If you want the longest cable in this comparison and a written warranty, the Milwaukee 2772A-21 kit runs 35 ft of 5/16 in cable and carries a 5-year tool warranty with 2 years on the cable.

[The verdict](#the-verdict) 16. [FAQ](#faq) ## The specification that actually decides this Most cordless drain cleaner guides compare voltage. Voltage is not what decides it. Two numbers matter more, and they sit in different rows of the spec sheet: the cable length and the pipe diameter range the auger is rated to clean. Cable length tells you how far past the drain opening the cutter can reach. In this set, that number ranges from a small handheld Populo 12V unit with no listed cable length to the Milwaukee 2772A-21 at 35 ft. A shower stoppage sitting in the P-trap needs about 3 ft of reach. A kitchen line clogged where it joins the branch may need 15 ft. A main line clog needs 25 ft or more, which cuts the field sharply. Pipe diameter is the second gate. The Ridgid Power Spin+ tops out at 1-1/2 in, which covers a bathroom sink and a shower but not a kitchen line or a 3 in cleanout. The K KORKUAN and Milwaukee both quote 3 in as the ceiling. Everything else falls between. Voltage matters only after those two constraints are met. A 12V unit with enough reach and pipe range clears a soft hair clog just as well as a 20V unit for that job. What voltage buys is torque for cutting, not distance and not pipe fit. ## Best cordless drain cleaner at a glance | Pick | Cable and pipe range | Battery platform | Price | | ------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------- | -------------------------------- | ---------------------------------------------------------------- | | **Best overall**[K KORKUAN Cordless Electric Drain Auger](https://www.amazon.com/dp/B0H94TM5RG?tag=ijcci-20) | 23.62 ft cable3/4 to 3 in pipe | Milwaukee 18V (bare tool) | [Check Price](https://www.amazon.com/dp/B0H94TM5RG?tag=ijcci-20) | | **Best premium**[Milwaukee 2772A-21 Drain Snake Kit](https://www.amazon.com/dp/B07814DJ12?tag=ijcci-20) | 35 ft, 5/16 in cable1-1/4 to 3 in pipe | Milwaukee 18V (kit) | [Check Price](https://www.amazon.com/dp/B07814DJ12?tag=ijcci-20) | | **Runner-up**[Ublue 21V Cordless Drain Auger](https://www.amazon.com/dp/B0H1CFXDYW?tag=ijcci-20) | 25 ft cable3/4 to 2.95 in pipe | Ublue 21V, 2.0Ah included | [Check Price](https://www.amazon.com/dp/B0H1CFXDYW?tag=ijcci-20) | | **Best for beginners**[POPULO 20V Cordless Drain Auger](https://www.amazon.com/dp/B07MTCZ61R?tag=ijcci-20) | 25 ft, 1/4 in cable3/4 to 2 in pipe | Populo 20V, 2.0Ah included | [Check Price](https://www.amazon.com/dp/B07MTCZ61R?tag=ijcci-20) | | **Best for heavy use**[SKIL PWR CORE Power Snake Kit](https://www.amazon.com/dp/B0CL9J2C33?tag=ijcci-20) | 25 ft, 1/4 in cable3/4 to 2 in pipe | SKIL PWR CORE 20, 2.0Ah included | [Check Price](https://www.amazon.com/dp/B0CL9J2C33?tag=ijcci-20) | | **Best for pros**[POPULO 12V Handheld Drain Snake](https://www.amazon.com/dp/B0FX9LBXGB?tag=ijcci-20) | Cable length not listed3/4 to 2 in pipe, soft clogs only | Populo 12V, integrated | [Check Price](https://www.amazon.com/dp/B0FX9LBXGB?tag=ijcci-20) | | **Best budget pick**[Ridgid Power Spin+ Drain Cleaner](https://www.amazon.com/dp/B079Q2Q3TT?tag=ijcci-20) | Drill-powered, up to 500 rpm3/4 to 1-1/2 in pipe | Uses your own drill | [Check Price](https://www.amazon.com/dp/B079Q2Q3TT?tag=ijcci-20) | ## How the picks were screened I started with the seven listings in the input and lined up their published specifications side by side: cable length, pipe diameter, weight, dimensions, warranty and battery platform. Two figures did the most work in ranking them. The first was pipe range. Anything that could not clear a 2 in line dropped down the order, because a 2 in ceiling excludes most kitchen branches and any 3 in cleanout. That knocked the Ridgid Power Spin+ to a budget slot, since its 1-1/2 in ceiling is a real constraint even though the tool is well-made in other ways. The second was cable length. Two of the picks push past 25 ft: the Milwaukee 2772A-21 at 35 ft and the K KORKUAN at 23.62 ft. Both handle 3 in lines. That combination is rare in this set, so both climbed. Battery platform then split the top of the field. The Milwaukee kit is closed: an M18 battery and charger travel with the tool. The K KORKUAN takes the same M18 battery but ships as a bare tool. If you already own the battery, the K KORKUAN saves you the cost of a second one. If you do not, the Milwaukee kit is the one you can open and use the same afternoon. That trade-off decided first place: the K KORKUAN wins on flexibility, the Milwaukee wins on the longer cable and the printed warranty. ## 1\. K KORKUAN Cordless Electric Drain Auger — Best overall **A 23.62 ft replaceable cable, a 3 in pipe ceiling and Milwaukee M18 compatibility make this the most flexible pick if you already own the battery.