A robot cleaner collision bumper kit can mean a complete front housing, a bumper assembly, or a small sensor component, so the first choice is matching the repair part to the fault and exact vacuum model. I put the Goodsby Roomba Plus 504/505 housing first for its stated original-style mounting fit, and the SCREENTRONICS MAX 705 assembly is the more complete fit for owners of that Vac series. For Roomba i7 and E5 owners, the two RFJZFRJ listings describe similar soft bumpers, while the Deebot T9 light bar sensor addresses a narrower sensor replacement. The main tradeoff is repair scope: replacing a whole bumper can address damaged housing, but a sensor-only part is the more focused option when the bumper itself is intact.

Key Takeaways
- Goodsby is the lead pick for listed Roomba Plus 504/505 Combo models because its housing is described as matching original dimensions, clips, and mounting points.
- SCREENTRONICS is the dedicated complete bumper cover assembly for MAX 705 Vac models; it does not fit Combo Mop versions.
- The RFJZFRJ B0F22CJ6C1 and B0F22DY8SS listings both target Roomba i7 and E5, so compare listing details carefully rather than assuming they are different repair designs.
- The Deebot T9 part is a bumper light bar sensor, not a complete bumper housing or assembly; choose it only when that specific sensor is the needed repair.
- None of the supplied product details supports car back vacuum use, so these are robot vacuum repair parts rather than suitable picks for a handheld vehicle vacuum.

Replacement Front Bumper Housing for iRobot Roomba Plus 504/505 Combo Robot Vacuum (RCF-Y1, K151020, N185020, N185040, N185060)
The Goodsby front bumper housing earns the lead spot because its description gives buyers useful fit cues: it says the housing matches original dimensions, mounting points, and clip locations for specified Roomba Plus Combo models. That makes it a more informative choice than either RFJZFRJ listing, which names i7 and E5 compatibility but gives less detail about mounting geometry. It is designed to restore the bumper assembly and support obstacle detection, rather than replace a sensor alone like the Deebot T9 part.
The model list is specific: Plus 504, Plus 505, RCF-Y1, K151020, N185020, N185040, and N185060 Combo. That specificity helps narrow the fit, but also makes this a poor universal repair option. It is a third-party part, not an original iRobot component, and the supplied information does not establish compatibility outside those named variants. I would shortlist it for a damaged housing only after checking the robot’s exact model identifier.
Pros:- Stated match to original dimensions and mounting points
- Clip locations are described for straightforward fitting
- Designed to restore bumper function and obstacle detection
Cons:- Compatibility is limited to the named Plus Combo models
- Third-party replacement rather than an original iRobot part
Best for: Owners of a listed Roomba Plus 504/505 Combo model who need a replacement housing with stated original-style mounting points.
Not ideal for: Buyers with another Roomba generation, a non-Combo model, or a confirmed sensor-only fault.
- Brand:Goodsby
- Part type:Front bumper housing
- Compatible models:Roomba Plus 504, Plus 505, RCF-Y1, K151020, N185020, N185040, N185060 Combo
- Color:Black
- Model number:505 Front Bumper
- Mounting:Original-style dimensions, mounting points, and clips stated
- Manufacturer part number:505 Front Bumper
Our verdict“I would choose Goodsby first for a listed Roomba Plus Combo with a damaged front housing, after confirming the exact model number.”
SCREENTRONICS Front Bumper Cover Assembly Replacement for iRobot Roomba MAX 705 Vac Series Robot Vacuum (RVH-Y1, W155020, W155040, W155060)
For the Roomba MAX 705 Vac series, SCREENTRONICS is the clearest complete assembly in this lineup. Its stated direct-fit design uses original mounting points without modification, and the listing names RVH-Y1, W155020, W155040, and W155060. Those details make it a more suitable option for a full bumper-cover repair than the Deebot sensor, which replaces only a light bar sensor.
