Popur S7 Split Litter System review

The Popur S7 is an open litter system, but it is not an open globe. Its Split Litter System keeps the tray stationary while a powered sifter separates clumps, sends them through an exposed channel into a separate bin, and returns clean litter to the tray. That architecture is the central difference from the X5, whose tray/filter assembly uses a distinct cleaning layout. It changes the cat’s space and cleaning path, not the need for active care: this remains a powered mechanism that should be introduced gradually and operated as the manual directs.

A split tray rather than a rotating chamber

The S7’s tray is open above and accessible from three sides; the waste bin is a separate enclosed component. Popur’s current specification lists a 20.5 by 14.2 inch litter bed, 24.8-inch diagonal, and 8.3-inch depth, with a maximum fill of 8 liters or 25 pounds. The standard entry is about 10.6 inches, rising to 13.6 with an optional guardrail. That lower entry compared with some enclosed globes may be useful, but it is not step-free. A senior or short-legged cat still needs an honest transition and the optional stepper is not included by default. Numeric automatic-mode age and cat-weight cutoffs are not documented in the sources reviewed here; if one is a hard need, the matcher should not assume it from the open design.

Choose a clumping litter that suits the sifter

The included 6 mm sifter is intended for fine litter and smaller clumps. Popur offers 8 mm and 10 mm sifter alternatives for coarser particles, but they are separate options rather than automatically included in every offer. The FAQ recommends most clumping litter and describes the slot sizes as a way to choose between finer and larger granules. Non-clumping crystal is a poor fit because the machine separates formed clumps; a crystal type that physically falls through a gap does not make it a reliable clumping-litter system. If you already use a brand or pellet that breaks apart easily, check the manufacturer’s guidance before switching. A failed sieve match means fragments can travel with clean litter or clumps can remain behind.

Data and connectivity are optional tools, not diagnoses

The S7 supports an app with Bluetooth setup and dual-band Wi-Fi; Popur says basic cleaning can continue offline. Its app offers individual-cat activity and weight data when configured for those features. Weight readings are still sensors, not veterinary conclusions: Popur’s own technical clarification warns that litter shifts and environmental factors can affect measurements. Consider the records a prompt to observe your cat, not proof of a health condition. The maker also lists radar and weight-based presence checks and a Sentinel mode that can pause a cycle when movement is detected. Sensors and modes should not be described as guaranteeing that every animal is detected in every situation. Keep a supervised introduction, check the system and use a separate litter station if a cat refuses the new design.

Bin capacity, litter area and household size

The S7’s bin is listed at 11 liters, and the manufacturer advertises up to 35 days of waste for one average cat and up to 16 cats per machine. Those are manufacturer capacities, not a promise to delay inspection or to replace the litter boxes a multi-cat home needs for social comfort. Popur’s FAQ says the actual interval varies with diet, use, litter and bag-emptying frequency; it notes that high-use households can need a bag change every few days. For a multi-cat match, consider both station placement and the work needed to empty and clean the bin, not only the headline count.

Check the whole space before ordering. The listed body size including bin is 29.1 inches long, 20.5 wide, and 15.8 high; it needs 23.2 inches of headroom while the tray is lifted. It has four swivel casters and an integrated metal bin base, but a caster does not eliminate the need for a level, stable setup or service clearance. Measure around walls, the path to the room and the cord as well as the footprint.

Exact S7 choices and what changes from X5

At the inspected U.S. page, black and white are finish choices, and the offered warranty selectors are standard one-year or premium three-year. Those selector choices do not create four different cleaning mechanisms. The listed configuration includes one 6 mm sifter, the litter tray and chamber, bin base and hood, power cord, five elastic-band bags, and setup/manual materials; check the selected SKU and warranty wording at checkout. Compared with X5, the S7 adds the more substantial integrated base and dual-band connectivity, offers different sifter sizes, and documents individual-cat data. The X5 is shallower in its litter bed, uses an 8 mm standard filter and the basic Popur app. Compare the Popur X5 if you prefer its design or standard package; the X5 Core Bundle adds a plastic waste bin and extra supplies but does not become an S7.

Who should consider the S7?

Shortlist the S7 if an uncovered tray, clumping litter, a separate bin and its documented app data suit your household—and if you can accommodate the entry and cycle clearance. Its open layout is a meaningful distinction from a globe, but it does not prove cat acceptance, eliminate cleaning or establish an age/weight threshold. If the required litter is non-clumping crystal, the preferred entry is enclosed, or a specific automatic-use minimum is essential but undocumented, choose another operating plan or keep manual scooping available. Use the exact Popur S7 page, manufacturer FAQ and S7 user manual and resources to confirm the exact variant before purchase.
