Vacuum. Mop. Map. Clean. The LEGEE-688 is HOBOT Technology's 4-in-1 floor cleaning robot. Where most robots vacuum or mop, the LEGEE-688 does both in a single pass — vacuum, dry mop, AI smart spray, and wet mop, in that order. Its patented FastBrush system vibrates the mopping cloth at 600–800 times per minute, and its temperature-controlled AI Smart Spray releases just enough water to dissolve stains without leaving water residue behind.

The Pro's Take: At Yard Automation Pros, the LEGEE-688 is our floor cleaning recommendation for homes with hard floors, pets, or kitchen grease. The 7 Talent Clean modes are the real differentiator — Kitchen Mode's two-pass stain system and Pet Mode's enhanced vacuum and spray make it a more capable daily driver than a basic sweep-and-mop robot. The LEGEE Smart Navigation gives it a real-time floor map, not just a random bounce pattern.

Core Features:

  • FastBrush 4-in-1 (Exclusive Patent): One pass handles vacuum, dry mop, AI smart spray, and wet mop simultaneously. Mopping cloth runs at 600–800 vibrations/min for active scrubbing.
  • LEGEE® Smart Navigation (Exclusive Patent): Five-sensor fusion — Laser, Encoder, Gyro, E-compass, and Position Estimation — delivers systematic, map-based coverage with three front lasers.
  • 7 Talent Clean Modes + Customized: Standard, Strong, ECO, Kitchen, Polish, Dry, Pet, and one fully user-configurable mode. Each mode independently controls spray, vacuum, mopping, and speed.
  • Kitchen Mode: Divides the floor into 1.5×1.5 m sections, makes two passes — first dissolves stubborn stains, second absorbs them.
  • AI Smart Spray: Temperature-controlled water dispensing. Just enough water to clean — no puddles, no slipping hazard.
  • D-Shaped Design + 4 cm Side Brush: Flat back edge and extended side brush reach corners and under cabinets that round robots can't access.
  • 500 ml Trash Bin + 320 ml Water Tank: Large-capacity bin with handle and app maintenance reminder. Water tank covers ~150 m² per fill.
  • Two-Layer Filtration: Washable screen filter (600#) catches large debris; HEPA filter catches fine particles.
  • Tangle-Free: Microfiber cloth system — no roller brush, no hair tangles.
  • Real Time Map + Cleaning Diary + Schedule Queue: Full session tracking in the HOBOT LEGEE App (iOS/Android, Wi-Fi).
  • Auto Return to Charge: 4M IR detection guides the robot back to base automatically.
  • Hard Floors Only: Tile, wood, laminate, marble, glass, epoxy. Not suitable for carpets.

Expert Q&A: Master Your Automation

Is the transition to an autonomous system complex?

Not at all. We have entered the era of the "Virtual Boundary." Most of our premiere units—including the Yarbo and LUBA 2—have eliminated the need for 'primitive' wire-trenching. Setup is managed entirely through a high-precision smartphone interface. By utilizing satellite-guided navigation, you can map your entire estate and have your robot operational in under 30 minutes.

Is wire-free setup actually reliable?

Yes. Our current generation of mowers and snow blowers (like Yarbo and Mammotion) utilize RTK-GNSS satellite positioning and 3D Vision. This creates a virtual boundary accurate to within 1-3 centimeters, eliminating the need for digging or perimeter wires entirely.

Is my specific property layout compatible with these robots?

We have specifically curated the Yard Automation Pro's collection to master the world’s most challenging topographies. From AWD mowers that conquer steep 38° slopes to ultrasonic pool bots designed for intricate infinity-edge designs, we carry a "Pro" solution for every environment. If you have concerns about unique obstacles or extreme terrain, reach out to us for a free, comprehensive property assessment.

Can these robots handle my specific slopes or pool type?

We specifically curate our collection for high-performance terrain. Our AWD mowers handle up to 38-degree inclines, and our pool bots utilize ultrasonic mapping for complex shapes. If you are unsure about your property, contact us for a free property assessment.

What happens if the robot encounters an obstacle (pet/toy)?

Safety is our "Pro" standard. Our units are equipped with a "Fusion" sensor suite—combining LiDAR, Ultrasonic sensors, and AI-driven cameras—to detect and bypass obstacles in real-time, ensuring a safe environment for families and pets.

How does the system handle inclement weather or rain?

Our autonomous fleet is engineered for the elements. Every unit is equipped with intelligent rain sensors and industrial-grade IPX waterproofing. At the first sign of a storm, your robot will automatically pause its cycle, return to the safety of its docking station, and remain sheltered until conditions are optimal. Once the weather clears, it resumes its mission exactly where it left off—ensuring your property remains perfect without you ever stepping outside.

What kind of support do I get after the purchase?

As an authorized dealer, Yard Automation Pros provides a dual-layer of protection. You receive the full manufacturer’s warranty plus our lifetime US-based technical support. We are here to help with mapping, app setup, and seasonal maintenance.
