Pre-emergent herbicide, when applied at the right times of year, will control weed populations before you see them. They do this by inhibiting seeds from forming roots, thus killing them as they germinate.
Eradicating weeds when they germinate is the most efficient way to control weed populations is lawns, flower beds, and even gravel driveways and walkways. It’s time-efficient and cost-effective, saving you months of combating weeds by mowing, weed whacking, hand pulling, digging, and from using costlier products to spray out weeds.
- 25 lb. bag covers up to 4,000 sq. ft.
- 50 lb. bag covers up to 8,000 sq. ft.
- Contains 16-4-8 + Iron plus Barricade pre-emergent herbicide
- This pre-emergent contains a high amount of Nitrogen, so review the "when not to apply" exceptions below for your type of lawn.
Apply only at the recommended rate.
Use our yellow walk-behind spreader to distribute this granular product.
When to apply pre-emergent herbicide:
- Apply 16-4-8 with Barricade to established Tall Fescue lawns in late winter and early spring to feed and prevent weeds. If you've already fertilized your Tall Fescue with nitrogen, then choose 0-0-7 with pre-emergent because it doesn't contain nitrogen.
- Apply 16-4-8 with Barricade to established Bermuda and Zoysia lawns in spring during "green up" to feed and prevent weeds, usually from mid to late April.
- Apply in the morning before temperatures rise above 80 degrees; do not apply during the heat of the day.
- Apply it after one full growing season when your lawn in fully rooted in and you can no longer pull up areas of the sod, after you’ve mowed it at least three times, and after you can no longer see the seams.
When NOT to apply pre-emergent herbicide:
- When seeding new lawns: Do not apply this product or any pre-emergent herbicide if you're planning on reseeding your lawn because it will inhibit germination of that seed too. If you have applied pre-emergent, wait 3-4 months before planting seeds, depending on climate conditions.
-
When laying new sod: Do not apply pre-emergent when laying sod because it will inhibit root formation if applied too soon. Likewise, do not apply pre-emergent before laying new sod - if you have applied pre-emergent, wait 3-4 months (depending on climate conditions) before laying new sod.
- Don't apply 16-4-8 with Barricade to Tall Fescue in late spring or summer; apply it only during cool months; due to high Nitrogen, don't apply to Tall Fescue during warm months.
- Do not apply to Centipede due to the high nitrogen; choose 0-0-7 with pre-emergent instead
- Don't apply 16-4-8 with Barricade to warm-season lawns like Bermuda, Zoysia, and St. Augustine in fall when going dormant or in winter or spring before green up; due to high Nitrogen apply it only when these lawns are actively growing in late spring. Instead, apply 0-0-7 with pre-emergent in fall and winter.
-
Don't apply too soon: If you laid warm season sod in autumn, chances are it will need one full growing season (summer) to root in and fill in the seams, thus skipping the winter and spring applications. If you laid sod in the autumn, here is a general application timetable:
- Zoysia - Safe to apply after Zoysia sod is 12 months old
- St. Augustine - Safe to apply after St. Augustine sod is 12 months old
-
Centipede - Due to high nitrogen, not safe for Centipede at all
- Bermuda - Safe to apply after *Bermuda sod is 6 months old
- Tall Fescue - Safe to apply after Tall Fescue is 4 months old
*TifTuf Bermudagrass is the quickest sod to establish and beats expectations for filling in the seams. If you lay the TifTuf Bermudagrass variety late summer and it’s fully rooted in and no seams are visible, it’s safe to apply the winter application of pre-emergent herbicide.

Absolute Yes for Me
Color: Black
The kids have named our vacuum ROB. And ROB is a total Workhorse. Extremely simple setup, in my opinion. Caveat: it does not work or sync with 5g signal, but it will still work generally. In other words, it will still work the same, but will not remember floor layouts. So each time you turn it on, it is not following a learned “map”. If you’re okay with it not following that map each time, then this vacuum will take great care of your floors. In my opinion, this does not affect the functionality. The Lefant Vac is impressive. It doesn’t stop at hard flooring, either— it crosses over transition strips to low- medium pile carpet and does a great job keeping the carpet clean as well. The battery life is also impressive— going for a couple hours before returning to the charging station. I can still program it to clean at certain times, but I don’t use that option. The suction power is excellent, and it has picked up long hair fur from my ex’s German Shepherd that my upright vacuum didn’t catch. Noise level is fine. I’m not losing my mind over it at all. In fact, after a few minutes of it running, I’ve forgotten all about it until it returns to the dock. ROB is able to maneuver very well around furniture and doorways. Just make sure you don’t leave anything on the floor that you don’t want sucked up. Because it will get EVERYTHING in its way. I purchased this vacuum on sale back in November 2025 and I’m so glad I took a chance on it. Best thing I’ve ordered in a while and the price couldn’t be beat. Far superior to my old Roomba. I haven’t used the wet mop setting yet since I haven’t needed it— couldn’t tell you how well that works. The dirt canister is pretty easy to empty, but bring the whole vacuum to the garbage can to empty since it can get kind of messy the first couple times you empty it, especially depending on how much dirt it’s picked up. I bought this robot vacuum for my vinyl kitchen flooring, but once I realized it was able to do far more and had conquered my medium pile carpet just as easily, the is vacuum regularly cleans my entire downstairs flooring in one charge. Jump on this if you can. I highly recommend this vacuum

