  2. Complains about buggy software program: Studying the critiques part, I seen a number of folks complaining about software program bugs that may trigger the robotic to get caught in tight spots.

Roomba 960

Verify Worth

The Roomba 960 is the same product to the 980, however with a smaller motor and battery.

It has the identical iAdapt 2.Zero navigation because the 980, however with worst efficiency on laborious flooring (at the very least for cleansing sand) because of the lack of airflow.

The camera-based VSLAM system is a departure from the random shifting Roombas, so this robotic is far more environment friendly.

It’s the most cost effective sensible navigating Roomba, however it doesn’t have the sensible imprint system, so it doesn’t save the maps. The Roomba 960 gained’t be capable to clear a particular space like a Roomba I7 or S9.

This mannequin additionally doesn’t have a clear base, so that you’ll must empty the mud cup after each cleansing cycle.

Surprisingly, the Roomba 960 performs higher on carpet than the Roomba I7 based mostly on embedded sand checks so it’s a good choice for houses with such.

Benefits of the Roomba 960

  1. Most cost-effective Roomba with Good Navigation: The Roomba 960 is the least costly Roomba robotic with the upgraded navigation system that goes in a predictable forwards and backwards sample.
  2. Cleans carpet nicely: Regardless of the low airflow, the 960 did nicely at cleansing carpet with a 91% rating.

  2. Brief run time: This robotic will run for less than 75 minutes, however the recharge and resumes make up for it.

Design of the Roomba S9 and 960

On this part, we’ll have a look at the similarities and variations between the S9 vs. 960, and there may be a lot to speak about right here.

Roomba S9 Design

Roomba S9 Design

One factor that stands out with the Roomba S9 is the form.

Gone is the spherical design that customers have recognized ever since iRobot began manufacturing robotic vacuums greater than 20 years in the past. As an alternative is a D-shape design that brings a whole lot of advantages.

It’s like placing the effectivity of Neato and the high-tech gadgetry of the I7 in a single robotic.

The sq. entrance permits iRobot to place in wider brushes (to be extra particular, extractors), and reposition the facet brush.

These design adjustments, together with the 3D time-of-flight sensor, drastically enhance how the S9 cleans edges and corners, which was a weak level with earlier Roomba fashions. It additionally improves the way in which it navigates round tight spots.

Prime view

Top view of the Roomba S9

On the middle of the robotic is a spherical gold disc that’s the quilt for the mud cup. On the higher proper are the buttons (three in whole) for the house, auto clear and spot clear operate.

In entrance is one other sensor that helps the S9 precisely draw the maps and pinpoint the placement of the charging station.

Behind the golden disc is the digicam that’s central to the S9’s navigation system.

Backside view

Bottom view of the Roomba S9

The S9 has vast extractors which are 30% wider than the I7 that spans virtually the whole width of the robotic.

Comparing the S9 and I7 brush rollThe Roomba S9 brush roll is 30% wider than the I7 as seen within the comparability above. This provides the S9 higher efficiency at cleansing corners.

One other change from the I7 is the location and design of the facet brush. Within the Roomba I7, the facet brush sits in entrance of the principle brush whereas the S9 is positioned nearer.

It additionally has extra prongs (5 to be precise) that rotates at a slower tempo. The change prevents it entrance flinging massive particles of filth round, which is a matter with the older Roomba fashions such because the 690, 890, and even the 960.

Behind the principle brush is the opening for the clear base station to suck out the contents of the mud cup.

Solely the “plus” model has this slot, whereas the bottom model (with out the “plus”) doesn’t have it.

Roomba 960 Design

Roomba 960 Design

The Roomba 960 retains the form of the Roomba 800 and 600 sequence robots. It has the identical design cues because the costlier 980 however with a lighter colour scheme.

One drawback of the spherical form design is its poor decide up on edges.

It additionally limits the dimensions of the comb and the robotic wants extra passes to scrub the identical space because the S9.

Prime View

Top view of Roomba 960

The 960 has a minimalist design with solely three buttons – the clear, residence, and spot clear. All the capabilities akin to scheduling is accessible contained in the app.

iRobot has ditched the scheduling buttons on the robotic as a result of shoppers didn’t discover it simple to make use of.

Behind the clear button is the on-board digicam that’s the main sensor for the upgraded navigation system.

The mud cup slides in on the again and the notch you see is the discharge button that unlocks it.