The key exclusion is easy to miss if shopping by series name alone: this part is not for Combo Mop models. Compared with Goodsby’s Plus-series housing, it targets a different and newer named family, so the ranking is based on fit clarity for its own buyer rather than broader compatibility. It is also a third-party replacement. Buyers should match the Vac variant and the robot’s part layout before ordering.
Pros:- Complete front bumper cover assembly is specified
- Direct-fit design uses original mounting points
- Model list includes four MAX 705 Vac variants
Cons:- Explicitly excludes Combo Mop models
- Third-party part, not an original iRobot assembly
Best for: Roomba MAX 705 Vac owners whose compatible listed model needs a full front bumper cover assembly.
Not ideal for: Owners of a MAX 705 Combo Mop or a different Roomba family who need a sensor-only component.
- Manufacturer:SCREENTRONICS
- Part type:Front bumper cover assembly
- Compatible series:iRobot Roomba MAX 705 Vac
- Compatible models:RVH-Y1, W155020, W155040, W155060
- Installation:Direct fit at original mounting points
- Modification:None stated as required
- Compatibility note:Not compatible with Combo Mop models
Our verdict“I would pick SCREENTRONICS over the narrower sensor replacement when a listed MAX 705 Vac needs its full bumper cover replaced.”
RFJZFRJ Robot Vacuum Cleaner Front Bumper Replacement for Roomba i7 / E5
This RFJZFRJ listing is a soft front bumper assembly for Roomba i7 and E5 models, with embedded sensors described as helping the robot detect obstacles. Its impact-absorbing material gives it a different emphasis from Goodsby’s dimension-matched housing: this listing highlights cushioning for furniture and walls, while Goodsby spells out mounting and clip alignment for its own model family. Neither description makes these parts interchangeable.
At 50 g and listed dimensions of 3 by 2 by 1 inches, the part is compact, but those measurements alone cannot confirm fit. It includes one bumper component and supplies no warranty details. The second RFJZFRJ entry also names model thbg4 and the same compatible Roomba models, so the information provided does not show a clear functional distinction between the two. I rank this listing slightly higher because it avoids the other entry’s questionable battery-life detail.
Pros:- Soft material is described as absorbing impact
- Embedded sensors are intended to support obstacle detection
- Lists i7 and E5 compatibility and one included component
Cons:- Fit is limited to two named Roomba models
- Listing provides no warranty details
Best for: Roomba i7 or E5 owners seeking a single replacement bumper assembly with stated soft impact-absorbing material.
Not ideal for: Owners of other Roomba models, or buyers who need documented warranty coverage or a broader kit.
- Brand:RFJZFRJ
- Model number:thbg4
- Compatible models:Roomba i7, E5
- Part type:Front bumper assembly
- Dimensions:3 x 2 x 1 inches
- Weight:50 g
- Quantity:1 piece
- Surface recommendation:Hard floor
Our verdict“I would consider this RFJZFRJ listing for an i7 or E5 bumper replacement when its model fit is confirmed and impact cushioning is the priority.”
RFJZFRJ Robot Vacuum Cleaner Front Bumper Replacement, Compatible with Roomba i7, E5
The second RFJZFRJ product covers the same Roomba i7 and E5 fit and describes a soft, crash-resistant bumper with embedded obstacle sensors. Its role is therefore a direct alternative to B0F22CJ6C1, not a clearly separate solution. Both listings specify model thbg4, 50 g, and nearly identical dimensions; from the supplied information, I cannot point to a distinct construction advantage that would make this the stronger i7/E5 choice.
Its main drawback is listing quality: the details include an odd “1 weeks” battery-life claim, which does not fit a bumper component. That does not prove the part itself is unsuitable, but it makes the entry less dependable as a source of specifications. Compared with the Deebot T9 sensor, this is a whole bumper component; compared with the other RFJZFRJ listing, it offers no clearer compatibility and carries the extra spec inconsistency. Match the physical part and model before buying.
