Compare the picks

21 October 2026

How we scored them

Each kit or part is scored on performance, build, value, safety and warranty, using only what the listing publishes. The Mosxoed leads on the 21-piece count and drill-driven design; the HOKLNUSE follows on 25 ft of reach.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

Buying guide: the best chimney sweep kit for a stone chimney

Reach and rod count

Count your flue height before buying. The Mosxoed gives 20 ft with 15 nylon rods (16.1 in each); the HOKLNUSE gives 25 ft with flexible rods; the MADHOLLY rods give 18 ft from 6 fiberglass rods of 3 ft each. The MADHOLLY brush is brush-only: pair it with the MADHOLLY rods, which share the 1/4 in NPT thread. A kit that falls short of the top leaves creosote where it matters most.

Brush size and bristles

Measure the flue, not the chimney: the Mosxoed includes two 6 in (15 cm) brush heads; the HOKLNUSE includes 4 in and 6 in heads; the MADHOLLY brush is 6 in diameter by 7.87 in tall with polypropylene bristles on a double-spiral steel stem. Nylon and polypropylene bristles clean without scratching the flue surface, which matters in a stone chimney where rough walls hold creosote. The MADHOLLY brush is hard-firmness; the Mosxoed bristles are a pointed rectangular shape.

Drill-driven vs manual

The Mosxoed and HOKLNUSE attach to an electric drill for rotary cleaning: the Mosxoed rotate-lock design holds in both rotation directions. The MADHOLLY rods are manual-only: the listing states they are not suitable for drills or power tools. Drill-driven cleaning is faster on a tall flue; manual rods give more control in tight bends. Stone chimney flues are often irregular, so the flexibility of the Mosxoed nylon rods helps in narrow areas.

Kit vs parts

The Mosxoed 21-piece kit is the complete buy: 15 rods, 2 brush heads, a collection bag, a metal drill bit and tape. The HOKLNUSE is a kit with two brush heads and rods. The MADHOLLY brush and rods are sold separately: the brush has a 1/4 in male NPT thread and the rods are 1/4 in NPT, so they pair, but neither listing includes the other. Buy the pair together or buy a complete kit.

Stone chimneys need the right bristles

Rough flue walls

Stone and masonry flues have rough walls that hold creosote in every crevice. Nylon and polypropylene bristles scrub without scratching the flue surface: the Mosxoed nylon bristles and the MADHOLLY polypropylene bristles both state no-scratch cleaning. Steel bristles would clean faster but risk damage; none of the four listings uses steel bristles. Match the bristle to the flue, not the price.

Creosote and fire risk

The Mosxoed listing states its kit removes soot and creosote accumulation at the bottom of the stove, inside the chimney and on the roof, helping prevent flue fires; the HOKLNUSE listing states lint, soot and creosote buildup can cause fires. After cleaning, air enters the chimney more smoothly and the fireplace burns more fully. The MADHOLLY listing recommends cleaning at least once a year, or more often with heavy use.

Thread compatibility

The MADHOLLY brush and rods share a 1/4 in NPT thread and pair together, but both listings state they are not compatible with Midwest Hearth products: verify your rod thread type before ordering. The Mosxoed rotate-lock rods connect to each other and to the drill; the HOKLNUSE rods are flexible and interchangeable. Mixing brands is where threads strip and rods separate mid-flue.

What the kits include

The Mosxoed 21-piece kit is the most complete: 15 rods, 2 brush heads, a collection bag, a metal drill bit and tape. The HOKLNUSE kit includes the two brush heads and flexible rods. The MADHOLLY brush is brush-only and the MADHOLLY rods are rods-only: together they make a complete manual set, but bought alone each is half a tool. Check the included-components line before you buy.

Sweeping a stone chimney: technique

Work top-down or bottom-up

The Mosxoed and HOKLNUSE drill-driven rods reach 20 ft and 25 ft respectively, which suits top-down sweeping from the roof with the drill spinning the brush. The MADHOLLY rods are the shortest here: a bottom-up tool for lower flues and a short second flue. Assemble the rods section by section as you feed them: the rotate-lock Mosxoed rods connect to each other and to the drill, the HOKLNUSE flexible rods bend around offsets, and the MADHOLLY 1/4 in NPT rods thread together by hand. Keep the brush fully inside the flue while it spins: a spinning brush half-out of the flue throws soot everywhere and damages bristles on the stone lip.

Match the head to the flue

Measure the flue before ordering: the HOKLNUSE kit includes 4 in and 6 in brush heads, while the Mosxoed and MADHOLLY heads are 6 in. A head smaller than the flue leaves the corners soot-covered; a head larger than the flue wedges and stalls the drill. Stone flues are often irregular inside: pick the head that matches the narrowest point of the flue, not the widest.

Drill vs manual

Drill-driven sweeping (Mosxoed, HOKLNUSE) clears heavy creosote faster and reaches further: 20 ft and 25 ft against the shorter manual MADHOLLY reach. But the MADHOLLY rods state they are not suitable for drills or power tools, so respect that limit: a manual brush with the right 6 in head still sweeps a short straight flue clean. Drill-driven rods need a chuck-tight connection and short spinning bursts; manual rods need steady push-turn strokes.

Soot control and safety

Seal the fireplace opening with a damp sheet or tape and a shop vacuum hose before the brush goes in: chimney sweeping without soot control soots the whole room. Wear a dust mask and eye protection; stone flues shed grit as the brush works. The MADHOLLY listing recommends cleaning at least once a year, or more often with heavy use: put the season start on the calendar, not the season end, so the chimney is clean before the first cold night.

After the sweep

Inspect what the brush pulled down: glazed black creosote flakes mean the wood is burning too cool, and a third-stage glaze needs a professional. Check the stone flue liner for cracked tiles while the rods are out. Store the rods assembled or coiled: the flexible HOKLNUSE rods store coiled, the sectional Mosxoed and MADHOLLY rods store broken down, and a collection bag like the Mosxoed 21-piece kit includes keeps sooty gear out of the garage.

Frequently Asked Questions

How often should I sweep a stone chimney?

The MADHOLLY listing recommends cleaning at least once a year, or more often if you use the chimney a lot.

What brush size for my flue?

The listings here offer 4 in and 6 in heads (HOKLNUSE) or 6 in heads (Mosxoed, MADHOLLY). Measure the flue and match the head. A 6 in head suits a standard 6 in flue; the HOKLNUSE 4 in head suits smaller flues or dryer vents. The MADHOLLY brush is a 6 in diameter by 7.87 in round polypropylene brush, and both MADHOLLY pieces use 1/4 in NPT threads, so they pair with each other but not with Midwest Hearth products, per the listings.

Can I use a drill with these rods?

The Mosxoed and HOKLNUSE are drill-driven. The MADHOLLY rods state they are not suitable for drills or power tools.

Which of these states a warranty?

None of the four listings states a warranty term.
