Which is better for pet hair?

The Maxim claims 22,000 Pa and a tangle-resistant brush, so it should pull more hair off hard floors. The j9+ is the safer pick on carpet because its mop lifts out of the way.

Is the Roomba Combo j9+ worth the extra money?

Only if you have a lot of carpet or low furniture. At $1,399.00 at Lowe's as of November 7, 2026, it costs far more than the Maxim's $249.99 low, and most of that premium buys navigation and carpet handling, not raw suction.

Which handles carpets better?

The j9+. Its mop pad retracts when it senses carpet, so it can vacuum rugs without wetting them. The Maxim avoids carpet while mopping and is rated for low-pile only.

Which needs less maintenance?

The Maxim's 0.79 gal bin and self-washing mop dock mean fewer trips to empty and clean. The j9+ bin is only 0.08 gal, so it relies on the dock emptying often.

Which works with more smart home systems?

The j9+ supports Google Assistant, Amazon Alexa, and Apple Siri. The Maxim supports Google Assistant and Amazon Alexa only.

Which is better for apartments with hard floors?

The Maxim. Hard floors are its strength, the dual spinning pads scrub better than a single pad, and the price gap is large.