Backside View

Bottom view of the Roomba 960

The 960 design is much like the 980, and 800 sequence robots. It has a single facet brush proper in entrance of the rubber extractors on the again.

Roomba-I7, 960, and 890 Comparison

You’ll discover that every one three fashions from completely different Roomba generations have the identical format on the subject of the place of the parts. The distinction can be from the 890 to the I7 is the grooves on the extractors, what’s contained in the robotic and the software program.

Similarities and Variations of the Roomba S9 and I7

Now let’s have a look at how comparable and completely different these robots are.

Similarities of the Roomba S9 and I7

  • Good navigation: These robots use the VSLAM (or Visible SLAM know-how) that depends on a digicam to map its precise location and assist it keep in mind areas cleaned and never cleaned.
  • Recharge and resume: Each fashions will resume cleansing after recharging if it has not accomplished cleansing the whole stage.
  • WiFi and Smartphone app: Nearly all of the controls for these two merchandise are within the iRobot Residence App the place you’ll be able to schedule, alter energy, verify standing, and far more.
  • Suitable with Alexa and Google Assistant: There’s an choice to make use of voice to regulate these robots by means of Alexa or Google Assistant, whichever app you like.

Variations between the S9 and 960

  • Persistent maps: The S9 has sensible imprint navigation (a.okay.a. persistent mapping) that saves the map that the robotic attracts within the cloud. This characteristic offers customers the choice to pinpoint areas to scrub at particular instances.
  • Form: The 960 has the spherical form, narrower extractors, and a three-prong facet brush whereas the S9 has a D-shape design with the broader extractors, and a five-prong facet brush that works higher at cleansing edges.
  • Auto filth disposal system: The S9 has the “clean base” station that routinely empties the filth canister utilizing a second vacuum contained in the dock.
  • Extra airflow: The S9 has a better airflow with 22 CFM whereas the 960 tops out at 9 CFM. This disparity exhibits within the laborious flooring cleansing checks the place the S9 does quite a bit higher on the subject of cleansing sand.
  • Worth: The Roomba 960 prices virtually a 3rd of that of the Roomba S9+, which is staggering.

How do the Roomba S9 and 960 navigate?

When the 980 was launched, it was a landmark second for iRobot as this mannequin was the primary Roomba product that had sensible navigation making it extra environment friendly than earlier fashions.

Not will it pinball in a random route, however it goes in a straight forwards and backwards cleansing sample able to cleansing a bigger space with higher proficiency.

Roomba 960 Navigation

The 960 makes use of that very same sensible navigation able to making a map of your property and utilizing it to pinpoint its precise location.

On prime of the robotic is a digicam (angled at 45 levels behind the “Clean” button) that aids it to find essentially the most environment friendly path across the residence

The information gathered from the digicam goes to the VSLAM software program that builds the map and retains monitor of the robotic’s place.

Round and beneath the robotic are sensors that help it to keep away from obstacles and fall from cliff factors.

Notable of those sensors is the ground monitoring sensor that helps the software program monitor the robotic’s place.

This characteristic additionally offers the 960 the power to recharge and resume when the battery runs low.

So the 75 minute run time of the 960 gained’t be a lot of a difficulty.

The digicam frequently takes snapshots of its setting and appears for distinctive options because it strikes.

This helps it monitor keep in mind areas it has cleaned and areas it hasn’t.

Roomba S9 Navigation

One distinction between the Roomba S9 and the 960 by way of navigation is the power of the S9 to avoid wasting the maps it attracts.

iRobot calls this sensible imprint mapping. This characteristic takes all the information from the digicam and entrance sensor to attract maps.

The S9 has a particular “training mode,” the place it simply navigates across the space with the vacuum motor off.

Having the motor shut helps preserve battery life and permit the robotic to cowl a bigger expanse.

The flexibility to avoid wasting maps has a number of advantages. One in every of which is it permits shoppers the choice to scrub a particular room or space.

You should utilize this at the side of Alexa or Google play. For instance, you’ll be able to say, “Roomba, please clean the living room,” and the robotic will solely clear that space.

It brings usability and comfort to the subsequent stage.

The S9 additionally has a brand new sensor on the entrance bumper referred to as the 3D time-of-flight sensor that always scans what’s forward at a charge of 25 instances per second. This sensor helps the S9 get shut (millimeters shut) to scrub the perimeters and corners of rooms successfully.

