For dust behind a radiator, choose the crevice-tool setup before comparing headline vacuum specifications: a supplied long flexible nozzle, or a flexible attachment confirmed to fit the exact model, addresses the awkward gap more directly than a floorhead. In a shared house, also check the stated runtime conditions, battery and charging arrangement, bin and supplied tools; an ordinary short crevice tool may clean edges without reaching the whole gap.
If settled dust behind radiators and furniture is your main concern, check the nozzle’s reach, flexibility and fit with the vacuum before focusing on floorhead features. Bosch and Dyson describe flexible tools for difficult-to-reach spaces.
If several housemates will use the vacuum for quick jobs, consider how it charges, whether the battery can be removed, how the bin empties and whether it converts to handheld use. VAX and Bosch list different battery arrangements for the models discussed below.
If managing disturbed dust matters to your household, check the exact model’s filtration description, bin-emptying method and maintenance instructions rather than assuming all cordless vacuums handle fine dust alike.
Start with the space you need to reach and the tool that can enter it. Then assess whether the same vacuum’s charging, handheld and dust-emptying arrangements work for everyone who will use it.
| Concern | What to check | Who this matters to |
|---|---|---|
| Reach behind the radiator | Measure the accessible gap. Check for a supplied long flexible nozzle or confirm that a flexible attachment fits the exact vacuum model. | If the gap is deep or bends around pipework, I need a tool that can follow it rather than just clean the visible edge. Around 36% of consumers put radiator-gap reach first. |
| Runtime and shared charging | Read the runtime test conditions, then check charging time, battery removability and the number of batteries supplied. | When housemates use the vacuum between charges, I want to know whether it will be ready for the next job. For around 29% of consumers, reliable handovers and charging are the primary concern. |
| Everyday versatility | Check handheld conversion, supplied tools, bin capacity and the floor types specified for the exact model. | If this is also our everyday vacuum, I need it to handle ordinary rooms and smaller cleaning jobs, not only radiator edges. That wider shared-house use comes first for around 21% of consumers. |
| Dust handling and safe ownership | Review model-specific filtration and bin-emptying instructions. For UK use, check the plug and use a charger and battery verified as suitable by the manufacturer. | If emptying stirs up dust or chargers get mixed up, I want clear maintenance and charging arrangements. Around 14% of consumers primarily prioritise dust handling and safe ownership. |
A standard crevice tool can address edges, but its presence alone says nothing about whether it is long or flexible enough to follow your radiator gap.
Measure the accessible space and check the exact bundle or the attachment’s model compatibility before choosing.
If the supplied tool cannot reach, you may need a separate compatible attachment.
Maximum figures depend on test conditions. VAX states that the Pace CLSV-PAKS up-to-40-minute figure was measured in standard power mode on hard floor with the floor brush switched off.
Read the runtime footnote alongside the charging time and supplied battery arrangement, especially if housemates will use the vacuum in separate sessions.
Electrical Safety First advises using the original charger or one the manufacturer verifies as suitable, together with manufacturer-verified batteries.
Keep the approved charger identifiable in the shared house. Do not use a plug, cord or charger that shows damage.
Accessories and availability are model-specific. Bosch listed a long flexible nozzle with the BCS712BGB, but marked that model unavailable on its UK page on 6 October 2026; Dyson’s flexible-tool page marked the accessory out of stock on that date.
Before ordering, check the precise model number, supplied-tool list and current availability on the product listing.
Consider the specific Unlimited 7 BCS712BGB configuration if a supplied long flexible crevice nozzle is central to the job.
The Pace CLSV-PAKS is a stick-to-handheld option for everyday shared-house cleaning when a standard crevice tool may suit the radiator access.
A model-compatible flexible crevice attachment is an option if you own or are considering a Dyson cordless vacuum.
No; check compatibility with the exact vacuum model before buying. Dyson lists compatible machine families for its Flexi Crevice Tool, while Bosch directs buyers to check its accessory against their appliance model number.
Not necessarily: the figure applies to its stated test conditions, which may differ from how you clean. For the Pace CLSV-PAKS, VAX specifies standard power mode on hard floor with the floor brush switched off for its up-to-40-minute figure; also check charging time and battery count.
Use the original charger or one verified as suitable by the manufacturer, and a battery the manufacturer verifies as suitable. Electrical Safety First also advises checking the plug and cord for damage and not using damaged equipment.
Consider repair, reuse or donation if the vacuum is suitable; otherwise, use an appropriate electrical-recycling route rather than general rubbish. Recycle Your Electricals identifies retailer take-back, household recycling centres and electrical-recycling points as options for vacuums with a plug, battery or cable.