A very good product, which fulfills its purpose and even more so if bought on sale.
Color: Black
I bought the vacuum cleaner from abroad, without really knowing it or having seen it, only from the reviews I read on Amazon. The product arrived perfectly packaged, on time and in perfect condition.
The manual is simple and has clear instructions, correctly translated from Chinese to English, so it wasn't difficult to get it up and running. It came with everything the box stated: charger, cable, mop liquid container, floor mop, two sets of brushes, and a HEPA filter. This same filter has a very thin foam filter, which unfortunately broke the third time I cleaned it with a brush: this seems to be normal, and the brand should review its specifications.
It's essential to place the base in a location where the device can be easily returned and where there aren't too many clutter around it to avoid problems. Install Lefant's proprietary app, and following the step-by-step instructions makes it easy to connect to Wi-Fi and your cell phone. This allows you not only to give commands to the robot but also to schedule different cleanings, check the map the vacuum cleaner is creating, etc.
Regarding the location system, the LIDAR is really good at generating a real-time map as it scans the terrain the first time we turn it on; that's why it's essential to choose the right resting and charging location, otherwise we'll have to redo the map if we move it. As the vacuum cleaner moves, it generates this map that automatically detects the rooms, although it also has an editing system that allows it to do this, determining the cleaning order for each room, blocking off areas, etc. The map is updated with each pass the robot makes, and the phone's software is responsible for correctly "determining" some lines on it, as well as independent spaces. One detail: in my case, the vacuum cleaner thinks the space under the main bed is another room, so I can ask it to clean the entire room or just that space.
Cleaning is effective, with two effective brushes and adequate suction power for daily, non-deep cleaning. It has three power levels: a quiet one, a normal one, and a powerful one. Generally speaking, normal vacuuming is enough for an average home with the usual crumbs, dust, and pet hair. In this regard, I have a long-haired cat, and it's noticeable how time and again when the robot vacuums, I find tons of loose hair and dirt: this situation has really improved in my home. The battery life is adequate, although in a 50 square meter area, I've seen that when using the highest suction power, when it reaches 60% of the remaining battery, it decides to recharge (I don't know why or if it's a programming glitch).
If you have long-pile carpets, it's advisable to lift them off the floor and not let the vacuum cleaner pass near or over them, as the brushes get tangled in the long hair, causing it to jam and prevent it from cleaning further. Although it has a carpet mode, it's designed for hard and short-pile carpets, where it basically increases the suction power. But, again, this is a problem with long-pile carpets. Regarding this, when the vacuum cleaner gets stuck or detects a situation it can't resolve, it emits a voice alert clarifying the situation, and a notification is sent to the phone, more specifically to the dedicated app. This app is very comprehensive and allows you to view real-time and aggregated statistics on the robot's work. I must say that the Chinese to English translation is better than the Spanish one, so I recommend using it in English.
I haven't used the mop enough to comment, but from the little I've used it, it's accurate in terms of the amount of liquid and the way it's distributed. You can add some kind of cleaner, as long as it's light, not sticky, and doesn't leave residue.
In conclusion, it's a purchase I recommend, a good product that fulfills its purpose. If I could improve it, I would make it come with a larger number of spare parts or make them easier to purchase, since it doesn't have much information and when looking for them, you have to rely on other brands or models.

