Dominate Heavy rough Ins and Tight Woodwork Framing with Cordless High-Torque Precision
Smash through stubborn structural framing bottlenecks and expedite your mechanical layouts with the Bosch GRD18V-127B26X 18V Brushless 1/2-Inch High Torque Right Angle Drill Kit. Purpose-built to handle the severe, high-resistance workloads encountered by commercial plumbers, residential electricians, and HVAC HVAC technicians, this elite structural powerhouse features a robust industrial brushless motor that cranks out an incredible 1,800 in-lbs of maximum torque. Engineered with an offset right-angle profile, it provides professional contractors with the critical mechanical leverage needed to bore massive 2-9/16 inch openings using aggressive self-feed bits, or up to 5-inch pathways using heavy-duty hole saws directly through dense laminated veneer lumber (LVL), double-thick joists, and standard structural studs.
This comprehensive trade-grade configuration is loaded with advanced electronic safety and performance safeguards to protect both the user and the workpiece. The GRD18V-127 incorporates state-of-the-art dual KickBack Control sensors, an internal acceleration monitor that immediately cuts motor current if a large bit binds or hooks a hidden nail, completely eliminating severe wrist-twisting injuries. Outfitted with a heavy-duty 1/2-inch steel keyed chuck to completely arrest bit slip and runout, this ultra-maneuverable 6.8-pound tool features an integrated LED work light matrix, 2-speed select gearbox gearing, and two next-generation EXPERT 18V 6.0 Ah high-power lithium batteries that maximize runtime under high continuous mechanical draw thresholds.
Key Features
- Severe 1,800 In-Lbs High Torque Motor: Industrial-grade brushless motor supplies raw continuous torque to chew through timber framing effortlessly.
- Dual KickBack Control Technology: Integrated sensory array instantly arrests motor momentum during a bit bind-up to minimize violent tool reactions.
- 2-Speed Performance Gearbox Selection: Low gear (0–550 RPM) delivers peak raw torque for large self-feed bits; high gear (0–1,800 RPM) optimizes fast standard drilling.
- Heavy-Duty 1/2-Inch Keyed Steel Chuck: Industrial geared jaw design guarantees maximum accessory grip security, removing bit runout under load.
- EXPERT 18V 6 Ah Battery Integration: Included premium multi-layer high-power batteries provide continuous high-amperage current delivery with specialized thermal runtime properties.

PRO-TIP: High-torque right-angle drilling shifts incredible torque loads onto your cutting accessories. When boring wide structural paths using large 2-9/16 inch self-feed timber bits, always start the tool at zero RPM directly against the lumber face before fully engaging the trigger switch toggle. Let the lead screw pull the bit teeth steadily through the grain wood face lines; forcing or bucking the tool speed manually triggers the electronic safety sensor and decreases your single-charge efficiency!

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!

Best robovac we've ever bought. Would definitely buy again.
Color: Black
I got this on sale for half-price, but knowing how well it works, I would pay full price. Why? Because this is the best of the 4 robovacs I've ever bought. Two of the others stopped working. The third still works, but less well. The advantage of this unit for us is that its filter does not get clogged with dog hair.
Different brand: Our previous vac has a roller brush that collects hair, both long hair from my girls and lots of dog hair. The slit through which the dirt and dust travels to the dust collector is too small. Eventually, it gets clogged with dog hair.
Advantages of Lefant:
* The design of this vac lets the dog hair enter the dust bin where it is effectively trapped by the air filter before it can reach the vacuum motor. This is the big win.
* It does an excellent job of mapping out the rooms. I guess that's LiDAR at work.
* You can see on the companion app where it has cleaned and how it has mapped out the rooms. It remembers.
* Its obstacle avoidance and wall mapping is excellent. It tends not to get stuck, and that's a big win, too.
* It goes back to base pretty well (twice I have had to situate it so it made contact with the charging contacts. Did it miss the target, or did the dog knock it off? It probably just missed).
* After it charges, it starts cleaning again. The dust bin capacity is big enough that we don't have to empty it every time. And since it restarts its task until it finishes, our floors are less dusty and don't fill the bin as fast.
* It's voice prompts are helpful. E.g. when it returns to base it says, "Start charging."
* Installation was simple. Plug it in. Let it charge. Download the app. Press the button to start it.
* Emptying the dust bin is simple. The bin is easy to clean in the kitchen sink. I can fit my hand into it to dry it with a paper towel. The instructions warn against washing the air filter.
* It comes with spare parts (replacement brushes and another filter).
No comment features:
* I have not used the mop function, so I cannot comment.
Disadvantages:
* The air filter has two parts: A sturdy filter and a flimsy foam rubber pre-filter. The pre-filter catches the dog hair and it is difficult to brush the hairs off this pre-filter. We easily tore the first pre-filter and we are treating the second more delicately. Clearly, the pre-filters will have to be replaced often. I don't know if replacements are available, but I found filters for computer fans that might be cut to fit for about a buck per pre-filter. So I think of these pre-filters as a disposable part and I hope to find a more sturdy replacement. Owners without dogs may not be bothered by this.
Update: Almost two months have gone by and I just love this vacuum even more. It wakes up several times a day and methodically vacuums. Then it quietly slips back to its base. This is the best appliance purchase we ever made.
Update: After 5 months, I still love this gadget. Without a doubt the best appliance I have ever purchased. And I found that I can buy replacement brushes and filters. It wakes up several times a day, remembers where it left off and dutifully motors over to that spot and restarts. We have noticed how much less dusty everything is.

'Better than sweeping every day.
Color: Black
This vacuum is… fine. It generally cleans well enough, but honestly, I kind of wish I had spent a few more dollars on a better model.
It does a decent job picking up dirt, and it’s definitely quieter than my old robot vacuum, which was loud but surprisingly effective. That old one was very basic — the kind you’d find at big box stores — and it just kept going until it bumped into something. Simple, but it got the job done.
By contrast, this one is supposed to be more advanced, with LIDAR and smarter navigation. But I’m not convinced the “upgrades” are actually improvements. It has this frustrating habit of turning right, hitting an obstacle, inching forward, then turning right again — over and over. What happened to the LIDAR? That feels less like smart mapping and more like stubborn programming.
It also gets stuck more often than my old Shark robot vacuum. And when it does get stuck, it’s more problematic. Instead of gently bumping into low objects and stopping, it tries to climb them and ends up wedged or tangled. It has even knocked over heavier items, which my older, simpler vacuum never did.
Another annoyance: if you try to help it by sweeping debris from corners into the center, it might kick crumbs away as it passes and may or may not actually circle back to clean them up. And there’s nothing more irritating than hearing “job complete” and then immediately stepping on kitty litter it somehow missed.
Overall, it’s quieter and it cleans okay — but the smarter features don’t necessarily make it better. Sometimes simple and reliable beats “advanced” and unpredictable.
