When you’re looking at robot vacuum replacement parts UK listings, start with the exact model of your robot and, where relevant, its dock. Then identify the component and look for explicit compatibility evidence naming that model. Check what is actually in the pack before you order. A part that looks the same, or sits in a listing with a similar name, is not proof that it fits.
Bot ‘n’ Brush has not performed fitting trials on any part mentioned here. This guide is based on the manufacturer and retailer pages named below, read on 1 November 2026. It explains how to check a listing, not which part to buy.
Step 1: Identify the exact robot and dock
Start with the full model identifier, not the marketing name. Two products with similar names can be different models, and a dock can have its own identifier.
As one labelled example, SharkNinja’s parts and support page tells owners to search by model number and says it is listed on the front cover of the instruction booklet. SharkNinja’s robot-vacuum parts pages also describe finding the number near the barcode on the box. That wording comes from SharkNinja’s search-result text, and the page I read is on its global site, not the UK site. This is Shark’s guidance for Shark products. Other brands may use different locations, so check your own manual or the manufacturer’s support pages.
Shark UK’s RV2800ZEUKWH product page also shows a trap. It uses the word “Model:” for the whole product (RV2800ZEUKWH) and for individual parts (for example the side brush code 820KKU2800WDEU). A “model” code in a parts listing may therefore be a part number, not your robot’s model. Keep three things separate:
- The model number identifies your robot or dock.
- The part number (or accessory code) identifies the replacement item.
- The serial number identifies your individual unit. Don’t publish it publicly.
Step 2: Identify the component
Next, decide what exactly you are replacing.
- Robot or dock? Establish which unit the replacement belongs to. A robot filter and a dock filter are not interchangeable merely because both are called filters. If a dock is involved, identify it separately from the robot.
- A consumable or a larger assembly? On Shark UK’s RV2800ZEUKWH product page, the add-ons list a side brush alongside a “Replacement Pod (Robot)”. A pod is a major assembly, not a consumable. This guide covers only the consumable parts an owner replaces by hand. It doesn’t cover batteries, chargers or internal repairs, so don’t open housings or batteries.
- A part or a holder? Some listings sell the pad itself, others a plate or frame for it. Read the product name closely.

Step 3: Look for explicit compatibility evidence
The strongest evidence is a manufacturer statement naming your model or a family that your model belongs to. A seller’s claim is useful, but it is weaker, because it comes from the seller.
| Evidence | What it tells you | What it doesn’t tell you |
|---|---|---|
| Manufacturer lists your exact model | The manufacturer states compatibility | Anything about kit contents |
| Manufacturer lists a series that includes your model | The manufacturer states family compatibility | Models outside the family |
| Seller says “fits” or “compatible” | The seller’s claim | That the manufacturer agrees |
| Your model is not mentioned | Compatibility is unestablished | That the part is incompatible |
| Similar photo, size or name | A reason to investigate the listing further | Confirmed compatibility |
Example A: a manufacturer’s explicit list
Roborock UK’s dust-bag listing says the bags are compatible with the S8 MaxV Ultra, S8 Max Ultra, Qrevo S, Qrevo, Qrevo MaxV, Qrevo Pro, Qrevo Plus, Qrevo Master, Qrevo Slim, the Qrevo Curv Series, the Qrevo Edge Series and the Saros Series. This is manufacturer-stated compatibility, and a series name is still evidence. If your robot is named, or you can confirm on Roborock’s own range pages that your exact model belongs to a named series, you have good evidence for that part. The page doesn’t say the list is exhaustive, so a model that is missing is unestablished, not excluded.
Example B: wording that doesn’t line up
Roborock UK’s four-pack mop-cloth page is titled “Mop Cloth*4pcs for Qrevo Curv 2 Pro, Qrevo CurvX”. Its Key Features line says “Compatible with Roborock Qrevo Curv and Qrevo Edge”. How the two descriptions relate is unclear, and neither is established as exhaustive. We therefore do not resolve the difference ourselves; we ask for confirmation covering the exact model. The sensible next step is to ask Roborock’s UK support or the seller. Give them your robot and dock identifier and the exact accessory listing, and ask them to confirm compatibility in writing before you order.
An omitted model is unestablished
If your model isn’t named, you haven’t learned that the part is incompatible. Unless the source explicitly excludes it, treat it as unestablished. In the same way, different identifiers on two parts don’t prove they are incompatible, and a listing that groups several models doesn’t prove yours is covered.
Step 4: Check what is in the pack
Compatibility and contents are separate questions. A kit can be compatible and still not contain the part you need.
Look at which components are included, how many of each, and whether a pack is one part or an assembly. A bigger multi-piece kit isn’t automatically better value than the one part you need.
Example C: reading beyond a listing title
A Reliapart-branded kit on B&Q’s website is titled “Replacement Parts Kit for Shark PowerDetect NeverTouch Pro 2-in-1 (15 Piece Set)”. The title alone doesn’t say what the fifteen pieces are. The listing description does: 6 side brushes, 2 filters described as washable, 2 mop pads, 1 brush bar, 1 post-motor filter, 1 mesh-screen filter, 1 foam insert and 1 foam-cylinder insert. Those quantities add up to fifteen.
The description also states compatibility. It names the Shark PowerDetect NeverTouch Pro 2-in-1 RV2800ZEUK, and it says the kit is suitable for other codes it lists: AV2800ZEUKWH, RV2800YEEU, RV2800ZEEU, AV2800ZE, RV2820YE and RV2820Z. For the white UK package, Shark’s own product page uses RV2800ZEUKWH, while this listing names AV2800ZEUKWH. Those identifiers differ, so do not assume they refer to the same model; ask the seller to confirm compatibility for the exact code on your robot.
Everything here is the listing’s own claim: the compatibility, the contents and the word “washable”. The page text I read doesn’t show who sells the kit. We aren’t endorsing its fit, performance, equivalence to Shark’s own parts or safety. The point is only that the description, not the title, is where the contents and the model codes are stated.
Step 5: Resolve unanswered questions before ordering
Before you buy, run through this list.
- Do you have the exact model of the robot (and dock, if relevant)?
- Have you identified the component, and whether it belongs to the robot or the dock?
- Does a manufacturer page name your model or a family it belongs to?
- If only a seller makes the claim, have you asked the manufacturer or seller to confirm it for your model?
- Do you know exactly what’s in the pack, and in what quantities?
- Is any wording in the listing contradictory? If so, ask before ordering.
If you contact a manufacturer or seller, give them your model identifier, the part or accessory code, and the link to the listing.
A new part is not a guaranteed fix
Replacing a part will not necessarily fix poor pickup, an odour, noise or a dock error. Don’t assume a fault means a consumable needs replacing. For faults, see our troubleshooting guide, and for routine care see our maintenance guide.
