Roomba 770 vs 870 – Thorough but Loud Cleaning

The Roomba 770 vs 870 highlights the difference between the budget-friendly low-profile Roomba iRobot 770 and the mid-range 870 with longer battery life but larger clearance height. Both models are designed for cleaning hard floors and carpets; they lack mapping but have protective bombers to avoid damage because of touching the obstacles.

Suction and dustbin capacity

In my review, I’d like to draw attention to vacuums’ 3-step cleaning and the AeroForce system that allows removing approximately 98% of the dirt. The Roomba 870 has claimed 1,000 Pa max suction while the company doesn’t offer specifications for the 770 model. However, both models demonstrate good suction power despite the lack of carpet boost technology.

The Roomba 870 features a dust container of 1,000 ml while the 770’s storage compartment is only 260 ml that makes a user empty it several times per session.

Using area

The Roomba 770’s charge lasts about an hour and a half, allowing the unit to move from one room to another and to clean the whole house with three bedrooms on a single charge. The Roomba 870 features the stated 1,000 feet per 120-hour charge. Still, the using area is dependable on how much dirt is on the surfaces. Besides, one can set a vacuum to a spot mode or use it to clean lots of carpets. All these factors reduce the using area since they require more power.

Noise level

Both models are rather noisy despite the small difference between their decibels (the Roomba 770’s 60 dB versus the 870’s 61 dB). So they are pretty loud.

Carpet cleaning

The test of the Roomba 870 vs 770 hasn’t revealed an essential difference in their ability to clean soft surfaces. Both models cope with low-pile rugs. They lose power and cannot handle deep cleaning on carpets with long fibers. Both models come with branded silicone spindles that remove various types of fur without tangling with hair. Besides, they go from the hardwood floor up onto the carpet and back hassle-free.