** [![K KORKUAN 18V cordless drain auger in red — the 3 in pipe ceiling and M18 compatibility that anchor its overall win](https://m.media-amazon.com/images/I/41XEQh9BvJL._SL500_.jpg)](https://www.amazon.com/dp/B0H94TM5RG?tag=ijcci-20) **Best for:** owners of Milwaukee 18V batteries who want a longer, replaceable cable **Skip it if:** you do not already own an M18 battery or charger Two features tip this into first place inside the set. The steel cable runs 23.62 ft and is fully replaceable, according to K KORKUAN, so a kinked or broken cable does not end the tool. And the auger is rated for 3/4 to 3 in pipes, which is the wider range shared only with the Milwaukee 2772A-21 here. Variable speed runs from 0 to 550 rpm on the trigger, giving you a slow start into a P-trap and full speed for cutting. The listing calls out a built-in LED for dark under-sink work and a water outlet for flushing the cable while it runs. The body weighs 8.16 lb with the battery attached, roughly the same as the SKIL kit and lighter than the Populo 20V. The catch is real. This is a bare tool, so a battery and charger are separate. If your garage already runs on M18, that is a saving. If not, factor the platform buy in before choosing. **Pros:** - 3/4 to 3 in pipe range, widest tier in this set - 23.62 ft replaceable steel cable - Variable speed 0 to 550 rpm - Built-in LED and drain port for flushing - Runs on Milwaukee M18 batteries you may already own **Cons:** - Sold as a bare tool: no battery or charger in the box - Only one seller lists it on Amazon - No published warranty on the listing [Check Price on Amazon](https://www.amazon.com/dp/B0H94TM5RG?tag=ijcci-20) ## 2\. Milwaukee 2772A-21 18V Cordless Drain Snake Kit — Best premium **The 35 ft cable, the enclosed drum and a printed 5-year tool warranty make this the pick when the clog might sit deep in the line.** [![Milwaukee 2772A-21 cordless drain snake kit — the 35 ft cable and enclosed drum that define its premium slot](https://m.media-amazon.com/images/I/31o9rH22GeL._SL500_.jpg)](https://www.amazon.com/dp/B07814DJ12?tag=ijcci-20) **Best for:** buyers who want the longest cable in this set and a written warranty **Skip it if:** you rarely face clogs past a bathroom P-trap This is the most expensive pick here, and the specification sheet earns most of it. The cable measures 5/16 in by 35 ft, the longest reach in the comparison by more than 11 ft. Pipe range runs from 1-1/4 to 3 in, which covers everything from a kitchen branch to a 3 in floor drain. Milwaukee calls this the only handheld auger with a fully enclosed drum, and the CABLE-DRIVE system feeds and retracts the cable rather than leaving you to push it in by hand. The warranty is the other lever. Milwaukee publishes 5 years on the tool and 2 years on the cable, the only stated warranty in this set apart from the Ridgid budget pick. The kit ships with an M18 battery and charger, so it opens and runs. The trade-off is size and starting cost. At 8.2 lb and 20.5 in long, this is not a tool you leave in a kitchen drawer, and the price position sits at the top of the set. For a bathroom-only user, that is money spent on reach you never use. **Pros:** - 35 ft cable, the longest here - 5-year tool warranty, 2-year cable warranty - Fully enclosed drum reduces mess - Ships as a kit with M18 battery and charger - Handles 3 in pipes **Cons:** - Highest price position in the set - Bulkier than a handheld auger at 20.5 in long - 5/16 in cable is thicker than 1/4 in options, less suited to tight bathroom traps [Check Price on Amazon](https://www.amazon.com/dp/B07814DJ12?tag=ijcci-20) ## 3\. Ublue 21V Cordless Electric Drain Auger — Runner-up **A 25 ft cable, a stated 2.95 in pipe ceiling and an included 2.0Ah battery, at an entry price position.