  1. Hi,

    I am interested in getting the Ecovac Deebot X1 Omni and was wondering if this would be good on porcelain tile floor. I also wanted to know if we can put into the water some detergent.

    Thank you

    • Yep, it will work great on most any tile.

      Regarding detergent, I believe Ecovacs sells a specific detergent that’s safe for it. However, I don’t know of any others you could use.

  2. Hello Derek, you made a very interesting review of the window vacuum cleaner Hobot 298. Have you or can you make a comparison or review of the new Hobot 388. There is very little information on this matter of automated window cleaners so your insights are more than helpful. All best

    • Unfortunately, I haven’t tested the 388. If it’s anything like the 200 series, I imagine it’s just a better version.

      Of the HOBOTs we’ve tested over the years they do seem to get notably better with each new iteration.

      Unfortunately, I don’t believe we’ll be able to test the 388 soon as we’re a bit overwhelmed trying to test security systems currently.

  3. Hello. Last year I bought the pure clean Robo vac. Impressive. Your review – detail etc – very impressive. Mine has packed up after 12 months. Goes round in circles. What about your device? Did you carry on using it? If someone is a good engineer it will have a simple solution as clearly one wheel has weaker traction hence the circular motion…

    • Unfortunately, we didn’t have the tester resources to continue using the Pure Clean. I believe we gave it away in a giveaway.

      I would suggest you disassemble the robot and see if their is hair or other debris stuck in the wheel. That’s fairly common with robots like this.

      Also, take the battery out for a few minutes for a hard reset. If it’s a software issue that may help to resolve it.

  4. Thanks for your interestingd comparisons,

    I don’t see Ecovacs Deebot Ozmo 950/960/930… Lenovo X1

    Hope to reviews them

    All the best

    • Thanks for your suggestions. I will add those to our “to review” list and see if we can get some of those models in our testing queue.

  5. The Deebot N79 has two power levels. Did you try it on high (as recommended) for the harder to get materials? I’m also interested in a review of their laser-mapping models.

    • If I recall correctly, we only used it on auto mode during those tests. Our more recent tests have started to use max modes wherever available. I would suspect an increase in performance for the sugar tests if / when we’re able to re-run the tests on the N79.
