PETKIT MAX2: setup and cleaning notes for PuraMax 2 buyers

I set up a PETKIT MAX2 for my three cats. App tracking is handy, but a cleaning cycle left waste behind and threw away clean litter.

Introducing PETKIT’s Automatic Cat Litter Machine

Hello, everyone. Today I'm going to introduce the PETKIT automatic cat litter box. Technology makes life better. As you can see, this is a highly intelligent, appliance-style litter box. We need to plug it in at the back. As you can see, it needs to be plugged in. Once it's plugged in, the display lights up.

[Text: Warning: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Pet owners must strictly follow the instructions.]

It shows today's number of toilet visits, so it can track the data intelligently. As you can see, there are two buttons in total. A short press confirms. A long press turns it on or off, and a short press switches between functions. There's a cleaning function, a litter-leveling function, a maintenance function, and a reset function. There's also network setup. Let's take a look at this.

Waste Bag, Deodorizer, and Litter Choice

This “Open” section leads to the bag where the litter waste is collected. Oh. You can lift out the whole bag at once, and it is very light. This is where you put the deodorizer. For now, I'm using this Shuixianghua cat litter. It says it's cassava litter, but for cassava litter, I really think the amount is extremely small. The price is okay, though. I think it was around 100 or 200 yuan, for maybe 10 or 20 bags.

I remember they used to deliver it straight to your door, but I don't know why they don't offer that anymore. I had to carry a whole box of litter from our delivery station. It really wore me out. It was very uncomfortable. The smell is actually very fresh. The smell today is pretty nice.

Interior Design and Litter Loading

Let's take a look at the materials. The material looks a bit like stone chips, but it seems okay. Let's look at the structure inside the machine. This really is technical fabric. It's waterproof and urine-resistant. Make sure the green edge of the three-proof mat is fully fitted into the groove before use. Mm, and then... This is a rotating blade that moves the litter into the box. All right, enough talking. We'll pour the litter directly in here. The official claim is that this litter box holds more than 70 liters. It's very large.

It’s big, and there’s a lot of space. I've already poured three bags of litter into it. As for using litter as pet owners, whether it's a regular litter box or one like this, it's definitely better to put in more rather than less. That way, urine and so on won't stick to the bottom. If you put in too little, the urine will smear onto the bottom and be very difficult to clean. The only real advantage of this cassava litter is that it clumps well.

The urine and feces clumps come off easily with one scoop, which is a nice feature. As you can see, the display now shows an added weight of about 3 kg—wow.

[Text: Warning: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Pet owners must strictly follow the instructions. 3.1 kg added weight]

Each bag is labeled as 1.25 kilograms. So three bags should be 3.75 kilograms. The display clearly shows that we're short on weight. We're short on weight. I'm reporting you, Shuixianhua Cassava Cat Litter—you aren't playing fair. Here's a little pinky-finger salute for you.

Litter Levelling and the First Cat Visit

Now let's try out the functions. Let's try the litter-leveling function. All right. There it goes, moving over here. Our Debao, the cat who's closest and most familiar with me, couldn't wait to use his new toilet. Look at you, so brave, you rascal. Heh. Hey, hey. Well, look at you. You're really humoring me. This is so interesting. By nature, cats are burrowing animals. They like dark, private places for using the toilet, so this is pretty good. This really is excellent. The design is very clever.

It's starting to level the litter now. I think this function is pretty pointless. Even with a lot of litter, I don't think it makes any difference compared with patting it level by hand.

App Pairing and Wi-Fi Setup

It also requires us to download the PETKIT app. Once it's downloaded, it can identify and connect directly. This is related to Wi-Fi. As you can see, it's connecting now. It also shows that network setup is in progress and is being recognized automatically. Pretty high-tech.

[Text: Warning: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Pet owners must strictly follow the instructions.]

Okay, it says the binding was successful. It's checking the environment. It needs to be placed on a hard surface, with clearance left around it. Kitten mode.

[Text: Cleaning the three-proof mat — 5/6 The surface of the three-proof mat has a high-performance coating. Wipe it clean; do not scrub it, or its waterproofing may be affected.]

For cleaning this mat, it's telling us to wipe it with a wet wipe, not use a brush. This is how you pour in the litter. This should be cassava litter, a type of tofu litter.

Pet Profiles and Kitten Protection

There's also pet recognition. No pet added. Add one now. This is a Devon Rex. He's a neutered boy, and his nickname is Debao. His nickname is Debao. The little rascal is back in. The little cat is back again. You came in, you little... You're really brave. Pet age. He's already one year old. Almost two—born in 2024. Weight—oh, boy. He must weigh about 5 kg now. He's up to 5 kg. Okay, next step. Are there any kittens?

[Text: Initialization Kitten Protection The PETKIT Smart Cat Toilet MAX is suitable only for cats at least 6 months old and weighing 1.5–10 kg. Do you have any kittens at home? Yes No If you have a kitten or a pregnant cat close to giving birth, enable Kitten Protection for your cat's safety. Automatic (scheduled) cleaning will be disabled; you can tap “Clean Now” at a suitable time.]

I have two young ones—three-month-old Devon Rexes. Enable Kitten Protection mode. All right, that's done.

Remote Monitoring and Usage Data

Look here.

Today's toilet visits: 1 OK Short press to switch functions Long press to power on/off Short press to confirm the function Double-press OK to quickly level the litter]

It shows that Debao just left, and there has been one toilet visit today. Pretty smart.