** [![Ublue 21V cordless drain auger in green with included bag and gloves — the 25 ft cable and 2.95 in ceiling that lift it above the entry tier](https://m.media-amazon.com/images/I/41T5b0B1q3L._SL500_.jpg)](https://www.amazon.com/dp/B0H1CFXDYW?tag=ijcci-20) **Best for:** shoppers who want an included battery and a 25 ft cable at an entry price **Skip it if:** you need to clear a line wider than 2.95 in The Ublue reads as the value pick of the set. Ublue quotes a 25 ft auto-feed cable and a pipe range from 3/4 to 2.95 in, which is close to the 3 in ceiling on the top two picks. The listing describes 610 variable speed control and an auto-feed system, so the cable drives forward and back on a trigger rather than a hand crank. The kit includes the 2.0Ah battery, a bag, gloves and a rag. That matters because the two most-flexible tools in this set, the K KORKUAN and one Populo model, do not include a battery in the box. The Ublue arrives ready to run. The gap between it and the winners is the ecosystem. Ublue's 21V battery does not fit another tool in your garage. The K KORKUAN and Milwaukee both plug into M18, which many households already run. If this is your only cordless tool, the Ublue is a fine standalone buy. If you already own a platform, it becomes a second charger to keep track of. **Pros:** - 25 ft auto-feed cable - 3/4 to 2.95 in pipe range, near the top of the set - 2.0Ah battery, bag and gloves included - Auto-feed instead of hand-cranking - Entry price position **Cons:** - 21V battery is a standalone platform, not shared with other tools - No published warranty on the listing - Weight not listed, so hard to compare handling [Check Price on Amazon](https://www.amazon.com/dp/B0H1CFXDYW?tag=ijcci-20) ## 4\. POPULO 20V Cordless Electric Drain Auger — Best for beginners **A 25 ft, 1/4 in cable and a full kit make this the easiest cordless drain cleaner in the set to pick up and use without a plumber's habits.** [![POPULO 20V cordless drain snake with replaceable cable — the beginner-friendly 25 ft cable and full kit contents](https://m.media-amazon.com/images/I/51R9maTVEUL._SL500_.jpg)](https://www.amazon.com/dp/B07MTCZ61R?tag=ijcci-20) **Best for:** first-time users clearing kitchen and bathroom drains at 2 in or under **Skip it if:** you need to reach past 25 ft or into a 3 in line This Populo model gets the beginner slot for three reasons. The kit is complete: 25 ft of 1/4 in cable, a 2.0Ah battery, a charger, a storage bag and gloves all in one box. The cable is replaceable, so the first accidental kink is not a tool-ending event. And the pipe range, 3/4 to 2 in, matches the drains most households actually deal with: kitchen sinks, bathtubs, showers and utility lines. The listing describes an auto-feed system and a rubberised grip handle for one-handed use. Weight is 10.8 lb, the heaviest in this comparison, which is worth knowing if you clear drains from a squat or under a sink cabinet. Where it sits in the ranking is worth explaining. The 2 in ceiling is real; the Ublue reaches 2.95 in and both winners reach 3 in, so this Populo is not the tool for a 3 in cleanout. But for anyone who has never run a powered auger before, the trade-off is fair. This one buyers reach for most often in the set, and the kit is complete out of the box. **Pros:** - Complete kit including battery, charger, bag and gloves - 25 ft replaceable 1/4 in cable - Auto-feed for hands-free cable drive - The one buyers choose most often here - Ergonomic grip for one-handed use **Cons:** - 2 in pipe ceiling limits kitchen branches at 3 in - Heaviest tool in the set at 10.8 lb - 20V Populo platform is not shared widely [Check Price on Amazon](https://www.amazon.com/dp/B07MTCZ61R?tag=ijcci-20) ## 5\. SKIL PWR CORE 12/20V Cordless Power Snake — Best for heavy use **A 25 ft carbon steel cable and a 20V battery from a wider PWR CORE platform, for households already in SKIL's ecosystem.