The iRobot Roomba Plus 505 Combo includes both a HEPA filter and an allergy filter, making it suited for environments where air quality during cleaning is a consideration. It operates at an audible noise level of 65.7 dB and is compatible with both Google Assistant and Alexa for voice control. The unit weighs 4300 g and has a width of 351 mm, a height of 106 mm, and a thickness of 357 mm, giving it a total volume of 13282.542 cm³, while the docking station is considerably larger at 72756 cm³. The dustbin is estimated to require emptying roughly every 150 days, and the product is backed by a 1-year warranty.
The Roomba Plus 505 Combo offers a well-rounded set of navigation and control features, including route mapping, no-go zones, and virtual barriers to give users control over where and how the robot cleans. An obstacle sensor and anti-fall sensor help it navigate safely, and an anti-stuck mechanism reduces the likelihood of it getting stranded mid-clean. The unit supports scheduled cleaning, auto-docking, and smartphone remote control via Wi-Fi 4 (802.11n), though it does not include a physical remote control. Voice prompts are supported for on-device feedback. On the mopping side, it features mop cleaning, mop raising, and mop drying, covering the full mopping cycle automatically. It is worth noting that the robot is not self-emptying, so the dustbin requires manual attention.
The Roomba Plus 505 Combo has a dustbin capacity of 0.3 litres, which requires manual emptying as the unit does not include a full indicator to signal when it is full. The robot does not feature a display, twin side brushes, or automatic height adjustment, and the included filters are not washable.
The Roomba Plus 505 Combo delivers 7000 Pa of suction power and is capable of cleaning all floor types, complemented by mopping functionality for a more complete clean. It offers four cleaning modes, giving users some flexibility in how each session is handled. A built-in dirt sensor allows the robot to detect and respond to areas with heavier soiling, while UV light is not included.
The Roomba Plus 505 Combo is powered by a 5000 mAh battery that supports up to 120 minutes of runtime per charge, with a full recharge taking approximately 3 hours. Operating power consumption is rated at 110W, and the unit includes an auto-off function to conserve energy when not in use.