It additionally helps the robotic navigate round tight proximity higher and keep away from bumping laborious into shiny or reflective objects.

How does the Roomba S9 and 960 clear?

By way of cleansing, each these robots use the identical three-stage system that makes it among the best performing robotic vacuums based mostly on client critiques.

The Roomba S9 and 960 depend on a single facet brush, counter-rotating extractors, and suction from the motor behind it to choose up filth.

iRobot has a patent on the rubber extractors so I doubt that you simply’ll see it in every other model.

It’s among the best at choosing up filth, particularly on carpets the place it doesn’t rely an excessive amount of on airflow.

Each robots have acoustic sensors that “listens” to the quantity of filth picked up. The extra noise it detects, it tells the robotic to do extra passes and improve suction.

Roomba 960

The 960 nonetheless makes use of the outdated three-pronged facet brush with the lengthy bristles to funnel filth on the edges in the direction of the principle brush.

One concern with the 960 facet brush is the rate of which it spins. It tends to scatter filth slightly than cleansing it. The robotic ultimately picks up filth that it scatters, however it’s annoying.

Behind the facet brush is the principle brush or extractors that counter-rotate to agitate and clear filth.

Roomba robots have scored constantly excessive in cleansing checks, and these two brushes are a giant purpose why.

Roomba S9

The S9’s design is vastly completely different from the 960, I7, and different Roomba merchandise earlier than it.

It has a wider brush (by 30%) and a extra compact facet brush that has extra arms.

The adjustments intend to enhance how the robotic picks up filth alongside the perimeters and general effectivity.

Cleansing checks present that the S9 performs significantly better at cleansing corners, deep cleans higher, and tangles much less.

The facet brush additionally spins at a slower tempo, so it doesn’t unfold as a lot filth round because the 960 did.

Not solely will the S9 clear autonomously, however it additionally empties the bin by itself because of the clear base station.

iRobot says that the bag inside can maintain an equal of thirty S9 bins, in order that’s nearly a hands-free gadget for as much as a month relying on how a lot filth it tackles and protection.

This characteristic is simply out there with the “plus” model that’s far more costly.

Cleansing efficiency

Regardless of the ability discrepancy, the Roomba 960 isn’t too far off from the S9 on the subject of cleansing with some exceptions.

Roomba S9 will carry out higher general

The excessive airflow, wider extractors, and higher facet brush design make the S9 a greater robotic on the subject of cleansing completely different flooring varieties.

The S9 has 22 CFM, which greater than triples the 960’s 9 CFM.

That is felt most in cleansing non-carpet surfaces.

It should decide up many of the filth on laborious flooring from mud to massive stuff like Fruit loops. The vast brush additionally helps it resist tangles higher than the I7 and 980.

Nonetheless, with the comb sitting decrease to the bottom and having a tighter tolerance, it doesn’t decide up Fruit loops as easily because the I7 did. It should clear them up, however you’ll hear a “crunching” sound from the extractors crushing it.

On the plus facet, the brand new brush design offers the S9 excellent efficiency on the subject of deep cleansing carpet. In a take a look at executed, it was capable of decide up round 94.5% of sifted sand on medium-pile carpet.

It additionally does a superb job of choosing up floor particles on carpet. No matter dimension, the S9 will decide up stuff like Cheerios, quaker oats, sand, mud, and hair nicely.

The redesigned facet brush does a greater job of directing filth in the direction of the principle brush and never kick it round.

Roomba 960 works finest on carpet

The low airflow of the 960 is felt most on laborious surfaces. It might decide up mud, and Fruit loops with out points, however on the subject of cleansing sand, it’s going to wrestle immensely.

Cleansing checks reveal that the 960 did poorly at cleansing sand.

Roomba 960 on Hard Floor

The fast-spinning facet brush is also one other concern because it tends to kick filth round slightly than decide it up.

The place the 960 stands out is cleansing filth on carpets – whether or not it’s floor or embedded filth.

The most important shock for me is how nicely it picked up sand on carpets. It was capable of rating 91% at cleansing 100 grams of sand, which is best than the I7 that solely scored 79%.

The underside line

Whereas the Roomba S9 did higher general, it’s laborious to miss what the 960 is able to on carpet. In one of many largest surprises in my vacuum reviewing profession, it scored a 91% at cleansing embedded sand on carpets.

