Beginner's Guide: Carpet Cleaning Products and Tips

Carpets and rugs add warmth, style, and comfort to any home. But over time, they also collect dust, allergens, pet hair, and stains—making regular carpet cleaning essential not only for appearances but also for a healthier living space. Whether you're deep-cleaning a plush area rug or trying to maintain wall-to-wall carpeting, knowing the right carpet cleaner, tools, and methods for each carpet type is key to success.

In this comprehensive guide, we’ll cover everything you need to know about carpet cleaning, including tried-and-true tips, carpet and rug cleaning products you should have, DIY methods, and modern solutions like robotic vacuums. 

Why Carpet Cleaning Matters

Carpets act like giant filters, trapping dirt, bacteria, and allergens. Over time, these particles accumulate and not only make carpets look dull but can also affect air quality and even contribute to allergies. Proper rug cleaning and carpet care extend the life of your carpet and improve your indoor environment.

Whether you're dealing with everyday debris, deep-seated pet hair, or stubborn stains, regular cleaning is essential—and easier than you think with the right strategy.

Carpet Cleaning Tips for Everyday Maintenance

1. Vacuum Frequently

Vacuuming is your first line of defense against dirt and dust. For high-traffic areas, aim to vacuum at least twice a week. Low-traffic areas can get by with once-a-week maintenance.

  • Use slow, overlapping strokes.
  • Pay special attention to edges and corners.
  • Empty the vacuum dust box regularly for maximum suction.

Use a handheld vacuum cleaner or robot vacuum with strong suction power for daily carpet cleaning. If you have pets or children, consider a robot vacuum that can run daily to stay ahead of the mess.

2. Address Spills Immediately

The faster you act, the better your chances of preventing a stain.

  • Blot (don’t rub) the spill with a clean cloth or paper towel.
  • Use a carpet-specific spot cleaner or a mixture of mild dish soap and warm water.
  • Rinse the spot with a clean damp cloth and blot dry.

3. Deep Clean Regularly

Even if you vacuum religiously, dirt eventually settles deep into the fibers. Experts recommend a deep carpet cleaning every 6–12 months using either professional services or a home-use carpet cleaner.

Carpet and Rug Cleaning Products

Having the right tools makes all the difference. Here’s what you should have in your carpet-care arsenal:

1. Traditional Vacuum Cleaner

A good upright or canister vacuum with a rotating brush roll is essential. For delicate rugs, use the suction-only setting to avoid damaging the fibers.

2. Carpet Cleaner (Machine)

These machines spray a cleaning solution deep into the carpet, then suction out the water and debris. They’re ideal for deep cleaning high-traffic areas or stubborn stains.

3. Spot Cleaners

Portable spot cleaners or handheld units are great for dealing with spills, pet messes, and localized stains.

4. Steam Cleaner

Steam cleaners use hot water vapor to break down grime and sanitize surfaces. However, always check your carpet type—some materials like wool don't respond well to steam.

5. Robot Vacuums

For modern homeowners, a robot vacuum is a game-changer. These devices automatically navigate your home, vacuuming dust and debris daily to maintain clean carpets with zero effort.

LDS vs dToF LiDAR Navigation in Robot Vacuums

Have you ever wondered how your robot vacuum cleaner seamlessly navigates around furniture, avoids pet toys, and maps your entire home without constant human guidance? The secret lies in its navigation technology—primarily either LDS LiDAR or dToF LiDAR. These sophisticated systems are the "eyes" of your robot cleaner, enabling it to understand its environment and clean efficiently.

In this blog, we'll dive deep into these two technologies, explore how they work, compare their strengths and weaknesses, and help you understand which might be better for your needs.

How LiDAR Technology Works in Robot Vacuums

LiDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure variable distances to an object. These light pulses—combined with other data recorded by the system—generate precise, three-dimensional information about the shape of the object and its surface characteristics.

In the context of robot vacuums, LiDAR technology is crucial for simultaneous localization and mapping (SLAM). SLAM algorithms allow the robot to construct a map of an unknown environment while simultaneously tracking its location within that map. This is why modern robot vacuums can clean methodically rather than just bouncing randomly around your room.

There are different implementations of LiDAR technology in consumer robot vacuums, with LDS LiDAR and dToF LiDAR being two prominent approaches in the robot vacuum market.

What is LDS LiDAR?

