This is BEST Robovac you'll ever own, IMHO. I purchased the first robovac made by a different company when these little things were a completely new concept. It was such a surprise as to how good it was, and how it made a difference in time spent housekeeping every day. I've been a fan ever since (20+ yrs) and have tried many different brands and models. The Eufy is the best! And I have purchased 3 of this model. Depending upon your budget and specific needs, there are things I've learned, and I'm going to break those points down for your consideration. Possibly they may apply to your situation. These points are some requirements that make all the difference to me and my lifestyle. ~~>#1. Two auxiliary brushes.: This is the most important thing for me and is a no brainer, IMHO. The two brushes, one on each side of the front edge (approx 11 and 2 o'clock) sweep the debris to the underneath center of the unit where it is sucked up. Because there are two, they sweep a larger area, and because the vac covers the same areas more than once, you get better cleaning results. This is very important in kitchens and high traffic areas. Also corners are swept from both sides.#2. Undercarriage rotating beater brush: I have both carpeted and uncarpeted areas. I need more than just suction to lift dust, pet hair, dirt, and debris from my floors. My kitchen does not have carpet so an undercarriage beater brush is not a requirement, but my Family room has carpeting, and my Living room has Oriental wool and silk rugs. They need a light agitation to help lift up the dust so the vacuum can easily suction it up. A beater brush is a major requirement for my floors for this reason.#3 Scheduling option: this is WONDERFUL! Our major living areas are scheduled to vacuum after we've gone to bed, and our bedrooms and bathrooms are scheduled while we are gone during the day. Happy feet!#4. Rechargeable on its own! Need I say more? It goes back to the recharging station to recharge itself when it needs more juice. YAY! We live on three floors, and this is a huge plus for us.#5. The Customer service with this company is amazing! If you have any issues, regardless of how small, they will get back to you, and immediately help. They respond, and do not merely send you to a FAQ link.#6. It is gentle and does not smack into your furniture, scuffing it.#7. The more you use it, the cleaner your house will be. Regular dusting is done on a daily basis so there is less and less dirt and dust to deal with. It is amazing the difference! Weekend freedom!#8. You do not have to do much prep at all, just check for loose cords to not become tangled. When I bought my first robovac I didn't use it too often because I was unnecessarily moving furniture, rugs, floor lamps, trash cans, etc. Then one day, I left a door open and the robovac sneaked out of the room I'd religated it to. When I returned home, the little vac had done my whole house (single level @ 2000 sq feet) and it was GREAT. I realized that all I needed to do from then on was to let it go do its thing. Lesson learned. My Eufys are my workhorses and I recommend this little gem of a vac if you are considering it. IMHO It will be a good investment. It has been for me, and my family (including cats and dogs).
