The world of grooming has changed fast in the past few years. Many men are searching for tools that are easy, safe, and give professional results at home. If you have heard about the Lawn Mower 4.0 and Lawn Mower 5.0, you might be wondering which one is better. Both are made by Manscaped, a company known for creating quality body hair trimmers. But is the new model worth the upgrade? Let’s dive deep into every feature, difference, and user experience, so you can make a smart choice for your grooming needs.
Why Lawn Mower Trimmers Are So Popular
Most men struggle with grooming body hair. Using regular razors can cause cuts, irritation, and ingrown hairs. Electric trimmers became popular because they are safer and faster. The Lawn Mower series has become a favorite for its skin-safe design, waterproof build, and modern look. The 4.0 and 5.0 versions are both big steps forward, but the details are important.
First Look: What Are Lawn Mower 4.0 And 5.0?
The Lawn Mower 4.0 was released in early 2021 and quickly became a best-seller. It offered features like ceramic blades, wireless charging, and LED lights. In 2023, Manscaped launched the Lawn Mower 5.0 Ultra, promising even more improvements. While both are aimed at body grooming, especially below the belt, the upgrades in the 5.0 make it a strong contender.
Key Features At A Glance
Here’s a quick overview of the main features:
| Feature | Lawn Mower 4.0 | Lawn Mower 5.0 |
|---|---|---|
| Blade Material | Ceramic & Stainless Steel | Dual-Head (Trimmer + Foil Shaver) |
| Battery | Li-Ion, 90 mins | Li-Ion, 70 mins |
| Charging | Wireless, USB-C | USB-C Only |
| Waterproof | Yes (IPX7) | Yes (IPX7) |
| LED Light | Yes | Yes |
| Adjustable Guards | 2 Guards (4 Lengths) | 2 Guards (4 Lengths) |
| Motor | 7,000 RPM | 7,000 RPM |
| Special Features | Travel Lock, Wireless Charging | Dual Heads, Foil Shaver |
Design And Build Quality
When you first pick up a Lawn Mower trimmer, the feel in your hand matters. The Lawn Mower 4.0 has a matte black finish, is lightweight, and fits comfortably in the palm. It’s designed to avoid slipping, even when wet. The 5.0, while similar in size, has a more modern look, with added chrome touches and a slightly heavier feel.
Durability
Both models are made to last. The 4.0 uses ceramic blades, which stay sharp and resist rust. The 5.0 adds a dual-head design: one for trimming, one for shaving. This gives more flexibility but needs careful handling. The casing for both is tough plastic, and both are IPX7 waterproof—meaning you can safely use them in the shower.
Ergonomics
The grip shape on both models is smart. The 4.0 is a bit slimmer, making it better for smaller hands or precise trimming. The 5.0 is slightly bulkier but feels more “premium.” The button placement is easy to reach. One non-obvious insight: the 5.0’s head is wider, so it covers more area fast, but may be less precise for small spots.
Blade Technology And Performance
The blade is the heart of any trimmer. The 4.0 uses a ceramic blade with stainless steel support. This blend reduces heat and friction, helping prevent nicks and cuts. The 5.0 steps up with a dual-head system: a traditional trimmer blade plus a foil shaver for a close finish.
Cutting Power
Both models use a 7,000 RPM motor, which is strong enough for thick hair. You won’t notice much difference in power. However, the 5. 0’s foil shaver head is a game-changer for those wanting a smooth, hairless look. The 4.
0 is better for trimming to a short length, while the 5. 0 can shave nearly bald.
Blade Maintenance
Ceramic blades in the 4.0 are easy to clean and stay sharp for months. The 5.0’s foil shaver needs more regular cleaning to avoid clogging. A tip for beginners: always dry the blades after use, and oil them once a month for best performance.
Battery Life And Charging
Battery is important for convenience. The Lawn Mower 4.0 offers up to 90 minutes per charge, and you can use wireless charging or USB-C. The 5.0 has a 70-minute battery, but only uses USB-C charging.
Charging Options
Wireless charging is a perk for the 4. 0. You can drop it on the dock and it charges automatically. The 5. 0 removed this feature, focusing on USB-C only. If you travel often, USB-C is easier, but some users miss the wireless dock.
Battery Indicator
Both models have LED battery indicators. The 4. 0 blinks when low and shows charging progress. The 5. 0 uses a similar system but adds a more stylish display. Charging time for both is about 1. 5–2 hours.
Waterproof And Usage In Wet Conditions
Manscaped’s trimmers are famous for being waterproof. Both models are IPX7 rated, meaning you can use them in the shower or rinse them under water.
Shower Use
Using the trimmer in the shower is safer and less messy. Hair washes away easily. Beginners often forget: always dry the device well after wet use, especially the charging port.
Cleaning
Both trimmers can be rinsed, but the 5. 0’s foil head needs extra care. Remove the foil and clean underneath. This prevents hair buildup and keeps the shave smooth.
Adjustable Guards And Length Settings
Most users want different hair lengths for different body parts. Both models come with two adjustable guards, giving four length settings.
Guard Sizes
You can trim as short as 1mm or leave up to 10mm. This is helpful for chest, arms, legs, or groin. The guards snap on easily and stay secure during use.
Customization
The 5. 0 is slightly better for variety. The dual-head lets you switch between trimming and shaving. If you want a completely smooth finish, the foil head is best. For a natural look, stick with the guards.
Special Features: Led Light, Travel Lock, Dual Heads
Manscaped adds smart features to make grooming easier.
Led Spotlight
Both models have a built-in LED light. This helps you see fine hairs in dim places. The 5. 0’s light is a bit brighter and covers a wider area.
Travel Lock
The 4.0 has a travel lock feature: hold the button for a few seconds to lock or unlock. This prevents it from turning on by accident in your bag. The 5.0 also has a travel lock, but it’s simpler to use.
Dual-head System (5.0 Only)
This is the biggest difference. The 5. 0’s dual-head lets you trim with the standard blade, then switch to the foil shaver for a close shave. This is perfect for sensitive skin, as the foil head glides gently.
| Feature | 4.0 | 5.0 |
|---|---|---|
| LED Light | Standard | Brighter, Wider |
| Travel Lock | Yes | Yes (simpler) |
| Dual Head | No | Yes |
Real User Experiences And Reviews
Reviews give real-world insight. Users of the Lawn Mower 4.0 often praise its reliability and easy maintenance. It’s been tested by thousands and has become the “safe choice” for grooming.
4.0 Reviews
- Most users report fewer nicks and cuts compared to old razors.
- Battery lasts many sessions.
- Wireless charging is a favorite feature.
- Some find the guards tricky to attach at first.
5.0 Reviews
- The dual-head is popular for smooth results.
- Foil shaver works well for armpits and groin.