When you don’t thoughts the dearth of the sensible imprint characteristic and need a  moderately priced robotic that cleans nicely on carpet, then the 960 is a wonderful choice that prices solely a fraction.

One benefit that the sensible imprint system has is the hands-free comfort that it brings to the desk. Not will it’s a must to empty the robotic’s mud cup.

Keep in mind to observe these steps to arrange your property for the Roomba to do its finest work.

How lengthy will the Roomba S9 and 960 run?

The 960, with its smaller Li-ion battery, will run for less than 75 minutes.

This lack of vary doesn’t hinder it because of the recharge and resume characteristic the place the robotic resumes operation if the battery runs low at any level within the cleansing cycle.

As soon as the battery is low, it recharges and resumes cleansing the place it left off.

The S9, because of its larger battery, will run longer – as much as 120 minutes. Once more, how lengthy it runs gained’t be a lot of a difficulty as a result of these are sensible navigating robots that may resume cleansing after recharging.

However the added vary, makes it higher suited inside bigger houses.

Mud cup comparability

The Roomba 960 hundreds from the again of the robotic whereas the S9 mud cup sits within the center and is accessible by opening the gold disc on prime.

In the case of capability, the 960 is greater with a 600-milliliter capability.

The S9’s plus bin can solely maintain as much as 400 milliliters.

Even with the smaller capability, the S9+’s computerized filth disposal system negates the disparity because it empties the bin for you.

So it may go additional with out intervention.

Upkeep and operating prices of the S9 vs. 960

The autonomous high quality of a robotic doesn’t imply it’s maintenance-free.

Objects just like the sensors, mud bin, and brushes want periodic cleansing to maintain it in tip-top form.

The S9 with the broader brushes are extra resistant it hair wraps, however you’ll must verify it periodically in order that it lasts so long as potential.

Since there’s friction, this half will ultimately put on out and there’s no precise timetable when to interchange it. iRobot says one 12 months, however it may go longer.

Battery [depends]

All new Roomba vacuums may have Li-ion batteries of various capacities. The S9 comes with a big capability of three,300 mAh li-ion battery that may run for as much as 120 minutes.

These batteries ought to final for at the very least two or three years with correct upkeep, akin to retaining it plugged in when in use or disconnecting the battery from the robotic should you’ll not be utilizing it for an prolonged interval.

One benefit of the Roomba over different manufacturers is the supply of batteries from iRobot and the aftermarket. Changing the battery is a straightforward activity requiring solely fundamental instruments.

Full bin sensor [every two weeks]

There’s a sensor contained in the mud cup that wants some TLC each couple of weeks. It’s the total bin sensor that fires a sign to the app that the bin is full.

Castor wheel [depends]

One other half that will get a whole lot of abuse is the castor wheel. For the 960, it’s the wheel in entrance of the principle brush that helps steer the robotic. Within the S9, it’s behind the rubber wheels.

This half will collect a lot, filth, and hair and it’s important that you simply usually clear this to maintain the robotic operating easily.

The frequency will depend upon the setting; simply usually give a visible verify.

What’s the dimensions distinction between the Roomba S9 and 960?

The Roomba S9 measures 12.5 inches vast and three.5 inches tall whereas the 960 measures 13.eight inches vast and three.63 inches tall making it the larger robotic.

Spec comparability between the Roomba S9 and 960

Which robotic do you have to purchase?

Selecting between these two fashions will depend upon these components: the sum of money you’re prepared to spend, and the options you worth essentially the most.

There’s no query that the Roomba S9 is the superior performing robotic throughout because of the adjustments in design and software program.

It should decide up filth higher on laborious flooring as a result of it has extra airflow. Nook and edge cleansing are additionally superior to the 960 due to the broader brush and the sq. entrance design that does higher on these areas.

The improve in navigation because of the 3D time-of-flight-sensor is one other improve that makes the S9 hug the perimeters and goes round furnishings higher.

Although there are some who might disagree in you verify the critiques.

The most important variations between the S9 and 960 are the sensible imprint system and auto filth disposal that makes the S9 a really autonomous family helper.

The latter eliminates the tedious activity of getting to empty the mud cup. And the sensible imprint system permits shoppers the choice to scrub choose areas to scrub within the residence utilizing the app or voice.

This comfort is solely not potential with the Roomba 960. However all these options will come at an costly premium. When you’re prepared to spend for it then by all means.
