Robot Vacuum Buying Guide

Key Selection Criteria 1: Intelligent Cleaning Mode Recognition

Recommended Feature: ADW Ultrasonic Material Recognition Sensor

Most robot vacuums can’t distinguish between hard floors and carpets.

ADW developed an ultrasonic material recognition technology, using a 300kHz high-frequency sensor.

This sensor detects how different materials absorb sound waves and uses echo detection to accurately identify surfaces like carpets or floors.

The robot then automatically switches to the correct cleaning mode for each surface.

Key Selection Criteria 2: Water Tank Alert System for Smarter Cleaning

Just like mopping carpets, dry mopping hard floors is another common failure.

Some robots don’t even realize their water tank is empty and continue "mopping" loyally -

You might wonder: "If I hadn’t seen this, would you keep dry-mopping until the end of your life?"

ADW Ultrasonic Water Tank Detection Sensor: ADW offers a water level warning solution using ultrasonic distance measurement.

It distinguishes between water and air by detecting the difference in sound wave travel speeds.

When water runs low, the sensor sends an alert, preventing ineffective cleaning and protecting your floors.