** [![SKIL PWR CORE 20V cordless power snake drain cleaner — the 1/4 in carbon steel cable and platform integration that suit repeat use](https://m.media-amazon.com/images/I/31IO5r5L1FL._SL500_.jpg)](https://www.amazon.com/dp/B0CL9J2C33?tag=ijcci-20) **Best for:** households already in the SKIL PWR CORE 20 battery system **Skip it if:** you want the longest cable or a stated warranty The SKIL sits in a specific slot: buyers already invested in PWR CORE 20 tools. The kit ships with a 20V 2.0Ah battery and a 30W charger, so the drain cleaner joins a family of tools that share the same battery. That matters if this is your fifth SKIL tool. It does not if it is your first. The specification sheet is solid across the middle. The cable is 1/4 in by 25 ft in carbon steel, and pipe range is 3/4 to 2 in. SKIL describes an auto-feed clutch that extends and retracts the cable, and a variable speed trigger for control. Weight is 7.54 lb, the lightest tool in the powered set. What stops it climbing higher is the missing 3 in ceiling and the absence of a printed warranty on the listing. The Milwaukee kit gives you both. The K KORKUAN gives you the 3 in ceiling on a battery many homes already own. If neither ecosystem is yours and SKIL is, this is the natural pick. **Pros:** - 25 ft, 1/4 in carbon steel cable - Lightest powered tool in the set at 7.54 lb - Variable speed trigger and auto-feed clutch - Shares batteries with other PWR CORE 20 tools - Full kit with battery and charger **Cons:** - 2 in pipe ceiling - Slowest seller of the set on the current data - No stated warranty on the listing [Check Price on Amazon](https://www.amazon.com/dp/B0CL9J2C33?tag=ijcci-20) ## 6\. POPULO 12V Cordless Handheld Electric Drain Snake — Best for pros **A handheld 12V auger built specifically for soft clogs in 3/4 to 2 in indoor lines, so a plumber can clear a hair or grease job in a minute.** [![POPULO 12V cordless handheld drain snake auger — the compact one-handed shape that suits quick service calls](https://m.media-amazon.com/images/I/41j8OsN78PL._SL500_.jpg)](https://www.amazon.com/dp/B0FX9LBXGB?tag=ijcci-20) **Best for:** plumbers making quick calls on soft clogs in 3/4 to 2 in indoor lines **Skip it if:** you might be tempted to run it into a toilet or a hard blockage This handheld earns the pro slot because Populo has been unusually specific about what it is for. The listing states, in plain words, that the tool is for grease, hair or paper towels in 3/4 to 2 in indoor lines, and not for hard objects or toilets. That kind of clarity is rare in a category where every listing implies it clears anything. The 12V battery is integrated. There is no separate battery to charge or lose. The auto-feed drives the cable forward and back on a switch, and the flexible steel shaft is shaped to move through P-traps. For a pro who runs a dozen jobs a week, the appeal is speed at the door: pull it out, clear the trap, put it back. No corded cable, no bulky drum. The trade-off shows in what the listing does not publish. Cable length is not stated on the input. Weight and full dimensions are not stated. For a first-time buyer that is a lot of missing information; for a plumber who has handled one before, the shape and the pipe range are enough. **Pros:** - 12V handheld shape for one-handed use - Integrated battery, no separate pack to track - Auto-feed switch drives cable in and out - Populo names the exact soft-clog use case - Entry price position **Cons:** - Cable length and weight not published - Explicitly not for toilets or hard objects - No published warranty - Only one seller lists it [Check Price on Amazon](https://www.amazon.com/dp/B0FX9LBXGB?tag=ijcci-20) ## 7\. Ridgid 57043 POWER SPIN+ Drain Cleaner — Best budget pick **A hand-cranked or drill-driven spinner for 3/4 to 1-1/2 in lines, backed by a lifetime warranty against material defects.** [![Ridgid POWER SPIN+ drain cleaner with autofeed trigger — the compact bathroom-line tool with a lifetime defect warranty](https://m.media-amazon.com/images/I/31jYbP0PWPL._SL500_.jpg)](https://www.amazon.com/dp/B079Q2Q3TT?tag=ijcci-20) **Best for:** one-drain households with a slow bathroom sink or shower **Skip it if:** you need to clear anything wider than 1.5 in The Ridgid is not a battery tool at all. It is the cheapest pick here, and it works either as a hand-cranked spinner or attached to a drill up to 500 rpm. That is the honest reason it wins the budget slot: it costs nothing to power beyond a drill you likely already own, and Ridgid backs it with a lifetime warranty against material or workmanship defects. No other pick in this set matches that warranty terms. The MAXCORE cable is kink-resistant, and the AUTOFEED trigger drives the cable down the drain. Ridgid says the cable is positively retained in the drum to stop pullout. The