In-Depth Review
Power and Performance: 40V MAX System
The BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo is powered by a robust 40V MAX Lithium-Ion battery, providing significant power for both the string trimmer and sweeper. This higher voltage system often translates to stronger performance and longer runtimes compared to lower voltage models, making it suitable for tackling denser weeds and clearing more substantial debris. Users can expect efficient operation for typical residential yard work, ensuring tasks are completed without frequent power interruptions.
Trimming Efficiency: POWER DRIVE Transmission and AFS
The LST140 string trimmer component features a POWER DRIVE high-torque transmission. This technology is designed to deliver consistent cutting power directly to the string, facilitating clean and fast cuts through tough grass and weeds. Coupled with the Automatic Feed Spool (AFS) system, users benefit from continuous trimming without the need to manually bump the head, enhancing productivity and ease of use during extended trimming sessions around fences, trees, and garden beds.
Sweeper Capability: Air Speed and Low Noise
The LSW40 sweeper is engineered to clear hard surfaces effectively, boasting a wind speed of up to 130 MPH. This capability is ideal for moving leaves, grass clippings, and other light debris from driveways, patios, and sidewalks. A notable feature is its low noise design, which allows for quieter operation. This is particularly beneficial for users in residential areas where noise levels are a concern, offering a more pleasant experience for both the operator and neighbors. For precise edging, you might also consider WORX WG896 Electric Lawn Edger, 12 Amp 7.5″ Review 2026.
User Convenience: Battery Indicator and Warranty
Both the string trimmer and sweeper in this combo kit include a ‘state of charge’ indicator, which is a practical feature for monitoring battery levels and planning work accordingly. This helps prevent unexpected power loss in the middle of a task. Furthermore, the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo comes with a 2-year limited warranty, providing peace of mind and manufacturer support for potential issues.

Head-to-Head: How Does It Stack Up?
When comparing the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo against the Houselife 12″ Cordless Weed Eater & Leaf Blower Combo, the BLACK+DECKER model offers a complete package with a 40V MAX battery and charger included, whereas the Houselife unit is a bare tool requiring a separate Dewalt 20V battery. The BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo has a higher voltage system, which generally translates to more power for demanding tasks, while the Houselife boasts a higher CFM (650 CFM) for its blower, potentially offering stronger clearing power for some debris. Users seeking an immediate, ready-to-use system with strong performance from a single brand should opt for the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo, while those with existing Dewalt 20V batteries and a need for a very powerful blower might prefer the Houselife for cost-effective expansion of their tool ecosystem.
Against its same-brand alternative, the BLACK+DECKER LCC222 20V MAX String Trimmer and Blower Combo, the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo stands out with its 40V MAX power system, providing twice the voltage for potentially greater cutting and blowing force. The LCC222, however, includes two 20V batteries, offering extended runtime through swapping, and features a lighter trimmer at 4.5 lbs compared to the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo’s unspecified but likely heavier 40V trimmer. If you prioritize maximum power and efficiency for tougher jobs, the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo is the stronger choice. If lighter weight, dual batteries for longer work sessions, and a slightly lower power output are acceptable for smaller yards, the LCC222 might be more suitable.

Compared to the WORX WG928 20V 12″ Cordless String Trimmer & Blower Combo, the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo offers a higher 40V MAX power system, which typically provides more torque and sustained power than WORX’s 20V system. The WORX WG928 includes two 20V batteries, similar to the LCC222, which can be advantageous for extending runtime. While the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo’s sweeper matches the WORX’s 130 MPH wind speed, the WORX blower has a higher CFM at 360 compared to the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo’s implicit CFM. The WORX also features a convenient push-button line feed system. The BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo is better for users seeking higher overall power from a single battery system, while the WORX WG928 is a strong contender for those who value dual batteries for extended work and a slightly higher CFM blower, along with the convenience of the PowerShare battery system.
Is It Right for You?
Best For
- Homeowners with medium-sized yards needing a powerful, all-in-one cordless solution.

Final Verdict
The BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo offers a compelling package for efficient yard maintenance. Its 40V MAX system, coupled with the POWER DRIVE high-torque transmission and Automatic Feed Spool, ensures effective trimming and edging. The sweeper component delivers a robust 130 MPH wind speed for clearing debris, all while maintaining a low noise profile. This combo positions itself as a mid-range to premium option for users seeking reliable cordless performance.
While the single 40V battery provides ample power, it might limit very extended use for larger properties without a spare. Some users might find its weight slightly higher than lighter 20V alternatives, a common trade-off for increased power and runtime. However, the convenience of having both tools share a common battery platform, along with the included charger, makes it a practical choice.
Ultimately, the BLACK+DECKER LCC340C Cordless Trimmer Sweeper Combo is an excellent choice for homeowners with medium-sized yards who need a powerful, convenient, and relatively quiet solution for trimming, edging, and sweeping. Its robust performance and user-friendly features make it a strong contender against other cordless combos, particularly for those seeking a complete system ready to use out of the box.

This bare-tool set includes a 12-inch string trimmer and a handheld leaf blower, both powered by your existing Dewalt battery (not included). Weighing just 7.2 pounds total, the combo is exceptionally lightweight and easy to maneuver, making it ideal for small to medium-sized lawns, seniors, or anyone seeking a fatigue-free experience.

Overall, the Houselife combo offers excellent value for Dewalt users seeking an affordable, lightweight, and versatile yard maintenance set. Its thoughtful design and solid performance make it a reliable choice for routine trimming and cleanup.

The BLACK+DECKER LCC340C 40V Max Cordless Sweeper & String Trimmer Combo Kit is a versatile yard care solution for homeowners with small to medium properties.

