Owners of the Brother 2340CV coverstitch machine describe a machine that rewards patience. Once it is set up, they praise even, stretchy cover stitch hems, and many find it easier to thread than a serger. The repeated complaints are fussiness: tight tension that needs adjusting per fabric, work that is awkward to pull out from under the foot, and reliability reports ranging from a returned unit to a chain stitch that would not form. Some owners report no problems at all. This read covers 22 Reddit threads and 2 retailer pages from 2011 to 2026, with 38 owner voices. Reddit threads lean toward people asking for help, so problems are over-represented here. See the counted themes
VerdictSpecs checked against Brother data · Checked Oct 2026
8.0/108.0
out of 10
A low-priced Brother coverstitch and chain stitch machine with no knife, no free arm listed and a fussy reputation, so it suits a knit sewist who already owns a serger.
Who it's for
A sewist who already has a serger and wants 3 mm or 6 mm cover stitch hems and a chain stitch on knits, and who will invest in setup and patience.
Skip it if
You need a free arm, a tension release lever or a published bed size: Brother lists the first two on the CV3440, and Janome states a 4 x 5.5 in bed for the CoverPro 2000CPX.

DiffersWhere sources disagree
- Weight: the Brother User's Guide gives a machine net weight of 7.0 kg (15.4 lb, OCR reading) and a retailer listing gave 16.7 lb, which may be a shipping weight; the manual figure is used.
- Frame: a retailer listing says metal frame, but no Brother document states frame material, so the claim is unverified.
- Included feet: our earlier spec listed a standard foot and a hem foot from a dealer page; Brother's page says 'Special Presser Foot' and the User's Guide box list names a snap-on presser foot and a special presser foot (C1), with no hem foot listed.
- Warranty: Brother's page says '1/5/25 Year Limited Serger Warranty' while a dealer listing says 25 yr chassis, 6 yr electronics, 2 yr parts and labor; the 1 versus 2 and 5 versus 6 do not match, and the PDF linked from Brother's page is a 1 year Latin America and Caribbean warranty, so the breakdown is unconfirmed until a US document is found.
- Speed: Brother's product page and 2015 brochure say 1,100 spm, while the User's Guide gives 1,000 spm for normal sewing speed (OCR reading); the page figure is used.
- Ratings: Amazon's 4.3 from 1,204 ratings pools several listings that share a parent (B005GXPO70 and B0DK65HMDR), so it is not a single-listing rating; the Sewing Machines Plus 4.72 from 40 has only 2 reviews naming the 2340CV, so it is not quoted as a model rating.
- Type: Brother's page body calls it 'an advanced serger' while its own spec table lists overlock seam width as N/A; it is a coverstitch and chain stitch machine with no knife and no overlock stitch.
Manufacturer claims we quote but do not assert (5)
- "An advanced serger" (Brother product page wording; the page's own spec table lists overlock seam width N/A)
- "Professional hems, chain stitch and decorative stitching" (Brother product page)
- "Great for making the perfect T-shirt in no time" (Brother product page)
- "Differential feed for perfect seaming on virtually any fabric type" (Brother product page)
- "Sturdy metal frame" (retailer listing title, not stated by Brother)
Strengths
Brother publishes 3 mm and 6 mm cover stitch, triple cover and a 2 thread chain stitch, with differential feed 0.7 to 2 and stitch length 2 to 4 mm confirmed in its documents
Owners report threading as mostly easy, with some finding it easier than a serger, though a few call it not intuitive and one hit a spool cap fit problem with non-cone thread
Owners describe the cover stitch hem as stretchy and even once set up, one calling it the stretchiest hem they had managed at home, while the triple cover hem uses a lot of thread
Weaknesses
Owners report reliability and defect problems in the largest theme (18 voices, mostly negative), with a returned unit, a fussy machine and chain stitch that fails to form; the sample skews toward people asking for help
Owners report tension is tight and needs adjusting per fabric, and removing work from under the foot is the trickiest step; Brother lists a one-touch tension release lever on the CV3440 but none on the 2340CV
Brother does not publish the throat or bed size, machine dimensions, motor power or whether there is a free arm, so these stay [verify]
Check before you buy
3 checks01
It is a coverstitch machine, not a sergerBrother's page body calls it 'an advanced serger', which is a claim. Its own spec table lists overlock seam width as N/A, the machine has no knife and no overlock stitch, and you still need a serger or a sewing machine for seams.