3i P10 Ultra with LDS LiDAR Mapping

LDS (Laser Distance Sensor) LiDAR is currently the more widespread navigation technology in robot vacuums. It mainly works through triangulation measurement with a rotating laser component.

How LDS LiDAR Works

  1. A laser diode emits laser beams in multiple directions through a rotating module.
  2. These beams hit obstacles and objects in the environment and reflect back to the sensor.
  3. The system uses triangulation to determine distances.
  4. By repeating this process thousands of times per second while moving, the robot builds a detailed map of its surroundings.

Characteristics of LDS LiDAR

  • Mechanical Rotation: LDS LiDAR relies on a physically rotating component to emit laser beams in all directions, which allows for 360-degree scanning.
  • Established Technology: It's a more mature technology that has been widely adopted in mid-to-high-end robot vacuums.
  • Physical Profile: Due to the rotating mechanism, LDS LiDAR modules typically require a protrusion on top of the robot vacuum, which can increase the overall height of the device.

What is dToF LiDAR?

3i G10+ with dToF LiDAR Navigation

dToF (direct Time-of-Flight) LiDAR is a more recent advancement in sensing technology that's gaining traction in premium robot vacuum models. Unlike LDS, dToF measures the exact time it takes for a laser pulse to travel to an object and back to the sensor.

How dToF LiDAR Works

  1. The system emits short pulses of laser light across a wide area.
  2. A specialized sensor measures the precise time it takes for each pulse to bounce back from objects in the environment.
  3. Using the constant speed of light, the system calculates distances directly from the flight time of these pulses.
  4. This process happens extremely quickly, creating a detailed depth map of the surroundings.

Characteristics of dToF LiDAR

  • Solid-State Design: Many dToF systems are solid-state or semi-solid-state (using Micro-Electro-Mechanical Systems, or MEMS mirrors), meaning they have fewer or no moving parts compared to LDS systems.
  • Higher Accuracy and Range: dToF typically offers higher measurement precision (potentially down to millimeter level), a longer detection range, and maintains accuracy better over distance.
  • Compact Profile: Without bulky rotating parts, dToF modules can be made more compact and flat, allowing for lower overall height of the robot vacuum. This enables cleaning under low furniture.

LDS LiDAR vs. dToF LiDAR: A Detailed Comparison

The following table summarizes the key differences between these two technologies:

Feature

LDS LiDAR

dToF LiDAR

FAQ: Common Questions About LDS and dToF LiDAR

Q: Which technology is better for robot vacuums?

A: There's no definitive "better" technology—it depends on your priorities. LDS LiDAR offers proven performance and excellent value for money. It's a mature, reliable choice for most households. dToF LiDAR generally provides higher accuracy, better performance in challenging lighting conditions, and often enables a lower-profile robot that can clean under low furniture. However, it typically comes at a higher cost. 

Q: Can these technologies see colors or recognize specific objects?

A: No, both LDS and dToF LiDAR are primarily distance-measuring technologies. They create point clouds or depth maps by measuring the time it takes for light to return, but they do not capture color information or inherently recognize objects like a camera does. However, many advanced robot vacuums fuse LiDAR data with input from cameras (for visual recognition) and other sensors to better identify specific obstacles like shoes, cables, or pet waste.

Q: How well do they work in complete darkness?

A: Both LDS and dToF LiDAR work excellently in complete darkness since they rely on their own emitted laser light for perception, not ambient light. This is a significant advantage over vision-based navigation systems, which can struggle in low-light conditions.

Q: Which technology is more future-proof?

A: dToF represents a newer trend in consumer technology and aligns with the industry's move towards solid-state solutions (with no moving parts), which can offer increased reliability and compactness. Furthermore, its inherent advantages in range, accuracy, and light resistance are beneficial. However, LDS is a highly mature and cost-effective technology that will likely remain relevant and effective in the mid-range market for years to come. Innovations might also focus on sensor fusion—combining the strengths of different technologies, like dToF for navigation and dedicated AI cameras for obstacle recognition.

Q: Do I need to clean these sensors?

A: Yes, periodic gentle cleaning is recommended for both types of sensors. For LDS LiDAR, the rotating module on top can collect dust and should be wiped clean with a soft, dry cloth. For dToF sensors, the window covering the solid-state emitter and receiver should be kept clean from smudges, dust, or debris that could potentially interfere with measurements. Always refer to your specific robot vacuum's manual for cleaning instructions.