The build quality is solid for its price point, with a lightweight design (11 lbs) that reduces fatigue. The low noise operation is a welcome feature for residential areas. However, some users note that the blower's speed may not consistently reach the advertised 130 MPH, and the continuous hold button can cause finger discomfort during extended use. Battery life may be a limitation for larger yards, but an extra battery can extend runtime.
Overall, the BLACK+DECKER LCC340C offers excellent value for its combination of power, convenience, and ease of use. It is best suited for small to medium yards where cordless freedom and low maintenance are priorities.
Pros
- Excellent value with two tools and two batteries included
- Lightweight and easy to maneuver for extended use

The BLACK+DECKER LCC222 20V MAX String Trimmer and Blower Combo is a versatile, cordless yard maintenance solution designed for homeowners with small to medium-sized properties. This kit includes a string trimmer that can also function as an edger, plus a hard surface leaf blower, all powered by two included 20V MAX lithium-ion batteries and a charger.
One of the standout features is the automatic feed system (AFS) that supplies trimmer line as needed without the usual bumping required, making trimming uninterrupted and efficient. The trimmer head rotates 180 degrees to convert from trimming to edging along sidewalks and driveways, adding to its versatility. Both the trimmer and blower are lightweight (4.5 lbs and 3.7 lbs respectively), reducing fatigue during extended use.
The batteries hold their charge for up to 18 months, ensuring the tools are ready when needed. However, users report that the blower is not powerful enough for heavy leaf piles, and the trimmer line is thin and short, making it best suited for light-duty tasks like maintaining grass around flower beds and fences. Battery life is approximately 30 minutes per charge, which is acceptable for small yards but may require swapping batteries for larger areas.
Overall, this combo kit offers excellent value for the price, providing two essential tools and two batteries at a competitive cost. It is ideal for homeowners seeking a convenient, low-maintenance alternative to gas-powered equipment, especially those with smaller yards who prioritize ease of use and quiet operation.
Pros
- Lightweight and easy to handle for extended use
- Convenient 2-in-1 trimmer/edger conversion
- Command Feed line system reduces downtime
- Surprisingly effective blower for dry leaves and debris
- Great value for money compared to gas alternatives
Cons

- Charger is slow, taking several hours to recharge
- Not ideal for tall or thick grass; lacks power for heavy-duty jobs
The WORX WG928 20V PowerShare string trimmer and leaf blower combo kit is a practical, battery-powered solution for homeowners who need essential lawn care tools without the hassle of gas engines. This kit includes a 12-inch cordless string trimmer that also functions as an edger and a 360 CFM turbine blower, making it easy to trim grass, edge walkways, and clear debris after mowing. Designed for small to medium-sized yards, it offers a lightweight and quiet alternative to traditional gas-powered equipment.
The standout feature of this combo is the 2-in-1 trimmer/edger. By simply pivoting the head, you can switch from trimming grass around fences and flower beds to edging along sidewalks and driveways. The Command Feed system lets you advance the trimmer line with a push button, so you don't have to bump the head to get more line. The blower delivers up to 360 CFM at 75 MPH, which is surprisingly effective for clearing dry leaves, grass clippings, and dust from patios, decks, and driveways. Both tools are lightweight, with the entire kit weighing just 10.4 pounds, making them easy to carry and maneuver for extended periods.
Build quality is solid for the price point, with durable plastic housings and an orange and black color scheme that matches other WORX tools. The PowerShare battery system is a major plus, as the same 20V batteries work across a wide range of WORX tools and can be combined for higher voltage needs. The kit comes with two 2.0Ah batteries and a charger, which provide enough runtime for typical small yard tasks, but users with larger properties may find they need to swap batteries mid-job.
One common drawback is the slow charger, which can take several hours to fully recharge a depleted battery. Some users also report that the trimmer struggles with thick or overgrown grass, so it is best suited for regular maintenance rather than heavy-duty clearing. Additionally, the included batteries are only 2.0Ah, so buying larger capacity batteries or an extra set is recommended for uninterrupted work.
Overall, the WORX WG928 combo is an excellent value for homeowners seeking a convenient, low-maintenance, and cordless lawn care solution. It is especially well-suited for older users or anyone who wants to avoid the noise, fumes, and maintenance of gas tools. It consistently earns praise for its ease of use, lightweight design, and reliable performance for routine yard upkeep.
Pros

- Good blowing power for driveways and patios
- Battery compatibility with other GOODJOB tools
- Quick assembly and simple operation
- Affordable price point for a combo kit

This kit includes a 12-inch cordless string trimmer and a handheld leaf blower that share the same 20V battery platform, making it easy to switch between trimming edges and clearing debris.
The standout feature is the ultra-lightweight trimmer, weighing only 3.5 lbs. This makes it comfortable for extended use, especially around fences and flower beds. The auto-feed spool ensures the line advances smoothly, so you don't have to stop and bump the head. The leaf blower delivers 650 CFM at 200 MPH, which is sufficient for clearing dry leaves and grass clippings from hard surfaces like driveways and patios.
Build quality is decent for the price point, with plastic construction that keeps weight down. The kit includes two 2.0Ah batteries and a fast charger, allowing you to swap batteries and keep working. Battery life is adequate for small jobs, but some users report that it drains quickly when the blower is on the highest setting or when tackling thicker weeds.
On the downside, a few users have experienced issues with the string not extending properly, and the blower's runtime is limited for larger properties. The trimmer is best suited for light to moderate trimming, not heavy brush. Overall, this combo is a great value for those with a small yard or for quick touch-ups between professional services.
Verdict: If you need an affordable, lightweight, and easy-to-use trimmer and blower combo for routine maintenance, the GOODJOB 20V kit is a solid choice. Just be aware of the battery limitations for bigger tasks.