Keeps clean with 5 cats
Color: Black, Color: Black
I like this vacuum - a very convenient solution to the issue of 5 cats leaving their hairs all over my house. The mop feature is mostly useless though, so I can’t give it a full 5 stars.
Pros:
It's way quieter than a normal vacuum. You can have a conversation with it running in the same room & not have to raise your voice at all. It’s only slightly annoying to have it running when you’re trying to listen to music/ the TV, or make a phone call.
It fits under all the furniture I have & gets between legs of chairs without me having to lift things, move things out of the way, wrestle with a power cord, then put everything back (the reasons none of us want to have to vacuum).
The dustbin will hold a lot of dirt & cat hair before it needs emptying. It has never had to quit a cleaning session early because the dustbin is too full.
The cats like to watch it work but they haven’t bothered it/ haven’t ridden on it & it hasn’t bothered them. My one cat likes to stand vigil at his food dish & the vacuum will just clean a one-inch circumference around him without trying to bump him out of the way. (It’s quiet enough that they don’t run in terror.)
Cons:
It’s advertised as working on both 2.4 Ghz & 5 Ghz Wi-Fi, but that turns out to be a total lie when you try to set it up &, suddenly, it NEEDS to connect it to the 2.4 Ghz (which I don’t know how to do & it was the specific reason I bought THIS model instead of hundreds of others). I did try pressing random buttons on my router before returning the device & it HAS been working ever since.
I have a raised threshold one half-inch high & four inches wide between two rooms that it continually struggles to climb over. It usually spends about 5 minutes there, trying, before backing down the way it came. Maybe one time in ten it actually makes it into & cleans the other room. - You’re not supposed to pick it up & help it get there, even if you feel sorry for it.
If you have the mop attached it has no chance of climbing onto anything. That’s supposedly a “feature” but when it gets into an area between two carpets and you watch it scoot back & forth repeatedly like a sad lost animal …you kind of feel bad for it.
The “mop” is just a gravity fed water reservoir with a removable (washable) cloth attached to the bottom. It doesn’t actually “mop” anything, so much as give it a very gentle slightly damp dusting. It wouldn’t clean a single dirty footprint off of a hard floor if you ran it for 100 cycles. It would only spread a spill around if it came across one.
The mop function, honestly, is pretty useless unless you have dark hardwood floors that show dust everyday.
When it’s finished cleaning, it goes back to its charging station, which could be a problem if the charging station is kept on a wood floor or carpet with the mop reservoir full (& continuously damp). So, if you’re using the mop, you have to remember to take that attachment off soon after it’s finished cleaning (or damage your floor).

Love love love!
Color: Black
This replaced my Roborock and I was terrified about going to another brand. This Lefant robot is better than it--by far! So happy i took the leap! The performance is amazing (with 1 cat and 2 messy flight birds) - stays on top of it! Setting it up in the Lefant app and to Alexa was a snap. The charge in between scheduled cleanings is quick and lasts. Mapping and zoning is a cinch. My cat was scared of my old robot but isnt afraid of this one. It is pretty quiet! If you are debating on this one, you won't regret it.

Decent Mopping for the Price
Color: Black
I’ve been running the **Lefant LiDAR Robot Vacuum and Mop** for at least 6 months, and overall it’s a capable cleaner with smart navigation. It handles pet hair, carpets, and hard floors well, and the large 450ml visible dustbin is a nice touch — easy to check and empty without guessing.
As for the **mopping feature** specifically: it’s a basic but functional 2-in-1 mopping system with a 200ml water tank and washable mop pad. It does a respectable job on everyday light dirt, footprints, and spills on hard floors like tile or hardwood. The mop applies water evenly enough for maintenance cleaning, and you can control water flow levels through the app. It also has carpet detection that’s supposed to lift or avoid mopping rugs (which mostly works, though I still set no-mop zones for thicker carpets just in case).
That said, it’s not a deep-scrubbing powerhouse — stubborn dried-on spots or heavy messes often need a second pass or manual touch-up. It’s more of a “keep the floors looking fresher between deep cleans” type of mop rather than a full replacement for hand mopping. I tend to use the mopping mode once or twice a week on low-to-medium water settings and it leaves floors noticeably cleaner without streaks when used with a good floor cleaner solution.
The combo of strong vacuuming + basic mopping in one slim robot (great for getting under furniture) makes it convenient. Battery life is solid for most homes, and the app is straightforward for scheduling and customizing zones.
If you’re looking for an affordable LiDAR robot that vacuums well and adds convenient light mopping without breaking the bank, this Lefant model is a good pick. Just don’t expect premium-level mopping performance (like spinning pads or self-cleaning stations on higher-end brands).
Would recommend for apartments or homes with mostly hard floors and light daily dirt!
