iRobot Roomba Plus 504 Vac Robot Vacuum with AutoEmpty Dock – Superior Power-Lifting Suction, Anti-Tangle Dual Rubber Brushes, Perfect for Pet Hair, Self-Empties for 75 Days, Avoids Obstacles, LiDAR

Best Robot Vacuum I’ve Owned — Great Value for the Cost
I’ve tried a few robot vacuums over the years, and this Roomba 504 has easily been the best by far. The suction is powerful enough to actually lift pet hair and dust instead of just moving it around, and the LiDAR mapping is spot-on. It navigates neatly around furniture, doesn’t slam into walls, and somehow manages to cover every inch of the floor without missing spots.The self-emptying dock is a total game-changer. I used to have to empty my old robot’s bin almost daily, but now it just empties itself and keeps going. It really can go weeks without me touching it, which makes it feel like I’ve outsourced cleaning altogether.The obstacle detection is smarter than I expected, too — it avoids cords, shoes, and even my dog’s toys without getting tangled up. Setup was quick, and the app makes it super easy to customize cleaning schedules or target certain rooms.For the cost, this thing is honestly the best value I’ve found. It performs like a top-tier model, keeps my floors spotless, and saves me a ton of time. If you’re looking for a robot vacuum that actually delivers on what it promises, this is the one to get.

Very good vacuum, mediocre Control Ap
I received my Roomba 504+ last evening and set it up today for first time use. It was very easy to unpack and prepare for use. The wifi connection to my 5G router was quick and easy. After downloading the associated Ap on my iphone, I found and read the user manual and used the Ap to start mapping. In my opinion, the Ap is very crude and weak in functionality and usability. I give it a 2star rating. Because it was not intuitive or very diversely functional. I came very close to returning this Roomba after fighting with it most the day! However I persisted trying different options on the Ap until I figured the whole first floor map was too large to vacuum in one mission. Each time the roomba would get halfway thru the map then need to go recharge the battery. After recharging it resumed vacuuming but all prior progress on the map was lost and the vacuum would start over at the beginning of the map. This has to be an error in the software. I could never find a way to resume where it last left off. To work around this problem I searched and experimented until I was able to divide the map into reasonable sized rooms, using merge and split, named the rooms and then vacuumed by room. I also set different vacuum settings for each room to optimize the battery power. I adjusted suction and # of passes per room according to usual amount of traffic. Then I started launching an automation for each Room, one by one. Im still learning the Ap so havent discovered how to string automations together by day/time. But at least Ive decided to keep this Roomba and continue testing it. The actual hardware is very good. It has good lidar mapping, good cleaning power and very configurable. I gave it 4stars for the quality and functionality of the hardware. My only complaint is that Roomba desperately needs to improve their Ap.