Conclusion

Both LDS LiDAR and dToF LiDAR are impressive technologies that have revolutionized how robot vacuums navigate our homes. LDS LiDAR offers a cost-effective, reliable, and proven solution that has successfully powered a generation of smart robot vacuums. dToF LiDAR represents a more advanced approach with potential advantages in accuracy, range, form factor, and adaptability to challenging conditions, often found in premium models.

The choice between them isn't always straightforward. When selecting a robot vacuum, consider factors like your budget, home layout (especially the amount of low furniture), the presence of challenging surfaces like glass or mirrors, and the importance of cutting-edge features.

Ultimately, the best technology is the one that reliably helps your robot vacuum keep your home clean with minimal intervention. As technology continues to evolve, we can expect these systems to become even more accurate, efficient, and integrated into smarter home ecosystems.

Roller Mop of 3i S10 Ultra Robot Vacuum and Mop
Comparing Mop Pads in Robot Vacuums: Flat Mops vs Dual Spin Mops vs Roller Mops

Robot vacuums have transformed home cleaning by bringing hands-free vacuuming into daily life. But in recent years, the capabilities of both vacuuming and mopping have made these devices even more versatile. As mopping tech advances, one thing becomes increasingly clear: not all robot mop pads are created equal. The type of mop pads—and the technology behind it—directly affects how well your robot can handle dirt, sticky spills, and everyday messes.

In this blog, we’ll explore the three most common types of mop pads found in robot vacuums: flat mop pads, dual spin mops, and roller mop systems. We'll evaluate them based on cleaning performance, ease of maintenance, floor compatibility, and more. Finally, we’ll take a closer look at the 3i S10 Ultra, a next-generation robot vacuum with a real-time self-cleaning roller mop, showing how it's redefining mopping performance.

Flat Mops

Flat mop pads are the simplest and most widely used in robot vacuums and mops, especially in budget and mid-range models.

How It Works:

The robot drags a flat microfiber pad behind it, typically mounted under a removable mopping plate. Water from a built-in tank drips onto the pad to keep it moist while it scrubs the floor.

Pros:

Affordable: Flat mop pads are inexpensive to produce and easy to replace.

Simple design: Fewer mechanical parts mean fewer chances of failure.

Quiet operation: Since there are no moving mop components, these systems are nearly silent.

Cons:

Low pressure scrubbing: These mop pads mainly rely on the robot's weight and dragging motion, which limits their ability to remove dried stains.

Uneven moisture control: Some models soak the pad too much or too little, leading to streaking or ineffective cleaning.

No active cleaning: The pad gradually becomes dirtier as it moves, meaning it could end up spreading grime rather than removing it.

Best For:

Light daily maintenance on hard floors like wood, tile, and laminate. Not ideal for sticky spills or high-traffic zones.

Dual Spin Mops

Dual Spin Mops of 3i P10 Ultra Robotic Vacuum

Dual spinning mop systems use two circular pads that rotate in opposite directions, adding active scrubbing power.

How It Works:

Mounted on a rotating platform, each mop head spins while the robot moves forward. Water from the tank wets the pads evenly, and the rotating motion mimics hand-scrubbing for better cleaning.

Pros:

Improved scrubbing performance: Spinning motion helps lift dried-on stains and grime.

Even coverage: Constant rotation keeps mop pads evenly damp and in contact with the floor.

Often self-lifting: Many models lift the mop pads when crossing carpet or returning to base, preventing cross-contamination. E.g., the dual spin mops of the 3i P10 Ultra can auto-lift 0.4 inch over carpets.

Cons:

Limited edge cleaning: Round mops can miss corners and wall edges due to their circular shape.

Requires frequent washing: Although more effective than flat mops, the pads still accumulate dirt and need regular cleaning.

Best For:

Homes with frequent spills, sticky messes, or pets. These are more effective for deeper cleaning than flat pads but still need some maintenance.

Roller Mop Systems

Real-Time Self-Cleaning Extendable Roller Mop of S10 Ultra

Roller mops are the latest innovation in robot vacuum mopping. They use a rotating cylindrical mop—often powered by a dedicated motor—that scrubs the floor while rolling.

