Holikme 4 Pack Drill Brush Attachments Set, Power Scrubber with Extend Long Attachment，Cleaning Supplies for Bathtub, Shower, Grout, Tile

I picked up the Holikme drill brush set to see if it could cut down the time I spend scrubbing the bathroom and the car’s winter floor mats. After a few weekends of use, it’s earned a permanent spot in my cleaning kit—mostly for how much labor it saves on big, grungy surfaces—though it isn’t a cure‑all for every mess.

What you get and build quality

The kit includes three nylon brushes (different sizes and shapes) and a simple extension rod. Each brush has a 1/4-inch hex shank that locks into a standard drill or impact driver. The bristles are the “yellow” variety—medium stiffness in the common color-coding world—which is a smart middle ground for bathtubs, tile, grout lines, rubber mats, and most hard bathroom surfaces.

The backing plates feel solid, and the shanks are straight enough that I didn’t have noticeable wobble when chucked directly into the drill. The extension adds reach but also a bit of flex; it’s fine for light pressure in tight spots, but if you lean hard on it, you’ll feel chatter. After several full cleaning sessions, the bristles have splayed a little (as expected), but I haven’t had shedding beyond a few stray fibers.

Setup and compatibility

Setup is plug‑and‑play: chuck the brush like you would a bit, set the drill to a low to medium speed, and go. A drill driver is easier to control than an impact driver, but both work. I recommend using the drill’s clutch to limit torque at first; it gives a gentler learning curve and reduces the chance of the brush grabbing an edge and skipping. A variable speed trigger is your friend—most of my cleaning happened well below full RPM.

A note on mess: spinning brushes fling dirty water. Keep surfaces damp (not dripping) and plan for overspray. I wore old clothes and safety glasses and kept towels on adjacent surfaces to catch splatter.

Performance in the bathroom

• Tub and shower walls: On a fiberglass tub and glazed ceramic tile, the medium bristles lifted soap scum and body oils far faster than a hand brush. I paired the large round brush with a basic bathroom cleaner, let it dwell for a couple of minutes, and ran the drill at low speed. Two slow passes equaled what would normally be 10–15 minutes of hand scrubbing. The nylon didn’t scratch or dull the surfaces in my tests, but I’d still spot-test on anything delicate or coated.
• Grout lines: The smaller round brush fits standard grout joints. It’s aggressive enough to brighten lightly dingy grout, especially after a quick pre-soak with an alkaline cleaner. For deeply stained grout, you’ll still need a stronger chemical or a dedicated whitening treatment; the brush accelerates the process but doesn’t replace chemistry.
• Around fixtures and corners: The extension rod is handy for reaching behind the faucet, under a shower valve, and around the toilet base. Expect a small amount of wobble; keeping RPMs down reduces walking and keeps splatter manageable.

Kitchen odds and ends

I tried the set on a stainless sink, stove grates, and drip pans. It excels at removing greasy film and baked-on residue that hasn’t carbonized. It’s less effective on truly burnt carbon; for that, a scraper or a stiffer red/black brush (not included) plus a soaking agent works better. On stainless, the nylon didn’t mar the finish when I moved with the grain and kept the surface lubricated.

Auto detailing

This is where the Holikme set surprised me. A pre-soak on rubber floor mats with a few minutes of dwell time, followed by the large brush at low to medium speed and a bit of dish soap, brought my mats back to a dark, even finish. My first pass without dwell didn’t do much; giving the cleaner time to work made a clear difference. On fabric upholstery, I’d use caution: the medium bristles can fuzz delicate fibers. Light pressure and a test spot are essential.

Control, ergonomics, and technique

• Speed: Low to medium RPM is the sweet spot. High speed increases splatter and can glaze the bristle tips, reducing bite.
• Pressure: Let the brush do the work. Too much force mushrooms the bristles and slows the rotation.
• Orientation: Keep the brush as perpendicular to the surface as possible. Angling concentrates wear and increases the chance of the brush grabbing edges.
• Fluids: Damp surfaces reduce friction, improve cleaning, and minimize scuffing. I got the best results by applying cleaner, letting it dwell 1–3 minutes, then brushing.

Durability and maintenance

Nylon bristles will deform if overheated. If you see steam or smell hot plastic, back off the pressure and speed. Rinse the brushes after each session and spin them in the sink to shed water. I store them bristle-side up to keep the shape. After several uses, the bristles on my most-used brush splayed modestly but retained stiffness. The extension’s set screw stayed tight with a dab of thread locker.

What could be better

• Extension rigidity: The included extension is helpful but flexes under load, which introduces chatter. For heavy work in tight spots, a more rigid extension or a shorter coupling would be welcome.
• Bristle options: The set is locked to one stiffness. That’s fine for general cleaning, but having a soft (white) brush for delicate surfaces or a stiff (red) brush for heavy grime would broaden its usefulness.
• Splatter: This is inherent to powered scrubbing, not unique to this kit. Plan your cleanup accordingly.

Value

The cost-to-time-saved ratio is excellent. You bring the drill; the kit brings speed and consistency. If you’re already using decent household cleaners, this set reduces elbow grease and shortens the scrubbing part dramatically. It won’t replace chemistry or pre-soak on tough soils, but it amplifies both.

Tips for best results

• Pre-soak. Apply cleaner and give it a couple of minutes before scrubbing.
• Start gentle. Low speed, light pressure, test spot—especially on coated tubs, lacquered finishes, or fabrics.
• Work in sections. Overlap passes and wipe dirty slurry before it dries.
• Keep it damp. A misting bottle nearby helps maintain lubrication.
• Mind edges. Lift the brush as you approach silicone joints or trim to avoid lifting sealant.

Who it’s for

• Homeowners who want faster bathroom cleaning without resorting to harsh abrasives.
• Renters who need a compact cleaning solution that leverages a drill they already own.
• DIY detailers looking to refresh rubber mats, non-delicate carpets, and trunks.

Who should look elsewhere: anyone needing ultra-gentle tools for soft upholstery or natural stone, or heavy-duty tools for carbonized kitchen messes. In those cases, soft or stiff specialty brushes (or different methods entirely) are a better fit.

The bottom line

The Holikme drill brush set turns a basic cordless drill into a practical power scrubber. It’s not flashy and it won’t solve every cleaning problem, but for soap scum, grout haze, greasy film, and rubber mats, it does exactly what it should: reduce effort and speed up the job. The medium nylon bristles strike a sensible balance between safe and effective on common household surfaces, and the extension, while a bit bendy, adds useful reach.

Recommendation: I recommend this set for anyone who already owns a drill and wants to cut their scrubbing time on bathrooms, kitchen surfaces, and car mats. It’s affordable, easy to use, and durable enough for regular household cleaning. If you need either ultra-soft or ultra-stiff bristles, you’ll want to add specialized brushes, but as a baseline kit for everyday grime, this one is a smart, time-saving addition.