Pet owners must strictly follow the instructions. Today's toilet visits: 1 Short press to switch functions; long press to power on/off Short press to perform the corresponding function; after using the litter box, double-press to level the litter]

It also says there has been one toilet visit today, with an average duration of 35 seconds. It can also be controlled remotely through the app, so when I'm not home, I can control it directly from my phone. It shows that there is plenty of litter left, the waste bin is normal, and since I didn't buy the deodorizing block, there isn't one. The odor eliminator isn't linked either. That's because we also have a very small Devon Rex at home.

It also has that kitten-protection mode enabled. If a kitten goes inside, for example, it won't automatically rotate and injure it. That's a really good feature. As you can see, I'm not home right now, and our cats have already made 11 toilet visits. That's really interesting. And now we can see some data here, such as when the peak period is, and each pet's weight. There's one over 3 kg, right? And another one that's 2.5 kg, and look, there's one over 5 kg too.

This guy's gotten fat. Then he came out. Not bad. How many seconds did he take? He's constipated. It seems to have taken more than ten minutes. Obviously, he was playing in there.

A Busy Day and the Automatic Cleaning Demo

Oh, when I got home, it was a disaster.

[Text: Warning: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Pet owners must strictly follow the instructions. Today’s litter-box visits]

These three cats are two larger ones and one smaller one.

They made 19 toilet visits today. The moment I walked in, a wave of stink hit me. Wow, let's switch it to automatic cleaning mode now.

[Text: Warning: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Pet owners must strictly follow the instructions. Today’s litter-box visits]

Clean now.

[Text: Warning: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Pet owners must strictly follow the instructions.]

Let me demonstrate how it cleans the waste.

Cleaning Results: Leftover Waste and Wasted Litter

As you can see, after one minute, it's basically finished cleaning. Judging by the results, I think it's okay. Basically, standing by the door now, I don’t smell that stench anymore. But there is still some feces inside that it didn't remove. This is the waste bin. Look here.

[Text: 1. Do not use with kittens under 6 months old. 2. Do not use with cats weighing less than 1.5 kg. Improper use may cause accidental injury to your pet. Read and follow the safety instructions carefully before use.]

It mistakenly removes quite a lot of litter, so it also discarded a lot of perfectly good litter. Look, this is all good litter. It hasn't even been used. That's quite wasteful. It seems to be rather poor at identifying feces.

Before You Buy

Models in your region

The owner identifies the machine as the Chinese-market PETKIT MAX2, but does not provide a complete model number. The regional products below are related PuraMax models rather than confirmed relabels; exact firmware, bundle contents and market equivalence remain unconfirmed.

What to know
This is a related UK-market comparison to the owner’s Chinese MAX2. It is not confirmed to be a relabel of the owner’s machine, and the owner’s Chinese-market functions and setup should not be assumed identical.

What the owner actually tested

The video shows installation, litter loading, app pairing and initial use, rather than a documented long-term ownership period. The owner first mentions two three-month-old Devon Rex kittens, but later describes the observed group as two larger cats and one smaller cat; the account does not resolve that inconsistency. The owner reports 19 litter-box visits in one day, a one-minute cleaning demonstration and reduced odour at the doorway, but some faeces remained inside.

The owner says the litter-levelling function makes little practical difference and that the machine removes a noticeable amount of unused, clean litter with the waste. That is a single household observation using the owner’s chosen litter, not an independently measured loss rate.

Safety and kitten use

The warning on the machine prohibits use by cats younger than six months or weighing under 1.5 kg. Separately, the app states suitability for cats at least six months old and within 1.5–10 kg. The owner enables kitten protection, which the app says disables automatic scheduled cleaning and allows manual cleaning at an appropriate time. That setting does not establish suitability for a three-month-old kitten contrary to the age restriction.

App features and operating setup

The owner pairs the machine with the PETKIT Pet app over Wi-Fi and reports toilet-visit counts, average visit duration, litter status, waste-bin status, pet profiles and weight data. The owner also says the machine can be controlled remotely, although this video does not independently test operation over a long absence.

The machine needs a hard, stable floor with clearance around it, according to the owner’s setup instructions. The owner also shows a wipe-clean instruction for the three-protection mat and says not to scrub it with a brush. Buyers should verify the cleaning instructions for their exact regional unit.

PETKIT PURA MAX P9902 (T4) · International English manual

Regional buying context

US buyers are looking at PETKIT PuraMax 2 rather than a confirmed identical Chinese MAX2. The official US product lists a 7 L waste bin, a low entrance, app usage tracking and an upgraded seamless ShieldBase cylinder; its official bundle includes a two-year warranty, while bundle contents differ from standalone purchases.

UK buyers can find PuraMax 2 with PURA Air. The listing identifies an upgraded seamless ShieldBase cylinder, but it does not confirm identical firmware, accessories or internal construction to the Chinese-market MAX2 in the owner’s video. The owner’s cleaning and waste-separation observations therefore should not be treated as UK-model test results.

The supplied international manual identifies the original PETKIT PURA MAX P9902/T4 at 620 × 538 × 552 mm and about 9.5 kg including its adapter, using 12 V and 24 W. It is an original MAX-family reference, not proof that those specifications apply to the owner’s Chinese MAX2 or to PuraMax 2.
