Steam mop replacement tanks are not interchangeable by appearance alone, so matching the part to your mop’s exact model is the first step. My best overall pick is the Bissell PowerFresh 1940 Series Replacement Water Tank with Cap, which replaces the tank and cap together; the Bissell 2-pack stands out for buyers who want a spare, while the Neugo tank serves owners of NE033 and NE033M mops. The main tradeoffs are whether you need a whole tank or only a cap, how clearly the listing identifies compatible models, and whether an included spare is useful. A wrong-fit part can be more trouble than a worn original, so check the model number before ordering. Continue reading for the full breakdown of all nine options and how to choose among them.

Key Takeaways
- Model match separates the strongest options: several Bissell parts specify the PowerFresh 1940 Series, while the Neugo, Hoover, MX-C021, and STC800 tanks each target different mop models.
- A tank-and-cap kit solves a different problem from a cap-only replacement: the Bissell cap options make sense when the tank itself is intact, while full assemblies replace more of the water-storage part.
- The Bissell 2-pack is the clearest spare-oriented choice: it offers two tank-and-cap sets, which is useful when keeping a matching replacement on hand matters more than buying only one assembly.
- Brand and model detail varies across the lineup: model-specific listings provide a clearer compatibility starting point than the broadly named DEVOAC tank, so buyers should verify fit details before choosing a less-specific option.
- Capacity is not a universal ranking advantage: the MX-C021 listing specifies a 450 ml detachable tank, but compatibility with that mop matters more than capacity when replacing a failed part.

Neugo Removable Water Tank for NE033 and NE033M Steam Mops
This is the most straightforward choice for owners of a Neugo NE033 or NE033M who need a complete, removable tank rather than a small cap or seal part. Its 450 ml capacity gives it a clearly stated water volume, while the removable design makes it practical to refill separately from the mop. Compared with the TOP VACUUM PARTS two-pack for Bissell PowerFresh, this is a single tank for a narrower model family, not a multi-unit option. That makes exact model matching especially important: it is not a general-purpose steam mop tank. The tank is listed for sealed hard floors and upholstery, but care involves hand washing, so it calls for more manual upkeep than a part that only needs occasional replacement. Choose it for a confirmed Neugo fit, not for flexibility across brands.
Pros:- Compatible with the specified Neugo NE033 and NE033M models.
- Removable design supports separate filling and handling.
- 450 ml capacity is clearly specified.
- Listed for sealed hard floors and upholstery.
Cons:- Fit is limited to two specified Neugo model families.
- Requires hand washing.
- Includes one tank, with no spare cap or second tank listed.
Best for: Neugo NE033 and NE033M owners who need a removable replacement tank with a stated 450 ml capacity.
Not ideal for: Owners of other Neugo models or other steam mop brands, since compatibility is limited to the NE033 and NE033M.
- Brand:Neugo
- Model:NE033TANK
- Compatible models:NE033, NE033M
- Capacity:15.2 fl oz (450 ml)
- Weight:0.21 kg
- Form factor:Handheld
- Recommended surfaces:Sealed hard floors, upholstery
- Care instructions:Hand wash
Our verdict“Choose this single 450 ml tank if your mop is a Neugo NE033 or NE033M; otherwise, the Bissell and Hoover replacements in this roundup are model-specific alternatives, not substitutes.”
Replacement Water Tanks with Caps for Bissell PowerFresh 1940 Series Steam Mop, 2-Pack
For a compatible Bissell PowerFresh 1940-series owner who wants a spare ready, this set’s main advantage is quantity: two tanks with caps arrive together, unlike the single cap sold in the KEEPOW 203-8413 one-piece replacement. That makes this a more useful choice when replacing a damaged tank or keeping an extra available, but the listing provides no capacity measurement, so I can’t compare its water volume with the Neugo 450 ml tank. The compatibility list covers numerous 1940-series model numbers, yet it still calls for checking the exact mop before ordering. Proper setup also depends on tightening the cap and securing the insert; a tank that is not seated correctly may not function as intended. This is a practical set for Bissell owners, but not a universal tank or a cap-only repair.
