DEXP LF-800

We continue to review robot vacuum cleaners from various manufacturers, and today we present to you an interesting model, the DEXP LF-800, with a retail price of around $160. In terms of appearance and performance, the new robot surpasses its predecessors (DEXP LF-200 And DEXP MMB-300), which is impossible not to note. To confirm this, let's look at the description of the model's main features.

Equipment

The DEXP LF-800 delivery set includes:

1. Robot vacuum cleaner.
2. Charging dock.
3. Network adapter.
4. Remote control.
5. Turbo brush.
6. Side brushes (4 pcs.).
7. Dust collector.
8. Filter.
9. Washing module.
10. Microfiber cloth (2 pcs.).
11. Operating instructions.

The included instructions are minimally simplified, but they briefly outline the main parameters and functions. A motion limiter is not included.

The robot is delivered in attractive packaging with information about the device printed on the edges. The box dimensions (LxWxH) are 585x135x390 mm. A plastic handle is included for easy carrying, and a seal is included to prevent accidents.

Appearance

The robot vacuum cleaner has a modern and stylish design. The DEXP LF-800's round body is available in two colors: silver-gray and a trendy rose gold, the hue of which can change depending on the lighting (it appears pink in sunlight and orange-gold in light).

Viewing the robot vacuum from above, we see a row of control buttons and an LCD screen displaying the current status and program settings. Also on the top panel is a button for removing the dust container, which slides out from the side. Additionally, on the side is a protective bumper with obstacle sensors, a power button, and a port for connecting the power adapter and charging directly from the wall.

On the underside of the DEXP LF-800 robot are the charging contacts for the docking station, two side brushes, a turbo brush, a battery compartment, a cluster of four cliff sensors, and a three-wheel propulsion system. This system consists of a free-spinning front roller and two side drive wheels with built-in motors. Small motors are attached to a spring-loaded chassis for successful obstacle avoidance. Each wheel is mounted on a rubber tire with a tread, allowing it to navigate difficult terrain and avoid slipping on wet floors.

Functional capabilities

The DEXP LF-800 robot's dust collection system consists of two side brushes and a central turbo brush. The side brushes are designed as follows: three 5-centimeter-long brushes with 36 bristles each. The brushes rotate synchronously, from the outside in, collecting dust and small debris in a strip approximately 33 centimeters wide. This arrangement on the body is designed for more effective cleaning of dirt from inner corners.

The brushes appear identical at first glance, but they are slightly tilted/bent in the opposite direction of rotation. Each brush must be installed in its designated slot. This is indicated by the L and R markings.

After debris is collected by the DEXP LF-800 robot vacuum's side brushes, it moves to the central turbo brush. Remarkably, the turbo brush mechanism is disassemblable: it can be disassembled for cleaning and washing, as well as for removing small objects that get stuck.

After the turbo brush, the airflow containing collected dust and debris passes through the inlet and is directed into a dust collector with multi-level filtration. The first coarse filter is a nylon mesh filter for visible dirt particles. Next, a foam pad is installed for medium-sized particles. Finally, a paper filter captures the finest dust.

Overview of the operating modes of the DEXP LF-800 robot vacuum cleaner:

• classical;
• local;
• around the perimeter;
• auto.

One of the robot vacuum cleaner's modes is wet floor cleaning. To use it, simply install the cleaning module in place of the dust bin and secure the microfiber cloth with Velcro around the perimeter and elastic bands sewn into the sides. Liquid from the tank is supplied to the cloth under pressure, allowing you to regulate its flow rate and the degree of wetness of the floor surface. The water supply stops when the unit is disconnected.

The robot is controlled using buttons on the body, an IR remote control, and a smartphone or tablet via the DEXP Robot app (download it from the App Store or Google Play). The only caveat is that the robot vacuum is controlled via a router rather than directly from the smartphone. Otherwise, the controls are intuitive and easy to use. You can also set a cleaning schedule.

Advantages and disadvantages

As per tradition, we conclude our review with a list of the advantages and disadvantages of the DEXP LF-800 robot vacuum cleaner.

Pros:

1. Low price.
2. Compactness.
3. Stylish appearance.
4. Different operating modes.
5. Wet cleaning (+ full-fledged washing module).
6. Large dust collector capacity.
7. Control via mobile application.
8. Easy to find consumables.

Cons:

1. There is no movement limiter.
2. The application is malfunctioning.
3. Primitive navigation.
4. It takes a long time to charge.

Overall, the model is suitable for small spaces. The manufacturer claims it can clean up to 200 square meters, but in reality, due to the lack of a lidar or camera, as well as the ability to resume cleaning after recharging, the robot won't be able to clean this area. It's well-suited for cleaning areas up to 80 square meters. Considering its specifications and features, the model isn't the best in its class, but it's not bad either. It's a middling performer with standard functionality.