- Others find cleaning the foil head a bit complicated.
Non-obvious tip: Many users don’t realize the foil head is best for dry skin. Using it on wet skin reduces effectiveness.
Price And Value For Money
Cost is a big factor for most buyers. The Lawn Mower 4.0 usually sells for around $90. The 5.0 Ultra is priced higher, about $100–$120.
What’s Included In The Box
Both models come with:
- Trimmer
- Two guards
- Charging cable (USB-C)
- Cleaning brush
- Instructions
The 4. 0 also includes a wireless charging dock. The 5. 0 has the dual-head and foil shaver.
Is The Upgrade Worth It?
If you are happy with trimming only, the 4. 0 is still a good value. If you want a smooth, shaved finish and extra flexibility, the 5. 0 is worth the extra cost. Consider how often you groom and what finish you prefer.
Safety And Skin-friendly Design
Safety is a top reason for choosing Manscaped. Both models use SkinSafe technology to prevent cuts. The ceramic blades are gentle and do not pull hair.
Sensitive Areas
For groin and armpits, the 5. 0’s foil head is gentler. The 4. 0 is safe, but beginners should use the guards first to avoid irritation. Always move slowly and do not press too hard.
Common Mistakes
- Using trimmer on wet skin with foil head (reduces efficiency)
- Forgetting to clean blades after every use (can cause skin irritation)
- Pressing too hard (can cause red spots)
Comparing Performance: Trim Quality, Comfort, And Noise
Performance matters for daily use. Both trimmers are quiet, but the 5. 0 is slightly louder due to the dual-head motor.
Trim Quality
The 4.0 gives a neat, short trim. It does not shave bald but leaves hair at a comfortable length. The 5.0 can do both: trim and shave close.
Comfort
Both handles are easy to hold. The 5. 0’s wider head covers more skin fast, but may not fit small areas. The 4. 0 is more precise for detailed work.
Noise
Noise is about 60–65 decibels for both. The 5. 0’s foil head adds a slight buzz. For most users, both are quiet enough for private use.
Battery And Charging: Real-world Test
Battery claims are often different from real use. In a real-world test:
- 4.0 lasts about 80–85 minutes, even after months of use.
- 5.0 lasts about 60–65 minutes, especially with foil head used.
Charging time is similar, but the 4. 0’s wireless dock is more convenient. USB-C is faster, but you must remember to plug it in.
Maintenance And Cleaning Tips
Keeping your trimmer clean is important for skin health and long life.
Easy Cleaning Steps
- Remove the blade after each use.
- Rinse under warm water.
- Dry with a towel.
- Use the cleaning brush to remove stuck hair.
- Oil the blade once a month.
For the 5. 0, remove the foil head and clean underneath. Never use harsh chemicals.
Blade Replacement
Manscaped recommends changing blades every 6–12 months for best results. Replacement blades are available online.
Travel And Portability
If you travel often, a trimmer that is easy to pack and charge is important.
4.0 Pros
- Slim, lightweight
- Travel lock
- Wireless dock (leave at home)
5.0 Pros
- Strong build
- USB-C charging (use same cable as phone)
- Dual-head (more options)
Both models come with a soft travel pouch.