whole unit weighs 5.47 lb, the lightest here by a comfortable margin. The ceiling is where the pick ends. Pipe range is 3/4 to 1-1/2 in only, so a kitchen branch at 2 in or a floor drain at 3 in is out of scope. This is a bathroom tool, sold with clarity as one. Category note: Amazon files this under demolition drills rather than drain augers, which is a listing quirk, not a product one. **Pros:** - Lightest pick at 5.47 lb - Lifetime warranty against defects - Works with a drill up to 500 rpm or by hand - AUTOFEED trigger and drum retention - Cheapest of the seven **Cons:** - 1-1/2 in pipe ceiling excludes most kitchen lines - Not a self-powered cordless tool: needs your drill - Filed in a hammer drill category, which can confuse search [Check Price on Amazon](https://www.amazon.com/dp/B079Q2Q3TT?tag=ijcci-20) ## What kind of clog are you actually facing? Match the drain to the tool before the specification sheet. Four categories cover most home jobs. - **Hair in a bathroom drain:** 3/4 to 1-1/2 in line, soft clog, sits within a foot or two of the drain. Almost any pick in this set clears it. The Ridgid Power Spin+ is the honest match. - **Kitchen sink slowing down:** usually a 1-1/2 to 2 in line, grease-based, may sit further from the drain than a hair clog. You want at least 15 ft of cable and a 2 in pipe rating. The Populo 20V, the SKIL and the Ublue fit. - **Shower or tub filling up:** typically a 2 in line, hair-based, past the P-trap. Same tool class as the kitchen job. - **Floor drain or utility line at 3 in:** only the K KORKUAN and the Milwaukee 2772A-21 are rated to that ceiling in this set. If you do not know which type you have, work from the smallest tool first. A hair clog in a shower does not need 35 ft of Milwaukee cable, and running a heavy auger into a 1-1/2 in line risks the trap fitting more than the clog does. ## Bare tool or kit: which saves you money? Two of the seven picks ship as bare tools: the K KORKUAN and the handheld Populo 12V. Five ship as kits with the battery and charger included. The right answer depends entirely on what is already on your garage shelf. Here is the pattern that decides it: 1. If you already own a Milwaukee M18 battery, the K KORKUAN is the cheapest way into a 3 in pipe rating. You pay for the tool, not the battery. 2. If you own no cordless platform yet, buy a kit. The Populo 20V, the Ublue and the SKIL all ship complete, and starting a new platform mid-clog is not the moment to discover a battery is not included. 3. If you already own SKIL PWR CORE 20 tools, the SKIL kit is the natural add: the same battery drives more tools you own. 4. If you own no platform and want the widest capability, the Milwaukee 2772A-21 kit is the one-buy answer. It arrives ready, and the battery joins the wider M18 family later. The bare-tool trap is buying one because it looks cheaper, then finding out the M18 battery costs as much as the tool. Check the sticker on your current cordless drill before you order. ## How far will 25 feet of cable really reach? Cable length on the listing is not the same as reach past the drain opening. Some of the cable stays in the drum. Some winds through the auto-feed. And every bend in the line trades length for direction change. A useful working figure: expect to lose 2 to 3 ft to the drum and feed mechanism, and another foot per tight bend. On a 25 ft rated cable, that means 20 to 22 ft of usable reach through a typical two-bend residential line. The Milwaukee 2772A-21 at 35 ft gives you real 30 ft reach on a similar path, which is what pushes it into main-line and cleanout work. The K KORKUAN and Ublue both quote replaceable cables. That is more important than it sounds. A cable kinks when you push it against a bend at full speed. On a fixed-cable tool, that ends the auger. On a replaceable-cable tool, you order a new cable and keep the motor. If you plan to run the tool more than twice a year, replaceable is the safer buy. ## What the listings do not tell you Four gaps recur across the input, and each one is worth watching for. - **Noise.** None of the listings publishes a decibel figure. A cordless auger at 550 rpm inside a kitchen cabinet is loud, and that matters for shared walls and pets. - **Torque under load.