Pros:- Includes two replacement tanks with caps.
- Lists compatibility with a broad range of Bissell PowerFresh 1940-series models.
- Designed to hold water for steam cleaning sealed hard surfaces.
- Provides a full tank replacement rather than caps alone.
Cons:- Exact mop model should be checked before ordering.
- Cap tightening and insert placement affect proper function.
- No tank capacity is specified in the provided product data.
Best for: Bissell PowerFresh 1940-series owners who want two replacement tanks with caps in one set.
Not ideal for: Buyers with a different Bissell series, another brand, or a damaged cap but otherwise usable tank who only need the cap replaced.
- Brand:TOP VACUUM PARTS
- Compatible models:Bissell 19404, 19401, 1940N, 1940, 19402, 19408, 19409, 1940A, 1940F, 1940Q, 1940T, 1940W, B0006, 19405
- Part number:2038412
- Manufacturer part number:TVP TANK
- Pack quantity:2
- Included components:2 replacement water tanks with caps
- Color:Blue
- Size:Medium
Our verdict“Pick this set if you have a confirmed compatible Bissell 1940-series mop and want two complete tanks, but choose the KEEPOW single cap if only the cap needs replacement.”
KEEPOW Water Tank Caps for Bissell PowerFresh Steam Mop 1940 Series, 2-Pack
When the tank itself is still usable and only its closure is the problem, these two replacement caps are a more targeted fix than the complete Bissell tanks in the TOP VACUUM PARTS set. The caps are listed for a range of PowerFresh 1940-series models, with heat-resistant plastic and precision threading intended to create a snug seal. A wide opening also makes refilling less fiddly than a narrow-mouth design. The tradeoff is scope: this purchase does not replace a cracked, missing, or otherwise damaged tank, and the fit remains limited to listed Bissell models. Compared with the KEEPOW single-cap 203-8413 option, this package supplies two caps, but the provided details do not specify a different fit or construction advantage. Verify the model and cap part before choosing this small-part repair.
Pros:- Includes two replacement caps.
- Precision threading is designed for a snug seal.
- Heat-resistant plastic is specified for the cap material.
- Wide opening supports easier refilling.
Cons:- Replaces caps only, not complete tanks.
- Compatibility is limited to specified Bissell PowerFresh 1940-series models.
- The product data does not list tank capacity or include other tank components.
Best for: Bissell PowerFresh 1940-series owners whose tanks are intact but need replacement caps, especially those who want a spare.
Not ideal for: Anyone with a cracked or missing tank, or an owner of a steam mop outside the listed Bissell 1940-series models.
- Brand:KEEPOW
- Compatibility:Bissell PowerFresh 1940, 19402, 19404, 19405, 19408, 19409, 1940A, 1940F, 1940Q, 1940T, 1940W, and 19401
- Part number:203-8413
- Quantity:2
- Material:ABS and heat-resistant plastic
- Color:Black
- Item weight:0.01 kg
- Special features:Tight seal, heat-resistant material, easy-refill design
Our verdict“Choose this two-cap pack when your compatible Bissell tank is sound and its closure needs replacing; for a damaged tank, the TOP VACUUM PARTS set is the more complete repair.”
440001701 Steam Mop Water Tank Assembly for Hoover WH20200 and WH20201
This assembly is the dedicated choice in this group for owners of a Hoover WH20200 or WH20201, replacing part number 440001701. Unlike the Bissell listings, which split between complete tanks and caps, this product is presented as one tank assembly for a narrow Hoover fit. The listing also states an 18-month warranty, giving buyers a stated coverage period that the other replacement options here do not specify. Its limits are just as clear: it is an aftermarket part, not an original manufacturer component, and it does not list a tank capacity or detailed material information. Compared with the Neugo replacement, which supplies a 450 ml capacity and care guidance, this Hoover listing gives less detail about the tank itself. Match the part number and mop model before ordering.