Which One Should You Choose?
The decision depends on your needs:
- If you want a simple, reliable trimmer for short hair, the Lawn Mower 4.0 is a great choice.
- If you want more options, including shaving smooth, the 5.0 Ultra is worth the upgrade.
Beginner insight: Many people buy the 5.0 expecting the foil head to work like a razor. It shaves close but not completely bald. For totally smooth skin, you may still need a razor after trimming.
Environmental And Sustainability Impact
Both trimmers use rechargeable batteries and long-lasting blades, reducing waste compared to disposable razors. Manscaped uses recyclable packaging and offers blade recycling. The 5. 0 uses slightly more materials due to the dual-head, but both are designed for long life.
Warranty And Customer Support
Manscaped offers a 1-year warranty on both models. Customer support is available via email and live chat. Replacement blades and parts are easy to find. In case of defects, Manscaped replaces devices quickly.
Common Buyer Mistakes
Many users make mistakes when choosing or using these trimmers:
- Buying the 5.0 without needing the foil head (wasted money)
- Not checking if wireless charging is important to them
- Using the wrong guard size
- Forgetting to clean after each use
Experience-based tip: Think about how you groom daily before buying. If you only trim, the 4.0 will do the job. If you want smooth skin for special occasions, the 5.0 is better.
Where To Buy And Authenticity
Manscaped products are sold on their official website, Amazon, and select stores. Always buy from reputable sellers to avoid fake products. For more details on Manscaped’s technology, visit the Manscaped Wikipedia page.
Frequently Asked Questions
Is The Lawn Mower 5.0 Much Better Than The 4.0?

Can I Use These Trimmers For My Face?

How Often Should I Replace The Blades?
For best performance, replace blades every 6–12 months. If you notice pulling, dullness, or skin irritation, change the blade sooner.

Yes, both are IPX7 waterproof. You can use them in the shower and rinse under water. However, always dry the device and avoid charging when wet.
What Is The Price Difference Between The Lawn Mower 4.0 And 5.0?
The 4. 0 usually costs about $90, while the 5. 0 Ultra is $100–$120. Prices can vary depending on sales and bundles.
Final Thoughts
Choosing between the Lawn Mower 4.0 and Lawn Mower 5.0 Ultra is mostly about your grooming style. If you want simple, safe, and reliable trimming, the 4.0 still stands strong.

Take time to think about your needs and daily habits before buying. With the right choice, you’ll enjoy safe, smooth grooming for years to come.
