If you’ve been waiting for a robot vacuum that actually handles the whole job — picking up pet hair, finding its own way around the house, and emptying itself when it’s done — the Roomba Plus 504 Vac is worth a close look. It ships with an AutoEmpty Dock as a complete package, making it a capable option for households that want genuine automation without constant upkeep.

Product Overview
The Roomba Plus 504 Vac sits in iRobot’s 2025 Plus lineup as a vacuum-only model, distinguished from the combo variants by its focus on suction performance. At 7,000 Pa, it delivers substantially more suction than older Roomba series — the brand notes this figure as 150x greater than the Roomba 600 series in spot clean mode with a full battery. The dual rubber brush design is central to that performance: the patented rollers flex against the floor surface to maintain consistent contact regardless of whether you’re on hardwood, tile, or carpet. That flexibility also reduces the hair tangling that plagues traditional bristle brushes, which matters if pets are a regular part of the household.
Navigation is handled by ClearView Pro LiDAR, which builds accurate floor maps even in low-light conditions. Initial mapping takes roughly 8 minutes, after which the robot stores up to five separate floor plans with auto-labeled rooms. From there, the Roomba Home App lets you direct cleaning to specific rooms or defined zones, adjust suction across four levels, or trigger repeat passes on high-traffic areas. The robot also builds a usage history over time, learning which spaces get dirty most often and adjusting its priorities accordingly. PrecisionVision AI works alongside the LiDAR to handle real-world obstacles — the kind of everyday clutter that trips up simpler navigation systems.
The AutoEmpty Dock handles bin management automatically. After each cleaning run, the robot returns to the dock and the dock pulls debris from the bin into an enclosed bag that holds up to 75 days’ worth before needing a change. The enclosed bag design keeps the emptying process contained, which reduces airborne dust during disposal. Filtration captures particles as small as 0.7 microns, which covers fine dust and common allergens. For users who want to run the vacuum without actively managing it between sessions, the combination of a long-runtime battery (up to 210 minutes) and a high-capacity dock means the robot can operate across larger homes without frequent intervention.