Pros:- Designed for Hoover WH20200 and WH20201 steam mops.
- Replaces part number 440001701.
- Includes one water tank assembly.
- Lists an 18-month warranty.
Cons:- Aftermarket replacement, not an original manufacturer part.
- Compatibility is limited to the two listed Hoover models.
- The provided data does not state tank capacity or material.
Best for: Hoover WH20200 and WH20201 owners who need an assembly identified as replacement part 440001701 and value a stated warranty.
Not ideal for: Owners of other Hoover models or buyers who require an original manufacturer part or a stated tank capacity.
- Replacement part number:440001701
- Compatible models:Hoover WH20200, WH20201
- Package contents:1 steam mop water tank assembly
- Item weight:1 pound
- Package dimensions:1 x 1 x 1 inches
- Manufacturer:HASME
- Item model number:HEG3800
- Warranty:18 months
Our verdict“This is the clearest fit for WH20200 and WH20201 owners needing part 440001701, provided an aftermarket assembly is acceptable.”
Steam Mop Water Tank Cap Replacement for Bissell PowerFresh 1940 Series
This is the focused repair option when a compatible Bissell tank is intact and only its cap needs replacing. Its twist closure, threaded seal, and heat-resistant ABS plastic are intended to help the cap fit securely and handle steam-mop use; the wide-mouth design also supports easier refilling. Compared with KEEPOW’s two-cap pack, this listing supplies one cap, so it suits a one-part repair rather than a spare-cap purchase. It shares the same stated part number, 203-8413, but buyers should still confirm their exact model against the compatibility list. Like both cap-only options, it cannot solve a cracked or missing tank. If the tank itself needs replacement, the TOP VACUUM PARTS two-tank set is a more complete Bissell alternative, subject to model fit.
Pros:- Replaces cap part 203-8413.
- Threaded twist closure is designed to help limit leaks.
- Heat-resistant ABS plastic is specified.
- Wide-mouth design supports easier refilling.
Cons:- Includes one cap only.
- Does not replace the tank or other components.
- Fit is limited to the specified Bissell PowerFresh 1940-series models.
Best for: Bissell PowerFresh 1940-series owners who need one replacement cap for an otherwise usable tank.
Not ideal for: Buyers who need a complete tank, want a spare cap, or own a model outside the listed Bissell 1940-series range.
- Brand:KEEPOW
- Model number:203-8413
- Manufacturer part number:203-8413 or 2038413
- Compatible models:Bissell 1940, 19402, 19404, 19405, 19408, 19409, 1940A, 1940F, 1940Q, 1940T, 1940W
- Material:ABS plastic
- Color:Black
- Closure type:Twist
- Quantity:1
Our verdict“Choose this single cap for a confirmed compatible Bissell tank that only needs a new closure; choose the two-cap KEEPOW pack if you want a spare.”
Selgo Replacement Water Tank with Cap for Bissell PowerFresh 1940 Series Steam Mop
The Selgo is the clearest fit for owners who have a Bissell PowerFresh 1940-series mop and need a replacement tank with its cap included. Its listed compatibility spans numerous model numbers, giving it a wider stated fit range than the STC800 replacement tank, which is limited to one named mop. The cap makes this a more complete replacement than buying a tank alone, though it does not remove the need to verify your exact model before ordering. The listing also calls out two fit-related details: the cap must be fully tightened and the insert seated correctly. That makes installation straightforward in concept, but less forgiving if either piece is misplaced. Choose it for the specified Bissell range; skip it if your mop is outside that list or you only need a cap.
Pros:- Lists compatibility with numerous Bissell PowerFresh 1940-series models
- Includes the tank cap
- Designed for easy installation
- Replacement tank is intended to hold water for steam cleaning sealed hard surfaces
Cons:- Fit is limited to the specific models listed
- The cap must be fully tightened and the insert seated correctly
Best for: Bissell PowerFresh owners whose model number appears in the compatibility list and who need both a tank and cap.