Pros:- Soft material is described as crash resistant
- Embedded sensors are intended to help detect obstacles
- Lists the same i7/E5 fit as the other RFJZFRJ option
Cons:- Compatibility is restricted to i7 and E5
- Listing includes an unrelated, questionable battery-life specification
- No distinct advantage over the other RFJZFRJ listing is established
Best for: i7 and E5 owners who have checked the part they need and find this alternate listing’s component matches it.
Not ideal for: Buyers who want clean, consistent listing specifications or need compatibility beyond i7 and E5.
- Brand:RFJZFRJ
- Model number:thbg4
- Compatible models:Roomba i7, E5
- Part type:Front bumper component
- Dimensions:3 x 2 x 1 inches
- Weight:50 g
- Package contents:One bumper component
- Surface recommendation:Hard floor
Our verdict“I would place this behind the other RFJZFRJ option because its stated fit is similar but its specifications are less consistent.”
Robot Vacuum Bumper Light Bar Sensor Replacement for Deebot T9
The BSMNJDF part is the most narrowly scoped choice here: it replaces a bumper light bar sensor for the Deebot T9. If the bumper housing is intact and the needed repair is that sensor, a single component may be more appropriate than replacing a whole assembly such as the SCREENTRONICS MAX 705 cover. Its stated purpose is to support obstacle detection and navigation.
That narrow scope also limits its audience. The listing names only the T9, gives no broader compatibility information, and does not describe a complete bumper kit. Compared with the Roomba options, this part belongs to a different brand and repair system entirely. The supplied specs describe one sensor and a small package, but do not provide installation steps or a warranty. I would verify the failed part against the existing sensor before ordering.
Pros:- Clearly identified as a bumper light bar sensor
- Designed for the Deebot T9
- Described as supporting obstacle detection and navigation
Cons:- Compatibility is specified only for the T9
- Replaces a sensor, not the complete bumper assembly
- Installation and warranty details are not supplied
Best for: Deebot T9 owners seeking the specifically identified bumper light bar sensor rather than a full bumper assembly.
Not ideal for: Anyone who needs a complete bumper housing, a different Deebot model part, or a Roomba replacement.
- Manufacturer:BSMNJDF
- Compatible model:Deebot T9
- Part type:Bumper light bar sensor
- Pieces:1
- Weight:1.76 ounces
- Package dimensions:1.18 x 0.79 x 0.39 inches
- Use described:Obstacle detection and navigation
Our verdict“I would choose this only for a confirmed Deebot T9 light bar sensor fault with the bumper assembly otherwise intact.”
How We Picked
I ranked these parts by how clearly their stated fit and repair scope help a buyer choose a collision-related replacement. I gave more weight to specific model compatibility, stated mounting details, and whether the part replaces a full bumper or only a sensor. I also considered whether the listing identifies limitations that could prevent a mismatch, such as the MAX 705 part’s exclusion of Combo Mop models.
These are different kinds of components, so I do not treat a sensor as equivalent to a bumper cover. Product descriptions and supplied specifications are the basis for this guide; they do not establish independent fit verification, installation difficulty across all units, or long-term durability. The two RFJZFRJ listings name the same brand, model number, and Roomba compatibility, and one includes an unrelated battery-life detail. That inconsistency makes the individual listings harder to distinguish, so I rank them below the more clearly scoped housing and assembly options.

Factors to Consider When Choosing Robot Cleaner Collision Bumper Kit
I would start with the vacuum’s exact model and the part that is damaged. “Bumper replacement” can refer to a cover, a full assembly, or a sensor attached to the bumper. These five listings span all three, so matching the repair scope matters as much as matching the brand.
Match the model identifier, not just the brand
Check the robot’s model label or its existing part number before choosing. Goodsby lists several Roomba Plus Combo identifiers, SCREENTRONICS lists MAX 705 Vac variants and excludes Combo Mop, and both RFJZFRJ entries name only i7 and E5. The Deebot option is for T9. A shared brand name or similar-looking bumper does not establish fit across product families.
