As compared to the 960 model - wow
I've had many robot vacuums in my lifetime-- including several Irobot Roomba and several other brands. I recently went through some upcycling of my fleet, giving some way, buying some new and realizing that in the used / open box / refurb market there are AMAZING deals to be found. I started with the 692-- basically the same as my old model with a new face, no carry handle, then on to the 960 and 981.In all of the different models the 981 was tops on a couple points that are very interesting if you are comparing the 960 to the 981-- I was able to get the 692, 960 and 981 all for the same open box price-- and a huge difference in features & functions between the three-- so here I am to tell you like for like dollars, the 981 is the clear winner with a few points to be aware of.The 981 is superior to the 960 in the following ways:-Multi power operation: it can automatically run hi/low automatically based on dirt level or surface being run on -- I'm not sure-- it runs on high on carpet and low on wood-- most of the time it's low on wood or hard surfaces-Higher capacity battery - due to the dual speed operation it can have a shorter max run time on the low end but a higher run time on the high end depending on how much low/high running it does-Seems to have a dual exhaust dirt bin while my 960's have a single exhaust bin. I have still had a very difficult time substantiating this difference and trying to find replacement parts to more deeply understand this difference-It definitely cleans more deeply than any robot vacuum I've had in the past-- the carpet ends up standing straight up like it does from a traditional vacuum cleaner and after many years and robots this is a first! Surprising difference between the 960 and 980 series!Logic-wise, and as expected, the operational mode of this unit is essentially the same as the 960-- neat rows, less banging around against objects and devices as compared to past models.I won't go into more as my goal here was really to compare the 960 and 981 and the value that is to be had in the used/ warehouse / refurb market on this particular model-- coming in at the identical price between 981, 960 and 692 models which was shocking.I'm not here to argue any comparison to the i7 which I keep my eye on as well and in the warehouse / refurb / used market is never anywhere near the value that this model has been.While I'm here, also to remark every used / warehouse / refurb model I have ordered has been pristine condition with not any indication of use in any way. This model is the keeper after proceeding through several others discovering that better models were the same price.One negative thing about the dual speed dual strength vacuuming feature: The feature is great, but it makes a difference continually in the sound that you hear in the home as cleaning happens-- so in some ways what you gain from the feature you lose in disruption or varying sound / pollution for those who are more sensitive to the sound of HIGH/LOW/HIGH/LOW many many times per minute throughout the cleaning cycle, especially if you have hard floors with various rugs that cause it to continually speed up and slow down, etc.Ver másVer menos