02
Warranty breakdown is unconfirmedBrother's page says '1/5/25 Year Limited Serger Warranty' without saying which period covers what. The linked PDF is a 1 year Latin America and Caribbean warranty, and a dealer lists 25, 6 and 2 years. Ask the seller for the US terms in writing.
03
Check the box and the frame claimBrother lists a special presser foot, and the User's Guide box list shows a snap-on foot, a special foot (C1) with an optional attachment and an accessory bag, with no hem foot. A metal frame is a retailer claim that no Brother document states.

Questions people ask
Can the Brother 2340CV do a chain stitch?
Yes. Brother lists a 1 needle, 2 thread chain stitch. One owner reports a new unit that would not form it, though cover stitches worked, and another can chain off only about an inch before the thread fails.
Can the Brother 2340CV serge or overlock?
No. Brother's page body calls it 'an advanced serger', but its own spec table lists overlock seam width as N/A and its documents list no overlock stitch. It has no knife, so seams still need a serger or a sewing machine.
What needles does the Brother 2340CV use?
The User's Guide names SCHMETZ 130/705H 90/14, with 3 needles supplied. It suggests the SUK ball point 130/705H 90/14 to reduce fabric damage; that is a suggestion, not a requirement.
Is the Brother 2340CV good for beginners?
Owner accounts are mixed. Threading is mostly reported as easy (7 of 10 statements positive) and some owners find it easier than a serger, but reliability reports lean negative (14 of 19 statements) and owners describe tight tension that needs adjusting per fabric and work that is awkward to remove from under the foot. No Brother document in our read lists a tension release lever for the 2340CV. Reddit leans toward people asking for help, so problems are over-represented.
Why does the Brother 2340CV skip stitches on knits?
Owner accounts tie it to setup. One owner who replaced a Baby Lock coverstitch says it has never skipped a stitch, while others call it finicky and say it skips until needles are fresh and matched to the fabric. A long PatternReview thread says the split tracks with setup, needle choice and stabilizer on thin knits. Brother's User's Guide names SCHMETZ 130/705H 90/14 needles and suggests a ball point SUK for knits.
What is the difference between the Brother 2340CV and the CV3440?
Brother lists a one-touch lever tension release and a free arm on the CV3440; the 2340CV page, manual and brochure list neither. The CV3440 page lists a 1,000 maximum sewing speed and a thread cutter, while the 2340CV page lists 1,100 and its manual says 1,000. On Brother's pages checked 2026-10-02 the CV3440 showed $699.00 and Out of Stock, against $579.99 for the 2340CV.
How does the Brother 2340CV compare with the Janome CoverPro 2000CPX?
Janome's page, as recorded in our briefing, lists the CoverPro 2000CPX with a tension release lever, a free arm, a 4 x 5.5 in bed, 1,000 spm, differential feed 0.5 to 2.25 and an MSRP of $1,099. Brother's 2340CV pages list no tension release lever, no free arm and no bed size, and Brother lists it at $579.99 (seen 2026-10-02).
What feet come with the Brother 2340CV?
Brother's page lists a 'Special Presser Foot'. The User's Guide box list shows a snap-on presser foot on the machine and a special presser foot (C1) used with an optional attachment, plus an accessory bag with a needle set (3 pcs), 4 thread nets, tweezers, 4 spool caps, 4 spool mats, a cleaning brush, a hex wrench and a soft cover. No Brother document lists a hem foot.
How much does the Brother 2340CV cost?
Brother USA lists the 2340CV at $579.99 (seen 2026-10-02), and its page also links a dealer locator. Prices drift, so use the price band on this page as the stable guide.
