Mode (which rotates the drum for easier access), wipeable interior materials, and a hands-free drawstring disposal system. The sealed 360° drum and waste-covering feature help reduce stuck waste, and the redesigned base is reportedly easier to clean than earlier models. However, deep cleaning still requires full disassembly, and the unit is relatively heavy, which may be inconvenient for some owners. User feedback: Owners frequently praised how much easier the Max Pro is to clean compared to older Petkit models or competing brands like the Litter-Robot. Many appreciated the maintenance mode and non-stick barrel design. Still, some users reported wet litter sticking when delay settings weren't optimized, and others found the machine too bulky for frequent repositioning or deep cleaning. A few reviewers also mentioned that running out of PETKIT-specific liners or cartridges made the unit less functional until restocked.
Reliability & Durability
6.0
Our observation: The Petkit Purobot Max Pro is engineered with upgraded safety sensors, an anti-pinch entrance design, and a 360° sealed base intended to minimize jamming and leakage. The unit stops operating when pets approach, reducing the risk of accidents. Its rotating drum and motor system are built for quiet, consistent operation, and the sealed construction helps protect internal electronics from litter dust and urine exposure. While the structural design appears robust, full reliability over extended periods—especially in multi-cat households—has not yet been independently validated.User feedback: Many users reported consistent, quiet performance and appreciated the motion sensor's accuracy. However, a subset of critical reviews cited unreliable app-device pairing and false cat detections interrupting cleaning cycles. Others noted frustration with Wi-Fi connectivity and firmware stability. While the physical build quality received positive comments, software-related issues impacted perceived reliability in a minority of cases.
Cat Acceptance
7.0
Our observation: The Purobot Max Pro is designed with a spacious interior, low-entry design, and anti-pinch safety sensors to encourage cat comfort and safe use. Its quiet motor (rated 35-45 dB) helps minimize noise-related anxiety, and the built-in camera with multi-cat recognition allows owners to track usage patterns and behavioral changes. The internal space is large enough for most adult cats, and the sealed rotating drum provides a more enclosed, private toileting experience—factors that typically aid in acclimation. However, Petkit does not offer customizable entry steps or fences by default, which may limit accessibility for senior or mobility-limited cats.User feedback: Many users reported that their cats transitioned well from previous units or traditional boxes. Several reviews highlighted that even larger cats or those wearing cones used the unit without issues. The quiet operation was frequently mentioned as a positive factor. However, a few users noted hesitancy from skittish cats or initial resistance during the acclimation period. Some expressed a desire for a built-in ramp or lower entry height, particularly for older cats. Still, overall sentiment indicated successful adoption in multi-cat households.
Noise During Operation
7.0
Our observation: The Purobot Max Pro is advertised as operating at a noise level between 35-45 dB, which is quieter than many standard appliances and well-suited for placement in bedrooms or shared living spaces. The sealed drum design and upgraded motor system aim to reduce vibration and grinding sounds during cleaning cycles. While the unit is not silent, its sound profile is engineered to be unobtrusive for both cats and owners. No advanced sound-dampening enclosures or custom sound modes are included, which may be a factor for ultra-sensitive pets or noise-averse households.User feedback: Users generally confirmed the Max Pro runs quietly, with many stating it was significantly quieter than older models or competitor units. Some even placed it in bedrooms with no sleep disruption. A few reviews mentioned mechanical noise during rotation, but these were not described as loud or startling. No consistent complaints about noise-related issues with cats were reported, though some noted their pets initially reacted to movement during cleaning cycles before adapting over time.
