I normally don’t write reviews for products but this robot vacuum is one of the absolute best purchases I’ve made. We have 4 medium to large dogs and as you can imagine it gets very dirty very quickly. There have been many fights over who will clean the floors and when they will clean them to keep a long story short. We have tried the iRobot Roomba vacuum but the rollers would get very tangled and it didn’t have any sort of mapping or options when it came to cleaning. It also tends to get stuck where our hardwood floors turn to tile. Well, let’s just say we bought 2 of these during the Christmas sale and we have used them every single day! Our downstairs is divided into 2 areas so we got one for each and within one hour of run time, the vacuums are done. They get every nook and cranny of each room and are smart enough to get out of tight spaces. They also have different settings depending on your preferences. We did the quiet setting the first time we used it to get the most out of the battery life and to test it while our family was asleep. No one even knew it was running! The next day we did it on the regular/standard setting and it was also extremely quiet yet super powerful. These also have little to no problem crossing our various floor types, including between our hardwood and tile and rugs! Our dogs are typically very nervous and scared of the vacuum so we were a little worried about how they would handle it but they didn’t even know it was running so they just laid in their beds watching it and sleeping. It’s small enough to get under our couch and between various chairs we have in both spaces. It doesn’t push our dog bowls and rugs around like the iRobot. While I do wish it had a larger bin, I love not having to worry about pulling hair out of a roller brush! The mapping, suction, settings, and overall ability of these vacuums are PHENOMENAL! I would recommend these vacuums to anyone and everyone with hard floors and pets!