** Voltage is on every listing; measured torque is on none. A 20V tool with a bad gearbox loses to a 12V tool with a good one. Trust the pipe range and cable spec, not the voltage. - **Battery runtime per clog.** Even the kits that publish 2.0Ah do not state how many drains that clears. Plan for a spare battery on the same platform if you clear more than one drain a session. - **Repair parts.** Only two picks state the cable is replaceable. For the rest, a kinked cable is a tool replacement, and the listings do not tell you either way. None of this makes any pick a bad choice. It sets expectations. Read the listing for what it says, and read this list for what it does not. ## The verdict If you already own a Milwaukee M18 battery, buy the K KORKUAN. You get a 23.62 ft replaceable cable, a 3 in pipe ceiling and variable speed to 550 rpm, at a price that reflects the missing battery. That is the best value in the set once the platform is accounted for. If you own no battery platform and want a tool that handles the widest range of jobs the day it arrives, buy the Milwaukee 2772A-21 kit. The 35 ft cable is the longest here, the enclosed drum reduces splash back, and Milwaukee's 5-year tool and 2-year cable warranty is the only stated warranty in this set apart from the Ridgid budget pick. The premium price position buys reach and support you cannot get elsewhere in this comparison. The cutoff is roughly a 2 in pipe rating. Below it, the Ridgid Power Spin+ is a good bathroom tool at the lowest price position. Above it, the K KORKUAN and Milwaukee take over. The other three sit between: the Populo 20V for beginners with a complete kit, the Ublue for a value 2.95 in reach, the SKIL for households already in PWR CORE 20. ## FAQ ### Is a cordless drain cleaner worth it over a manual snake? A cordless drain cleaner is worth it if you clear more than one drain a year or your household has long hair, grease-prone cooking or a slow shower. A manual snake works for a shallow bathroom clog. Past 6 ft into the line, cranking by hand becomes slow and painful, and the auto-feed on every powered pick in this set removes that step entirely. ### What size drain can the best cordless drain cleaner clear? The best cordless drain cleaner in this set for 3 in lines is the K KORKUAN, rated for 3/4 to 3 in pipes on a 23.62 ft replaceable cable. The Milwaukee 2772A-21 matches that ceiling on a longer 35 ft cable. Everything else tops out at 2 in or 2.95 in, which covers kitchen and bathroom lines but not a 3 in floor drain. ### Can I use these on a toilet clog? Most cordless drain cleaners in this set are not designed for toilet clogs. The Populo 12V listing states outright that it is not for toilets. A toilet auger has a protective sleeve to keep the cable from scratching porcelain, which none of these picks offers on the input. For a toilet stoppage, use a dedicated toilet auger and keep these tools for sink, shower and floor drains. ### K KORKUAN or Milwaukee 2772A-21, which should I pick? Pick the K KORKUAN if you already own a Milwaukee M18 battery and want to pay only for the tool. Pick the Milwaukee 2772A-21 if you need 35 ft of reach, want the fully enclosed drum, or need a written 5-year tool warranty. The K KORKUAN is a bare tool at a mid position; the Milwaukee is a full kit at the top of the price range in this comparison. ### What is the biggest mistake people make buying a cordless drain cleaner? The biggest mistake buying a cordless drain cleaner is comparing voltage first. Voltage sets torque, which matters for cutting, but pipe diameter rating and cable length decide whether the tool can reach the clog at all. Check those two figures on the listing before you look at the battery specification. A 12V tool with the right cable clears more real clogs than a 20V tool that is too short or too wide for the pipe. A cordless drain cleaner earns its shelf space the first time it saves you a service call, and the K KORKUAN is the pick most likely to do that in the widest range of homes. It handles the 3 in floor drain and the 3/4 in shower line on the same cable, and it plugs into a Milwaukee battery you may already own from another tool. Match the pipe rating and the cable length to the drains in your house before you order, keep a spare cable on the shelf if the model supports it, and treat the voltage number as the last thing you look at rather than the first. *Last updated: September 11, 2026\.
