| YOUR SHORTLIST2 products4 specifications | ||
|---|---|---|
| 01 / Everyday fit | ||
| Who it may suit | Consider it when dock automation and mixed hard-floor and carpet handling matter more than a compact setup. | Consider it if edge-reaching hardware and automatic mop upkeep are high on your list. |
| Worth checking | Measure the dock space and check bag, cleaning-solution and mop-maintenance requirements. Do not substitute L40s Ultra AE or CE specifications. | Roborock says the app is required for intended operation. Check Wi-Fi compatibility, dock dimensions and the ongoing cost of supplies. |