Choose a housing, assembly, or sensor
Inspect what actually failed. A cracked outer housing points toward a housing or cover replacement, such as Goodsby for its listed models or SCREENTRONICS for the MAX 705 Vac. If the bumper looks intact but its light bar sensor is the confirmed fault, the Deebot part is the targeted choice. The RFJZFRJ listings describe bumper components with embedded sensors, but the supplied details do not explain whether they include every element of a larger assembly.
Use mounting details as a fit check
Goodsby explicitly describes matching dimensions, clips, and mounting points, while SCREENTRONICS states that it uses original mounting points. These details are helpful, but they do not replace checking the actual part and model. The RFJZFRJ measurements offer a basic size reference, not enough by themselves to establish connector, clip, or sensor alignment. When a listing leaves those details unclear, compare the replacement with the original before installation.
Account for listing limitations
These are third-party replacement parts where specified, and their descriptions do not establish manufacturer authorization or independent verification. Goodsby and SCREENTRONICS both identify model boundaries; SCREENTRONICS also calls out the Combo Mop exclusion. RFJZFRJ B0F22DY8SS contains a questionable battery-life entry, while neither RFJZFRJ listing supplies warranty information. I would treat unclear specifications as a reason to verify the part number rather than infer compatibility.
Keep the car vacuum query in perspective
These products are parts for robot floor cleaners, not handheld car vacuums or automotive interior cleaning tools. The product data gives no support for using them in a car back vacuum. If the goal is to clean a vehicle’s rear seating area, these bumper parts do not address that need; choose a suitable vacuum for vehicle interiors instead of trying to adapt a robot cleaner component.
Frequently Asked Questions
How do I know which robot cleaner bumper part fits my vacuum?
Start with the exact model identifier on the robot and compare it with the compatible models in the listing. In this group, the Plus-series Goodsby housing, MAX 705 Vac SCREENTRONICS assembly, i7/E5 RFJZFRJ components, and Deebot T9 sensor each target different machines. Check the original part’s shape and mounting points as well, especially when a listing does not provide detailed fit information.
Should I replace the full bumper or only the sensor?
Choose based on the failed component. A visibly cracked or detached cover may call for a housing or full assembly, while a confirmed sensor fault with an intact bumper may call for a sensor-only replacement such as the Deebot T9 light bar. The product descriptions here do not diagnose a vacuum fault, so identify the needed part before selecting by title alone.
Are the two RFJZFRJ Roomba i7/E5 bumpers different?
The supplied details do not show a clear functional difference. Both list model thbg4, Roomba i7 and E5 compatibility, soft bumper construction, embedded sensors, and nearly identical size and weight. The B0F22DY8SS entry includes an unrelated battery-life claim, making its specifications less consistent, but that alone does not establish a physical difference between the parts.
Can I use one of these parts for a car back vacuum?
No product information here supports that use. These are collision bumper housings, assemblies, or a sensor for robot floor cleaners. They are not described as attachments or repair parts for handheld car vacuums, so a buyer cleaning a vehicle’s back seat should look for a vacuum designed for vehicle interiors.
Does the SCREENTRONICS MAX 705 part fit a Combo Mop?
The supplied compatibility note says it does not fit Roomba Combo Mop models. It is listed for the MAX 705 Vac series, including RVH-Y1, W155020, W155040, and W155060. Confirm that the robot is a Vac variant before choosing this assembly, even if the model family name appears similar.
Conclusion
I would choose Goodsby for a listed Roomba Plus Combo with a damaged housing, and SCREENTRONICS for a compatible MAX 705 Vac needing a complete cover assembly. For an i7 or E5, the RFJZFRJ listings describe similar bumper parts; I would favor the entry with clearer specifications after checking the original component. The Deebot T9 sensor makes sense only when that specific sensor needs replacement. None of these picks suits a car back vacuum use case, so buyers with that need should shop for a vehicle-interior vacuum instead.