Not ideal for: Owners of other Bissell series or steam mop brands, since compatibility is limited to the listed models.
- Compatible models:Bissell 19404, 19401, 1940N, 1940, 19402, 19408, 19409, 1940A, 1940F, 1940Q, 1940T, 1940W, B0006, 19405
- Part number:2038412
- Included component:Tank cap
- Package dimensions:7.2 x 6.34 x 2.6 inches
- Item weight:4.6 ounces
- Manufacturer:Selgo
Our verdict“Choose the Selgo if you need a tank and cap for a listed Bissell PowerFresh 1940-series model and have confirmed the model number.”
Mxnsewr 450 ml Detachable Water Tank for MX-C021 Steam Mop
The Mxnsewr tank is the most refill-focused option in this group: its 450 ml capacity, wide fill port, and silicone sealing ring are aimed at making water top-ups less fiddly. The quick-release buckle also lets an MX-C021 owner detach the tank for filling rather than handling the whole mop. That is a different advantage from the Selgo Bissell tank, which offers a broader list of compatible model numbers but does not state a capacity or highlight a wide opening. The tradeoff is strict fit specificity: this listing names only the MX-C021, so it is not a flexible choice for households with another mop. Material details are also vague, described only as high-quality materials. Buy it when your model matches and easy filling matters; pass if compatibility is uncertain.
Pros:- 450 ml stated capacity
- Quick-release buckle supports removal and installation
- Wide water-injection port simplifies filling
- Silicone sealing ring is intended to help reduce spills
Cons:- Compatibility is listed only for the MX-C021
- Material is described vaguely, without a specific material type
Best for: MX-C021 owners who remove the tank for refilling and want a stated 450 ml capacity with a wide fill port.
Not ideal for: Owners of other steam mop models, or buyers who need detailed material specifications before choosing a replacement.
- Compatibility:MX-C021 steam mop
- Capacity:450 ml
- Model number:C021-SX
- Brand:Mxnsewr
- Material:High-quality materials; specific material not stated
- Color:Gray
- Special feature:Detachable
- Unit count:1
Our verdict“Pick this tank for an MX-C021 when quick removal and a wide refill opening matter more than broad compatibility.”
DEVOAC Water Tank Replacement for Steam Mop
The DEVOAC listing gives very little information to support a confident fit decision: it names a replacement water tank but does not identify compatible mop models, tank capacity, or material. Compared with the Selgo tank, which lists a long set of Bissell model numbers, DEVOAC leaves buyers without the main detail needed to judge whether a replacement will attach and seal correctly. Its single-item listing at least makes the package contents clear, but that does not resolve the compatibility gap. I would treat this as a candidate only if the seller or another reliable source confirms the exact fit for your mop. Without that confirmation, the STC800 tank is a safer choice for STC800 owners because its target model and several practical details are stated.
Pros:- Listed as a steam mop replacement water tank
- Single-item package is stated
- Provides a potential replacement option when exact fit is confirmed
Cons:- Compatible steam mop models are not specified
- Tank capacity is not provided
- Material and further fit details are absent
Best for: A buyer who has independently confirmed that this DEVOAC tank fits their exact steam mop model.
Not ideal for: Anyone choosing a replacement based on the listing alone, since compatible models, capacity, and material are not provided.
- Brand:DEVOAC
- Product type:Steam mop replacement water tank
- Number of items:1
- Model name:Water Tank Replacement Steam Mop
- Model number:Water Tank Replacement Steam Mop
- Part number:Water Tank Replacement Steam Mop
- Manufacturer:DEVOAC
Our verdict“Consider the DEVOAC only after confirming exact compatibility elsewhere; the listing itself does not provide enough fit information.”
