I have owned a few robot vacuums over the years and the Shark Power Detect 2 in 1 is honestly my favorite. The fact that it’s a vacuum/mop comb with hands free emptying of dirt and filling of mop water is so convenient! The dirt is trapped using HEPA filtration and only needs emptying every 60 days. I have 3 kids and 2 dogs, using my shark twice daily, once to vacuum and at night to deep clean ( vacuum and mop ) takes a lot off my plate as a stay at home mama. Another feature I love is whether it needs to refill water, empty dust pan or recharge (which she will inform you what she’s doing) she goes right back where she left off to complete the job. Lastly, this vacuum duo is much quieter than the competitor, which is always a bonus!! Hands down if you’re in the market for a robot vacuum.. this is the one!!
