Market Context: The Rising Demand for Smart Cleaning
As global emphasis on hygiene intensifies, floor scrubbers have become indispensable for maintaining hard surfaces (cement, tile, marble, PVC). Yet, market saturation and price wars compromise quality and user experience. A critical gap persists: traditional scrubbers lack intuitive voice feedback, creating barriers for non-technical users. Waytronic’s WT588F/WTV/WT2003 series Voice Audio Chip address this by embedding cost-effective voice intelligence into cleaning systems.
Solution Architecture: Three Paths to Waytronic’s Voice Audio Chip
1. WT588F02B-8S Voice Audio Chip: The Economical Voice Engine
Core Features:
16-bit DSP @ 32MHz
2.0-5.5V operation (TTL-compatible UART)
Direct 8Ω/0.5W speaker drive (16-bit PWM)
Unique Advantage:
Real-time voltage monitoring with low-battery alertsImplementation:
2. WTV380-8S Voice Audio Chip: Power-Optimized Performer
Standout Capabilities:
Ultra-low sleep modes:
Normal Sleep: <30μA
Deep Sleep: <3μA
15 trigger modes (pulse/level/key-scan)
MP3 support @ 8-320kbps
User Workflow:
Power On → 5s Auto-Sleep → Wake-on-Command → Instant Playback
3. WT2003H4-16S Voice Audio Chip: All-in-One Control Hub
Technical Superiority:
Dual-channel audio (MP3/WAV @ 8-44.1kHz)
16-bit ADC/DAC + IIS host/slave modes
≤5μA deep sleep (with custom power management)
Role: Replaces primary MCU by handling:
Motor control
Sensor I/O (pressure, IR)
Display drivers

Implementation Scenarios
Senior-Friendly Cleaning:
Voice prompt: “Tank empty. Refill required.”
→ WT588F02B-8S Voice Audio Chip triggers alert via low-level sensor.
Commercial Efficiency:
Voice: “Deep-cleaning mode activated.”
→ WT2003H4-16S adjusts brush pressure via integrated ADC.
Safety Compliance:
Voice: “Obstacle detected. Reversing.”
→ For instance, the WTV380-8S processes IR sensor input during navigation.
Waytronic’s Vision: Engineering Simplicity
“We transform complexity into developer-centric solutions.”
By standardizing voice interactions across cleaning robotics, Waytronic empowers:
OEMs: Faster time-to-market with OTA-updatable voice libraries
End Users: Intuitive, multilingual operation
