# PETKIT Purobot Max 3 with N50 Automatic Cat Litter Tray

The PETKIT Purobot Max 3 with N50 is an automatic self-cleaning cat litter tray with a low entrance, app controls and a sealed waste bin. Its 76L size and claimed multi-cat suitability may appeal to homes seeking less manual scooping, while its 14.2-kilogram listed weight and 63.5 cm length call for space planning.

## At a glance

- Automatic cleaning is described as starting after the cat leaves, with waste deposited in a sealed bin.
- The listing claims a 7L waste bin can provide up to 15 days of automatic scooping convenience. Actual interval depends on use.
- App controls include cleaning modes, and the listing says the device records cat toilet frequency, duration and activity trends.
- A low-threshold entry and 76L interior are promoted for larger cats and multi-cat households.
- The included N50 2.0 deodorant is described as breaking down ammonia, with a stated 30-day filter life.

## Pros

- Low-entry design may be easier for older or short-legged cats to access.
- Sealed waste storage and the N50 deodorant system offer two mechanisms aimed at limiting odour.
- App-set cleaning options and weight-based cat identification are intended to make multi-cat tracking more manageable.
- Listing says the tray accepts clumping litter across several types, with a stated particle-length limit for bentonite.

## Cons

- At 63.5 cm long and 14.2 kg, it needs a substantial, planned location and may be awkward to move.
- The stated 18-pound maximum weight capacity may limit suitability for heavier cats.

## Less suited to

- Buyers without space for a tray measuring 63.5L x 54W x 55H centimetres.
- Cats above the listed 18-pound maximum weight capacity.
- Households wanting a maintenance-free system, since waste and the odour-control filter still require attention.

## Customer feedback

Customer feedback highlights ease of use, quiet operation, odour control, size and weight tracking, though some customers report problems with operation and experiences of cleaning and leak resistance are mixed. Positive comments about these features are relevant to this model’s app tracking, sealed waste bin and leak-control claims, but do not establish how consistently they perform. Value opinions are also mixed. The product rating is mostly positive overall, but ratings alone do not explain individual experiences.
- Positive themes: Customers are described as appreciating ease of use, quiet operation, odour control, size and weight tracking.
- Negative themes: Some customers reportedly say the product does not work properly.
- Mixed feedback: Feedback on cleaning and value for money is mixed.
- Mixed feedback: Leak-proof performance receives mixed feedback, despite reports of success with cats that urinate near the sides.

## Frequently asked questions

### How often does the waste bin need emptying?
The listing claims up to 15 days of use from its 7L bin. This is not a fixed interval, so plan to check and empty it according to your household’s use.
### Which litter can it use?
The listing says it works with clumping litter, including clay, tofu, mixed and bentonite types. It specifies a length under 1.27cm for the litter it describes.
### Does the tray track more than one cat?
The listing says the app identifies cats by weight and records toilet frequency, duration and activity trends. It does not establish how reliably this works in every household.
### What maintenance does the odour-control system require?
The listing describes an N50 2.0 deodorant and says each filter lasts 30 days. Treat this as a stated replacement interval, not a performance guarantee.
