Complete voice IC, Bluetooth, and amplifier solutions for robot vacuum cleaner and floor scrubber manufacturers.
Supporting everything from basic status voice prompts to Bluetooth music streaming, AI voice control, and high-power audio alerts for commercial cleaning equipment.
Robot vacuum cleaners and floor scrubbers are evolving from silent mechanical devices into interactive smart home appliances. Clear voice status updates, Bluetooth music streaming, and AI voice control are becoming key differentiators for premium and mid-range cleaning robots, while commercial floor scrubbers increasingly need loud, reliable voice alerts for safety and operation status.
Voice feedback is no longer a nice-to-have — it’s becoming the new standard for smart cleaning equipment.
Beep codes are easy to misread. Voice prompts such as “Cleaning started,” “Dustbin full,” or “Returning to charging dock” remove ambiguity and reduce user confusion and support calls.
Brushless motors, suction fans, and wheel motors generate strong EMI. Waytronic voice and amplifier chips are designed for stable serial communication and clean audio output even in electrically noisy environments.
Robot vacuum cleaners run on rechargeable batteries. Ultra-low standby current voice ICs preserve battery life for both cleaning runtime and voice/alert functions.
Support customizable wake words, status prompts, and multilingual voice packs, allowing one hardware platform to serve multiple brands and export markets.
Waytronic has been providing voice IC and cleaning appliance solutions for over 26 years, helping manufacturers integrate voice prompts, Bluetooth audio, and voice recognition into robot vacuum cleaners, floor scrubbers, and other cleaning appliances.
From basic OTP voice prompts to AI far-field voice recognition, we offer voice ICs, Bluetooth audio chips, and amplifier solutions from 2W portable units to 80W commercial machines, designed for motor-driven environments with ultra-low standby current for battery-powered operation.

– UART/GPIO/I2C/ADC/PWM interfaces for easy MCU integration
– Works fully offline, no internet dependency
Scalable Amplifier Options From Compact Robots to Commercial Scrubbers
Different cleaning appliances need very different audio output power. Waytronic’s amplifier chip family lets manufacturers scale voice and alert volume without redesigning the voice IC platform.
Traditional designs often require separate MCU, voice IC, and multiple amplifier options sourced from different vendors. This increases:
– BOM cost
– Vendor management complexity
– PCB redesign effort across product tiers
– Development time
Recommended Chips by Power Tier:
WT8302 — 3W ultra-low EMI Class D, ideal for cost-sensitive robot vacuum cleaners
WT8871 — 5W Class AB/D selectable, no FM interference
WT9110B — 8.5W–20W, for mid-size floor scrubbers
WT8623 — 12.5W–35W, for commercial floor scrubbers requiring loud alerts
Beyond pre-recorded status prompts, Waytronic solutions also support:
Voice Recording: WT2003H-series recording chips let manufacturers or end users record custom voice content directly, useful for personalized status announcements or brand-specific greetings.
Multi-Language Voice Packs: App-side or factory-side text can be converted to voice content and loaded via TF card, U-disk, or serial update — supporting global product lines without hardware changes.
“Cleaning started,” “Returning to charging dock,” “Cleaning complete” — clear voice status removes the guesswork of beep codes and reduces customer support inquiries.
Voice alerts for low battery, dustbin full, brush jam, or wheel-lift detection help users respond quickly, improving the overall product experience.
WT2605-series Bluetooth audio chips let robot vacuum cleaners double as a Bluetooth speaker, streaming music from a connected phone while cleaning.
When hands are busy, users can simply say “start cleaning” or “go home.” WTK6900HA achieves reliable local recognition even with motor and fan noise present.
Supports Mandarin, English, and other languages through swappable voice files — ideal for manufacturers selling into multiple international markets from one hardware platform.
For commercial floor scrubbers, high-power amplifier options (WT9110B, WT8623) ensure voice alerts and warning tones remain audible in noisy industrial and retail environments.