Replacement Water Tank for STC800 Steam Mop
For STC800 owners, this tank makes a practical case through clear water-level visibility and tool-free installation. The transparent body lets you see when a refill is needed, while the stated heat-resistant plastic is intended for repeated steam-mop use. Compared with the Mxnsewr tank, which offers a larger stated capacity and a wide fill port, the STC800 option focuses more on monitoring and swapping than on refill convenience. Its narrow compatibility is the main limit: the listing names only the STC800, so buyers with another mop should not assume a fit. The listing also does not state tank capacity, making it harder to judge how often refills may be needed. This is a sensible model-specific replacement, not a general-purpose tank.
Pros:- Transparent body makes the water level visible
- Tool-free installation supports straightforward swapping
- Heat-resistant plastic is specified for repeated steam-mop use
- Lightweight at 4.3 ounces
Cons:- Compatibility is specified only for the STC800
- Tank capacity is not stated
Best for: STC800 owners who want a transparent replacement tank that can be installed without tools and checked during cleaning.
Not ideal for: Owners of other mop models or buyers who need a stated tank capacity before choosing.
- Compatibility:STC800 steam mop
- Material:Heat-resistant plastic
- Design:Transparent
- Installation:Tool-free
- Package dimensions:6.5 x 6.3 x 3 inches
- Item weight:4.3 ounces
- Manufacturer:Phueut
Our verdict“Choose this replacement if you own an STC800 and value visible water levels over a stated capacity or broader model fit.”
How We Picked
I ranked these steam mop replacement tanks by how clearly each listing identifies the mop it fits, whether it replaces a tank, cap, or both, and how much useful information a buyer can verify before ordering. A precise model match matters more than a broad claim of compatibility: a tank that does not seat or seal correctly will not solve the repair.
I also weighed the practical value of included parts and pack quantity against the risk of buying more than the repair requires. That puts model-specific tank-and-cap replacements ahead for shoppers needing a full replacement, while cap-only products earn a place for a narrower repair. The order reflects clarity and usefulness for different repair needs, not a claim that every part fits other mop models.

Factors to Consider When Choosing Steam Mop Replacement Tanks
Choosing a replacement tank is a parts-matching decision, not just a search for a container with a similar shape. Before buying, identify what has failed and check the mop’s exact model number; those two steps can prevent a mismatch and an unnecessary full assembly purchase.
Match the exact mop model, not just the brand
Steam mop parts can look alike while differing in their mounting points, fill openings, or connection details. Find the model number on the mop’s label or in its manual, then compare it with the compatibility information on the listing. A brand name by itself is not enough, especially when one maker sells several mop designs. If a listing names only a product family, check whether your precise model is included before placing an order. When the fit information is unclear, asking the seller for confirmation is safer than relying on a visual match.
Work out whether the tank, cap, or both have failed
A crack or leak in the reservoir points toward a tank replacement, while a damaged or missing closure may call for a cap-only part. Replacing the whole tank when only the cap is worn can mean buying parts you do not need. The reverse mistake is choosing a cap when the tank body or its connection point is damaged. Inspect the original part for visible cracks, worn threads, and damage where it attaches to the mop. If the source of a leak is uncertain, compare the replacement photos and part description with the original before deciding.
Check what the listing includes
Listings may offer a tank alone, a tank with a cap, or multiple replacement sets. Do not assume that a pictured cap, seal, or accessory comes with the part; confirm the written contents. A two-pack can suit households that want a spare, but it may be unnecessary if only one part needs replacing. A single tank-and-cap assembly can be the simpler choice when both pieces are worn or missing. Compare the included parts with what you actually need to avoid paying attention to pack size while overlooking an essential component.
Treat capacity as a supporting detail
A larger reservoir can mean fewer refill stops, but capacity only helps if the replacement fits and works with the mop. Tank shape, attachment points, and closure compatibility matter first. Compare stated capacity with your original tank when the listing provides a figure, and avoid assuming that a larger tank will fit simply because it looks similar. For a like-for-like repair, matching the original design is usually a more useful goal than changing capacity. A detachable tank can also make filling easier, but only if its connection is made for your specific mop.