How It Works:

The roller mop rotates against the floor as the robot moves. Unlike flat or spinning mops, the roller covers a wider surface area and maintains continuous contact. High-end models such as the 3i S10 Ultra also include systems to wash the roller in real time, ensuring it stays clean throughout the mopping session.

Pros:

Superior scrubbing pressure: Rollers can apply consistent pressure across the surface, delivering better results on stubborn dirt.

Larger coverage per pass: Cylindrical design covers more ground, reducing cleaning time.

Best for liquid spills: Roller mops absorb and remove liquids more effectively than flat or spinning pads.

Cons:

Higher cost: Roller mop robots are usually found in premium models, with more advanced engineering.

Roller maintenance: While the roller cleans better, it also needs to be washed regularly unless the system includes self-cleaning features.

Best For:

Large households, families with pets or children, and users looking for a high-performance mopping solution.

3i Real-Time Self-Cleaning Roller Mop

Comparing Types of Mop Pads

One standout in the roller mop category is the 3i S10 Ultra, which pushes cleaning technology even further by introducing a real-time self-cleaning system for its roller mop. This smart feature ensures the mop hardly spreads dirt—it always stays clean and ready for more.

How It Works:

As the 3i S10 Ultra mops your floor, it sprays a mixture of clean water and detergent through 12 precision nozzles, evenly distributing moisture across the roller mop. While the mop rotates at 330 RPM, the system actively scrubs the floor with strong 12N downward pressure, efficiently removing sticky stains, footprints, or spilled drinks.

But the innovation doesn’t stop there. Right after the mop cleans the floor, a squeegee blade presses against the roller to remove dirty water and debris. This contaminated water is then immediately vacuumed into a separate wastewater tank, preventing any reapplication of grime.

Why It Matters:

Cleaner mop, cleaner floor: Since the mop is washed in real-time, you're always cleaning with a fresh mop—not a pad already soaked with dirt.

Great for messy spills: Whether it’s milk, coffee, or muddy paw prints, the S10 Ultra handles it without smearing.

Effortless maintenance: No need to manually wash the mop pad after every cleaning. It gets itself always clean during mopping.

Summary of Key Features:

Real-time self-cleaning roller mop

12-nozzle water and detergent spray

Squeegee and suction system for dirty water removal

Rotates at 330 RPM, 12N downward pressure

10.6-inch contact length, covering a larger area

Ideal for cleaning both solids and liquids

Which Mop Pad Is Right for You?

Choosing the right mop system depends on your cleaning needs and budget:

  • Go with flat mop pads if you're looking for a basic robot vacuum with occasional light mopping capabilities.
  • Consider dual spin mops if you deal with frequent spills, pet messes, or want better scrubbing without too much added cost.
  • Invest in a roller mop system, like the 3i S10 Ultra robot vacuum and mop, if you want the most powerful, hygienic, and intelligent cleaning experience. 

The best mopping robot isn’t just about what it drags across your floor—it's about how clean that mop stays while it works. And when it comes to that, the 3i S10 Ultra is in a class of its own.

FAQ

Q: Are mop pads reusable?

A: Yes. Flat, spinning, and roller mop pads are typically machine-washable and can be reused multiple times. However, for optimal hygiene and performance, it's recommended to replace them periodically—especially if you notice lingering odors or wear.

Q: Which type of mop pad is best for sticky messes like coffee or juice spills?

A: Roller mop systems, especially those with real-time self-cleaning like the 3i S10 Ultra, are best for sticky messes. They combine scrubbing pressure, continuous cleaning, and dirty water extraction to thoroughly remove residue without smearing it around.

Q: Is it worth upgrading from a flat mop robot to a roller mop system?

A: Absolutely—if deep cleaning, hygiene, and convenience matter to you. A roller mop system with self-cleaning features like the one in the 3i S10 Ultra provides significantly better performance, less manual upkeep, and superior handling of tough messes and liquid spills.

Q: What’s the maintenance like for a roller mop robot?

A: Roller mop systems generally require less frequent manual maintenance, especially when equipped with auto-cleaning features. With the S10 Ultra, maintenance is reduced even further thanks to its advanced base station, which performs deep mop cleaning after each mopping session. It also automatically replaces the mop water using WaterRecycle™ technology—eliminating the need to manually empty the wastewater tank or refill the clean water tank. This makes it significantly more hands-free than any other robot vacuum and mop on the market.
