The Next Wave of Smart Toilets: Beyond Heated Seats

The smart toilet market has matured. For the past decade, “smart” has been synonymous with “comfort”—heated seats, warm air dryers, and auto-open lids. These “Gen 1” features were impressive, but they were comfort layers added on top of a 100-year-old technology that still suffered from core problems.

We’ve all experienced them: the weak flush in an older home, the anxiety over hygiene, the unpleasant realities of odor and splash-back.

The next generation of smart toilets, “Gen 2,” is defined by a shift away from simple comforts and toward solving these fundamental plumbing and physics problems. A new wave of products is emerging that focuses on core performance—and it’s changing how we should shop for them.

Let’s decode the three key “Gen 2” problems and the new technologies designed to solve them, using the feature set of a model like the Hawkrown ST-PRO as a case study.

Problem 1: The “Weak Flush” & Low Water Pressure

The sleek, tankless design of many smart toilets hides a dirty secret: they are often heavily reliant on your home’s water pressure. In houses with older plumbing or low municipal pressure, these tankless models can suffer from weak, ineffective flushing.

Gen 1 Solution: None. You were simply told not to buy one.

Gen 2 Solution: Decouple the flush from home pressure. The new solution is a hybrid system: a built-in tank and a boost pump. * How it Works: Instead of relying on your home’s 2 GPM (gallons per minute) flow, the toilet’s built-in tank quietly fills. When you flush, the integrated boost pump (or “pump-assisted” flush) fires, ejecting the water with tremendous force, regardless of your home’s pressure. * The Objective Data: This isn’t just a “feels stronger” feature. It’s measurable. The “Maximum Performance” (MaP) score rates a toilet’s ability to remove solid waste in a single flush. A standard toilet might score 400-600 grams. A high-performance “Gen 2” model, like the Hawkrown ST-PRO, can achieve a 1000-gram MaP score, placing it in the highest tier of flushing power.

What to look for: Built-in Tank, Boost Pump, or MaP Score (aim for 800g+).

Problem 2: The “Splash & Odor” Dilemma

This is a problem of physics. Traditional toilets treat odor as an afterthought, using weak fans or scented cartridges to mask smells after they have escaped into the air. Splashes were simply accepted as unavoidable.

Gen 1 Solution: A simple deodorizing fan.

Gen 2 Solution: Prevent the problem at the source. The most innovative solution is the automatic foam shield. * How it Works: Before use (or upon sitting), the toilet dispenses a pre-emptive layer of dense, micro-bubble foam onto the water’s surface. This “foam shield” serves two functions. First, it acts as a physical barrier, creating a soft landing to completely prevent splash-back. Second, the foam layer traps odor molecules under the surface, preventing them from ever becoming airborne. * The Next Step: This is often paired with an active deodorizer, like a photocatalyst-free system, which continuously scrubs the bowl’s air, creating a catalytic reaction that converts odor compounds into harmless water and carbon dioxide, rather than just masking them.

What to look for: Foam Dispenser, Foam Shield, or Pre-use Foam.

Problem 3: The “Hygiene Anxiety” Paradox

For years, “hygiene” in smart toilets meant a self-cleaning nozzle. This was a good start, but it ignored a key question: what about the water being sprayed from that nozzle? In many homes, that water is the same tap water you might not even drink.

Gen 1 Solution: Self-cleaning nozzle (cleans the outside of the wand).

Gen 2 Solution: Purify the water before it ever reaches you. The new standard is UV water purification. * How it Works: As water is drawn from your supply line to the bidet, it passes through an internal chamber. Inside this chamber, a UV-C light (the same technology used in hospitals and water treatment plants) irradiates the water. * The Result: The UV-C light instantly neutralizes bacteria and microorganisms by destroying their DNA. The water that touches you is not just “tap water”—it’s been actively purified. This moves the hygiene conversation from “nozzle cleanliness” to “water-supply purity.”

What to look for: UV Purified Water, UV-C Sterilization.

Conclusion: How to Shop for a “Gen 2” Smart Toilet

The evolution of the smart toilet is clear. The first generation gave us comfort. The second generation is giving us performance.

When you are shopping, look beyond the heated seat. You can get a heated seat on a $200 add-on. A true, high-performance smart toilet is defined by its ability to solve core plumbing problems.

Ask yourself:
1. Does it solve flushing power? (Look for a Boost Pump or a MaP Score).
2. Does it solve hygiene? (Look for UV Water Purification).
3. Does it solve in-bowl physics? (Look for a Foam Shield).

When you find a model that prioritizes these “Gen 2” features, you know you’re not just buying a comfort item—you’re investing in a piece of next-generation engineering.
