- The “Pressure Stall”: Many budget-friendly scrubbers look powerful until you actually press them against the floor. If the motor is weak, the head will stop spinning as soon as you apply the pressure needed to clean deep grout.
- Battery Degradation: While 90 minutes of runtime is often claimed, real-world use at high speeds often drops this to 40 or 50 minutes.
- Bristle Durability: If the bristles are too soft, they will splay out within the first few uses, rendering the “pointed” brush useless for narrow grout lines.
- Water Resistance Limits: “Water-resistant” does not mean “waterproof.” A common point of failure is water entering the charging port if the rubber seal isn’t perfectly seated.
