dreame L40s Pro Ultra Robot Vacuum Cleaner vs Roomba 105 Combo Robot Vacuum & Mop + AutoEmpty Dock - Self-Empties for 75 Days

Suction Power and Cleaning Performance

The dreame L40s Pro Ultra Robot Vacuum Cleaner offers significantly stronger suction power at 19,000Pa compared to the Roomba 105 Combo Robot Vacuum & Mop’s suction, which is described as 70 times more powerful than the older Roomba 600 series but without a specific Pa value. This makes the dreame model more capable of capturing both tiny dust particles and large debris across various surfaces, including floor gaps and carpets.

The advanced sixth-generation TurboForce motor in the dreame ensures powerful and quiet cleaning, while its HyperStream Detangling DuoBrush is designed to prevent hair tangles, maintaining cleaning efficiency. In contrast, the Roomba 105 Combo uses a 4-stage cleaning process combining multiple brushes and a microfiber mop pad, effective on multi-surfaces but without the same suction strength. Overall, the dreame’s higher suction capacity gives it an edge in deep and detailed cleaning tasks.

Mopping and Carpet Handling

When it comes to mopping and carpet care, the dreame L40s Pro Ultra offers tailored options via its app for different carpet types, including dry, low-pile, or complete carpet avoidance. It also features removable and liftable mops, enhancing its versatility to either mop or avoid carpets as needed. This level of customization helps optimise cleaning without risking carpet damage or wetting.

The Roomba 105 Combo also provides versatile cleaning modes, with the ability to vacuum only, mop only, or do both simultaneously. Importantly, it boasts automatic carpet detection that prevents mopping on rugs, safeguarding them from moisture. The Roomba’s mopping system controls water flow with a micro-pump, keeping the mop evenly moist and enabling a “SmartScrub” mode for twice as deep scrubbing. Both models offer good mopping features, but dreame’s app-based carpet strategies offer more detailed user control.

Self-Emptying and Maintenance Convenience

The dreame L40s Pro Ultra excels in maintenance convenience with its all-in-one PowerDock that can skip manual dust box emptying for up to 100 days. Additionally, the dock rinses and dries mop pads using 75°C hot water, refills solution and water, and cleans the mop board to reduce residue build-up. This hands-free post-cleaning system minimises user intervention significantly.

The Roomba 105 Combo’s AutoEmpty dock also offers impressive convenience by self-emptying for up to 75 days into AllergenLock bags that trap 99% of pollen and mould, reducing dust exposure when disposing of waste. While it lacks mop cleaning features, it still provides a largely hands-off experience for vacuum dirt disposal. In maintenance terms, the dreame’s additional mop cleaning and solution refilling services make it more comprehensive.

Navigation and Obstacle Handling

The Roomba 105 Combo uses ClearView LiDAR technology to map homes quickly, avoid obstacles, and clean efficiently in neat rows, even in darkness. This advanced mapping aids precise coverage and systematic cleaning routes, enhancing overall performance in complex layouts.

Conversely, the dreame L40s Pro Ultra employs an EasyLeap system with main and auxiliary climbing wheels that allow it to cross thresholds, door tracks, and steps up to 4cm high without getting stuck. This mechanical obstacle handling is particularly advantageous for homes with varied floor levels or door sills. While the dreame’s navigation system isn’t specified as LiDAR-based, its superior physical obstacle crossing ability complements its cleaning prowess.

App Control and Customisation

The dreame L40s Pro Ultra offers detailed carpet care customisation through the Dreamehome app, enabling users to select cleaning modes tailored to different carpet types. This app control likely extends to scheduling and other preferences, although specifics beyond carpet care aren’t detailed.

The Roomba 105 Combo supports a fully custom cleaning schedule via the Roomba Home App, allowing users to target specific rooms, adjust suction levels, number of cleaning passes, and the amount of mopping solution delivered. It also lets users create keep-out zones and provides time estimates and filter life monitoring. The Roomba’s app offers broader control features, including voice assistant compatibility with Alexa, Siri, and Google Assistant, which the dreame product description does not mention.

Brush and Dust Management

The dreame L40s Pro Ultra’s HyperStream Detangling DuoBrush combines a bristled rubber brush with a TPU rubber brush to remove debris efficiently from hard floors and carpets while preventing hair tangles. This design helps maintain powerful cleaning performance over time without frequent brush maintenance.

The Roomba 105 Combo uses a multi-surface bristle brush and an edge-sweeping brush to tackle dirt and dust bunnies effectively. While it does not specify anti-tangle features, its 4-stage cleaning system includes a microfiber mop pad for floor finishing. The dreame’s brush design appears more advanced specifically for hair removal and tangle prevention, benefiting users with pets or long hair.

Price and Value Consideration

The Roomba 105 Combo Robot Vacuum & Mop with AutoEmpty Dock retails at £179.00, making it a significantly more budget-friendly option compared to the dreame L40s Pro Ultra, which is priced at £469.00. This price difference of £290 reflects the dreame’s superior suction power, longer self-emptying intervals, mop cleaning capabilities, and enhanced obstacle handling.

For buyers prioritising a cost-effective solution with solid vacuum and mop functionality and smart mapping, the Roomba 105 Combo offers strong value. However, those seeking premium features like high suction, extensive hands-free maintenance, and advanced carpet care customisation may find the dreame justifies its higher price.

Which should you buy?

Choosing between the dreame L40s Pro Ultra and the Roomba 105 Combo depends largely on your cleaning needs and budget. If powerful suction (19,000Pa), extended self-emptying (up to 100 days), mop pad rinsing, and superior obstacle crossing are priorities, the dreame L40s Pro Ultra stands out as the more capable and convenient option, albeit at a higher price of £469.00.

Conversely, for a more affordable price of £179.00, the Roomba 105 Combo delivers competent vacuum and mop performance with smart LiDAR mapping, a 75-day self-emptying dock, and broad app customisation including voice assistant support. It is well-suited for users seeking reliable, hands-off cleaning without premium suction or mop maintenance features.

Ultimately, the dreame is best for users who want a high-end, all-in-one robotic cleaner with advanced features and are willing to invest more, while the Roomba 105 Combo offers excellent value with essential smart cleaning functions for budget-conscious buyers.