Think about seals and leak prevention
A tank can appear compatible yet still leak if the cap does not seat properly or a sealing surface is damaged. Check whether the replacement includes the cap and any seals described by the seller, rather than assuming they are part of the assembly. Compare the closure and connection area with your original component, since those details often matter more than the tank’s overall outline. After installation, follow the mop’s instructions for filling and fitting the part, and check for leaks before normal use. Avoid forcing a replacement that does not attach smoothly, since pressure can damage the tank or the mop.
Use listing specificity to judge uncertainty
A listing that names a mop model gives you a clearer compatibility check than a generic replacement-tank title. Look for the full model identifier, not just a brand name or a broad phrase such as “steam mop.” Product photos can help compare shape and attachment points, but they do not prove fit on their own. If the listing leaves out model details, treat that as unresolved uncertainty rather than assuming wide compatibility. Buying from a seller with a clear return process can reduce the risk when a part’s fit cannot be confirmed in advance.
Frequently Asked Questions
How do I know whether a replacement tank will fit my steam mop?
Start with the exact model number printed on the mop or listed in its manual, then compare it with the models named in the replacement listing. Do not rely on brand name or appearance alone, since tanks can differ at their mounting points and fill connections. Check the product photos against the original part as a secondary check, not as proof of compatibility. If your model is not listed, ask the seller before ordering rather than assuming a near-match will work.
Should I replace the whole tank or just the cap?
Choose a cap-only part when the reservoir is sound and the problem is limited to a lost, cracked, or poorly fitting cap. A full tank assembly is the better match when the reservoir itself is cracked, leaking, or damaged at its connection. Check the tank and cap separately before buying; a leak can come from either part. If the listing does not make clear whether the cap is included, confirm the package contents rather than counting on the product photo.
Are the Bissell PowerFresh 1940 Series replacement parts interchangeable with other Bissell mops?
The listings in this roundup identify the PowerFresh 1940 Series, so that is the model range buyers can verify from their stated compatibility. The shared Bissell name does not establish that a tank or cap fits a different series. Compare your mop’s full model number with the listing before ordering, including any suffix shown on the product label. If the listing does not name your model, ask the seller for a fit confirmation.
Is a two-pack of replacement tanks a better choice than a single tank?
A two-pack is useful if you want a spare or expect to replace matching parts together, but it is not automatically the better repair choice. If one tank is all you need, an extra assembly may sit unused, while a single replacement can meet the immediate need with fewer parts to store. Check whether each set includes a cap and whether both are specified for your mop model. Pack quantity should come after compatibility and the exact part you need.
What should I do if the replacement tank fits loosely or leaks after installation?
Stop using the mop and remove the tank according to the manufacturer’s instructions. Check that the part is the correct model, seated in the intended position, and fitted with the included cap or seal as directed. Look for visible damage or debris around the tank opening and the mop’s connection point; do not force a loose or misaligned part into place. If the fit remains uncertain, contact the seller or mop manufacturer before using the appliance again.
Conclusion
For most shoppers needing a complete replacement, I recommend the Bissell PowerFresh 1940 Series tank with cap as the best overall choice because it addresses both parts in one model-specific listing. The Bissell 2-pack is my best value-style pick for buyers who want a spare, while the single tank-and-cap options suit those who need one replacement set. For beginners, I would start with a listing that explicitly names the mop’s exact model and includes the cap, rather than piecing together separate parts. The KEEPOW or Bissell cap-only options fit the specific need of replacing a cap while keeping a sound tank; the Neugo, Hoover, MX-C021, and STC800 tanks are for owners of those named mop models. I would treat the broadly titled DEVOAC tank as a fit-check-first option, and choose any premium-style assembly only when its exact compatibility and included parts justify it.
