I have had about a half dozen robot vacs, from three different manufacturers. The early ones were lacking in power and battery, but they worked good until they died after two years each. I bought an iRobot (a lower-priced vac than this one) a couple of years ago, and since then it's been busily cleaning my bedrooms and offices effectively. It's worked almost flawlessly, as long as I clean it properly, replace the replaceable bits at intervals, and my only complaint is it's a bit noisy. I've been looking at this i7+ for a while now, and finally clicked Buy. The goal was to install it at my second house, where I visit every couple of weeks, and let it keep the dust and pet hair under control while I'm not in the house, replacing the vac bag when I do visit. To be honest, I wasn't optimistic things would go well, but I have been pleasantly surprised.A few things stand out right away compared to the older iRobot I use in my office. To start, the noise of the vac is a lot less...it's more than a buzz, but it's not sounding like industrial cleaning devices on my floors! Second, the battery seems to last longer; I can get almost an hour out of the i7+ while my older iRobot complains after about 20 minutes. Third, this one is a lot smarter: it remembers where it's cleaned and continues where it leaves off while running back to the base station to empty and recharge. Fourth, my older one keeps getting stuck hanging off a stair or wedged in a corner between furniture; this i7+ has not hung up on a step yet, and has managed to extricate itself from several tight spots. Lots of improvements!As for the auto dirt disposal system, so far it's worked fantastically. Either under control of the app or the robot, the vac snuggles in to the charging station and a vacuum starts up (quite noisy compared to the robot...about the same as a regular vac) and sucks all the dirt from the robot dirt container into the bag in the upright unit. It takes about 15 seconds, and a quick inspection shows it does a really nice job of emptying the robot. every now and again you still need to go in and give the rollers a clean (especially if you have pets, like I do) and wash out the dirt bin, but I am doing that once every two to four weeks, which is fine. As for the dust bin in the receptacle, it tends to last about four weeks (the first house cleaning it filled in two days, but four dogs and a cat were the reason). I suspect without pets I would only replace the bag every month of two. The bag itself is a clever design with a sliding door to ensure you don't spray dirt all over when you remove the bag.I've been really impressed with this i7+. Its' not caused one issue so far, and while that's too good to last, I'm delighted with the system. So much so that I'm considering a second for the other floor of the house. This isn't inexpensive, but when I think I pay office cleaning staff to do the same job vacuuming the floor, this pays for itself in a month! I've read lots of negative comments in posts here and elsewhere, but so far, I have zero to complain about.Update: After two years, these i7s are still working perfectly. I have several s9+ too, and they are a pain to work with; they always jam, stop working, and report dirty sensors every day. The i7s just work, perfectly. I will be replacing my s9s with i7s. I can't recommend the i7+ enough!

It does a great job at vacuuming. I was disappointed in the mopping part. It barely goes over the floors with a damp cloth. Does not clean them.UpDate. It stopped working. I had this for a month and it stopped working. Sending it back

No cumple con la descripción, envió un producto que únicamente aspira, por si eso fuera poco, para devolverlo me hicieron pagar el envío el cual costó $2650 pesos mexicanos, el cual me dijeron en llamada telefónica que me reembolsaría de manera inmediata al enviar el comprobante del gasto, sin embargo, al enviarlo me respondieron con un correo mencionando sus políticas de reembolso mismo que puede tardar hasta 35 días posteriores a la llegada del producto devuelto, cosa que me parece insultante ya que el error no es atribuible a mi persona, por lo pronto ya pague más de $10,000 pesos mexicanos y no tengo ni el producto ni el dinero, PÉSIMA ATENCIÓN POST-VENTA para solventar errores de AMAZON, PROVEDORES Y GENTE DE LOGÍSTICA.

I don't know what is the customer segment for such a product, but this was not for me.Doesn't pick up hairs, granola or rice from the hard floor. Triangle brush got stuck in the wheel itself and entangled all hairs in it. Mopping is a nightmare, does not work at all. After seeing the hardwood performance, I don't think it can work anything at all on the carpet. Returned in 3 days.

Buen producto, hace su tarea.Hay ocasiones q no cumple con laLimpieza de algunas áreas, como se configura en la aplicación

Very very bad performance and gives wrong indication
